Precautions
1. Please choose the installation location carefully so that the LCD monitor
will not interfere driver when driving.
i. Please make sure LCD monitor firmly fixed to the front windshield or
dashboard.
ii. When read through tire pressure figures from LCD monitor, please
also take care of driving safety.
2. Please make sure the LCD display can receive signals from all tire
pressure sensors.
3. TPMS CRX-1002 has unique anti-theft tool to prevent sensor being
stolen. You can decide whether install or not.
4. Please double confirm if sensors are fitted tightly. If necessary, please
spreading detergent water on the valve stem to check any air leakage.
5. If tire pressure is getting down or dropping quickly, please stop car
immediately to find out if tire is deflated or another other problem is
happening.
6. The monitor will automatically make connections in whole system
when car starts to run. It is normal that some tire pressure figures
might not be updated immediately due to there is no change of tire
pressure in those tires.
7. TPMS CRX-1002/1003 has mechanism to avoid interfering /
being interfered with other signals.
8. Many environmental factors cause tire pressure rise and down as well.
For example, hot weather or warm tire will lead rising tire pressure.
9. It is natural that tire pressure will decrease by days but not caused by

5
the installation of tire pressure monitoring system. TPMS
CRX-1002/1003 can response with its real figure of pressure.
10.Please don’t mix your sensor with other systems’, as each system has
its separate unique identified number of sensor, or the mixed sensor
won’t activate.
11.If you have any questions or problems concerning your unit that are
not covered in this manual, please consult your nearest TPMS
CRX-1002/1003 dealer.
The Main Purpose
The Tire Pressure Monitoring System (TPMS) is an efficient and
effective solution to many of current automotive safety problems. TPMS
will help prevent driving on deflated tires and reduce fuel consumption.
There are benefits here:
zImproves ride performance and handling
Tire pressure leads to driving condition a lot.
zDecreases chance of tire blowout
It is very critical to keep tire pressure in a good condition when driving,
especially when buses, trucks are carrying people life and dangerous
materials such as poisonous substances, oil, etc.
zReduces labour of tire pressure inspections
Multi-wheel trucks cause time consuming in human inspection in tire
pressure. Goes without saying that no chance to monitor tire pressure
when running. The system can have a very clear picture of tire
pressure status among all tires.

6
zNot adds much maintenance cost
Advanced designs to give the best convenience to all drivers by
wireless/ cordless design, external sensors, etc.
zLess downtime
Real time monitoring gives you highly control of your tire pressure and
temperature and avoid unexpected accidents caused from abnormal
tire pressure and temperature.
zReduces fuel expense
Fuel efficiency is reduced by one percent for every 3 PSI. of under
inflation. It is for sure that tire pressure is also one of important factors
to save gas consumption.
zExtends tire life
Research finds that running tires 20% under – inflation can reduce tire
life by up to 50%. It is crucial to keep tire pressure at a right level (right
tire pressure figures for each tire normally suggested by your car
manufacturer)
zIncreases return on investment
Concludes advantages mentioned above, by taking care of tire
pressure with simple Tire Pressure Monitor System, gains are much
more than what you expect.
