FOBO Tire sensor units are designed to be robust and working reliably 24x7 to provide
tire information. It is designed to be water proof (IP57) and using special engineering
plastics, will be able to withstand road salts or other common automotive chemicals
(petrol, engine oil, car wash shampoo, etc).
Extreme care had been exercised when designing the mechanical sealing to prevent air
leak. There is no need to screw in the sensor extremely tight. Apply a reasonable hand
twist force to ensure the sensor is securely installed and should be able to be removed by
hand with ease.
Note that the sensor position is fixed during installation. This is to ensure the app and In-
Car unit able to identify problematic tire position. If the sensor position is mixed up, you
can do a Rotating Tire procedure from the app to identify the sensor positions again.
A missing sensor or damaged sensor can be replaced easily using the replacing sensor
procedure. In the app screen, click on the tire position that needs to be replaced for 5
seconds. An instruction message will guide you to install the new sensor. Individual
replacement sensor is available for purchase from www.my-fobo.com.
