User Manual

Caution: the system is wireless RF product; therefore, it may not receive a signal due to the poor environment or
incorrect operating either on incorrect installation. When the system continually cannot receive any signal from any
tire sensor more than 10 minutes since the system has been switch on for monitoring, the system will shown “ E2 ”
and turn on the RED abnormal LED light with alert sound. In this case, it may cause by a RF interference
environment, a driver need to drive the vehicle and leave the place where are running. If the display still cannot
receive any correct signal from tire sensor, then, a driver need to find a close qualified tire maintain service for
checking or maintain. It may cause by a tire sensor damages or battery power consumption. (Battery in normal
condition can be used more than 7 year, but in abnormal condition, the tire sensor will continually send warning
signal to the driver, thus it wills consumption the battery quickly than normal prediction.)
W401A Tire Pressure Monitoring System
ORO-W401A Tire Pressure Monitoring Systems (TPMS), can monitor and provide tire pressure, tire temperature
and car battery information by real time to help the driver to control and keep the normal tire pressure in order to
reduce the fuel consumption and extend the tire life, and also through the battery information, the driver can
change the battery before happens any bug and reduce the % of vehicle breakdown on the road.
ORO-W401A Tire Pressure Monitoring System, includes 4 tire sensors and 1 receiver display, the
TPMS can monitoring the pressure/temperature by snap-in installation into the tire, and transmit the
tire information to the receiver by wireless. The TPMS display will alarm when any abnormal happens
to the tire in order to prevent any possible accidents which may happen to the driver/vehicle.
