Adjusts the microphone gain in the transmit and PA modes. 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.

4. RF GAIN CONTROL

This control is used to reduce the gain of the RF amplifier under strong signal conditions.

5. MODE SWITCH

This control allows you to select one of the following operating modes: PA/FM/AM.

In the PA position, the radio acts as a public address amplifier. Your voice will come out of the speaker that is plugged into the PA. SP. jack on the rear panel. The radio does not operate when you are in the PA mode. In the FM/AM position, the PA function is disabled and the unit will transmit and receive on the speaker that is connected to the radio.

6. FR. POOL SELECTOR

This switch is used to select the frequency range of operation (1 - 6).

7. ECHO SWITCH

This control is used for echo effect.

8. TIME CONTROL

This time control is used to control the intervals of the echo sound.

9. TALKBACK CONTROL

Adjust this knob for desired volume of Talkback. This is used to monitor your own voice. For example, you could use this feature to compare different microphones.

10. RF POWER CONTROL

This control allows the user to adjust RF power output.

11. CHANNEL SELECTOR

This control is used to select a desired transmit and receive channel.

12. FRONT PANEL METER

The Front Panel Meter allows the user to monitor signal strength, RF output power and SWR level.

13. TX/RX LED

The red LED indicates the unit is in the transmit mode. The green LED indicates the unit is in the receive mode.

14. FREQUENCY COUNTER

This display indicates the frequency of operation.

15. DIM/BRT SWITCH

This switch controls the level of brightness for the meter lamp, frequency display and the channel display. Press this switch (DIM) for the meter lamp, frequency display and the channel display to be dimly lighted. Depress this switch (BRT) for brighter effects.

16. HI/LO SWITCH

This switch selects received audio tone quality. In LO position, bass is increased and in HI position, treble is increased.
