What Beeper Tones Mean
Setting the Screen Contrast
You may adjust the contrast setting for best viewing of the
display screen.
To Set the Screen Contrast:
1. Press and hold the BACKLIGHT/CONTRAST key
on the side of the unit until the Backlight/Contrast
page appears.
2. Press the LEFT or RIGHT side of the ROCKER
keypad to adjust the level of contrast, (Left to
lighten and Right to darken). Press the ENTER key
to save.
Using the Backlighting Feature
You may turn on the screen backlighting for easy viewing in
dim and dark lighting conditions. The backlight is set at the
factory to turn Off after 15 seconds to extend battery life. To
select from shut-off time options, refer to the section on Setup
Options.
To turn the backlighting On and Off:
1. Press and release the BACKLIGHT/CONTRAST key
to toggle the backlight ON and OFF.
2. You can also turn the backlight function ON or OFF
by pressing and holding the BACKLIGHT/
CONTRAST key until the ‘Backlight/Contrast’
window appears. Then, press the ROCKER keypad
UP for ON or DOWN for OFF.
If set for automatic time-out, it will shut-off automatically
after the last key press. Pressing any key will reactivate the
backlight. If the timeout is set for ‘Stays On’ it will not turn off.
Extended use of backlight will significantly reduce battery life.
Setting the Correct Time
If the time displayed in the ‘Time’ field of the Map Page is
not the correct time for your Time Zone, you will need to set
the time. Refer to ‘Time Settings’ on page 32.
To adjust the screen contrast,
use the LEFT or RIGHT
ROCKER keys to move the
contrast adjustment lever.
Use the UP or DOWN
Rocker keys to move the
Backlighting switch up for ON
or down for OFF.
