Backlighting
The monitor is equipped with a light sensor and a motion sensor, the backlight will only
turn on when it detects that your vehicle is in motion and it is dark enough to need the
backlight. If the monitor is operating on the internal battery, the monitor will "go to sleep"
to conserve the battery if the motion sensor detects that you have stopped for a time, an
example would be for fuel. The motion sensor will wake it up to monitor the tire data once
you are back under way. The backlight can be turned on manually by pressing any button.
It can be turned off by pressing the "+" button for 3 seconds.
