Vari-Power™ Battery Saver Feature
The AccuNav Sport™ has a five-level power saving
feature that can extend the life of the batteries consid-
erably. It does this by changing the update rate of the
GPS receiver inside the unit. When you first turn the
AccuNav Sport on, the update rate is once per second.
In other words, the GPS receiver calculates and sends
your position to the display once per second. You can
lengthen this time to as little as once every five seconds.
The longer the update rate, the less power is drawn from
the batteries. For example, less power is drawn from the
batteries when the unit is in the five second update rate
than the one second rate. There can be exceptions to
this rule, however. Whenever the AccuNav Sport is
trying to lock onto the satellites, it automatically goes
into the one second update mode. If you are walking in
a wooded area with the unit set on the five second
update mode, the unit may lose its lock on the satellites
