1 Introduction
2 Function
The monitor’s function is to receive the temperature and pressure information transmitted
from a sensor fitted to each tyre and display this information on the screen in the specific
units of measurement of your choice.
The monitor will emit an alarm when a tyre pressure or temperature varies markedly
from the targeted tyre pressure and/or temperature. The system will detect
thigh or low air pressure as well as high temperature or rapid leakage from the tyres.
The monitor will flash the red LED icon and an alarm will sound to remind the operator
to check if the tyres are high or low in air pressure, leakage, high temperature or the
monitor’s battery is low, or there is a problem with a sensor. This advanced tyre monitoring
system offers these great features and benefits, is reliable, lightweight and compact.

Congratulations on purchasing the new TYRE PRESSURE
MONITORING (TPMS).This system is a safety system
for monitoring vehicle’s tyre air pressure and temperature. It
consists of external mounted tyre pressure wireless sensors
fitted to the vehicle’s ryre valve and a hand-held monitor.The
sensor will monitor the tyre’s air pressure and temperature.The
sensor transmits the tyre pressure and temperature information
to the dash-mounted/hand-held monitor.
