5. Maintenance
- Cleaning: Wipe the scale surface with a damp cloth and mild detergent. Avoid abrasive cleaners or submerging the scale in water.
- Storage: Store the scale in a cool, dry place. Avoid extreme temperatures and direct sunlight.
- Battery Replacement: Replace the 3 AAA batteries when the low battery indicator appears on the display.
- Calibration: If the scale shows an error or inconsistent readings, recalibrate it by stepping on it briefly to turn it on, then stepping off and waiting for it to return to zero before taking a measurement.
6. Troubleshooting
- Scale not turning on: Check if the batteries are correctly installed and not depleted. Replace if necessary.
- Inconsistent readings: Ensure the scale is on a hard, flat surface. Avoid using it on carpet. Step on the scale barefoot and stand still. Recalibrate the scale if needed.
- App not connecting: Ensure Bluetooth is enabled on your mobile device and the scale is within range. Restart both the app and the scale.
- No body composition data in app: Ensure you are stepping on the scale barefoot, as the bioelectrical impedance analysis (BIA) requires direct skin contact with the sensors.
- Error messages (e.g., "Err", "Lo"): "Err" typically indicates an overload (weight exceeds maximum capacity). "Lo" indicates low battery.
