5. SQUELCH CONTROL: This knob is used to eliminate background noise

being heard through the receiver, which can be disturbing when no

transmissions are being heard through the receiver. To use this feature, turn the

knob fully counterclockwise and then turn clockwise slowly until the

background noise is just eliminated. Further clockwise rotation will increase

the threshold level that a signal must overcome in order to be heard. Only

strong signals will be heard at a maximum clockwise setting.

6. MIC GAIN CONTROL/PUSH TB OFF SWITCH: Adjusts the microphone

gain in 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. Pushing this

knob turns the Talkback circuit on and off.

7. RF GAIN CONTROL:

8. DIM CONTROL/PUSH FREQUENCY DISPLAY OFF SWITCH: This

knob controls the level of brightness for the meter lamp, faceplate, frequency

display and channel display. Pushing this knob turns the Frequency Display on

and off

9. RF POWER CONTROL: This control allows the user to adjust RF power

output.

10. COARSE/FINE CONTROL/PUSH NB-ANL OFF SWITCH:

variation of the radio operating frequencies above and below the channel

frequency. Although this control is intended primarily to tune in SSB signals,

it may be used to optimize AM/FM signals. Pushing this knob turns the Noise

Blanker (NB) / Automatic Noise Limiter (ANL) circuit on and off. The Noise

Blanker (NB) is very effective in eliminating repetitive impulse noise such as

ignition interference.

11. RX/TX/OFF/RX SWITCH: When in the RX/TX position, the two clarifiers

(Coarse and Fine) function on both receive and transmit. When the switch is in

the RX position, the Fine clarifier functions on receive only and the Coarse

clarifier still functions on both receive and transmit. When in the OFF position,

both clarifiers have no effect on the frequency.

12. CHANNEL SELECTOR: This control is used to select the desired transmit

and receive channel.

13. TB LED: This LED lights green when the TB function is on.

Adjust this knob for desired level of incoming signal.
