TX Save Off
Press the assigned Soft key or switch the Toggle switch to the assigned
position to disable the Transmit Battery Saver, if you are operating in a
location where high power is almost always 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
Pressing the assigned Soft key or switch the Toggle switch to the as-
signed position inverts 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-return the LCD display to frontward-facing
readout.
Encryption Off
Press the assigned Soft key or switch the Toggle switch to the assigned
position to turn off the optional voice encryption unit temporarily, for use
when an incorrect setting of (or failure in) the encryption system at one end
of the communication path has made it impossible to talk to the other sta-
tion.
Remember that disabling the encryption will mean that your transmissions
are no longer secure. Return to the encrypted mode as soon as possible,
and do not discuss any critical or confidential information while in the
non-encrypted mode of operation.
Lock
Switch the Toggle switch to lock the top-panel keys; this can be enabled
to prevent radio settings from being disturbed.
