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 (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
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 (2) inches [five (5) 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 (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.
