SERVICING NOTICES ON CHECKING
As for the places which need special attentions,they are indicated with the labels or seals on thecabinet, chassis and parts. Make sure to keep theindications and notices in the operation manual.
PERFORM A SAFETY CHECK AFTERSERVICING
4.
Confirm that the screws, parts and wiring whichwere removed in order to service are put in theoriginal positions, or whether there are theportions which are deteriorated around theserviced places serviced or not. Check theinsulation between the antenna terminal orexternal metal and the AC cord plug blades.And be sure the safety of that.
2. USE THE DESIGNATED PARTS
The parts in this equipment have the specificcharacters of incombustibility and withstandvoltage for safety. Therefore, the part which isreplaced should be used the part which hasthe same character.Especially as to the important parts for safetywhich is indicated in the circuit diagram or thetable of parts as a mark, the designatedparts must be used.
1. KEEP THE NOTICES 3. PUT PARTS AND WIRES IN THEORIGINAL POSITION AFTERASSEMBLING OR WIRING
There are parts which use the insulationmaterial such as a tube or tape for safety, orwhich are assembled in the condition thatthese do not contact with the printed board.The inside wiring is designed not to get closerto the pyrogenic parts and high voltage parts.Therefore, put these parts in the originalpositions.
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)1. MODEL NUMBER and VERSION LETTER
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be found at the end of the SERIAL NUMBER.2. PART NO. and DESCRIPTION
You can find it in your SERVICE MANUAL.

NOTE
REMOVAL AND INSTALLATION OFFLAT PACKAGE IC
Some ICs on the PCB are affixed with glue, so becareful not to break or damage the foil of each ICleads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within10 mm distance from IC leads.

NOTE
Do not add the rotating and the back and forthdirections force on the IC, until IC can move back andforth easily after desoldering the IC leads completely.
When IC starts moving back and forth easily afterdesoldering completely, pickup the corner of the IC usinga tweezers and remove the IC by moving with the ICdesoldering machine. (Refer to Fig. 3-3.)

When the IC leads are bent during soldering and/orrepairing, do not repair the bending of leads. If thebending of leads are repaired, the pattern may bedamaged. So, be always sure to replace the IC in thiscase.
Finally, confirm the soldering status on four sides of theIC using a magnifying glass.Confirm that no abnormality is found on the solderingposition and installation position of the parts around theIC. If some abnormality is found, correct by resoldering.

SERVICE MODE LIST
This unit provided with the following SERVICE MODES so you can repair, examine and adjust easily.
Method Operations
Adjusting of the Tracking to the center position.Refer to the "MECHANICAL ADJUSTMENT" (GUIDE ROLLER) and "ELECTRICALADJUSTMENT" (PG SHIFTER).
Press the ATR button on theremote control for more than2 seconds during PLAY.
Make the short circuit betweenthe test point of SERVICE andthe GND.
The BOT, EOT, and the Reel Sensor do not work and the deck can be operatedwithout a cassette tape.Refer to the "PREPARATION FOR SERVICING"
C3-1
PREVENTIVE CHECKS AND SERVICE INTERVALS
The following standard table depends on environmental conditions and usage.Parts replacing time does not mean the life span for individual parts.Also, long term storage or misuse may cause transformation and aging of rubber parts.The following list means standard hours, so the checking hours depends on the conditions.
: Clean: Check it and if necessary, replace it.
CLEANINGNOTE
After cleaning the heads with isopropyl alcohol, do notrun a tape until the heads dry completely. If the headsare not completely dry and alcohol gets on the tape,damage may occur.
1. AUDIO CONTROL HEAD
Clean the Audio Control Head with the cotton sticksoaked by alcohol. Clean the full erase head in thesame manner. (Refer to the figure below.)
2. TAPE RUNNING SYSTEM
When cleaning the tape transport system, use thegauze moistened with isopropyl alcohol.
3. CYLINDER
Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol. Hold it to the cylinder head softly.Turn the cylinder head counterclockwise to clean it (inthe direction of the arrow). (Refer to the figure below.)
NOTE
Do not exert force against the cylinder head. Do not movethe chamois upward or downward on the head.Use the chamois one by one.
