1. External Tyre Pressure Monitoring System Introduction
The M2(TPMS M2) tyre pressure monitoring system is installed on the tyre rim of a vehicle
to monitor real-time tyre pressure and temperature and can transfer specific signals to the
receiver inside the vehicle via RF mode. In this way, drivers are aware of tyre conditions,
which can contribute to decreasing the rate of car accidents.
1.1 System Application
The M2(TPMS M2) tyre pressure monitor system must be installed according to the steps
indicated in the installation manual by a qualified operator so that it can be used accurately
and ensure the product warranty. This system is applicable to the tyres of common family
two-wheel vehicles. It can measure tyre pressure up to 60 psi (420 kpa). When the alert lights
or alert bells signal, drivers should slow down and park in a safe area, check the condition of
the tyre and have it repaired at a qualified repair company nearby.
Warnings
1. Applying sealant or special chemical fillings to the tyre may cause errors in the TPMS
or affect emitter function.
2. The tyre pressure monitor system (TPMS) is an affiliated piece of equipment for
vehicle safety. Drivers should always make routine inspections of tyre tread and tyre
condition.
3. This system transfers wireless signals; therefore, in specific circumstances, signals may
be weakened or blocked due to interference factors, incorrect operating or
inappropriate installation. We suggest choosing electronic products that comply with
requirements related to vehicle safety.
4. Drivers are supposed to maintain good driving habits and enact routine maintenance
of all key systems, which can help to reduce fuel consumption.
Drivers are supposed to make routine inspections and replace tyre valves yearly, in case of
leaking or other problems.

3.4 Press/Temp Unit Switch
- Pressure unit: psi, bar
- Temp unit: ℃, ℉
-When the pressure unit is displayed on the receiver, press Mode for three
seconds and switch to pressure unit (psi -> bar).
-When temp unit is displayed on the receiver, press Mode for three seconds
and switch to temperature unit (℃ -> ℉).
4. Factory Default Settings
Turn on the system and press the Set button of the receiver for three
seconds; you will see the front wheel tyre pressure setting
displayed.
Set tyre pressure to factory default tyre pressure: 35 psi (35 psi=2.4
bar).
Set tyre temperature to factory default tyre temperature: 80℃
(80℃=176℉).
(Note: please refer to standard factory default and set values)
a. 1F front wheel tyre pressure settings
Picture on the right side displayed on the receiver; factory default
tyre pressure is 35 psi, with a green light on.
If you do not want to reset, press the Set button and enter rear wheel
standard tyre pressure settings.
Press the Mode button on the receiver to adjust standard tyre
pressure; each press of the Mode button will add
1 psi to it.

8
Adjustable range is 27~50 psi. When higher than 50 psi, settings
will revert to 27 psi and cycle.
(Note: for the bar unit, 0.1 bar will be added; range is 1.9~3.5 bar).
After setting front wheel standard tyre pressure, press the Set
button and enter front wheel standard tyre pressure settings.
b. 2R rear wheel tyre pressure value settings
Picture on the right side displayed on the receiver; factory default
tyre pressure is 35 psi, with a green light on.
If you do not wish to reset, press the Set button and enter rear wheel
standard tyre pressure settings.
Press the Mode button on the receiver to adjust standard tyre
pressure; each press of the Mode button will add 1 psi.
Adjustable range is 27~50 psi. When 50 psi is exceeded, it will
revert to 27 psi and cycle.
c. After setting standard tyre pressure, press the Set button and enter the
high temp alert settings.
D. High temp alert settings
On the receiver, four groups of tyre temp are displayed at a factory
default value of 80℃, with lights green.
If you wish to retain the default settings, press the Set button to
finish the high temp alert value settings.

9
Press the Mode button on the receiver and adjust high temp alert
value settings. Each press of the Mode button will add 1℃.
Adjustable range is 60~99℃; a value higher than 99℃ will
automatically revert to 60℃and circulate settings.
(Note: for ℉ unit, each press will add 1℉; adjustable range is
140~210 ℉)
f. When finished setting high temp alert value, press the Set button
and the system will be active and in display mode.
