Receiver Squelch Adjustment
1. Set the channel selector for the mid frequency receive channel.
2. Connect an RF signal generator or communications service monitor to the antenna receptacle. The
modulation should be set fot ±3 kHz FM modulation of a 1kHz tone. The RF output level should be at a
minimum.
3. Adjust the SQUELCH control to the threshold point (the point where the speaker audio disappears).
4. Increase the RF signal generator output level until speaker audio output reappears. Note the generator level.
5. Turn the SQUELCH control fully clockwise.
6. Increase the RF signal generator level by 16 dB.
• NOTE: This squelch adjustment procedure is very important for the correct operation of the microprocessor
aided squelch system.
