REFERENCE Contrast and Backlighting When screen backlighting is on, a bulb icon will appear in the lower-left corner of the Satellite Status Page. The Position Page shows you where you are, what direction you're heading and how fast you're going. 30 Contrast and Backlighting On page 25, we introduced display contrast and backlighting adjustments accessible from the Satellite Status Page. Display settings can also be adjusted from any page, by pressing the red power key. When backlighting is on, a bulb icon will appear on the Satellite Status Page, to the bottom left of the sky view. To adjust the duration of the screen backlighting, refer to the operation setup section (see pg. 77). To adjust the screen contrast and/or backlighting from any page: 1. Press the red power key momentarily. A window will appear showing the current contrast and backlighting settings. 2. Press LEFT or RIGHT on the rocker keypad to adjust the level of contrast, and press ENTER to save the new contrast setting. 3.

Position Page The second page in the GPS III+'s main page sequence is the Position Page. This page shows you where you are, what direction you're heading, and how fast you're going, and it's most useful when you are traveling without an active destination waypoint. The graphic heading display at the top of the page indicates the direction you're heading, or track, only while you're moving. Directly below this display are the speed, average speed, trip timer, trip odometer and sunrise/sunset fields (default). The sunrise/sunset times indicated are for your present position. These times, and the current time display in the lower-right corner, can be displayed in local or UTC (universal) time. The lower left-hand corner of the page shows your current latitude and longitude in degrees and minutes (default). The GPS III+ uses this basic information to mark exact positions as waypoints, which help guide you from one place to another. Average speed, sunrise and sunset times (at
