2 W401 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.





5. Use the alan key provided to tighten.
cPut the marked No. 1 tire sensor to the tire
which is marked No. 1. as step as. photo
and follow steps:
1. Install the tire sensor to the valve.
2. Use the nylok screw and tighten up with the
tire sensor. (Please use the screwdriver
which is included to the accessories bag)
3. Adjust the tire sensor’s angle (paste on the
surface
of the wheel), then tight up the with the
nylok screw.
4. Put on the valve’s cap, and finish the
installation.
When there is a need to re-install the tire
sensor, please use a new nylok screw in
order to prevent the usage of the old ones.




dPlace the No. 2 tire sensor to the tire which i
s
marked No.2, and set up the other 2 sensor
s
in the same manner as shown in the step “c”.

eMake sure there is no other liquid or dust
present around the area of the tire sensor.

fAfter installation, inflate the tire to the
appropriate air pressure as suggested in
each vehicle’s user manual.
gBalance the tires with the tire balance
machine.
hPlace the tires back to it’s corresponding
position as shown in the photograph on

the day and darker in the night to ensure that the user will be able to read the LED
Display clearly and not be affected by external lighting.

2. Operation to Change Display Mode
W401 has 3 different modes, they are Tire Pressure Display Mode, Temperature Display
Mode, and Pressure-Temperature Rotation Mode. The display will show the tire pressure
mode once it is turned on, to enter the temperature mode press on the MODE button once
and to display pressure-temperature press it another time. The system will continuously
monitor the tire pressure, tire temperature, battery voltage, no matter what kind of information
are being displayed and will notify the driver whenever anything abnormal happens. If the
user does not change from the factory default, the system will show the tire pressure display,
the 3 modes of display are as follows:
a. Pressure Display Mode: Display of 4 tires pressure and battery voltage unit only.
b. Temperature Display Mode: Display of 4 tires temperature and battery voltage unit only.
c. Pressure-Temperature Rotation Display Mode: Rotating display of tire pressure and
temperature with a constant display of battery voltage.

tire pressure set up, Tire Temperature-Over Temperature Warning, Operation Mode and for
other parameter settings, please refer below for the relevant process:
NOTE: The user should change the suitable pressure unit for own vehicle before entering
into the setup mode.

FRONT TIRE-Standard Cold Tire Pressure Setting Mode
When the tire is under normal inflated condition, the pressure will increase and decrease
simultaneously with the temperature, normally, there will be 1psi (7kPa) fluctuation when the
temperature differs about 10OF (6OC), and this is normal physics phenomenon. ORO suggests
that, when checking on tire pressure, it’s important to keep the tire pressure under suggested
specifications, the Cold & Low tire pressure setting will be recognized as a warning, however,
when the pressure is higher or lower than 25% from the cold tire pressure setting value, the
system will notify to the driver.

Warning: Standard Cold Tire Pressure setting value, please check on each vehicle’s user
manual.

The LR tire symbol will be flashing green with a blue “3” on the display. This means the LR
tire is ready for the set up as per below, Fig. 1, in the meantime, the user should deflate the
tire pressure rapidly over 0.3bar/30kPa or 4 psi within 15 sec. until there is a beep sound,
which means the user has completed the set up for LR tire. The system will then proceed
back to the normal display mode. If there is no need to set up the LR tire sensor, just press
the SET button to skip this process. The system will then proceed to LF tire sensor set up
mode as shown below Fig. 2.
