This equipment generates and uses radio frequencyenergy, and if not installed and used properly (that is,in strict accordance with the manufacturersinstructions), may cause interference. The OmniScanMX has been tested and found to comply with thelimits for an industrial device in accordance with thespecifications of the EMC directive. However, itshould not be used in a residential, commercial, orlight industrial environment.

SafetyThis instrument is an instrument of Class 1 andinstallation category II. Before applying power, verifythat the correct safety precautions are taken (see thefollowing warnings). In addition, note the externalmarkings on the instrument that are described underSafety Symbols and Notes.

Warnings Carefully read the instructions contained in the

users manual prior to powering on theinstrument.

Keep the users manual in a safe place forfurther reference.

Follow the installation and operationprocedures.

Imperatively respect the safety warnings on theinstrument and in the users manual.

Before turning on the instrument, you mustconnect the protective earth terminal of theinstrument to the protective conductor of the(mains) power cord. The mains plug shall onlybe inserted in a socket outlet provided with aprotective earth contact. You must not negatethe protective action by using an extension cord(power cable) without a protective conductor(grounding). Grounding one conductor of atwo-conductor outlet is not sufficient protection.

Only fuses with the required rated current,voltage, and specified type (normal blow, slowblow, quick acting, etc.) should be used. Do notuse repaired fuses or short-circuited fuseholders. To do so could cause an electric shockor fire hazard.

Whenever it is likely that the ground protectionis impaired, you must make the instrument v

inoperative and secure it against any At the static-safe workstation, follow these

unintended operation.

The instrument must be connected only to apower source corresponding to the typeindicated on the rating plate.

If the equipment is used in a manner notspecified by the manufacturer, the protectionprovided by the equipment may be impaired.

Do not install substitute parts or perform anyunauthorized modification to the instrument.

Service instructions, when applicable, are fortrained service personnel. To avoid dangerouselectric shock, do not perform any service unlessqualified to do so. For any problem or questionregarding this apparatus, contact R/D Tech inc.or an authorized R/D Tech representative.

Electrostatic Discharge PrecautionsIf, for any reason, you have to disassemble yourinstrument or touch any internal component, makesure you take all the necessary precautions againstelectrostatic discharges (ESD). Electrostaticdischarges may be responsible for damaging or evenblowing electronic components in your system.Electrostatic damage to components can take theform of upset or even catastrophic system failures. Inaddition, omitting to take appropriate precautionscould void your limited warranty.

The basic rules of ESD control are:

1. Handle ESD-sensitive components only inprotected work areas. Always ground yourselfwhen handling ESD-sensitive components orassemblies. Be sure to use the propermaintenance and work procedures inconjunction with the type of material.

2. Always use a conductive or shielding containerduring storage or transportation of ESD-sensitive components or assemblies (for ex.,printed circuit boards). The materials used mustcreate a Faraday cage, which will isolate thecontents from electrostatic charges.

3. Open ESD-safe containers only at a static-safeworkstation. Such a workstation will includeequipment to perform the three criticalfunctions: grounding, isolation, andneutralization.

procedures before beginning any work:

Put on your wrist strap or foot groundingdevices.

Test your grounding devices, to ensure that theyare functioning properly.

Check all grounding cords to make sure they areproperly connected to ground, ensuring theeffective dissipation of electrostatic charges.

If you have an ion generator, turn it on. This willhelp dissipate static charges from anynonconductive materials.

Make sure that your work surface is clean andclear of unnecessary materials, particularlycommon plastics.

When handling electronic devices, hold thecomponents by the plastic edges. Avoidtouching the metal leads.

When passing loaded boards or componentsbetween individuals, both individuals must begrounded to the same ground point or potential.

Avoid bringing components in contact withyour clothing, hair, or other nonconductivematerials.

The above procedures are only a summary of themeasures to be taken against electrostatic discharges.Please consult the literature dedicated to that topicfor more details.

2 Choose the desired inspection application by pressing the F key corresponding toone of the buttons appearing on the OmniScan splash screen.

Note: If the system encounters a problem during its boot-up phase, the powerindicator light identifies the nature of the problem by using a color code (fordetails, see Power indicator light in section 2.1.9, p. 13).Basic Operation 17

To turn off the OmniScan Press for three seconds.The power indicator light becomes orange while the OmniScan is shutting down.

3.2 Power Supply Management

The OmniScan is a portable instrument and it can draw power either from Lithium-Ion batteries or from a DC power adapter.

3.2.1 Lithium-Ion BatteriesThe OmniScan can store up to two batteries, but it only needs one to be operational. Iftwo batteries are present, the OmniScan will operate from the least charged battery bydefault and it will automatically switch to the next battery once the remaining chargeof the first battery is less than 5%.

A battery can be replaced without shutting down the OmniScan, as long as there isanother valid power source (DC power adapter or another battery).

3.2.2 Battery Status IndicatorsThe battery status indicators on the upper-left corner of the display screen indicate theamount of power left in each battery in one of the two following different ways (seeFigure 3-1).

The remaining operational time is displayed inside the battery status indicator.The OmniScan requires around 15 minutes of operation to display thisinformation.

The charge indicator (bar) inside the battery status indicator represents anapproximation of the amount of power left in that battery.

Figure 3-1 Battery charge status: charges remaining in both batteries18 Chapter 3

The battery that is currently being used is highlighted.The OmniScan software is designed to keep the user notified about the status of thebatteries. The battery status indicator variations are described in Table 2.

To charge the OmniScan batteries

Connect the OmniScan to a DC power adapter.

When the OmniScan is connected to a DC power adapter, it will automaticallyrecharge any battery that has less than 85% of its charge remaining. Each batteryrequires 3.5 hours to completely recharge.

3.3 Peripheral Connection

R/D Tech recommends to shut down the OmniScan before installing a peripheral,unless it is a USB peripheral, in which case a shutdown is not necessary.

3.4 Acquisition Module Replacement

The OmniScan is a modular device. The bottom part of the unit, the acquisitionmodule, can be swapped with another module with different technical characteristics.

CAUTION: Do not remove an acquisition module while the OmniScan is turnedon, because this can damage the internal circuits and will cause the loss of anyunsaved data. Always make sure to shut down the OmniScan before removing anacquisition module.

To replace an acquisition module

1 Turn off the OmniScan.20 Chapter 3

2 Remove all present batteries and disconnect the DC adapter if it is present.3 Flip the instrument face down.4 Unscrew the two captive screws either by hand or using a flat-head screwdriver.

When the two captive screws have been sufficiently loosened, they will pop outon their own because of a small metal spring.

CAUTION: Do not try to remove the captive screws entirely, as they are notdesigned to do so. Trying to remove them will result in material damage.

5 Using the two module extractors (the two plastic levers located on the oppositeside of the captive screws), loosen the module.

6 Remove the old module.7 Align the connector of the new module on top of the OmniScan connector, and

then gently press down.

8 Secure the new module by snapping the extractors back on the module.9 Screw in the two captive screws either by hand or using a flat-head screwdriver.10 Put the batteries back in the battery compartment or plug the DC power adapter.

To change the content of the primary information fields

1 Go to Reading > Result, and then choose the desired Field n option button.2 Choose the option you wish to display from the list.

4.1.3 Menu ButtonThe menu button contains all the main menus available in the current softwarepackage. Some of these menuslike File, Reading, User, and Utilitiescan be foundin every software package, while others are package-specific.

The main menus represent the first-level commands. When you select a menu fromthat list, its submenus and options appear automatically in their respective areas.

The menu button is displayed above the submenu buttons (see section 4.1.4). Thename on the menu button displays which menu is currently selected. Each menucontains between two and five submenus, which are displayed directly beneath it.

4.1.4 Submenu ButtonsThe submenu buttons are also found on the left side of the interface display, justbelow the menu button. They contain second-level commands. Between three and fivesubmenus are displayed whenever a menu is selected. The content of the submenusdepend on the menu that is selected.

When you select a submenu, the options associated to that submenu appear in theoption area at the bottom of the screen.

To select a submenu

1 Select a menu by using one of the navigation methods described in sections 4.2.1through 4.2.6.

2 Select the desired submenu button at the left of the data display area.If applicable, this will transfer you to the option area.OmniScan Interface 25

4.1.5 Option Buttons

The option buttons are located at the bottom of the interface display and they containthird- and fourth-level commands. There can be up to six option buttons persubmenu.

There are six types of buttons in the option area:

Command This type of button causes a specific action to be carried out(see Figure 4-2).

Figure 4-2 Example of a command button

Toggle This type of button allows you to alternate between twosettings (see Figure 4-3).

Figure 4-3 Example of a toggle button

List This type of button displays a list of options from which youmust choose (see Figure 4-4).26 Chapter 4

Figure 4-4 Example of a list button

Edit This type of button allows you to enter an alphanumericalvalue or modify an existing value (see Figure 4-5).

Figure 4-5 Example of an edit button

Edit list This type of button is similar to a list button, but possesses aneditable field as the last option in the list. This means thatyou can either choose one of the present options or createyour own (see Figure 4-6).OmniScan Interface 27

Figure 4-6 Example of an edit list button

Edit/cyclic This type of button contains two different values that can beedited separately (see Figure 4-7).a) The top section contains a numerical value that can be

modified in the same way as an edit button value.b) The bottom section allows you to cycle between a set of

fixed values by using one of the following methods: Click the section with a mouse repeatedly. Press the corresponding option key repeatedly. Using an external keyboard, press the corresponding

F key repeatedly.

Note: The principle behind the delta variable () is explained in detail underDelta variable, later in this section.

Figure 4-7 Example of an edit/cyclic button

Options can define a variety of settings. In the case of edit, edit list, and edit/cyclicbuttons, the contents can be modified using an external USB keyboard, theOmniScans function keys, or the scroll knob. Some options occasionally lead todeeper option levels.28 Chapter 4

Delta variableEdit/cyclic buttons contain a delta variable () in the lower part of the button (seeFigure 4-7). This variable specifies the increment that is used when you increase ordecrease the value in the upper box with the scroll knob.

For example, if the delta value of an option box is 6, then the value in the upper boxwill increase or decrease by 6-unit increments when you use the scroll knob. If youchange the delta value, the increment will change to match it.

To change the delta variable, press the option key ( ) located below the desiredoption, or click the delta variable with the mouse pointer. The variable will thencontinuously cycle among a set of available values.

5. Maintenance

This chapter deals with the basic maintenance that an operator can apply to theOmniScan MX unit. The maintenance operations explained below allow you tokeep the instrument in good physical and working conditions. Due to its design, theOmniScan requires only a minimum of maintenance. The chapter covers preventivemaintenance and instrument cleaning.

5.1 Preventive Maintenance

As the OmniScan does not have many moving parts, it does not require muchpreventive maintenance. Only a regular inspection of the instrument is recommendedto make sure that the OmniScan functions correctly.

5.2 Instrument Cleaning

The OmniScan external surfaces, that is, the casing, the acquisition module, and theLCD screen protector, can be cleaned when needed. This section provides theprocedure for the appropriate cleaning of the instrument.

5.2.1 Casing and Acquisition Module

To clean the casing and the acquisition module

1 MAKE SURE THE INSTRUMENT IS TURNED OFF, THAT THE POWER CORD ISDISCONNECTED, AND THAT THE BATTERIES HAVE BEEN PULLED OUT.

2 Disconnect all cables and connectors and make sure that all external ports on theOmniScan have been covered with their rubber protectors.Maintenance 39

3 Verify that the battery compartment door is closed correctly and that anacquisition module has been installed on the OmniScan.

4 To bring the instrument back to its original finish, clean the casing and themodule with a soft cloth.

5 To get rid of persistent stains, use a damp cloth with a soft soapy solution. Do notuse abrasive products or powerful solvents that might damage the finish.

6 When removing the connector protectors, check to make sure that the connectoritself is dry before connecting anything. If they are not dry, either dry them offusing a dry cloth or wait until they dry on their own.

5.2.2 LCD Screen Protector CleaningNever use abrasive products, or powerful solvents to clean the screen of theOmniScan. To clean the screen, use a damp cloth with a car windshield washer fluid.If you do not have a windshield washer fluid, you can use a common glass cleanerthat completely evaporates. If necessary, clear off paper towel residues using a soft-bristle brush.40 Chapter 5

6. Troubleshooting

This chapter will help you solve small problems that could occur during the operationof your OmniScan MX unit. This troubleshooting guide was written assuming thatthe instrument has not been modified and that the cables and connectors are thoseprovided and documented by R/D Tech.

The following topics are each addressed in detail afterwards in a specific section.

Startup Problems Error Messages Battery Charging Problems Battery Life Problems Memory Card Problems Microphone Problems Headphone or Speaker Problems Video Input Problems Video Output Problems Networking Problems USB Peripheral Problems Boot ProblemsTroubleshooting 41

6.1 Startup Problems

The OmniScan does not start up.

Possible solutions:

Check that the DC power adapter is connected to both the OmniScan and a poweroutlet with the proper voltage. Use only the adapter sold with the OmniScan.

Make sure that there is at least one battery charged up to 10% correctly inserted inthe battery compartment.

Press the power button for more than three seconds.

6.2 Error Messages

Error messages appear during the startup sequence.

6.3 Battery Charging Problems

The batteries do not charge when they are placed in the OmniScan.

Possible solutions:

Make sure that the battery model used in the OmniScan is compatible with thesuggested model. An incompatible battery may be able to power the unit, but therecharge protocol may not recognize it.

Make sure that the DC power adapter is correctly connected. Charge the batteries by using an external charger. Batteries charge much more

quickly when the OmniScan is not in use. Oppositely, the batteries will chargevery slowly, if at all, if the power consumption is too great.

Error message Solution

No module found Make sure that you have an acquisition module correctly attached to the base unit.

Error downloading code Restart the OmniScan.

Make sure that the software is up-to-date.42 Chapter 6

Shut the OmniScan down and wait for it to cool off. The internal charger is

equipped with a temperature monitor which prevents the recharge of batterieswhen the internal temperature is too high.

6.4 Battery Life Problems

The batteries no longer last as long as they used to.

Possible solutions:

Drain the batteries completely before recharging them. This will extend thelifespan of your batteries.

Calibrate the batteries using an external battery charger once a month. Thoughthe Li-ion batteries do not suffer from the common memory effect, calibratethem for optimum efficiency.

Verify your current configuration. There may be an option or a combination ofoptions that is draining the batteries too quickly. Such options include thebacklight, the voltage level, the acquisition rate, etc.

6.5 Memory Card Problems

There are problems in reading a file from the memory card or writing a file to thememory card.

Possible solutions:

Check to make sure that the memory card was inserted the right way in its slot.

CAUTION: The memory card slot of the OmniScan can be damaged if you forcethe insertion of a memory card the wrong way.

If the memory card was pulled out while the OmniScan was active, especially ifdata was being read or written, it might have caused data corruption.Troubleshooting 43

CAUTION: There is a small possibility that removing the memory card while theOmniScan is active could cause problems, especially if the memory card is beingaccessed or written to at the time of removal. These problems can range from asoftware crash to data loss or even memory card corruption.

Make sure that there is enough leftover space on the memory card to store thedata you are trying to save. R/D Tech offers memory cards with various storagecapacities. You may need a memory card with a bigger storage capacity.

Check your memory card to make sure it is correctly formatted. In most cases, anewly bought card is not formatted. You need a PC and a CompactFlashmemory card reader (USB or PCMCIA) to format a memory card in FAT32format.

Make sure that your data is not corrupted. Several factors can cause datacorruption. The most common factors are unfinished written data files,electrostatic discharges, and pulling the memory card out of the OmniScan whileit is active. Often, the only way to fix the problem is to erase the problem file orfiles, or to reformat the memory card.

CAUTION: Back up your files before you reformat a memory card. Reformattinga memory card causes the loss of all data on that card.

6.6 Microphone Problems

6.6.1 Internal MicrophoneThe internal microphone does not work.

6.6.2 External Microphone

The external microphone does not work.

Possible solution:

Make sure that the external microphone is plugged in the microphone jack.

6.7 Headphone or Speaker Problems

6.7.1 Internal SpeakerThe internal speaker does not work.

Possible solution:

Make sure that no headphones nor external speakers are plugged in theheadphone jack. This disables the internal speaker.

6.7.2 Headphones or External SpeakersThe headphones or external speakers do not work.

Possible solution:

Make sure that the headphones or external speakers are plugged in theheadphone jack.

6.8 Video Input Problems

The video input does not function.

Possible solutions:

Make sure that the video input option is available, as it can be bought separately. Make sure that the video cable is connected correctly.Troubleshooting 45

6.9 Video Output Problems

The video output does not function.

Possible solutions:

Make sure that the video output option is available, as it can be bought separately. Make sure that the video cable is connected correctly. Make sure that the external video monitor can sustain a resolution of 800 600 in

VGA mode. Make sure that your monitor respects the VGA standard. The VGA standard

requires the removal of pin 9 on the video connector. While the OmniScanrespects this specification, some monitors do not. If pin 9 is not removed on yourmonitor connector, you will have to remove it yourself. R/D Tech is notresponsible for any potential damage caused by this pin removal procedure.

6.10 Networking Problems

Ethernet communication is unavailable.

Possible solutions:

Make sure that the Ethernet option is available, as it can be bought separately. Make sure that the Ethernet cable is connected correctly. Make sure that you have installed the software that is necessary for the PC to

communicate with the OmniScan.

6.11 USB Peripheral Problems

Some USB peripherals do not function when connected to the OmniScan.

Possible solutions:

Use only a standard USB mouse. Use only a standard USB keyboard. Use only external storage devices that adhere to the USB Mass Storage

specification.46 Chapter 6

If it is a malfunctioning printer, make sure that it is compatible with the

OmniScan.

6.12 Boot Problems

6.12.1 A-Scan DisplayThe OmniScan software starts, but no A-scan is displayed.

Possible cause:

The BIOS version used is probably greater than 1.04B, but the fix for the old BIOScommand BIOS 1.04 Rev B.cmd has been executed.

Solution 1:

Correct the BIOS version by proceeding as follows:

1 Insert a CompactFlash memory card (with valid OmniScan software on it)in a memory card reader connected to a computer.

2 On the memory card, search for a directory named Run the Fix for old BIOS.3 Run the program Undo Fix.cmd.

This removes incompatible files.

4 Insert the memory card into the OmniScan, and then start the OmniScanusing the usual startup procedure.

Solution 2:

Correct the BIOS version by proceeding as follows: Delete the contents of the memory card, and then copy a clean version of the

software onto it without running the BIOS 1.04 Rev B.cmd command.

6.12.2 OmniScan StartupThe OmniScan logo is displayed with the BIOS version and an exclamation point (!),and the OmniScan does not start.

Possible cause:

A CompactFlash memory card that contains files necessary for the old BIOS versionTroubleshooting 47

has been used in the OmniScan, and the BIOS is in monitor mode.Solution:

Update the BIOS version by proceeding as follows:

1 Insert a CompactFlash memory card (with valid OmniScan software on it) ina memory card reader connected to a computer.

2 On the memory card, search for a directory named Run the Fix for old BIOS.3 Run the program Reset CMOS.cmd to create the necessary files on the

memory card.

4 Boot the OmniScan with the memory card. You should see the exclamationpoint (!) displayed and nothing else happening.This operation resets the CMOS parameters.

5 Take the memory card out of the OmniScan and reinsert it in the reader.6 Search for a directory named Run the Fix for old BIOS.7 Run the program Undo Reset CMOS.cmd to remove unnecessary files on the

memory card.

8 Boot the OmniScan with the memory card.It should now boot normally.48 Chapter 6
