System Setup
The system setup submenu page (Fig. 71a) is used to select the operating mode,
time offset, and screen preferences. The GPS II has three operating modes:
• Normal Mode operates the unit at maximum performance, and provides a
battery of life up to 12 hours on alkaline batteries.
• Battery Saver Mode (Fig. 71b) is suitable for most applications, and extends
battery life to up to 20 hours on alkaline batteries by reducing the receiver’s
update rate when navigational conditions permit (e.g., you’re traveling a steady
course without significant variations in speed or heading). Since battery saver
mode changes the update rate based solely on navigational conditions, the bat-
tery life will vary accordingly.
• Simulator Mode allows you to operate the unit without acquiring satellites,
and is ideal for practicing or entering waypoints and routes while at home.
To select an operating mode:
1. Highlight the ‘mode’ field, and press ENTER.
2. Select a mode, and press ENTER.
