6. SWR LED: This LED lights red when your SWR is higher than about 3:1. This is

not an exact indicator of 3:1 SWR, but it is an indication that you should check

your SWR reading.

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

receive channel.

8. FRONT PANEL METER: The front panel meter allows the user to monitor

incoming signal strength, RF output power, SWR level and AM modulation level.

9. RF GAIN CONTROL: This control is used to reduce the gain of the RF (receive)

amplifier under strong signal conditions.

10. DIMMER CONTROL: This knob controls the level of brightness for the meter

lamp and channel display.

11. SWR/MOD/PWR SWITCH: This switch controls the function of the meter

during the transmit mode. In the "SWR" position, the meter indicates the Standing

Wave Ratio (SWR) of your antenna. There are no adjustments because the SWR

circuit in this radio calibrates itself automatically. When the switch is in the

"MOD" position, the green scale on the meter indicates your percentage of

modulation in the AM mode only. They are most accurate when testing at

maximum power output. When this switch is in "PWR" position, the meter

indicates your power output.

12. NB-ANL/CB/PA SWITCH: When the switch is in the NB/ANL position, the

Noise Blanker (NB) and Automatic Noise Limiter (ANL) circuits are activated.

The Noise Blanker is very effective in eliminating repetitive impulse noise such

as ignition interference. In the CB position, the PA function is disabled and the

radio will transmit and receive on the speaker that is connected. In the PA position,

the radio acts as 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.

13. TALKBACK SWITCH: This feature is used to monitor your own voice. For

example, you could use this feature to compare different microphones. HI is high

volume. LO is low volume. The Talkback circuit is off when the switch is in the

OFF position.

14. RX/TX LED: This LED is green during receive and red during transmit.

15. CHANNEL DISPLAY: The channel display indicates the current selected

channel.

1. ANTENNA: This jack accepts a 50-ohm coaxial cable with a PL-259 type plug.

2. DC POWER: This jack accepts the 13.8V DC power cable with built-in fuse.

The power cord provided with the radio has a black and red wire. The black goes

to negative and red goes to positive.

3. PA SP: This jack is for PA operation. Before operating, you must first connect a

PA speaker (8 ohms, 4W) to this jack.

4. EXT. SP: This jack accepts a 4 to 8 ohm, 5-watt external speaker. When the

external speaker is connected to this jack, the built-in speaker will be disabled.

5. F.C.: This jack is used to connect the optional Galaxy FC347 six-digit frequency

counter. All connections, including DC power, are provided to the FC347 through

this jack.
