Making a transmission
Select the channel you want to transmit on, then press and
hold the Push to Talk button. Release the Push to Talk
button when you’re nished talking to let the other party
respond.
To prevent stuck microphone problems or situations where •
the Push to Talk button is pushed accidentally, the radio
limits your talk time to 5 minutes in a single transmission.
For the best sound quality, hold the microphone about two •
inches away from your mouth.
See the channel lists starting on page • 19 for a list of
receive-only channels.
Boosting the transmission power
In most situations, the 1 Watt transmission power is all you
need. If you nd yourself far away from other stations and
have trouble getting a response, you may need to boost the
transmission power from 1 Watt to 2.5 Watts or 5 Watts:
Press the • 1/5W-2.5W button to switch from 1 Watt to 5
Watts. Press the button again to switch back to 1 Watt.
To switch to 2.5 Watts, press and hold the • 1/5W-2.5W
button for about two seconds. Press and hold the button
again to switch back to 1 Watt or 5 Watts (whichever you
were on when you switched to 2.5 Watts).
The transmit power remains at the new setting until you •
change it again. The transmit power icon always shows the
current transmission power.
Note: Don’t forget to change the transmission setting
back to 1 Watt when you move close to other stations.
Some channels (for example, channels 13 and 67) limit •
the transmission power to 1 Watt. When you tune to a
limited-power channel, the radio automatically switches to
1 Watt. See the channel lists starting on page 19 for a list
of power-restricted channels.
