this product is used for passenger cars with tire pressure range

of 0-3.5bar.

the tires are prone to overheating during long-term driving or

High-speed driving in summer, and low temperature when

Parked outdoors for a long time in winter. Due to the principle of

Thermal expansion and contraction, the tire pressure may change

Higher or lower, which is normal.

If the vehicle is parked for a long time, there will be natural air

Leakage in the tire, and the tire pressure value will also be

Reduced, which is a normal phenomenon.

Incorrect installation will affffect the monitoring accuracy of the

Product and even cause damage to the product. Please go to a

Professional automobile 4S shop for installation. If the transmit-

Ter needs to be disassembled again, a new valve should be

Replaced for installation.

When the receiver sends out a buzzer alarm, please stop in the

Safe area to check whether the tire is normal or go to the nearest

Automobile repair shop for tire inspection.
