Safety instructions

Please check the following items before using this product

• This product is designed for use on public roads, so do not use it in harsh conditions such as track driving.
• If you want to check the receiver screen while driving, be sure to do so while the vehicle is stopped.
• In order to extend the life of the sensor battery , the device will enter power saving mode if the vehicle is stopped for a period of time (approximately 10 minutes). In power saving mode, the sensors will automatically transmits data if the vehicle speed more than 20 km/h.
• Tire pressure and temperature change according to the weather, time of day and road conditions. Especially when driving, And it is normal that the pressure value fluctuate suddenly after receiving the signal when car started.
• Tire pressure will naturally drop over time and this drop has nothing to do with this unit.
• Please make sure the sensors were installed correctly to prevent it from falling off due to vibration or other reasons.
• When installing sensors, tight the sensors correctly. If too tight, it may damage the rubber gasket of the valve and sensor. So be careful when installing..
• After installing the sensor, use soapy water to check if there is air escaping from the sensor.
• This product can monitor, warn and remind abnormal tire pressure, but it cannot prevent the occurrence of tire blowout accidents.
