NOTICE
FCC & E-Mark Notice
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
factoring measures.
z Reorient or relocate the receiving antenna.
z Increase the separation between the equipment and receiver.
z Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
Caution: Any changes or modifications in construction of this device which are not expressly approved by the
party responsible for compliance could void the user’s authority to operate the equipment.
To comply with the FCC RF exposure compliance requirements, this device and its antenna must not be
co-located or operating to conjunction with any other antenna or transmitter.
System Scope of Use and Warnings
Tire Pressure Monitoring System, TPMS
This system is a sensing device designed to measure and display tire operation and / or activate an alert to the
driver when pressure and temperature irregularities are detected. It is the responsibility of the driver to react
promptly and with discretion to alerts. Abnormal tire inflation pressure should be corrected at the earliest
opportunity.
System 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 use on a passenger car, SUV and 4
76 Psi (Guage) or 90psi (Absoulte), below instruction is Guage value mentioned.
Reacting 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.
X4 tires, with up to maximum cold inflation pressure of
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.
Use of Chemicals
Temporary resealing or re-inflation products containing internal sealants or propellants in any tire assembly may
adversely affect the operation of the sensor/transmitter.
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.

W401A TPMS INSTALLATION
1. Display Installation:
a. Firm the magnetic holder in the suitable place. (Suggest place , as shows in the picture)
b. Plug in the USB cigarette power cable on the back of display.
c. Put the display on the magnetic holder.
d. Plug in the power cable to the cigarette lighter power connection.
2. Tire Sensor Installation:
Step Operation Process Photograph
a Take off the 4 tires and mark 1~4 for each tire position.
No.4 = Left Front Tire ； No.1 = Right Front Tire。
No.3 = Left Rear Tire ； No.2 = Right Rear Tire。
b Take off the tire and bleed the air, then should change to
the ORO-TEK TPMS valve, and follow the steps:
1. Snap in the valve from the internal edge side of the
wheel.
2. Adjust the valve’s angle, and make the valve be
vertical by the edge of the wheel.
3. Put on the circle screw from the outside of the wheel.
4. Tight up the valve with the nylok screw from the
outside of the wheel.
5. Use the 6 angle screwdriver to tight up.
b
c Put the marked No. 1 tire sensor to the tire which market
No. 1. as step a. photo and follow steps:
1. Install the tire sensor to the valve.
2. Use the nylok screw and tight up with the tire sensor.
(Pls. 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 necessary to re-install the tire sensor, pls.
use the new nylok screw in order to prevent to re-use the
old ones.
d Put on the No. 2 tire sensor to the tire which marked
No.2, and set up the other 2 sensor in the same manner as
shows in the step c.
e Make sure there is no other liquid or dust beside of the
tire sensor.
f Follow the tire specification and inflate appropriate air to
the tire after finished the installation.
Balance the tires with the balance machine。
g
h Put back the tires to it’s corresponding position as shows
in the photograph on step a.
Turn on the ignition after the TPMS installation and start to monitoring the tire pressure/temperature
and car battery.
