Procedure:

1. Press ?/1 button to turn the set ON.

2. Press VIDEO (MD) and ?/1 buttons simultaneously, and the

display of fluorescent indicator tube changes to “MD” or
“VIDEO”, and thus the channel step is changed over.

3. Press ?/1 button to turn the set OFF.

[GC Test Mode]

•This mode is used to check the FL tube, LED, keyboard, volume
and phones.

Procedure:

1. Press three buttons x , GAME EQ , and DISC 2 simulta-

neously.

2. LEDs and fluorescent indicator tube are all turned on.

3. Press simultaneously the two buttons of GAME EQ and DISC

2 . Whenever these two buttons are pressed simultaneously, the
mode changes from Key check, Key count check, Headphones
input check and Volume check in this order.

4. When the Key check mode is entered, the display shows the

indication of “KEY 0 0 0”.
The keys that are assigned to the respective channels of the key
entry signal lines (KEY0, KEY1, KEY2) that are input to IC701
Display Controller on the panel board, are checked. While you
press the button, the number that corresponds to the key shown
in the table below , is displayed in the location of the correspond­ing channel. (The ?/1 and DISPLA Y b uttons are not included
in these channels.)

demagnetizer.

2. Do not use a magnetized screwdriver for the adjustments.

3. After the adjustments, apply suitable locking compound to the

parts adjust.

4. The adjustments should be performed with the rated power sup-

ply voltage unless otherwise noted.

5. The adjustments should be performed in the order given in this

service manual. (As a general rule, playback circuit adjustment
should be completed before performing recording circuit adjust­ment.)

6. The adjustments should be performed for both L-CH and R-CH.

7. Switches and controls should be set as follows unless otherwise

specified.
