To adjust the unit, operate the unit by itself using the conduction jig
(PFJ-1).

For details on switching functions and fast forwarding the unit, etc.
when operating it by itself, refer to “Connection and Operations of
the Unit by Itself” on page 5 of Servicing Notes.

• Turning on the power
When operating the unit by itself:
1. After turning ON the power of the conduction tool (PFJ-1), press

the  π (TAPE A)  button,  π (TAPE B)  button, and  · (TAPE
B)  button together in this order.

Inputting/outputting audio signals:
Use the jack of the power supply jig (PFJ-1).

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 adjust-
ment.)

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.

Note: Set the test mode using the following method and begin tape

speed adjustment.
In the test mode, the speed will switch to double speed or
normal speed each time the  HI-DUB  button is pressed.

Procedure:
Press the  p (CD)  button while pressing the  DIRECTION MODE
button.

1. Insert the WS-48B into deck B, while pressing the  p (CD)

button, press the  ª (TAPE A)  button, set the function to “deck
B”.

2. Press the    ·  button of deck B.
3. Press the  HI-DUB  button and play the tape at double speed.
4. Adjust RV1001 of the LEAF SW board so that the reading of

the frequency counter becomes 6000 ± 180 Hz.

5. Press the  HI-DUB  button and play the tape at normal speed.
6. Adjust RV1002 of the LEAF SW board so that the reading of

the frequency counter becomes 3000 ± 90 Hz.
