I I . The safety significance of the tire pressure monitoring
system
1. Tires are the most important part of the car, which means significant to
the safety of driving, dues to too much terrible traffic accidents caused by
its problem. As a matter of fact, to keep standard tire pressure and timely
detection of tire leaks is the key to safe driving. For the time being, fix
direct tire pressure monitoring system is the major mature way monitor the
tire pressure.
2. This product is a direct tire pressure monitoring system, it can be
real-time monitoring of tire pressure and temperature status, in time give
out alarm once abnormal situation happen. You needn’t check by eyesight
or percussion tires or other unscientific methods to determine whether the
tire is leak. Don’t worry about the pressure or temperature is too high to be
nervous.
Remark:
Always keep the standard tire pressure, safe driving, not only can prevent
puncture, but also reduce fuel consumption and extend tire life.
III. The working principle of tire pressure monitoring
system
The Tire Pressure Monitoring System (TPMS) is designed to monitor the
internal pressure and temperature of the tire by means of a sensor
mounted on the tire and to transmit the collected data to the driver in the
cab Of the receiver. TPMS can monitor the vehicle tire pressure and
temperature information in real time. Alarm give out as long as low

pressure, high pressure, air leakage, high temperature and other abnormal
situation, to remind the driver who need to take corresponding effective
measures to play a role in safety assistance to achieve car travel more
Safe, reliable, comfortable, and economical.
IV.Product profile:
The TPMS/HUD intelligent integrated machine extends the concept of
combining the HUD car head-up display function with the two functions of
the car slope meter, greatly improving the safety escort level of the product
to the user.
The TPMS/HUD intelligent integrated machine acquires data from the
satellite through the GPS/Beidou dual-channel module. The dual-channel
module has the advantages of strong star search capability and stable
signal. The TPMS/HUD intelligent integrated machine is used in all models
on the market.
With TPMS/HUD intelligent all-in-one machine, you can drive without
bowing, pay attention to the vehicle dynamics at any time, and you can
also see the status of the vehicle tires. The TPMS/HUD intelligent
all-in-one machine uses LCD color display. The effect is dazzling and clear,
and the vision is clear at a glance. TPMS/ HUD intelligent all-in-one

* Press the “M” key once again, and the display interface 4 is flashing.(as
shown in the following figure)
* Then press "back key" and "forward key" simultaneously for 5 seconds to
enter the tire matching interface.(as shown in the following figure)
* Then twist the tire valve cap that is installed with the sensor, keep the air
pressure between 0.7-2.5Bar, and inflate or deflate the tire. The number in
the lower row of the display will show that the pair has been paired
(corresponding The number represents: 0 for FL, 1 for FR, 2 for RL, and 3
for RR) (as shown in the figure below, it means that the pair is on the FR
right front wheel, long press "M" key to save)

XIV. Introduction to the function of mainframe
(Note: Only press the “M” button in the tire pressure mode to enter the
setting interface.)
1.Clock setting
*Mainframe interface In the tire pressure mode, long press the "M" key to
enter the setting mode, press the left key twice to enter the interface (as
shown in the following figure). The default time of the system is GMT
(Greenwich Mean Time, 0 time zone). If there is a time difference in local
time, please follow the steps below:
* The time unit of this interface is min. Press the “M” key for the first time,
the ones flash, use the left and right keys to adjust the ones; the second
press the “M” key, the ten digits flash, and the left and right keys adjust Ten
digits; the third time press the "M" key, the hundred digits flash, and the left
and right keys are used to adjust the hundred digits;
*Setting is completed, long press "M" key to save and exit. The display
time in HUD mode is GMT plus the current setting value.
For example, Beijing is the East Eight District (one hour in a time zone), 8

hours (480 minutes) faster than Greenwich Mean Time (GMT), and should
be set to 480. US Eastern Time is West 5th District, 5 hours slower than
Greenwich Mean Time (GMT), (300 minutes), should be set to -300.
2.Unit switching setting
*The mainframe interface in the tire pressure mode, long press the "M" key
directly into the MPH / KMH unit switching interface (as shown in the
following figure), and then press the "M" key once, at this time set the
interface PSI or BAR To flash, press “Forward or Back” to select the unit to
be set, and press “M” key to save the setting (Explanation: In PSI unit
mode, the speed unit defaults to MPH inch, the temperature unit defaults
to °F Fahrenheit. In the BAR unit mode, the vehicle speed unit defaults to
KM/H metric, and the temperature unit defaults to °C degrees Celsius.)
3.Low pressure setting of tire
*Mainframe interface In the tire pressure mode, long press the “M” key to
enter the air pressure setting interface, press the second “forward key” to
enter the tire low pressure alarm setting interface, as shown in the
following figure and press “forward key or backward” The key "sets the tire

low pressure to "1.8 Bar", the normal tire normal pressure is "2.0-2.8 Bar"
and the low air pressure cannot be lower than "1.8 Bar".
4. High air pressure setting of the tire
Mainframe interface In the tire pressure mode, long press the "M" key,
press the "forward key" once to enter the tire high pressure alarm setting
interface, (as shown in the following figure) and press the "forward key or
back key" to the tire high pressure Set to "3.0 Bar", the normal tire
pressure is "2.0-2.8Bar" and the high pressure cannot exceed "3.0 Bar".

pressure to "75 ° C", the normal tire normal temperature is "negative 5 ° C -
positive 75 ° C" temperature value can not exceed "75 ° C".

6. High voltage alarm
When the receiving mainframe detects that a certain tire pressure value
has changed and the tire pressure value exceeds the set "3.00Bar" air
pressure value, the mainframe alarm icon " " will be illuminated,
The tire data value does not flash at the same time, and the alarm of
“di, di, di...” is not issued to indicate that the tire has failed. (as shown in the

following figure)
7. Low voltage alarm and fast air leakage alarm
When the receiving mainframe detects that a certain tire pressure value
has changed, but does not lower the set air pressure value, the receiving
mainframe alarm icon " " will light up, and the tire data value
flashes at the same time. And issue a "di, di..." alarm warning; if the tire
pressure value is lower than the "1.80Bar" air pressure value, the
mainframe alarm icon " " will be illuminated, tire data value does
not flash at the same time, and the alarm of "di, di, di..." is not issued to
indicate that the tire has failed. (as shown in the following figure)
8. High temperature alarm
When the receiving mainframe detects that a certain tire temperature
exceeds the set temperature value, the mainframe alarm icon " " will
be illuminated, and the” ” tire data value will not flash at the same
time, not the segment. An alarm "di, di, di..." is issued to indicate that the
tire is hot. (as shown in the following figure)
9.No signal alarm
During the driving process, when the mainframe is received for 10 minutes
without receiving the signal transmitted by the sensor, the mainframe
