The heading display displays the current heading of the vessel.
The compass must be calibrated and north set for this display to
be correct. Please see your Gladiator’s Owner’s Manual for these
instructions.
The heading on the display may not match your compass or your
GPS. This is normal. Once the Gladiator system’s compass has
been calibrated and north has been set, it may be the most accurate
heading display on your boat.

LED Backlight Control
There is an LED backlight to be used in low light conditions. The
backlight is activated and adjusted by pressing and holding the
directional input dial for greater than 4 seconds. The backlight will
cycle through six (6) separate intensities while the dial is being held
down. Let up on the dial when the desired intensity is reached.
