Setting the Screen Backlight
The screen backlight can be set to one of three levels (low,
high or off). At power on, the screen backlight is set to high
level. Follow the sequence below to choose another level:
- Hold down the PWR button for 2 seconds : Backlight
drops down to low level
- Hold down the PWR button again for 2 seconds: Back-
light turns off.
- Hold down the PWR button again for 2 seconds: Back-
light comes back to high-level illumination.
Using the backlight makes the screen display easier to see,
but it also drains the batteries more quickly.

Getting a Position Fix
The unit is designed to fit comfortably in your hand. Hold
the MobileMapper in the palm of your hand with the antenna
pointing towards the sky.
MobileMapper’s antenna needs to have a relatively unob-
structed view of the sky. This allows the unit to choose from
all satellites currently available.
If the view of the sky is poor due to large cliffs or buildings,
heavy foliage or other obstructions, the satellite signals can
be blocked and the receiver may take longer to compute a
position fix.
To prevent accidently
turning the backlight on
and leaving it on, the unit
will turn the backlight off
when there have been no
buttons pressed for 4
minutes. Pressing any
button will turn the back-
light back on in this
instance. You can change
the time delay for the
backlight using the Light
Timer option in the Setup
menu (see page 56).
