more than 2 seconds.
Initialization of the factory.
NOTE: Do not use this for the normal servicing.
PLAY/REC total hours are displayed on the FIP.
Refer to the "PREVENTIVE CHECKS AND SERVICE INTERVALS"
(CONFIRMATION OF USING HOURS).
Can be checked of the INITIAL DATA of MEMORY IC.
Refer to the "NOTE FOR THE REPLACING OF MEMORY IC".
Adjusting of the Tracking to the center position.
Refer to the "MECHANICAL ADJUSTMENT" (GUIDE ROLLER) and "ELECTRICAL
ADJUSTMENT" (PG SHIFTER).
Press the ATR button on the
remote control for more than
2 seconds during PLAY.
While pressing the CH UP
button on the set, press the
STOP button on the set for
more than 2 seconds during
PLAY.

the GND.
The EOT/BOT/Reel sensor do not work at this moment.
Refer to the "PREPARATION FOR SERVICING"
Adjust the PG SHIFTER automatically.
Refer to the "ELECTRICAL ADJUSTMENT" (PG SHIFTER).
While pressing the CH UP
key on the set, press the
FF key on the set for more
than 2 seconds.

PREVENTIVE CHECKS AND SERVICE INTERVALS
The following standard table depends on environmental conditions and usage. Unless maintenance is properly
carried out, the following service intervals may be quite shortened as harmful effects may be had on other parts.
Also, long term storage or misuse may cause transformation and aging of rubber parts.

5.
Turn on the POWER.
While pressing the CH UP button on the set, press the FF button on the set for more than 2 seconds.
Adjust the ADDRESS to "20" by SET +/- button and read the DATA.
(This DATA becomes the thousands digit and hundreds digit value of the following formula.)
Adjust the ADDRESS to "21" by SET +/- button and read the DATA.
(This DATA becomes the tens digit and ones digit value of the following formula.)
After the confirmation of using hours, turn off the power.

PREVENTIVE CHECKS AND SERVICE INTERVALS
CLEANING
NOTE
After cleaning the heads with isopropyl alcohol, do not
run a tape until the heads dry completely. If the heads
are not completely dry and alcohol gets on the tape,
damage may occur.
1. AUDIO CONTROL HEAD
Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol and clean the audio control head by
wiping it horizontally. Clean the full erase head in the
same manner. (Refer to the figure below.)
Audio Control Head
2. TAPE RUNNING SYSTEM
When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.
3. CYLINDER
Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol. Hold it to the cylinder head softly.
Turn the cylinder head counterclockwise to clean it (in
the direction of the arrow). (Refer to the figure below.)
NOTE
Do not exert force against the cylinder head. Do not move
the chamois upward or downward on the head.
Use the chamois one by one.

The unit will now have the correct DATA for the new MEMORY IC.
Fig. 1
ADDRESS is now selected and should "blink". Using the SET + or - keys on the remote, step through the ADDRESS until
required ADDRESS to be changed is reached.
Press ENTER to select DATA. When DATA is selected, it will "blink".
Again, step through the DATA using SET + or - until required DATA value has been selected.
Pressing ENTER will take you back to ADDRESS for further selection if necessary.
Repeat steps 3 to 6 until all data has been checked.
When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.
