Menu > Display Opt > Backlight Off
An electroluminescent backlight is included for night jumps. The back light will
only illuminate continuously during freefall and under canopy. Since the backlight
is a heavy drain on the battery charge, we recommend that you leave it
disabled
unless you are actually making a night jump. Before a night jump, fully charge
the battery to ensure that your N3 will have the full power throughout your entire
jump. Please be advised that the alarms and backlight cannot operate
simultaneously.
Therefore, if on a night jump and using N3 as a visual
altimeter, the alarms
must be disabled
in order for the backlight to
remain on throughout the entire jump. If the alarms are not disabled,
the backlight will go out each time an alarm sounds (freefall and canopy
alarm groups).
On the Menu screen, scroll to and select
Display Opt
.
The current state (if the backlight is On or Off) will
be displayed.
This screen shows that the backlight is Off.
This screen shows that the backlight is On.
On the Ground Screen, this symbol indicates the
backlight is on.
