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. Transmitter
2-1-1. Oscillating frequency adjustment
Method:
1. Supply 9 V to the DC jack (J1) from a stabilized power supply.
2. Perform this adjustment without signal.
3. Connect a frequency counter between TP17 (RF) and TP18
(GND).
4. Adjust L1 so that the reading on the counter is 2,300 kHz.
Specified V alue:
Frequency counter
2,295 to 2,305 kHz
5. Connect an oscilloscope between TP17 (RF) and TP18 (GND).
6. V erify that the Vp-p v alue of the wav eform on the oscilloscope is
1.2 V or more.
