NAV DIAGNOSTIC MODE
• Upon manual activation (if NAV was previously set ON and the
d.i.P shut Off), or if the SET NAV screen is accessed from the
NORM SURF MAIN, the unit will enter NAV Diagnostic Mode
(Fig. 60), displaying the NAV segments of the LCD.
• Diagnostic Mode checks the display and battery voltage to en-
sure everything is functioning properly.
• If a Low Battery condition exists, the Battery icon will flash
(Fig. 61a) and the d.i.P will shut Off.

NORM Mode. The NAV Set Menu also includes a SET NAV
BACKLIGHT MODE selection.

ously selected (refer to page 55) -
