3. Configuració i instal·lació

3.1 Instal·lació del sensor

The external sensors are designed for easy installation without professional assistance. Follow these steps:

1. Ensure the TPMS monitor is turned on.
2. Unscrew the original valve cap from each tire.
3. Screw on the anti-theft nut (included in the toolkit) onto the valve stem.
4. Screw the corresponding sensor onto the valve stem. Ensure it is tightened securely to prevent air leakage.
5. Tighten the anti-theft nut against the sensor using the provided spanner.
6. Repeat for all 6 tires. The system will automatically recognize the sensors and display readings.

Nota: For the first installation, it is crucial to turn on the monitor first, then install the sensors. This allows the system to recognize changes in tire pressure and activate correctly.

3.2 Instal·lació del monitor

The monitor offers two primary installation methods:

3.2.1 Cigarette Lighter Installation

The monitor can be directly plugged into your vehicle's cigarette lighter port using the provided cigarette power line and bracket. The screen angle can be adjusted for optimal viewing.

4. Instruccions de funcionament

4.1 Mostra informació

The LCD screen displays real-time tire pressure and temperature for all 6 tires. It supports two pressure units ("PSI", "BAR") and two temperature units ("℃", "℉"). The display also shows an alarm icon when an abnormal condition is detected.

4.2 Alarm Modes and Settings

The U903-6 TPMS provides 5 distinct alarm modes to alert you to potential tire issues. When an alarm is triggered, the monitor provides both visual (flashing icon and value) and audible alerts. Pressing any button will turn off the audible alarm, but the icon will continue to flash until the problem is resolved.

• High Tire Pressure Alert: Triggered when tire pressure exceeds the user-defined high-pressure preset value.
• Low Tire Pressure Alert: Triggered when tire pressure falls below the user-defined low-pressure preset value.
• High Tire Temperature Alert: Triggered when tire temperature reaches or exceeds the user-defined high-temperature preset value.
• Quick Air Leakage Alert: Detects rapid air loss from a tire.
• Alerta de bateria baixa del sensor: Indicates that a sensor's battery level is low and requires attention.

Users can customize the high and low-pressure alarm values for each of the three axles (for 6-wheel mode) to match specific vehicle requirements. Factory default settings are: High-pressure alarm: 116 PSI, Low-pressure alarm: 58 PSI, High-temperature alarm: 149℉ (65℃).

5. Manteniment

To ensure the longevity and optimal performance of your B-Qtech TPMS, consider the following maintenance points:

• Cura del sensor: The sensors are designed to be waterproof and dust-proof. Periodically check them for any physical damage or blockages.
• Substitució de la bateria: When the sensor low battery alert is triggered, replace the sensor battery promptly. Refer to the detailed instructions in the full user manual for battery replacement procedures.
• Neteja del monitor: Clean the monitor screen and casinNetegeu amb un drap suau i sec. Eviteu utilitzar productes de neteja o dissolvents abrasius.
• Emmagatzematge: If storing the system for an extended period, ensure the monitor and sensors are kept in a cool, dry place.

6. Solució De Problemes

This section addresses common issues you might encounter with your TPMS. For more detailed troubleshooting, please refer to the comprehensive user manual (PDF) provided with your product.

6.1 Monitor Not Displaying Tire Pressure Reading After Installation

Solució: For the initial setup, first turn on the monitor, and then install the sensors. The sensors require a change in tire pressure to activate and transmit data to the monitor. Ensure sensors are securely tightened.

6.2 Difficulty Setting Different Alarm Values for Different Vehicles

Solució: The system allows for user-defined alarm value settings. The pressure of different vehicle tires can vary, and the alarm value range supports customization. Refer to the "Alarm Modes and Settings" section in this manual or the full PDF manual for detailed steps on how to adjust these values.

6.3 Using a 6-Sensor System on a 4-Wheel Vehicle

Solució: The 6-wheel and 4-wheel modes can be switched on the U903-6 system. Please refer to the instruction manual for the specific steps to switch between these modes.
