Operation
The third section of the main menu allows you to speci­
fy the operating mode and enter an initial position by man­
ually entering coordinates or by using a reference waypoint.
The GPS 89 has three available operating modes:
Normal Mode operates the unit at maximum perfor­
mance, and should picwide a baiieiy life of 15 hours on
alkaline batteries.
Battery Saver Mode b suii^le for most applications,
and extends battery life to up to 20 hours on alkaline
batteries by reducing the unit’s update rate when navi-
gatioital conditions permit {e,g„ you’re travelling a
steady course without constant speed or heading varia­
tions).
Simnlator Mode allows you to operate the unit without
acquiring satellites, and b ideal lor practicing or enter­
ing waypoints and routes while at home.

Initial Position Entry
The initial position field allows you to enter a beginning
position either to speed up the acqubition process if the unit
has moved more than several hundred miles with the power
off or define a starting point for a simulated trip. You may
select a known waypoint as your starting position, or define
a dbtance and bearing from a known waypoint to calculate
your starting latitude and longitude.
Keep in mind that while entering an initial position may
speed up acqubition, entering an incorrect initial position
will have an adverse effect on the receiver^ ability to find the
necessary satellites in order to calculate an accurate position.
