to put the In-Car unit into synchronization mode with the smartphone App.
The In-Car unit is also designed to be a secondary alert device in the event of a
deflated tire. This is to cover situations when you do not have your smartphone with
you while driving or if your smartphone‟s battery is dead. When there is a tire
pressure alert, the In-Car unit will produce an audible and visual LED alerts to
inform you of a tire pressure problem. To silence the repetitive audio alerts, just
quick press the side button once. To check back the position of the problematic tire,
a quick press on the side button once more and the LED of the problematic tire
position will light up.
The In-Car unit will emit a start-up tone every time it wakes up upon detecting the
car‟s movement. This tone is also to inform you or the driver that the In-Car unit is
operational. In case you do not hear this tone when start moving the car, please
check the state of the In-Car unit by a quick press on the side button once. If you
hear a long single tone that means the In-Car is still in sleep mode. You can change
the detection sensitivity in the FOBO Tire App by going to Edit Car Profile ->
Advance Setting screen to adjust the In-Car unit sensitivity. In some electric cars,
the In-Car unit may require higher sensitivity to detect the car moving.
NOTE: Unnecessarily waking up the In-Car unit will drain battery.
