4.  RF GAIN CONTROL (outer dual concentric). 

Use to reduce the gain of the 

receive under strong signal conditions. 

 
5.  MODE (PA/FM/AM) SWITCH. 

This switch is used to select PA, FM, AM 

mode of operation. 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, 4-watt) to the PA Speaker jack on the unit rear 
panel.

 

 
6.  BAND SELECTOR. 

This switch is used to select the band.

 

 
7.  ECHO.

 This control is used to echo effect.

 This control is used to intervals of echo sound.

 

 
9.  CHANNEL SELECTOR.

 This switch selects any one of the forty channels 

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

 

 
10.  METER.

 This meter indicates received signal strength, transmitter RF output 

power.

 

 
11.  RF POWER.

 This switch is used to select transmitting power. In the HI 

position, the transceiver operates at 10 watts RF output power. In the MED 
position, the transceiver operates 5 watts RF output power. In the LO position, 
the transceiver operates in 2 watts RF output power.

 

 
12.  OFF/ANL/NB.

 When the switch is placed in the ANL+NB position, the RF 

Noise Blanker is also activated.  The RF Noise Blanker is very effective for 
repetitive impulse noise such as ignition interference.

 

 
13.  BAND SWITCH-HI/LOW. 

 This switch is used to select High band and or 

Low band Frequency Range. 

 

14.  OFF-ECHO SWITCH. 

This switch when set to ECHO position, will add an 

echo effect to your voice.

 

 
15.  RECIEVER/TRANSMIT INDICATOR. 

The receiver/transmit LED 

indicator is located next to the channel indicator. When in receive, the LED

Accepts 13.8V DC power cable with built-in fuse (10 amp.) to be 

connected. 

 
18.  EXT SP. 

Accepts 4 to 8 ohms, 5-watt external speaker to be connected. When 

external speaker is connected to this jack, the built-in speaker is automatically 
disconnected. 

 

19.  PA. SP.

 Used to connect a PA speaker (8 ohm 4W) for PA operation. Before
