5. Setup and Installation

5.1 Mounting the Display Unit

1. Attach the mounting bracket to a suitable location on your motorcycle's handlebars or dashboard, ensuring it does not obstruct your view or controls.
2. Secure the bracket firmly using the provided screws or clamps.
3. Slide the TPMS display unit onto the mounting bracket until it clicks into place. Adjust the viewing angle as needed.

5.2 Installing External Sensors

The sensors are labeled "FW" for the front wheel and "RW" for the rear wheel. Ensure correct placement.

1. Unscrew the original valve cap from your tire valve stem.
2. Thread one of the provided hex nuts onto the valve stem.
3. Screw the corresponding sensor (FW for front, RW for rear) onto the valve stem until it is hand-tight.
4. Using the provided sensor wrench, tighten the hex nut against the sensor to secure it and prevent theft.
5. Repeat for the other tire.

5.3 Wiring the Display Unit

1. Connect the red wire from the display unit's power cable to your motorcycle's 12V positive power source (e.g., ignition switch, battery positive terminal).
2. Connect the black wire to a suitable ground point on your motorcycle chassis or battery negative terminal.
3. Ensure all connections are secure and insulated to prevent short circuits.

6. Operating Instructions

6.1 Powering On/Off

• The display unit will power on automatically when the motorcycle's ignition is turned on, provided it is correctly wired.
• To manually power on/off, press and hold the power button on the display unit.

6.2 Understanding Display Readings

The LCD screen displays real-time information:

• Tire Pressure: Shown for both front and rear tires (e.g., 2.5 BAR or 36 PSI).
• Tire Temperature: Shown for both front and rear tires (e.g., 25°C or 77°F).
• Battery Voltage: Displays the motorcycle's battery voltage (e.g., 12.5V).
• Battery Indicator: Shows the battery level of the display unit itself.

6.3 Alarm Functions

The system will emit a loud audible alarm and display a visual warning under the following conditions:

• High/Low Tire Pressure: If pressure exceeds or falls below preset thresholds.
• High Tire Temperature: If temperature exceeds a safe limit.
• Sensor Battery Low: Indicates that a sensor battery needs replacement.
• Signal Loss: If communication with a sensor is lost.

6.4 QC 3.0 Charging Port

The display unit features a QC 3.0 fast charging port, typically located on the side. This allows you to charge compatible devices such as smartphones or cameras while riding.

6.5 Unit Selection

Refer to the display unit's specific button functions (usually a 'SET' or 'M' button) to cycle through and select desired units for pressure (BAR/PSI) and temperature (°C/°F). Consult the quick start guide included with your product for exact button sequences.

7. Maintenance

7.1 Sensor Battery Replacement

The external sensors use CR1632 button batteries. When the display indicates a low sensor battery, replace it as follows:

1. Unscrew the sensor from the tire valve stem.
2. Carefully open the sensor casing (usually by twisting or prying gently).
3. Remove the old CR1632 battery and insert a new one, ensuring correct polarity.
4. Close the sensor casing securely and re-install it on the tire valve stem.

7.2 Cleaning

Wipe the display unit and sensors with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the charging port cover is closed when not in use to maintain water resistance.

7.3 Connection Checks

Periodically check all wiring connections to the motorcycle's power source to ensure they remain secure and free from corrosion.
