6. Maintenance
6.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing or screen.
6.2 Battery Care
To prolong battery life, avoid fully discharging the device frequently. Recharge the battery when the low battery indicator appears. If storing the device for an extended period, charge it to approximately 50% every few months.
6.3 Storage
Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Keep it away from strong magnetic fields.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or device malfunction. | Charge the device for at least 30 minutes. If it still doesn't power on, contact support. |
| Inaccurate readings. | Interference from other electronic devices or incorrect unit settings. | Move away from potential sources of electromagnetic interference. Verify the correct measurement unit is selected in settings. |
| Alarm not sounding/vibrating. | Alarm thresholds not set or alarm mode disabled. | Check alarm settings and ensure desired alarm modes (sound, vibrate, light) are enabled. |
| Screen is blank or frozen. | Software glitch. | Press and hold the power button for 10-15 seconds to force a restart. If the issue persists, contact support. |
