First, turn on the watch by holding the button for 3 seconds. Enable Bluetooth and GPS on your phone. Open the H Band app, tap 'Click to connect the device', and select 'TFit500S'. If not found, swipe down to refresh. Do not pair directly from phone Bluetooth settings.

Why isn't my watch receiving notifications?

Ensure the watch is connected to the H Band app. In the app, turn on the 'Smart Reminder' and 'Call Reminder' functions. Also, go to watch settings > function settings to enable notification for specific apps. Make sure phone Bluetooth is on and the app has notification permissions.

Are the health measurements accurate?

The watch uses optical sensors and provides reference data, not medical-grade. For accurate readings, wear the band snugly on your wrist (behind the ulnar styloid), keep the sensor clean, and remain still during measurement. Factors like skin color, tattoos, or sweat can affect accuracy. Consult a doctor for medical decisions.

Can I swim or shower with the T-Fit 500 S?

It is water-resistant to IP68, meaning it handles rain, splashes, and sweat. However, do not swim or shower with it. Steam from hot showers can condense and damage the device. Dry it thoroughly if it gets wet.

How do I make calls with the watch?

After pairing via the H Band app, the call function may need manual activation. In the app, tap the 'Bluetooth call is not set' button to enable. Also, on the watch, swipe down to open control center and tap the Bluetooth call icon. Then search for 'TFit500S' in your phone's Bluetooth settings and pair. Then you can answer or make calls from the watch.

How long does the battery last?

The battery capacity is 370 mAh. Actual battery life depends on usage, but typically lasts 5-7 days with normal usage, including health monitoring and notifications. Charge with the included magnetic charging cable.

Can I listen to music from the watch?

Yes, if the call function is connected and media audio is enabled on the watch. In the control center, ensure the music/media icon is on. You can control phone music or play music stored on the watch (if any).

How does sleep monitoring work?

The watch automatically tracks your sleep from 8 PM to 10 AM the next day. It monitors sleep quality and provides a report. Short naps or movement may not be recorded accurately. Ensure the watch is worn snugly.

What is blood oxygen measurement and how to use it?

Blood oxygen (SpO2) measures oxygen saturation in your blood. Select the blood oxygen interface, then stay still. The motor vibrates when measurement is complete. For reference only, not for medical use.

What should I do if the H Band app fails to bind?

Update the app to the latest version. Ensure your phone meets the OS requirements (Android 8.0/iOS 13.0+). Restart Bluetooth on the phone, then reopen the app and search again. Also, make sure the watch is charged and turned on.
