Screen Backlighting
The GPS II + ’s backlight feature illuminates the screen display for a user-defined
interval (the default is 15 seconds) after every keystroke. There are three stages of
backlighting. When backlighting is on, a bulb icon will appear at the bottom left of the
sky view (Fig. 25). To adjust the duration of the screen backlighting, refer to the opera-
tion setup section (see p. 75).
To turn the screen backlighting on:
1. Cycle through the three levels of backlight by pressing the red power key.
To turn the screen backlighting off:
1. Press the red power key.
Whenever the GPS II + ’s backlighting is off, the bulb icon disappears from the
Satellite Page.
