To Squelch Your Radio:
1. With the Squelch knob turned fully counter-clockwise, turn
the On-Off/Volume knob clockwise until you hear
a hissing (noise) sound.
2. Turn the Squelch knob clockwise until the hissing
sound stops.
Turning the Squelch knob further clockwise (higher barrier)
will filter weak and medium strength signals until only the
strongest signal can get through at the highest squelch setting.
The Squelch bar graph will be shown to indicate the Squelch
setting. 2 seconds after finishing the Squelch adjustment, the
radio will return to the
Standby mode.
To Receive Weaker Signals:
1. Turn the Squelch knob counterclockwise (lower barrier).
If the squelch is set so that you can hear a continuous hissing
sound, the memory scan and dual watch functions will be
blocked.

Transmit Power Output
Your radio can Transmit selectively at one (1) or 25 watts of power. Cobra
®
suggests
you maintain the low power setting for short-range communications and to avoid
overpowering nearby stations with your signal. Use the high power setting for long-range
communications or when you do not receive a response to a signal sent at one (1) watt.
To Toggle Between The High And Low Power Modes:
1. Press the High/Low Power button. The LCD will show which
mode is in effect.
Some channels are restricted to use at a maximum of one
(1) watt. Your radio will automatically set the power to Low
Power mode when you select those channels.
While using the U.S.A. channel map, if, in an emergency,
you need to increase the output power on Channel 13 and
Channel 67 for your signal to be heard, you can override the
Low Power mode by pressing and holding the High/ Low
Power button.
Transmit a Message
1. Check to see that your unit is set to a proper channel for the
type of message you plan to send.
2. Toggle to the low power setting.
3. With the microphone about two (2) inches [five (5) cm] from
your mouth, press and hold the Talk button and speak into
the microphone. Transmit will be indicated on the LCD.
4. Release the Talk button when you are finished speaking. Your
unit can only operate in either the Transmit or the Receive
mode at any given time. You will not hear the response to your
message unless the
Talk button is released.
NOTE
If the Talk button is held down for five (5) minutes, the radio will
automatically cease transmitting to prevent unwanted signal generation.
As soon as the
Talk button is released, it can be pressed again to
resume transmission.
