Details

Bend this part to adjust the height of the STB holder.

Adjusting procedure

1. Turn the mode big gear approx. 37 degrees in the arrow direction.
2. Viewing from the front side of the mechanism, verify that the guide ribs
     (CHANGE BOX L/R and STB HOLDER) of tray are as tall as each other.
3. If they are not, bend the lever for adjustment. (Refer to the details.)
Note: Also apply the same adjustment on the R side.

First, remove the mechanism unit section from the set, and check for the state of the disc.
(Remove the top plate R if necessary.)
<State of the disc>
(1) When the disc is in the normal PLAY (chucking) position -> Try to eject the disc by turning the mode big gear/tray big gear

manually.

                                                                                                   * At this time, be sure to adjust the tray's position (height).
(2) When the disc is in the normal STOCK position -> Try to eject the disc by turning the tray big gear manually.
                                                                                   * At this time, be sure to adjust the tray's position (height).
(3) When the disc is not in the normal position -> The tray or disc is not in the normal position. (The tray or disc may catch

somewhere.)

Remove the TOP PLATE F/DISC OB lever.
Unlock the tray lock lever and pull out the tray which is not caught.
Move the caught tray or disc and remove the disc.

In case of (1) and (2), the mechanism is normal (defective circuit parts, etc.). However, it may stop somewhere.
This is the reason why you should try to turn the tray big gear first.
In case of (3), either of the big gears does not turn.

Notes:
1: Description of the "FM IF Adjustment" is not carried on this

Manual. It is because the IF coil in the FM front end section
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.

2: The parts in the FM front end section are prepared in a

complete unit, so you can't obtain each part individually.

the specified test mode. This operation is applied to the main unit's keys only.

In the destination display, a destination code (H/W/U/J) is displayed. For the span display, "9" means 9 kHz/50 kHz, and "10"
means 10/100 kHz. All pictures will disappear except the characters.
