2. What's in the Box
- Tymate TPMS Display Monitor
- 6 External TPMS Sensors
- Signal Repeater (for extended range)
- USB Type-C Charging Cable
- User Guide
- Service Pack (includes sensor nuts, wrench, and spare O-rings)
3. Key Features
- Dual Charging Options: The display unit can be charged via its integrated solar panel for continuous power under sunlight or through a USB Type-C port when solar charging is not feasible.
- Real-time Monitoring: Provides simultaneous display of tire pressure and temperature for all 6 sensors, allowing for immediate awareness of tire conditions.
- Five Alarm Modes: Alerts users to critical tire conditions including fast leak detection, high-pressure, low-pressure, high-temperature, and sensor low voltage warnings.
- Easy Setup: The system automatically sets the current tire pressure as the reference point upon pairing, simplifying the configuration of alarm thresholds. Alarm range is adjustable from +25% PSI to -15% PSI of the reference pressure.
- Extended Signal Range: Includes a signal repeater to ensure stable connectivity and extend the sensing range beyond 50 feet, crucial for longer RVs and trailers.
- Durable Sensors: Sensors are designed for low power consumption with a battery life of up to 2 years. They are compact, lightweight, and resistant to dust, water, wind, and snow. Pressure accuracy is within 3 PSI.
- Upgraded Color LCD Display: Features an intelligent color LCD screen that automatically adjusts backlighting for optimal visibility in various lighting conditions.
- Energy-Saving Mode: The display enters a power-saving mode after 10 minutes of vehicle inactivity (without charging) to conserve battery. It reactivates with any key press or vibration.

4. Setup Instructions
4.1 Initial Charging of Display Unit
- Before first use, fully charge the display unit using the provided USB Type-C cable. Connect the cable to the display unit and a standard USB power adapter (not included).
- Once charged, the display can maintain its battery level through its solar panel when exposed to sunlight on your dashboard.
4.2 Sensor Installation
- Identify each sensor by its marking (e.g., LF for Left Front, LR for Left Rear, RF for Right Front, RR for Right Rear, etc., for 6-sensor systems).
- Remove the original valve stem cap from the corresponding tire.
- Screw the Tymate sensor onto the valve stem quickly to minimize air loss. Ensure it is tightened securely.
- For added security and anti-theft, you may use the provided hexagonal nuts and wrench. First, screw the nut onto the valve stem, then screw on the sensor. Tighten the nut against the sensor using the wrench.
4.3 System Pairing and Calibration
The Tymate M7-3 system is designed for easy setup. Upon initial power-on and sensor installation, the system will automatically detect and pair with the sensors. The display will show the current tire pressure and temperature readings.
- The system automatically sets the current tire pressure as the reference point for alarm thresholds.
- You can adjust alarm thresholds (high/low pressure, high temperature) through the display unit's settings if needed. Refer to the detailed User Guide for specific menu navigation.
5. Operating Instructions
5.1 Display Information
The color LCD display provides clear, real-time data for all monitored tires. Information typically includes:
- Tire Pressure (in PSI or BAR)
- Tire Temperature (in °F or °C)
- Sensor Battery Status
- Display Unit Battery Status
- Tire Position Indicator (e.g., LF, LR, RF, RR)

5.2 Alarm Functions
When a tire condition deviates from the set thresholds, the system will trigger an audible and visual alarm. The display will highlight the affected tire and indicate the specific alarm type.
- Fast Leak Alarm: Alerts immediately to rapid pressure loss.
- High/Low Pressure Alarm: Activates if pressure exceeds or falls below the set limits.
- High Temperature Alarm: Warns if tire temperature becomes excessively high.
- Sensor Low Voltage Alarm: Indicates that a sensor's battery is low and requires replacement.
5.3 Energy-Saving Mode
To conserve power, the display unit will automatically enter an energy-saving mode if the vehicle remains stationary for 10 minutes without charging. In this mode, the display will turn off, and no sensor data will be received.
To reactivate the system, simply press any button on the display unit or cause the unit to vibrate (e.g., by starting the vehicle or moving the display).
6. Maintenance
6.1 Sensor Battery Replacement
The external sensors are designed with long-lasting batteries (up to 2 years). When a sensor low voltage alarm is triggered, the sensor battery needs to be replaced. Refer to the detailed User Guide for instructions on how to open the sensor and replace the battery.
6.2 General Care
- Keep the display unit's solar panel clean and unobstructed to ensure efficient solar charging.
- Wipe the display unit and sensors with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Ensure sensors are securely tightened on valve stems to prevent air leaks and loss.
- Regularly inspect your tires for overall condition, even with the TPMS installed. The TPMS monitors pressure and temperature but cannot detect physical damage or instantaneous changes from sharp objects.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Intermittent data display | Interference from other electronic devices; signal range issue. | Move the display unit away from potential interference sources. Ensure the signal repeater is properly installed and positioned to extend the range, especially for long vehicles. |
| Display not turning on or holding charge | Insufficient charging; battery issue. | Ensure the display unit is fully charged via USB-C. Place the unit in direct sunlight for solar charging. If the issue persists, contact customer support. |
| Sensor not reporting data | Sensor battery low/dead; sensor not properly installed; sensor damaged. | Check for a sensor low voltage alarm and replace the battery if necessary. Re-install the sensor, ensuring it is tightly screwed on. If the problem persists, the sensor may need replacement. |
| Display numbers difficult to see in bright sunlight | Automatic backlighting adjustment limitations. | While the display adjusts automatically, extreme glare can affect visibility. Try repositioning the display unit slightly to reduce direct glare. |
| TPMS cannot prevent tire blowouts from sharp objects. | System limitation. | The TPMS monitors pressure and temperature but cannot prevent punctures from sharp objects or monitor instantaneous changes. Regular visual tire inspections are still necessary. |
