Using the Receiver
1. Power On
After installing the receiver, press and hold the power button or plug in the USB cable to power on
the sensors. When powered on, the receiver will give out a “beep” before showing the tire pressure
values on the display. Initially, the display will show “- - “. This is normal. The tire pressure values
will be shown after the car has moved for 3 to 5 minutes. Alternatively, you can turn on the receiver
while installing the sensors at the workshop and the tire pressure and temperature will be
displayed on the receiver during the installation process.
2. Alarm Function
Leakage alarm
When the pressure of any tire drops by 0.2 bar or more during any transmission cycle, the
receiver will trigger a buzzer alarm and the pressure value for the affected tire will keep flashing
on the display.
The buzzer alarm can be stopped by pressing the power button or when the tire pressure stops
dropping.
High pressure alarm
When the pressure of any tire is 125% higher than the standard tire pressure at cold state during
any transmission cycle, the receiver will trigger a buzzer alarm and the pressure value for the
affected tire will keep flashing on the display.
The buzzer alarm can be stopped by pressing the power button or when the tire pressure is 0.1
bar lower than the alarm threshold. (Default high pressure alarm threshold: 3.0 bar)
*
Pressure alarm settings should be adjusted for different car models based on the car manual or after consulting a
workshop.
Low pressure alarm
When the pressure of any tire is 75% lower than the standard tire pressure at cold state during
any transmission cycle, the receiver will trigger a buzzer alarm and the pressure value for the
affected tire will keep flashing on the display.
The buzzer alarm can be stopped by pressing the power button or when the tire pressure is 0.1
bar lower than the alarm threshold. (Default low pressure alarm threshold: 1.8 bar)
*
Pressure alarm settings should be adjusted for different car models based on the car manual or after consulting a
workshop.
High temperature alarm
When the temperature of any tire exceeds the threshold during any transmission cycle, the
receiver will trigger a buzzer alarm and the temperature value for the affected tire will keep
flashing on the display.
The buzzer alarm can be stopped by pressing the power button or when the tire temperature is 1
℃ lower than the alarm threshold. (Default high temperature alarm threshold: 70 ℃)
Low battery alarm
When the remaining battery life of the receiver is less than 20%, the battery icon will flash.
3. Sleep Mode and Power Off
The receiver will enter sleep mode when there is no vibration and it does not receive any data from the
sensors for 5 minutes. It will turn on again when a vibration is felt while in sleep mode or when a USB
cable is plugged in. When the receiver is being turned on without a USB connection, it can be turned
off by pressing and holding the power button. When it is turned on with a USB connection, the
receiver will enter sleep mode when the power button is pressed and held.
