5.  DIMMER (inner dual concentric). 

Turns on/off the frequency display, 

channel number and the meter lamp. Switch on at minimum brightness 
and rotate clockwise for brighter illumination.

 

 
6.  RF POWER (outer dual concentric). 

This switch is used to select 

transmitting power.

 

 
7.  BAND SELECTOR.

 This switch selects A, B, C, D, E or F band of 

operation.

 

 
8.  CLARIFIER.

 Allows variation of the receiver operating frequencies 

above and below the as signed frequency. It may be used to optimize 
AM/FM signals as described in the Operating Procedure paragraphs, 
operates both TX/RX.

 

 
9.  CHANNEL SELECTOR.

 This switch selects any one of the forty 

channels desired. The selected channel appears on the LED readout 
directly above the Channel Selector knob.

 

 
10.  METER.

 This meter indicates received signal strength, and transmitter 

RF output power.

 

 
11.  MODE (FM/AM/PA) SWITCH.

 This switch is used to select PA, FM, 

AM mode of operation. The AM or FM mode is normally selected but 
when you set to PA position, the transceiver acts as a public address 
amplifier. Before operating PA, you must first connect an external PA 
speaker (8 ohm, more than 2W) to the PA Speaker jack on the unit rear 
panel.

 

 
12.  F. DISPLAY OFF/NB/OFF SWITCH.

 When the switch is placed in 

the NB position, the RF noise blanker is activated. The RF noise blanker 
is very effective for repetitive impulse noise such as ignition 
interference. If you wish to turn off the frequency display only set switch 
to NB+ position.

 

 
13.  ROGER BEEP SWITCH. 

 When this switch is placed in the ROGER 

BEEP position, your radio automatically transmits the audio sign at the 
end of your transmission. The listener can note easily your transmission 
is over through the sign. 

 

14.  +10KHz FREQUENCY SHIFT SWITCH. 

When switch is pressed the 

frequency is shifted 10KHz up. On following channels. A channel can
