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
x
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
x
mouth.
See page E-23 for a list of receive-only channels.

Changing the transmission level
In most situations, 1W 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 increase the
transmission power. If your radio is powered by a Li-Ion battery, you can press and hold the
BOOST button to transmit at 6W; however, NiMH battery power boost is limited to 1.5W.
To increase the transmission power in increments:
1.
Select the channel you want to transmit on.
2.
Press and hold DISP/ENT H/M/L to switch to the next transmission power level (for
example, from 1W to 2.5W, from 2.5W to 6W, or from 6W back to 1W).

The display shows the new transmission power as 6W, MID, or LOW. The transmit
power remains at the new setting until you change it again.
note: Don't forget to change the transmission setting back to 1W when you move close to
#
other stations.
Some channels (for example, channels 13 and 67) limit the transmission power to 1W.
When you tune to a limited-power channel, the radio automatically switches to 1W. See
page E-33 for a list of power-restricted channels.
