Adjusting Contrast

If lighting conditions make it hard to view the display screen, the

backlight can be adjusted for optimum viewing.

Press the PAGE/ESC Button until the satellite page is displayed.

2. Move the Direction Button either to the left or right and the

contrast display setting will be shown. Move to the left or right

to adjust the lightness/darkness of the screen. See 14-A.

3. After adjustment, press the OK Button or the PAGE/ESC

button to exit.

Extensive use of the backlight will reduce battery life.

Night Viewing

Press the PWR Button to turn on backlighting. The amount of time

the backlighting is on can be adjusted from the Settings Menu.

See System Settings Section on page 20.

Obtaining Satellite Signals

The Satellite page shows the GPS satellites that are available and

their signal strength. Once a satellite is acquired and fixed, the

signal bar for each satellite will turn dark. Signal strength of the

satellite signals will be shown by length of signal bar. The longer

the signal bar displayed, the stronger the signal. This page also

displays which satellites are locked on, your location coordinates,

background lighting on/off, DOPnumber (the lower the number the

better the satellite signal), and battery status. See 14-B.

At least three satellites are needed for the Galileo

™

to operate

properly. When the unit is searching for satellites, it may take

several minutes to acquire three or more strong signals from the

orbiting satellites. When you use the Galileo

™

for the first time,

perform a Cold Start (See page 15) or when you are over 500 miles

from where the Galileo

™

GPS was last turned on, the unit may

require longer (5 to 10 minutes) than normal time to acquire the

necessary three or more satellites. After the satellites are acquired

and fixed, your position is identified and the display changes to

the map page.
