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.

(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

6. Tyre Exchange Setting (external)
6.1 Tyre Exchange Setting –Method 1
Remove the two emitters from the tyre and also remove the two
batteries. When the tyre exchange setting is completed, put the
emitters back in order (according to the Chapter 2.1 installation
procedure).
6.2 Tyre Exchange Setting –Method 2
After exchanging tyres, press both the Set button and Mode button
for three seconds; the system will enter the tyre exchange setting
mode. Press the Mode button one more time and it will exit the tyre
exchange setting mode.
The number 1f being displayed on the receiver confirms that you can
do the front wheel setting now.
Setting in this order: NO.1F (front wheel) → NO.2R (rear wheel); finish
setting and it will exit setting mode and return to the normal
operation screen.
a. NO.1F setting (front wheel)
When the number 1F is displayed on the receiver you can effect
front wheel setting.
Please take out the batteries of the 1F (front wheel) emitter and
put them back right away. The setting is done when you hear
the “bee” alarm.

12
If you do not wish to reset, press the Set button; the system will
bypass setting automatically and enter the setting mode for No.
2 (rear wheel).
b. NO.2R setting (rear wheel)
When the number 2R is displayed on the receiver you can effect
rear wheel setting.
Please take out the batteries of the 2R (rear wheel) emitter and
put them back right away. The setting is done when you hear
the “bee” alert bell.
If you do not wish to reset, press the Set button; the system will bypass
setting automatically and return to normal operation.
7. Troubleshooting
1. E1 displayed on the screen.
This is a receiver initial value error caused by electromagnetic interference
in the environment. Please restart the receiver. If this does not solve the
problem within 10 minutes, please contact the local motorcycle workshop.
2. E2 displayed on the screen.
This indicates a low voltage for emitter batteries. Please replace emitter
batteries.
3. Is it normal that the results of traditional tyre pressure testers and this tyre
pressure monitor system are different?

13
Yes, it is normal. Traditional tyre pressure testers must be corrected
regularly for more accurate measurements. However, the error range of
electronic measurement is ±1 psi and as such, this TPMS is more accurate
than traditional tyre pressure testers.
4. Will the emitter stop working when the power is off?
Yes. The driver can tell from the receiver which emitter is powered off. If
you are using an external tyre pressure monitor, buy a CR1632 battery to
replace the old one, reset the values and it should return to normal
operation.
5. Should I unload the emitter when exchanging tyres?
Please refer to Chapter 6:“Tyre Exchange Setting”.
6. Can I adjust tyre pressure or temperature set value?
This product comes with default pre-set values. If you have other setting
requirements you can adjust them according to the tyre’s characteristics.
8. When does TPMS start monitoring?
When the engine and vehicle runs, TPMS will start monitoring, making the
driver aware of tyre conditions.
