This way, the transceiver is automatically turned off when theignition switch is turned off. Or, the power cord may be connected to an available terminal on the fuseblock, o...

Dynamic Squelch Control automatically sets Squelch to the optimal level for stronger transmission and signal clarity. To scan for weaker signals,turn Dynamic Squelch Control off and perform the following steps: 4a. Turn SQUELCH fully clockwise so only strong signals can get through. 4b. Turn SQUELCH...

5. Adjust RF GAIN knob (small) to optimize reception in strong signalareas. 6. Adjust DELTA knob (small) to reduce or eliminate adjacentchannel interference. 7. Set meter switch to S/RF . 7 Weather Information Set SQUELCH only when the radio is not receivinga strong signal. To configure your CB radi...

SWR Meter : Measures SWR (standing wave ratio) of antenna. Use to check antenna system or to adjust your antenna to the proper length. 8 To Transmit Multi-Function Meter Perform a voltage Standing Wave Ratio ( SWR ) measurement prior to using the transmitter. A SWR ratio in excess of 2:1 may damage ...

RF Meter : Measures RF Output Power for transmitter. To use, position the meter switch at S/RF . Press microphone PTT switch to read transmitting power. S-Meter : Measures incoming signal strength. To use, position the meter switch at S/RF . The meter swings to indicate signal strength. i.e. S 3, S ...
