SYSTEM SETUP
The GlobalNav 200 has several menus and com-
mands listed under the “System Setup” label on
the main menu. These commands affect the ba-
sic operation of the unit. To use them, press the
MENU key, then highlight the “System Setup” la-
bel. Press the right arrow key. The screen shown
at right appears.
BACKLIGHT
The GlobalNav 200’s display has lights that can
be turned on for night use. To turn the lights on,
simply press the PWR key. To turn them off, press
the PWR key again. An indicator on the satellite status screen (Group
“O”) shows when the lights are on.
The GlobalNav 200 automatically turns the lights off after 30 seconds to
preserve the battery power. It will do this even if the external power is
applied to the unit.
The time delay is adjustable from 5 to 240 seconds. You can also turn the
lights on continuously from this menu. Use the “Light Dly” (light delay)
menu to change this. Highlight this menu, then press the right arrow key
to increase the time the lights are on, the left arrow key to decrease it.
Press the EXIT key to erase this menu.
SOUND
To turn the speaker off, highlight the “SOUND” label as shown above,
then press the left arrow key. Note: This turns the speaker completely off.
The unit will not sound a tone when a key is pressed, nor will any alarm
sound. The alarm messages will still flash on the screen, however.
CONTRAST
To adjust the display’s contrast, highlight the “Contrast” label on the “Sys-
tem Setup” menu as shown above. Press the right or left arrow keys until
the screen’s contrast is best for the lighting conditions. Press the EXIT
key to erase this screen.
