take and reduces battery consumption.

"3min", "5min" on the item "TX TOT" of the CONFIGU-
RATION menu in the SETUP mode.

Saving the Battery during Reception

One of the important features of the FTA-750/FTA-550
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-
750/FTA-550 will remain in the "awaking" mode, then
resume its "sleep" cycles. This feature significantly re-
duces quiescent battery 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.
50% ... Sleeps for 100 ms after 100 ms awaking
70% ... Sleeps for 250 ms after 100 ms awaking
80% ... Sleeps for 450 ms after 100 ms awaking
90% ... Sleeps for 900 ms after 100 ms awaking
