FOBO Tire In-Car unit is a complicated device that performs many functions. Due to
shielding effect of the car body metal, some drivers may face difficulty to get sensor
signals to their smartphone when sitting inside the car. This problem may be further
aggravated when driver places the smartphone close to the body, in trouser pocket or
waist pouch. The In-Car unit is designed with an efficient antenna that can pick up sensor
signals up to 10dB better than a usual smartphone. With the In-Car unit, user can be
assured of good signal reception from the sensors.
The In-Car unit is designed to be placed anywhere inside the car, please do not remove
from inside the car. FOBO Tire system requires the In-Car unit to remain inside the car in
order to be fully functional as a system. Note that In-Car unit is not water-proof. Best
location to place the In-Car unit will be to affix it on the lower dashboard position but
away from direct sunlight. Use the Velcro double side tape provided in the packaging to
secure the In-Car unit. Do not enclose the In-Car unit inside any metal compartment or
box. This will make the In-Car unit unable to receive signals from tire sensors.
The In-Car unit will also synchronize all user settings changed on the smartphone every
time it wakes up. For any changed settings in the app, it will only be synchronized in the
next In-Car unit wake up cycle. Alternatively you can long press the side button of In-Car
unit until you hear a beep, in order to put the In-Car unit into synchronization mode with
the smartphone app. Note that the In-Car unit will go into sleep if the car is not moving
for a long time. This is to conserve the battery life of In-Car unit. However the sensors
will continue operational for 24x7 and alert user in case of flat tire when user is away
from the car.
The In-Car unit is also meant to be a back-up alert device in case user did not bring
smartphone into the car or the smartphone is set to silent mode. When there is a tire
problem, the In-Car unit will produce audio and visual LED alerts to inform user of a tire
problem. To silent the repetitive audio alerts, short press the side button once. In case
user wants to reproduce the alert to check the location of problematic tire, short press the
side button once more.
In-Car unit will produce a start-up tone “di da” every time it wakes up after detecting a
car movement. This tone is also to inform the user or driver that In-Car unit is operational.
