3.1 CONTROL AND CONNECTIONS

3.1.1 FRONT PANEL

Refer to the above Figure 3-1 for the location of the following controls.
1. POWER ON/OFF SWITCH
Push this switch to apply power to the unit.
2. CALIBRATE CONTROL
This control is used for calibrating the built in SWR meter for accurate SWR readout. Control should
normally be left in the fully counter clockwise position for accurate power output meter readings. (This
stop is marked "RF")
3. RF POWER CONTROL
This control allows the user to adjust RF power output.
4. RF GAIN CONTROL
This control is used to reduce the gain of the RF amplifier under strong signal conditions.
5. MIC GAIN CONTROL
Adjusts the microphone gain in the transmit and PA mode. This controls the gain to the extent that full
talk power is available several inches away from the microphone. In the Public Address (PA) mode, the
control functions as the volume control.
6. CHANNEL SELECTOR
This control is used to select a desired transmit and receive channel.
7. CLARIFIER CONTROL
Allows adjustment of the receive frequency above or below the channel frequency. Although this
control is intended primarily to tune in SSB signals, it may be used to optimize AM/FM signals as well.
8. SQUELCH CONTROL
This switch is used to eliminate background noise being heard through the receiver which can be
disturbing when no signal is being received. To use this feature of your radio, gently turn the switch
fully counterclockwise, and then turn clockwise until the background noise is just eliminated. Further
clockwise rotation will increase the threshold level so that only strong signals will be heard.
9. VOLUME CONTROL
Turn clockwise to set the desired listening level.
10. MODE SELECTOR
This selector allows you to select one of the following operating modes: FM/AM/USB/LSB/CW/PA.
