Power Saving
The iWAY will flash low battery warning messages when battery power
declines to a certain level. The power save feature conserves battery
power by changing the position update rate. We recommend you test
the power save feature in known surroundings and determine its capa-
bilities before venturing into unknown territory. Experiment with mod-
est 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 iWAY. Power save functions can extend bat-
tery life, but aggressive power saving settings can reduce GPS ac-
curacy, particularly in demanding situations when signal availabil-
ity is less than ideal. It is up to you to decide if position accuracy or
battery consumption is the most important consideration for a par-
ticular navigation situation.
