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.

A. Bracket Mounting
Mount the holder on the backside of
monitor (receiver) and tighten the
screws.
Note:
z4 sensors had been matched with
the monitor (receiver) ex-factory,
so basically you don’t need to
match the sensors again.
zPlease use the assigned screws
to avoid damage to the product
The base of the holder can be
mounted on top of monitor so you
can stick it on the windshield or
placed on dashboard

B. Cigarette Lighter Mounting (factory default mounting)
Mount the holder on the backside of
monitor (receiver) and tighten the
screws
Note:
Please use the assigned screws to

Insert the cigarette lighter
connector into the holder and
tighten the screws

Suggestion: Install the monitor
(receiver) and power it up before
installing the sensors.
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.
