Power Saving
Your iFINDER contains a battery capacity indicator and will flash low
battery warning messages when battery power declines to a certain
level. When plugged into the DC cigarette lighter adapter, the power
indicator displays an External Power message. This message some-
times appears for a few minutes when using fresh batteries.
The Power Save feature conserves battery power by changing the posi-
tion update rate. Test the power save feature in known surroundings
and determine its capabilities before venturing into unknown territory.
Experiment with modest settings, such as 1 second update (300 ms) or
1 second update (200 ms) and see if accuracy is adequate for you.
WARNING:
Full power settings will always give you the best, most
accurate performance with the iFINDER. Power save
functions can extend battery life, but aggressive power
saving settings can reduce GPS accuracy, particularly in
demanding situations when signal availability is less
than ideal. It is up to you to decide if position accuracy
or battery consumption is the most important considera-
tion for a particular navigation situation.
In potentially risky navigation situations, consider the standard oper-
ating procedure of professional cave explorers, who never enter an un-
developed cave with fewer than three sources of light (a main light and
two backups.) Even if you do carry a couple of spare sets of batteries,
remember: a prudent navigator never depends on only one source of
navigation information. A good map and compass are important com-
panions for you and your iFINDER.
