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 finished 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 find 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-2.5Wbutton 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-2.5Wbutton 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.
