Low Power
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to set
the radio's transmitter to the "Low Power" mode,
thus extending battery life. Press the assigned
Soft key again or switch the TOGGLE switch
to the other Position to return to "High Power"
operation when in difficult terrain.
Talk Around
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to ac-
tivate the Talk Around feature when you are op-
erating on duplex channel systems (separate re-
ceive and transmit frequencies, utilizing a "re-
peater" station). The Talk Around feature allows
you to bypass the repeater station and talk directly
to a station that is nearby. This feature has no ef-
fect when you are operating on "simplex" chan-
nels, where the receive and transmit frequencies
are already the same.
Note that your dealer may have made provision
for "Talk Around" channels by programming "re-
peater" and "Talk Around" frequencies on two
adjacent channels. If so, the key may be used for
one of the other Pre-Programmed Functions.

TX Save Disable
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to dis-
able the Transmit Battery Saver, if you are operat-
ing in a location where high power is almost al-
ways needed.
The Transmit Battery Saver helps extend battery
life by reducing transmit power when a very
strong signal from an apparently nearby station
is being received. Under some circumstances,
though, your hand-held radio may not be heard
well at the other end of the communication path,
and high power may be necessary at all times.
LCD Invert
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to in-
vert the LCD display to backward-facing readout
(the backward display is convenient for viewing
when wearing the transceiver on your belt). Press
the assigned Soft key again or switch the
TOGGLE switch to the other position to return
the LCD display to frontward-facing readout.
