Solar Tire Pressure Monitoring System
Operating Instructions
Important: Always turn on the main unit before installing the sensor. The schematic diagram of this manual is for reference only; specific to the physical shall prevail.
I. Use the Installation Tutorial
- Turn on the unit: Long press the [power-symbol] button for 3 seconds to turn on the computer.
- Install anti-theft nut: (as shown in Figure a) Clockwise tighten the security nut to the very bottom of the tire valve.
- Install sensor: (as shown in Figure b) Tighten the sensor quickly clockwise. It is normal to have air leakage in the middle of the process, and there will be no air leakage after tightening the sensor.
- Lock anti-theft nut: (as shown in Figure c) Lock the sensor by tightening the anti-theft nut counter-clockwise with a tool wrench.

B. Description of Key Functions:
- [power-symbol]: USB charging port/receiver charging port. In standby mode, long press to switch on/off.
- M: Left button/switch menu to the left.
- Menu key/confirmation key: In standby mode, long press to enter the menu mode, select the parameters to be adjusted, short press 1 time to confirm.
- Right button: Switch menu to the right.
C. Temperature exceeds the set alarm value, will give the alarm broadcast. Press "M" to stop the broadcast.
Sleep mode: After the car is turned off, the display screen will automatically turn off within three minutes. When the car is started, the display screen will automatically turn on.

IV. Switching Units
a. Press and hold the [unit-switch-symbol] key for 6 seconds to switch the pressure and temperature unit automatically.
b. Automatic switching of pressure and temperature unit display interface:

Pressure unit: Psi / Temperature unit: °F
Psi/°F unit display interface
V. Replacement of Batteries
When the sensors are connected to the battery, remove/install the shells one by one; do not miss or remove/install at the same time; it can effectively avoid the sensors being installed in other tire positions due to misplaced shells. (Battery CR1632, working humidity requirement -20℃~70℃)
- Please prepare a nut wrench before disassembling the sensor. Rotate the nut clockwise to separate the nut from the sensor, and then remove the sensor counterclockwise.
- Use a wrench to unscrew the sensor top cover housing counterclockwise.
- Remove the old batteries from the battery clamps and do a good job of environmental protection classification and disposal.
- Distinguish between positive and negative positions (positive "+" facing up); install a new lithium battery CR1632.
- Screw on the upper cover of the sensor shell, and then use a wrench to tighten clockwise direction can be completed.
VI. Please Install the Sensor in the Correct Position
