Your radio can transmit selectively at 1, 3 or 6 watts of
power. Cobra suggests you maintain the low power setting
for short-range communications. You will conserve battery
life and avoid overpowering nearby stations with a low power
setting signal. Use the high power setting for long-range
communications or when you do not receive a response to
a signal sent at 1 watt.
To Toggle Between H-M-L Power Modes:
Press the H-M-L Power button. The LCD will show
which mode is in effect. Some channels are restricted
for a maximum use of 1 watt. Your radio will
automatically set the power to Low Power mode
when you select those channels.
NOTE
Some channels, frequency bands and countries of use
might not be able to operate in High Power mode.
NOTE
A few channels are Receive only and will not transmit
in these channels.
