Operating Your Radio

Voice Transmission

Transmit Power Output

HI/LO Power Button

Standby Low Power Mode

Standby High Power Mode

The radio transmits selectively at 1 or 25 watts of power. Cobra suggests maintaining the low power setting for short- range communications to avoid overpowering nearby stations with the signal. Use the high power setting for long-range communications or when no response is received from a signal sent at 1 watt.

To Toggle Between the High and Low Power Modes:

Press the HI/LO Power button.

The LCD displays which mode is selected.

Some channels are restricted to be used at a maximum of 1 watt. The radio automatically sets the power to Low Power mode when a restricted channel is selected.

While using the U.S.A. channel map, if, in an emergency, it is necessary to increase the output power on Channel 13 and Channel 67 for the signal to be heard, override the Low Power mode by pressing and holding the HI/LO Power button.
