Pin layout on terminal board
2-4.
Envelope Waveform Output Method
The envelope waveform can be output by connecting the
output terminals on the CP1 circuit board to an
oscilloscope. To actually do this, connect a tape path
adjustment tool in between.
Connection method
(1 ) Clamp the clip of the tape path adjustment tool to
terminal J1 005 of the CP1 circuit board so that the
positioning holes are aligned .
(2) Connect the terminals of the tape path adjustment
tool to an oscilloscope. The terminals to be connected
at this time are as follows.
� : Switching pulse (RF SW1 )
�
: Envelope
(PB RF)
!! : Ground
(GND)
2-5.
PCM Range Output Method
After the envelope waveform has been output according
to the method outlined in 2-4., if the two terminals
indicated below of the tape path adjustment tool are
shorted, the head output will be fixed at channel B and
an envelope waveform which includes the PCM range of
channel B will be output.

3-2. Tracking Fine Adjustment
[OLD]
Note
1 :
Shift track amount adjustment method
Because of the settings, sometimes the waveform
amplitude will not be exactly at the 4th step in the shift
track mode. I n such cases, adjust the shift track amount
by the following method to align it exactly with the 4th
step.
•
If the amplitude is lower than 4, press
the REW
button
while pressing the START/STOP button to increase
the amplitude of the waveform.
•
If the amplitude is higher than 4, press
the
FF
button
while pressing the START/STOP button to decrease
the amplitude of the waveform.
Tape path adjustment should be carried out with this
envelope waveform which includes the PCM range.
However, in other cases, the PCM region will not be
output.

Setting the Test Mode
To set test mode, short the two terminals indicated below
of the tape path adjustment tool.

2-7.
Setting the Shift Track Mode
After setting the test mode by the method in 2-6 . , press
the START/STOP button on the PW1 circuit board once
to set the shift track mode. When this mode is set, only
the fixed amount of track shift will occur, and the result of
this will be that the amplitude of the envelope waveform
will become 2/3 that of the previous waveform.
If the P LAY button on the CP1 circuit board is pressed or
if test mode is canceled during the shift track mode, the
shift track mode will be canceled.
(Furthermore, the START/STOP and P LAY buttons on
the remote control can also be used.)
