Making a transmission
Remove the radio from the charger, 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. If you talk for over 5 minutes
continuously, the display shows RELEASE PTT KEY.
For the best sound quality, hold the microphone about
two inches away from your mouth.
See the channel lists starting on page 28 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:
Select the channel you want to
transmit on
Press the
1/2.5/5W button to
switch to the next transmission
power level (for example, from 5
Watt to 2.5 Watts; from 2.5 Watts
to 1 Watt, or from 1 Watt back
around to 5 Watts).
The display shows the new
transmission power in the upper
left hand corner. The transmit
power remains at the new setting
until you change it again.
Note: Don’t forget to change the transmission setting
back to 1 Watt when you move close to other stations.
