5. Setup

5.1 Charging the Monitor

Before first use, fully charge the TPMS monitor using the provided USB cable. Connect the cable to the monitor's USB port and a 5V USB power source.
The monitor also features a solar panel for continuous charging when exposed to sunlight. Place the monitor on your dashboard where it can receive direct sunlight.

5.2 Sensor Installation

The external sensors are designed for quick and easy installation, typically within 15 minutes. Each sensor is numbered (1-6) to correspond to specific tire positions.

Identify the correct tire for each numbered sensor (e.g., 1 for front left, 2 for front right, etc., as per your vehicle's configuration or the diagram below).
Unscrew the original valve cap from the tire valve.
Screw the corresponding numbered sensor onto the tire valve stem. Ensure it is tightened securely to prevent air leaks.
Repeat for all 6 tires.

5.3 Monitor Placement

Place the monitor on your vehicle's dashboard using the provided anti-slip mat. Ensure it is in a position that allows for clear visibility while driving and optimal solar charging.

6. Operating Instructions

6.1 Powering On/Off

The monitor typically powers on automatically when it detects vibration (e.g., when the vehicle starts moving) or when a button is pressed.
To manually power off, press and hold the power button (usually 'M' or a dedicated power icon) for a few seconds.

6.2 Display Information

The LCD screen displays real-time data for each tire, including:

Tire Pressure (in PSI or Bar)
Tire Temperature (in °C or °F)
Sensor Battery Status
Monitor Battery Status

6.3 Unit Switching

To switch between pressure units (PSI/Bar) or temperature units (°C/°F), refer to the monitor's buttons. Typically, a short press of the 'M' button or a dedicated unit button cycles through options. Consult your specific model's button layout for precise instructions.

6.4 Alarm Functions

The system will emit an audible and/or visual alarm under the following conditions:

High Pressure: Tire pressure exceeds the preset upper limit.
Low Pressure: Tire pressure drops below the preset lower limit.
Fast Leak: Rapid decrease in tire pressure.
High Temperature: Tire temperature exceeds the preset upper limit.
Low Sensor Battery: A sensor's battery is running low.

When an alarm occurs, identify the affected tire on the display and take appropriate action (e.g., check tire, inflate/deflate, replace sensor battery).

6.5 Tire Position Swap Function

This system supports tire position swapping without requiring physical sensor removal or re-pairing. If you rotate your tires, you can update the sensor positions through the monitor's menu. Refer to your monitor's specific menu options for this feature.

7. Maintenance

7.1 Charging

Ensure the monitor is regularly charged via solar power or USB to maintain optimal performance. A fully charged monitor ensures continuous monitoring even without direct sunlight.

7.2 Sensor Battery Replacement

The external sensors use replaceable button cell batteries (e.g., CR1632, specific type may vary by model). When a low sensor battery alarm is triggered, replace the battery promptly. To replace:

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

7.3 Cleaning

Wipe the monitor and sensors with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the device.

8. Troubleshooting

Problem	Possible Cause	Solution
Monitor not turning on	Low battery; Not detecting vibration	Charge the monitor via USB or place in direct sunlight. Press the power button to manually turn on.
No signal from sensor(s)	Sensor battery low/dead; Sensor not installed correctly; Interference	Check/replace sensor battery. Re-install sensor securely. Move monitor to a different position. Drive for a short distance to allow sensors to transmit.
Inaccurate pressure/temperature readings	Sensor not calibrated; Sensor faulty	Ensure sensors are correctly installed. Compare readings with a reliable tire gauge. If persistent, contact support.
Alarm sounds frequently	Preset limits too sensitive; Actual tire issue	Adjust high/low pressure and temperature alarm limits in the monitor settings. Check tires for actual issues (leaks, over/under inflation).

9. User Tips

Max Pressure: While the display shows readings up to 2.5 Bar (approx. 36 PSI), this system is designed for vehicles like Caravans, Trucks, and SUVs which often require higher pressures. The system is capable of monitoring pressures typical for these vehicle types, which can exceed 4.5 Bar (approx. 65 PSI). Always refer to your vehicle manufacturer's recommended tire pressure.
Sensor Inclusion: Each model variant (e.g., D-T6-6) includes both the display unit and the full set of 6 external sensors. You do not need to purchase sensors separately.
Initial Setup: Fully charge the monitor via USB before its first use to ensure it has enough power to operate and pair with sensors.
Regular Checks: Even with TPMS, it's good practice to visually inspect your tires regularly and manually check pressure periodically with a calibrated gauge.

10. Warranty and Support

For warranty information, technical support, or service inquiries, please contact the seller or manufacturer directly. Keep your purchase receipt as proof of purchase.
