Battery Saver (GPS Save)
This function will turn the GPS power source Off after the
programmed timer expires if position data is not determined
during the maximum catching time (approximately 5 minutes).
To prevent unnecessary battery consumption, when there are
many reception satellites, the GPS is stabilized and position
data can be determined, the GPS power source repeatedly
turns On and Off.
1 Access Menu No. 404.
2 Select [Off], [1], [2], [4], [8] minutes, or [Auto].
[Off]: The built-in GPS receiver function is always On.
[1 min] to [8 min]: When set to 1, 2, 4, or 8 minutes, the
GPS off time starts at the selected duration if position
data is not determined during the maximum catching time
(approximately 5 minutes).
[Auto]: When set to Auto, the GPS Off time starts at 1
minute for the first time, then progresses to 2 minutes,
4 minutes and 8 minutes each additional time. The GPS
Off time remains at 8 minutes thereafter. However, after
having determined your position for the duration, if the
GPS cannot pinpoint your location, the GPS Off time will
restart at 1 minute.
Note:
◆ Position precision may be improved by setting the Battery Saver
(GPS Save) function to [Off].
◆ When GPS cannot be received, turn the power ON in a clear
