Battery Level Indicator

The Satellite Page also features a battery level indicator,

located below the status field to the left of the sky view,

which provides a graphic display of the condition of the

internal batteries.

The battery level indicator is calibrated for alkaline

batteries. Ni-Cad and lithium batteries will not

accurately display the battery level due to voltage

differences. No other receiver functions are affect-

ed by using Ni-Cad or lithium batteries.

It’s always best to store your GPS with the batteries

installed to preserve the internal memory and data.

The GPS 38 features a self-charging lithium battery

that continually maintains a full charge while bat-

teries are installed. The lithium battery will maintain

the internal memory for 3 months in the event that

the batteries are removed or totally discharged.

Screen Backlighting

The GPS 38’s automatic backlight feature illuminates

the screen display for a user-defined interval (the default is

15 seconds) after every keystroke. When backlighting is on,

a bulb icon will appear at the bottom left of the sky view.

To turn the screen backlighting on or off:

1. Press the

key.

2. To adjust the duration of screen backlighting, refer to the

operation setup section (page 46).

Using the screen backlighting can greatly affect

battery life. If you’re using your GPS primarily in

daylight hours, you should keep the backlight time-

out at the default 15 second setting.

A bulb icon will appear on

the Satellite Page whenever

the screen backlighting is

on. The backlight will turn

on for the time selected after

every keystroke.
