4 GPS4.3.5 Internal GPS Unit SaveIf the reception is inferior (such as while you are in a building), the GPS unit continues searching for asatellite resulting the battery longevity. To prevent unnecessary battery consumption, this functionwill turn the GPS power source Off for the programmed duration of time if position data is notdetermined during the maximum capture time (5 minutes).Set the timer through Menu 201.Possible choices are “Off”, “1 min”, “2 min”, “4 min”, “8 min” and “Auto”.MaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)approx. 5 min. approx. 1 min. approx. 5 min. approx. 1 min. approx. 5 min. approx. 1 min. approx. 5 min.Figure 4-15 GPS Unit Behavior if 1 min is SelectedGPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFMaximumCatching TimeGPS ON(Catching + Tracking)GPSOFFFigure 4-16 GPS Unit Behavior if Auto is SelectedMaximumCatching TimeGPS ON(Catching + Tracking)approx. 5 min. approx. 1 min. approx. 5 min. approx. 2 min. approx. 5 min. approx. 4 min. approx. 5 min. approx. 8 min.approx. 5 min.4.3.6 Battery Operating Time during the Concurrent Use of theInternal GPS UnitAssumed uses of the TH-D72A/E include transmitting beacons on band A in APRS mode andtransmitting voice on band B in dual band mode with the internal GPS unit on.Following is the table that provides the estimated battery operating time.
