System Scope of Use and Warnings
ŶSystem Installation and Usage
Use of the TPMS requires that qualified personnel according to the instructions here have
properly installed it. This system is suitable for using on a passenger car, SUV and 4X4
tires, with up to maximum cold inflation pressure of 600kPa=87 psi (Gauge) or
700kPa=101psi (Absolute), below instruction is Gauge value mentioned.
ŶReacting to Alerts
When an alert or warning is received, reduce vehicle’s speed and proceed to a safe location
to stop where the tire can be inspected and /or serviced.
The low-pressure alert indicates that the air pressure has dropped to a selected minimum
and a high-temperature alert indicates that the temperature of the tire content has surpassed
the threshold value set.
Caution
The system is a wireless RF product; therefore, it may not receive a signal due to poor
environmental conditions or incorrect operation or incorrect installation. When the system
continuously cannot receive any signal from any tire sensor for more than 10 minutes
since the system has been switched on, the display will show “ E2 ” and activate the RED
abnormal LED light along with an alert sound. In this case, a RF interference environment
may have caused it; a driver will need to drive the vehicle to a different location. If the
display is still unable to receive any correct signal from tire sensor, the driver will need
to find a nearby qualified tire maintenance service to check or carry out maintenance.
This abnormality may be caused by a damaged tire sensor or excessive battery power
consumption.

2W401 Tire Pressure Monitoring System
ORO-W401 Tire Pressure Monitoring Systems (TPMS), can monitor and provide tire
pressure, tire temperature and car battery information in real time to help the driver
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 any incident occurs and reduce the possibility of vehicle breakdown
on the roads.
ORO-W401 Tire Pressure Monitoring System, includes 4 tire sensors and 1 receiver
display, the TPMS can monitor the pressure/temperature by snap-in installation into
the tire, and transmit the tire information to the receiver by wireless. The TPMS
display will trigger an alarm when any abnormalities happen to the tire in order to
prevent any possible accidents which may happen to the driver/vehicle.
