You can select from seven receiver
sleep
(power-down) durations, ranging from 300 ms
to
1 second, or else enable the ABS (Automatic
Battery Saver) mode, which senses channel
activity and automatically adjusts the moni-
tor/sleep time ratio according to recent operat-
ing history. Refer the table below for a
comparison of selectable durations.

SAVE GHI
TX Save
A
good operating habit is to use the lowest
transmitter power necessary to maintain reliable
communications. As described on the box on
page
24, the
FT-51R offers a choice of five levels
of power output: one high and four low
-
(economy low),
I
, L L
and Also, the
FT-51R
can reduce transmitter current drain further
with its smart
Tx Save feature. This conserves
battery life by reducing power output when the
microprocessor determines it is not needed. It
monitors the signal strength of the last-received
signal, then the microprocessor selects one of the
four Tx output power levels, according to the
received signal strength.
Note that the power level cannot be se-
lected with
Tx Save enabled, and if you are using
a 4.8-volt battery, Tx Save has no effect (in actual
power output) when
I
power level is selected.
