1. Attention
Read through this guide before installing the product.
zInstall the monitor (receiver) inside the vehicle where it doesn’t affect
your driving.
zThe monitor should be well fixed to avoid falling off during driving.
zCheck if there is any air leakage after installing the sensors. (Spray
some soapy water on the valve, the bubble goes bigger if air leakage.)
zThe tire may blowout for high tire pressure, and higher fuel
consumption for lower tire pressure.
zThe product will monitor the tire pressure and temperature in real time,
but it does not prevent any traffic accidents. So it’s important to
choose high quality tire and ensure normal tire pressure.
zTo ensure your safety, pay attention to the traffic while checking the
reading of tire pressure and temperature especially during driving.
2. Installation Notice
zSensors and receiver are connected with wireless signals.
zDue to air expansion and contraction while the tire is moving, it’s
normal that the tire pressure will slightly increase while driving.
zA normal tire has a little bit leakage, this phenomena has no direct
relationship to the installation of this product.
zSuggestion: Install the monitor (receiver) and power it up before
installing the sensors.
z4 sensors had been matched with the monitor (receiver) ex-factory, so
basically you don’t need to match the sensors again.

5. Functions and Features
5.1 Main Functions
This product is mainly used for monitoring the pressure and temperature of
tires automatically while driving. It provides advance alert for dangerous
status, such as fast leakage, Low/High tire pressure and high tire
temperature.
A. Reduce Driving Risks
As reported, over 70% of fatal traffic accidents on highway are caused by tire
blowouts or insufficient tire pressure. But only few drivers check the tires
regularly. When the tire pressure is too low, it will affect lifetime of tire and
increase the possibility of tire blowout. If the tire pressure is too high, it will
reduce the grip power of the tire.
B. Reduce Fuel Consumption
A 9 PSI drop in the tire pressure will cause approximately 4% increase in fuel
consumption.
C. Prolong Lifetime of Tires
Generally, 25% over inflated will reduce the lifetime of tire by 15-20%. 25%
under inflated will reduce lifetime of tire by 30%. If tire temperature increases,
the intensity of tire will be lower and the lifetime of tire will reduce. When the

7
temperature is high than the limitation (usually less than 80℃), tire wear will
increase 2% for every 1℃increase
D. Real-time Monitoring Tire Pressure
The product can monitor the pressure and temperature any time, if there is
any abnormal status, an alert will be sent immediately.
5.2 Product Features
A. Graphic User Interface
With the user-friendly GUI design of this product, the driver can easily see
and know the conditions of the tires, especially tire pressure and temperature.
B. High Accuracy
With high-tech tire pressure detection, the accuracy can be ± 1 PSI.
C. Abnormal Status Alert
During driving, if the tire pressure gets lower or higher than the setting value,
or the tire encounters fast leakage, an alert will be sent immediately.
D. Lightweight Design of Sensor
The TPMS sensors will not affect the appearance of tire.
E. Real time monitoring
The product monitors the status of tire every 3 seconds.

the relative icon will be shown and the value will flash, the alarm will also turn
on together with the flashing red light. Press any button to turn off the alarm,
however, the flashing red light and icon will continue until the problem is
solved.
nHigh Pressure Alert

pressure value), the high pressure icon and data will flash, the audible alarm
will turn on together with the flashing red light (8-1-1)
(8-1-1)
oLow Pressure Alert
For example, when the pressure of left front tire is 2.0 BAR (lower than low
pressure value), the low pressure icon and data will flash, the audible alarm
will turn on together with the flashing red light (8-1-2)

9. Trouble Shooting Guide
nMonitor doesn’t display properly
A. Ensure the monitor is turned on.
B. Check the connection between cigarette lighter and adapter.
C. Ensure DC socket is connected.
D. If above treatment are unable solve the problem,please contact the
local dealer.
oMonitor doesn’t display tire status instantly.
A. Check whether there is any radar detector and packing sensor nearby,
if so separate the monitor for 20cm from them.
B. Check whether the monitor is nearby the power line or speaker, if so
please removes the monitor.
pSensor doesn’t transmit the data.
A. Make sure the sensor and monitor are in the limited distance of the
wireless connection.
B. Check whether the sensor has CR1632 lithium battery.
C. Check whether the battery direction is correct.
D. Check whether the sensor battery has no power, the battery might be
exhausted for long time operation and now need to replace a new
battery.
E. Please re-install the battery. Remove the battery for 10s then install
the battery again to reset the sensor.
F. Make sure that the sensors are not mixed with others. Each sensor
has an individual ID code, the monitor only indentify the sensors of
same set and can’t identify sensors from other providers.
G. If above treatment are unable solve the problem,please contact the
local dealer.
qNo any tire pressure alert

17
A. Ensure the sensor is installed
B. If it’s an external sensor, please screw the sensor in the air nozzle
firmly, because the sensor is not able to push up the cord of air nozzle,
it can’t detect the tire pressure.
rMonitor screen display wrong color
Check whether the temperature is too low in vehicle (lower than -70℃), when
the temperature return to normal level, it will display properly.
sMonitor screen update slow down
Check whether the temperature is too low in vehicle (lower than -20℃), when
the temperature return to normal, it will display properly.
tThe monitor don’t display tire data after rebooting
When the sensor detects change of tire pressure with more than 1PSI, the
sensor will transmit out the data. The data will be displayed when the vehicle
is running.
