VHF signals on
the channel indicated on the LCD display. You can change the
channel at any time using the
Channel Up/Down
buttons.
To Change Channels:
Press the
Channel Up/Down
button.
If you are on Channel 88, pressing the

button will advance to Channel 01. If you are on Channel
01, pressing the

for fast advance. If the new channel selected is restricted
to low power, the radio will automatically switch to
Low
Power
mode and the
Low Power
icon will appear on the
LCD.
If the radio is in the
Key Lock
mode, the channel will not
change and the three (3) beep error signal will sound.
High/Medium/Low (H/M/L) Power Selection
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
MORE
soft key until the screen shows as illustrated.
Pres the
H-M-L
soft key to set the power 1W, 3W, or 6W.
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.
