▲Please read this User’s Manual carefully before using this product.

▲TPMS-203 has been developed specifically to address the challenges of tyre pressure

monitoring on large-scale and multi-wheeled commercial vehicles.

▲TPMS-203 is designed to monitor tyre pressure and temperature. It is not designed to

provide warning of sudden critical tyre damage and blowout caused by external effects.

The driver should react promptly to any warning and correct the problem.

▲Tyres may fail for other reasons except for low pressure or overloading. Always be on

alert for any tyre problems as indicated by unusual noises, vibrations, uneven tread wear,

or bulges on the tyre! If any of these symptoms occur, please have the tyres checked

immediately by a professional!
