Thank you choosing the Britpart Tyre Pressure Monitoring System.
This system is an advanced monitoring & a ert system of tyre conditions. It monitors tyre pressure and temperature and re ays the
state of each tyre to a disp ay unit. When any abnorma ities are detected, the system wi disp ay the status of the affected tyre and
sound an a arm to ensure you take action to remedy the prob em. Keeping your tyres in good condition at the right pressure can
extend the ife of your tyres and reduce fue consumption.
P ease read this manua carefu y before using our product.

This system app ies to 4 whee ed vehic es with meridian tyre (vacuum tyre) and co d tyre pressure (22ºC) ower than 2.8 bar
(280KPa/40.6psi/2.86*104kgf/m2). It shou d be insta ed by a qua ified professiona according to this manua . This system is an
e ectronic device that measures and disp ays the inside air pressure and temperature of the tyres and gives a warning signa when
an abnorma ity is detected. The system has no contro ing function so the driver shou d rectify and detected prob ems as soon as
possib e. The performance of the sensors cou d be affected by chemica materia s. Preset pressure from the manufacturer is 2.40
Bar (240KPa/34.8psi/2.45*104kgf/m2). P ease set it to your vehic es recommended pressures after the initia insta ation (see
detai s on page 14). This system is to be used as a monitoring aid on y and Britpart wi take no responsibi ity after the kit is insta ed
and the user must ensure tyres are inf ated to the vehic e manufacturers recommendations.

System Operation
The system enters into working status after insta ation. With ACC ON the system starts se f-test then disp ays the inside pressure
and temperature of each tyre for 2 seconds. If a tyres are in good condition, the disp ay wi go off automatica y, the status
indicator (LED) turns green. Otherwise the buzzer wi sound 3 times with the indicator in orange or red and the disp ay wi show the
re evant information, the buzzer wi sound 3 times every 3 minutes unti the prob em is rectified.
Press SCAN to read the data of each tyre.
Press SET 3 seconds to convert the temperature units - ºC to ºF
