Transmitting Power Level
You can select the transmitting power for all channels except
those designated as Receive Only or Low Power Channels
(see the Status column of the Frequency Charts for more
details).
Repeatedly press 1/2.5/5W. Each time you press the button,
the power output level changes and the corresponding icon
appears on the display.
Note: for those channels designated as 1W maximum, even
though you have set the power level to either 2.5 or 5W,
1W is displayed and used. Channels 13,17,67, and 77 in
the US are an exception. Normally these channels are also
designated for normal operation as 1W channels. However,
in emergency, if you press and hold the PTT switch and at
the same time you momentarily press 1/2.5/5W, the power
level changes from 1 to 5W with the Li-Ion battery or 1 to
2.5W with alkaline batteries installed.
You cannot override the 1W power level setting for
channels 75 and 76.
