Setup
1. Charging the Device
Before first use, ensure your T5 Smart Wristband is fully charged. The device features a convenient USB charging method.
- Carefully take the main unit out of the wristband.
- Insert the charging head of the main unit directly into a standard USB port (e.g., on a computer, power adapter, or power bank).
- The LED display will indicate charging status. A full charge provides approximately 40 days of standby time.


2. Initial Settings
After charging, you can manually set the time, date, height, and weight directly on the bracelet. Refer to the operating instructions for navigation.
Operating Instructions
1. Basic Navigation
The T5 Smart Wristband typically operates with a single touch-sensitive area on the display. Tap or long-press to cycle through different display modes and access settings.
2. Activity Tracking
- Pedometer: The high-sensitivity 3D acceleration sensor accurately counts your steps.
- Calorie & Distance: View your burned calories and distance covered directly on the bracelet's display.
- Motion Data Memory: The bracelet stores 24 hours of motion data, which automatically resets at midnight to begin a new day's tracking.
3. Time and Date
The wristband displays the current time and date. These can be manually set as part of the initial setup.
4. Silent Alarm Clock
You can set a silent vibration alarm directly on the bracelet without needing a separate app. Consult the device's interface for alarm setting options.
5. Heart Rate Monitoring
The T5 Smart Wristband includes a Heart Rate Monitor function. To activate or view heart rate data, cycle through the display modes until the heart rate screen appears. Ensure the bracelet is worn snugly on your wrist for accurate readings.
Maintenance
1. Cleaning
To keep your wristband clean, wipe it regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the silicone band or display.
2. Water Resistance
The T5 Smart Wristband boasts an IP65 professional waterproof rating. This means it is resistant to splashes, sweat, and rain, making it suitable for activities like washing hands or face, and wearing in rainy conditions. However, it is not recommended for swimming or showering with hot water, as this could compromise the seal.

3. Wearing Comfort
The wristband is made from food-grade environmentally friendly silicone, designed for long-term wear. Its sweat-patterned design ensures comfort and breathability, even during extended use or physical activity.

Troubleshooting
- Device not turning on: Ensure the device is fully charged. Connect it to a USB power source and allow it to charge for at least 30 minutes before attempting to turn it on again.
- Inaccurate step count: Ensure the wristband is worn snugly on your wrist. Arm movements not associated with walking (e.g., typing) may sometimes be registered as steps.
- Display not responding: Try charging the device. If the issue persists, a soft reset might be needed (if applicable, consult manufacturer for specific reset procedures).
- Water damage: While IP65 rated, prolonged submersion or exposure to hot water can cause damage. If water ingress is suspected, discontinue use and allow the device to dry completely.
