• Onlyuseattachments/accessoriesspecifiedbythemanufacturer.

• Useonlywith thecart,stand, tripod,bracket,or tablespecifiedbythemanufacturer,orsoldwith theapparatus.Whenacart isused,usecautionwhenmoving thecart/apparatus combination to avoid injury from tip-over.

• Unplugthisapparatusduringlightningstormsorwhenunusedforlongperiodsoftime.

• Referallservicingtoqualifiedservicepersonnel.Servicingisrequiredwhentheapparatushasbeendamagedin any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

When Installing the Unit

• Donotexpose theunit to rainor anenvironmentwhere it may be splashed by water or other liquids, asdoingsomayresultinfireorelectricshock.

• Use the unit only with the voltage specified ontheunit.Usingavoltagehigherthanthatwhichisspecifiedmayresultinfireorelectricshock.

• Do not cut, kink, otherwise damage nor modifythe power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing somay result in fire orelectric shock.

• Avoid installing or mounting the unit in unstablelocations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling downandcausingpersonal injuryand/orpropertydamage.

• Since the unit is designed for indoor use, do notinstall it outdoors. If installed outdoors, the aging of parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of electric shock.

When the Unit is in Use

• Should the following irregularity be found duringuse, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this maycausefireorelectricshock.

· If you detect smoke or a strange smell coming from the unit.· If water or any metallic object gets into the unit · If the unit falls, or the unit case breaks · Ifthepowersupplycordisdamaged(exposureofthecore,disconnection,etc.)

· Ifitismalfunctioning(notonesounds.)

• Topreventafireorelectricshock,neveropennorremove the unit case as there are high voltage components inside the unit. Refer all servicing to qualifiedservicepersonnel.

• Do not place cups, bowls, or other containers ofliquid or metallic objects on top of the unit. If they accidentallyspillintotheunit,thismaycauseafireor electric shock.

• Donotinsertnordropmetallicobjectsorflammablematerialsintheventilationslotsoftheunit'scoverasthismayresultinfireorelectricshock.

• Theapparatusshallbeconnectedtoamainsocketoutlet with a protective earthing connection.

• The socket-outlet shall be installed near theequipment and the plug shall be easily accessible.

When Installing the Unit

• Never plug in nor remove the power supply plugwith wet hands, as doing so may cause electric shock.

•Whenunplugging thepower supply cord, be sureto grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supplycordmaycauseafireorelectricshock.

2. SAFETY PRECAUTIONS• Before installationoruse,besure tocarefully readall the instructions in thissection forcorrectandsafe

operation.• Besuretofollowalltheprecautionaryinstructionsinthissection,whichcontainimportantwarningsand/or

·Whenconnectingtheunit'spowercordtoanACoutlet, use the AC outlet with current capacity allowable to the unit.

(EveryversionexcepttheDP-SP3CUforUS)· The supplied rack-mounting screws can be used

for the TOA equipment rack only. Do not use them for other racks.

(DP-SP3CUforUS)· Rack-mounting screws are not supplied with the

unit. Prepare them that are appropriate for the equipment rack.

· Be sure to complete installation and cableconnections before connecting the unit’s power plug to the power source. When uninstalling the unit or disconnecting the unit’s cables, be sure to disconnect the power plug from the power source first.Doingotherwisemayresultinelectricshock.

• LANConnectorcannotconnecttoConnectorwhichmight catch overvoltage.

When the Unit is in Use

• If dust accumulates on the power supply plug orin the wall AC outlet, a fire may result. Clean itperiodically. In addition, insert the plug in the wall outlet securely.

(Whenrackmountingscrewsaresupplied)The supplied rack-mounting screws can be used for the TOA equipment rack only. Do not use them for other racks. When installing the unit in a rack other than that of TOA, be sure to use the screws with a diameter of over5mm(0.2”)andlengthofover12mm(0.47”)tomount the unit.Failure to do so may cause the unit to fall, resulting in personal injury.

Wiring procedures

Step 1. Wiring the supplied removable terminal plug.

1-1. Loosen the terminal screws to insertthe wire.

1-2. Tighten the terminal screws.Ensure that the wire does not break free when pulled. If the wire does pull free, repeat the connection procedure from the start.

Step 2. Insert the wired terminal plug into the corresponding terminal block in the unit’s rear panel.

Note Do not reverse Steps 1 and 2 above. Force is applied to the connected receptacle pins while tightening the terminal screw and they may be damaged, resulting in bad connector contact.
