ELECTRICAL ADJUSTMENTS

Note:

1. The adjustments is performed in the order that they are listed.

2. When adjusting the remote commander, the transmitter is used
for adjustment.

3. 0 dB=1.0 V

2-1. Remote commander

2-1-1. Tuning adjustment

Method:

1. Supply 6 V to TP1 (6 V) from a stabilized power supply.
(TP3 (GND) is connected to the ground.)

2. Input a signal of 1 kHz and –10 dB to the transmitter (TMR­IF10M) from an oscillator.

3. Connect a distortion factor meter between TP20 and TP21.
Note:The speaker should be always connected to protect the

circuit.

4. Set the volume (VR51) to the maximum position.

5. Adjust T51 so that the reading on the distortion factor
meter is minimum.
