37) Auto-brightness is not working properly
The 7700 PRO will adjust the display brightness based on the time of day.
Your unit will not know the local time until it locks onto satellites, therefore the auto-brightness
will not function until satellite lock is achieved.
ALSO, be sure to check the brightness setting:
1. Tap anywhere on the map screen.
2. Tap on CONFIGURE.
3. Tap on BRIGHTNESS CONTROL.
4. Make sure it is set to AUTO.
