Introductions
Thank you for purchasing our TPMS Device Model No.
T501.
Adopting the Infineon solution, the TPMS device mainly
consists of 4 tire sensors modules and a 4 inches LCD
color screen brilliantly monitoring vehicle status such as
air pressure & tire temperature in real time.
Also a L-capacity rechargeable battery is inserted inside
the host (or we say the LCD screen) . And a high-efficient
solar panel is equipped as well. Moreover the integrated
circuit board built-in is designed for low power
consumption. With all 3 delicate elements above the
endurance of the device is up to 45 days which offers
profound assistance for long road trips.
Further, via our self-developed Android and iOS Apps
available in Google Play and App Store, you can connect

your phone with the TPMS device, monitoring and
controlling your vehicle more smartly.
Now please take some time to know the device well,
install it properly as per instructions below and commence
the fantastic experience.

Sensor’s Types
The TPMS Model No. T501 employs sensors on each
wheel, either internal or external, displaying real-time tire
pressures, temperature and etc. at each location monitored
whenever the vehicle is moving.
In regards to the External Sensor Module, it can be easily
mounted to the valve stems manually. And there’s no need
to adjust the tire’s dynamic balance due to sensor’s
negligible weight. Please refer to the picture of the
external sensors below.

While for the Internal Sensor Module, instead of the
original valve stem, is mounted on the inside of the rim.
And we highly recommend you that please bring the
device to a tire-repair workshop and let the professionals
do the exchange as it is being possible only with the tires
dismounted. Also the dynamic balance adjustment is
required since our internal sensor module has a certain
weight which makes some difference to pressure. Picture
of the internal sensors are as followings.

Installing and Setting Up
1. Connect the device to a power outlet and charge it
for at least 4 hours. Make sure the battery is fully
charged on first use. (Important: DC 5V)
2. Turn on the power switch on the back and screen
will be lit up.
3. External Sensors: Mount the sensor modules to the
valve stems one by one, meantime check the data
(air pressure value / temperature value) showing on
the corresponding position of the display screen is
normal or not.
Internal Sensors: Please take device to a tire-repair
workshop and let professionals
1Dismount tires.
2Replace the valve stems with sensor modules.
3Bleed and fill the tire one by one.
4At the same time observe the data (air pressure
value / temperature value) showed on the
corresponding position of the display screen is

-10 -
normal or not.
4. Start the car and run at a speed of no less than
30Km/H for 10 minutes. The whole set-up process is
complete.
Proper Display
A real-time and accurate display of tire air pressure value /
temperature value / solar panel working status / battery
capacity, etc.
Alarm and Warning
TPMS T501 monitors the real-time status of tires when
vehicle is moving and will warn driver timely if there is
any abnormal situation.

-11 -
Low Pressure Warning: When the tire pressure is lower
than the set value, the corresponding tire icon as well as
the pressure value will keep flashing and a buzzer sound
will pop out.
High Pressure Warning: When the tire pressure is higher
than the set value, the corresponding tire icon and the
pressure value will keep flashing and a buzzer sound will
pop out.

-12 -
High Temperature Warning: When the tire temperature
is higher than the set value, the corresponding tire icon and
the temperature value will keep flashing and a buzzer
sound will pop out.
RF Receive Data Failure Warning: it may happens that
the sensor is damaged because of the improper installation
or usage the sensor. In a set time (System setting value is
15 minutes) the host will fail to receive the radio
frequency transmitted from the damaged tire sensor. Under
this circumstance the icon of the corresponding tire, the
tire pressure value and the temperature value will be
blinking, which alerts the driver to the emergency

-13 -
situation.
Sensor Low Battery Warning: A button cell is inserted in
each tire sensor. Normally the cell life of the external
sensors can last for 2 - 3 years, while 4 - 5 years for the
internal sensors (depending on the actual usage conditions).
When system detects a low-battery status the
corresponding tire icon as well as low-battery indicator
will be lit up.

-14 -
Low Battery Warning for Rechargeable Battery: The
host (main device) is equipped with a high-temperature
rechargeable polymer battery. When the system detects
that the battery is low, the following alarm interface will
show up. Then the host shall be charged promptly.

System Setting: Tire High Temperature Warning
System Setting: Boot Sensitivity
Owing to the inserted G-sensor detecting the vehicle’s
vibration intensity all the time, the device is programmed
to turn itself on automatically once the ignition is on. This
is what we call “the boot sensitivity of the device”. In the
setting menu the value of “Boot Sensitivity” can be edited,
saved and loaded. The bigger the boot sensitivity value is,
the more sensitive the device will be.

System Setting: Auto Shutdown (unit:Second)
The TPMS is also programmed to shift to “sleeping mode”
i.e. be shut down automatically after a set time
(unit:Second) when the vehicle is completely stationary
and there is no vibration signal being detected any more.
System Setting: Replacement of the Damaged Sensor

In order to prolong the cell life, the sensor will stop
transmitting RF signals when there is no change in tire
pressure or temperature. RF Reception Interval will be set
on this interface (unit:Minute)
