Using Your Radio

Boosting the Transmission Power

In most situations, 0.5W (UHF) and 1W (VHF) 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, for VHF, from 1W or 2.5W to 5W. For UHF, you can transmit
power from 0.5W or 1.5W to 2.5W.
Alkaline battery boost is limited to low and mid level in both
UHF and VHF modes.
Some Channels are 1W only and do not have power
NOTE
override capability. See channel list starting on page 33 for
a list of power-restricted channels.
1. Select the UHF/VHF mode and then the channel you want to transmit
on.
2. Press and hold ENT L/M/H button to switch to the next transmission
power level (for example, for VHF, from 5W to 2.5W; from 2.5W to 1W,
or from 1W back to 5W).
3. The display shows the new transmission power. The transmit power
remains at the new setting until you change it again.
Some channels limit the transmission power to 1W. When you tune to a
limited power channel, the radio automatically switches to 1W.
See the channel list starting on page 33 for a list of power-restricted
channels.
