Adjusting Contrast
If lighting conditions make it hard to view the display screen, the
backlight can be adjusted for optimum viewing.
1. 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, DOP number (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.
