TIRE PRESSURE MONITORING SYSTEM, TPMS
Tire Pressure Monitoring Systems (TPMS) improves safety while driving. Once installed in your
vehicle, the system will automatically monitor your tires in real-time for pressure and temperature.
If any tire’s pressure and/or temperature appears abnormal, the system will, in real-time,
transmit signals to activate an alarm and show a digital figure to warn the driver of a problem. The
system aids safety, extend the tire life and help reduce fuel consumption.
NOTICE
FCC 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, and (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.
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
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.
Caution
The system is wireless RF product; therefore, it may not receive signal due to interference environment or
incorrect operating or installation. When the system continually cannot receive signal from one of the tire
sensor more than 20 minutes since the system be switched on, the system will show “ E2 ”. In this case, it
may cause by a RF interference environment and driver needs to drive the vehicle to other place. If the
display still cannot receive any correct signal from tire sensor, then, driver needs to find a nearby qualified
tire maintain service for checking and maintain. It may cause by a tire sensor damaged or battery power
consumption is low (the battery consumption will be lower than under normal using condition due to
sensors need to send warning signal continually to driver) . If the system continually cannot receive signal
from any sensors more than 20 minutes, the system might damaged and will show “E1”. Driver needs to
drive to other place (there might be a interference nearby) or send the system
to agent for repair.

Manual for Tire Pressure Monitoring Systems, TPMS

System Installation and Usage
The installation of TPMS requires the qualified personnel to operate according to the instruction manual
so that it can function properly and have the warranty.
Warranty does not cover damages due to improper installation or disassembly.
This system is only suitable for Pick-up tires. The standard tire pressure is 20psi-110psi.
The maximum pressure the sensor can read is 116 psi (gauge). This system is not suitable for iron rim.
※In order to prevent the air leaking issues, it is strongly suggested that the valve has to be checked or
replaced on a regular basis.
Reaction to Alerts
When an alert or warning is received, reduce vehicle’s speed and pull over to a safe location 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.
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.

WIRELESS TRANSMITTER SENSOR INSTALLATION
Step
Process
Image
1
Use a jack to raise the vehicle and place jack stands
underneath the vehicle for safety. Refer to vehicle owner’s
manual for full service advice. Seek the assistance of a
qualified motor mechanic if required.
2
Take off the tires and bleed the air. Then take off the air
valve of the tire from the wheel. (NOTE: You must change
the valve to TPMS valve). This part of the process will
normally require the service of a tire fitting service or
mechanic.
3
Recognize the number on each sensor (D) with position of
tire on the vehicle. (VERY IMPORTANT)
a. RF –1 = Right Front, No. 1
b. RR –2 = Right Rear, No. 2
c. LR –3 = Left Rear, No. 3
d. LF –4 = Left Frtong, No. 4
4
Set up the new TPMS special valve (E) in the wheel.
Use wrench to fix the valve, and then tighten nut to
40~45kgf-cm (4~4.5Nm).
5
Clean inside the tire to prevent the tire from damaging the
transmitter sensor.
6
Inflate the tires.
Balance the tire
a. Balance tires using a balance machine
b. A lead tire weight may need to be added for balancing.
c. Balance until the tire balance shows balance as “OK”

The steps above will require the assistance of a tire fitting
service or a mechanic. It is important that the wheels are
balanced after the fitting of the TPMS sensors in order to
ensure the safe operation of the tire when refitted to the
vehicle.
7
Set up the other three tires in the same manner.
8
Turn the ignition key of the vehicle until the power is
activated on the cigar lighter, this may be first or second
position depending on the car manufacturer. The in-car
display will be activated.
The function button of the display unit can be switched to
pressure or temperature depending on the customer’s
need.

SYSTEM OPERATION
After the system is installed, it will automatically monitor the tire pressure and temperature. Once
the ignition is turned on, and the vehicle is in motion, the display will show the real-time tire
pressure and temperature individually.
SYSTEM ALARM
The alarm system will start, if tire pressure is too low, and if tire temperature is too high, the alarm
system will start too, and tire pressure will show on display. If high tire temperature and low tire
pressure situation happen at the same time, the system will show low tire pressure at first and
then show tire temperature, both of tire pressure and temperature will show on the screen for six
seconds by turns.
The alarm will keep making sound till turning off alarm system or solving abnormal situation, and
below the manual will explain operation process.
SETTING
The driver can follow the steps to adjust the system of defaulted values.
【Notice】: The system has been pre-set with alert figures. If the driver wants to change the figure, then
follow the professional tire technician’s instruction.

RESET FOR TIRE CHANGE AND ROTATION
The rotation is necessary to prolong the tire lifetime. The system can be reset through the following
processes to ensure the transmitter sensor indicate the correct tire position on the display.
The product has the Orange Tire Orientation (OTO) technology.
The system will automatically reset the tire position by driving for a while after tire or sensor change,
which is time saving for the end user.
There are two modes if drivers would like to operate it manually.
Mode 1: Replace Four Sensors
Mode 2: Replace Single Sensors
Warning
1. Do not turn off the vehicle power during this process, otherwise the setting will be stopped. The
process will be started after the power is turned on again.
2. After the repositioning, check the display to see if it shows all the 4 tire pressures. If the system
doesn’t work normally, please follow the instructions and reset. (This time, enter Mode 2 to use
single sensor replaced.)
3. The OTO (Orange Tire Orientation) function of this product may be invalid due to different
vehicles, rim types, weather condition or other environmental factors.
