5. Maintenance

Figure 5.1: Military-Grade Durability
The watch is built to military standards (MIL-STD-810H) for durability against impact, dust, corrosion, and extreme temperatures.
5.3 Battery Care
To maximize battery life, avoid fully discharging the battery frequently. Charge the watch when the battery level is low. Store the watch in a cool, dry place when not in use for extended periods.
6. Troubleshooting
6.1 Connectivity Issues
- Watch not pairing with phone: Ensure Bluetooth is enabled on both devices. Restart both the watch and the phone. Try unpairing and re-pairing through the GloryFitPro app.
- Notifications not appearing: Check app permissions in your phone settings to ensure GloryFitPro has access to notifications. Verify notification settings within the GloryFitPro app.
6.2 GPS Accuracy and Sync Time
- Slow GPS acquisition: For optimal GPS performance, ensure you are in an open outdoor area. If your phone is connected and has GPS enabled with full location permissions for the app, the watch can acquire a signal faster (within seconds). Without phone assistance, it may take 1.5 to 4 minutes to sync with satellites.
- Inaccurate tracking: Ensure the watch is worn securely on your wrist. Sync data regularly with the GloryFitPro app.
6.3 Sensor Readings
- Inconsistent health data: Ensure the watch is worn snugly on your wrist, not too loose or too tight. Clean the sensor area on the back of the watch. Sync the app regularly to update data.
6.4 General Performance
- Watch unresponsive: Try restarting the watch by long-pressing the power button. If unresponsive, allow the battery to fully drain and then recharge.
- Battery draining quickly: Reduce screen brightness, disable Always-On Display if not needed, limit background app refresh, and reduce the frequency of continuous health monitoring.
