Getting Started
Channel Up/Down Buttons
Your radio will Receive (Rx) and Transmit (Tx) 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 Channel Up
button will advance to Channel 01. If you are on Channel
01, pressing the Channel Down button will advance to
Channel 88.
You can press and hold the Channel Up/Down button
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.
