Saving the Battery during Reception
One of the important features of the
FTA-750L/FTA-
550/FTA-450L
are its battery saver, which “puts the
radio to sleep” for a time interval, periodically “waking
it up” to check for activity. If somebody is talking on
the channel, the
FTA-750L/FTA-550/FTA-450L
will
remain in the “awake” mode, then resume its “sleep”
cycles. This feature significantly reduces quiescent bat
-
tery drain.
To activate the battery saver, select one of the following
interval time ratios on the item “
BATTERY SAVE
” of the
CONFIGURATION
menu in the SETUP mode.
