(3) Select “3. Manual Adjustment” by pressing the  3 “R”  button

on the remote commander. The screen will appear as below.

(4) Select Iop by pressing  6 “R”  button on the remote commander.
(5) Wait until a hexadecimal number appear.

(6) Convert each data from hexadecimal to decimal using
      conversion table.

(7) Substract between these two values.

(8) If the remainder is smaller than 93 (decimal), then it is
      OK. However if the value is higher than 93, then the BU
      is defective and need to be change.

(9)  Press  ORETURN “R”  button to return back to previous

This adjustment is performed in order to adjust the transmission
distance of RF signal for DIAT communication.
Connection:

1. Connect the oscilloscope to TP815 and GND on the TX board.
2. Connect DIR-T1 to  DIR-T1  jack (I/O board: J602).
3. Adjust RV801 on the TX board so that the center of waveform

becomes 1.0 Vp-p.

4. Confirm trigger is locked.
5. Adjust RV801 on the TX board so that the center of waveform

becomes 2.2 to 2.4 Vp-p.

1. Conect an oscilloscope to CN105 pin 6 (RFMON) and CN105

pin 3 (GND) on the DMB10 board.

2. Turn the power on.
3. Insert the CD test disc (refer to the TEST DISC LIST), and

press the  H  button to play the disc back.

4. Confirm that oscilloscope waveform is clear and check RF

signal level is correct or not.

A clear RF signal waveform means that the shape “

clearly distinguished at the center of the waveform.

5. Eject the CD disc, and insert the DVD SL test disk (refer to the
