Voice Transmission
Transmit Power Output
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.
