Transmit Power Output
Your radio can Transmit selectively at 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 1
watt.
To Toggle Between The High And Low Power Modes:
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 watt. Your radio will automatically switch 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
To Transmit A Message:
1. Check to see that your unit is set to a proper
channel for the type of message being sent.
2. Toggle to the low power setting by pressing the
High/Low Power button.
3. With the microphone about two inches [five cm] from your
mouth, press and hold the Talk button and speak into the
microphone. TX (Transmit) displays on the LCD display.
4. Release the Talk button when you are finished speaking.
To hear a response, the Talk button must be released.
NOTE
If the Talk button is held down for five 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.
