BACKLIGHT
To turn the Backlight On, press and release the L button (< 2 seconds). The Backlight will remain On for the duration time set (a
Set Utilities selection) unless you turn it Off during that time by pressing S again.
• The Backlight will come On (even if set OFF) when alarms strike and remain On until turned Off by pressing S, or it turns Off
automatically after 10 seconds .
• Pressing and releasing the L button (< 2 seconds), while the Backlight is On, will turn it Off.
• Depressing the L button for 2 seconds, while the Backlight is On, will reset the duration timer and extend the On time to the
full duration time set.
• If the L button is depressed for more than 60 seconds, the Backlight will be disabled and not turn On until the button is
released then pressed/released again.
• The Backlight will be disabled when there is a Low Battery alarm condition, and be re enabled once the battery is replaced.
• Extensive use of the Backlight reduces Battery use life.
• Turning the Backlight Off when it is not being used will help extend Battery use life.
• The Backlight does not operate when the unit is connected to a PC or Mac.
Auto Glo (TECH FREE mode only):
When Auto Glo (a TECH FREE mode Set Utilities selection) is set On, Backlight operation on the surface in TECH FREE mode is
controlled as it normally would be by the L button and duration time set.
However, upon entry into TECH FREE dive mode, the Backlight activates (turns On) automatically and remains On throughout
the full dive until entry into Surface mode when the Backlight operation reverts to normal.
