5. Maintenance
5.1 Cleaning
- After each use, especially in saltwater, wipe the main unit and wireless sensor immediately with a soft, dry cloth to remove any water or residue.
- Do not use abrasive cleaners or solvents.
5.2 Battery Care
- Recharge the main unit's lithium battery regularly, even if not in use, to maintain battery health.
- Replace the CR2032 battery in the wireless sensor as needed.
- Store the device in a cool, dry place when not in use.
6. Troubleshooting
6.1 Inaccurate Readings or Repeated Sonar Reception
- Issue: Sonar readings are inconsistent, show repeated signals, or are inaccurate.
- Solution: This often occurs when testing in smooth, hard places like water tanks, swimming pools, or buckets. The sonar signal bounces excessively, causing interference. Always test the device in outdoor deep water for accurate results.
6.2 Transducer Not Working
- Issue: The wireless sensor (transducer) does not appear to be transmitting or receiving data.
- Solution: Do not test the transducer in the air. The sensor is designed to activate and function correctly only when submerged in water. Ensure it is placed in an outside water area for testing and operation.
6.3 No Display or Power
- Issue: The main unit does not power on.
- Solution: Ensure the main unit is fully charged. If the issue persists, try charging with a different USB cable or adapter.
6.4 No Wireless Signal
- Issue: The main unit shows no wireless signal from the sensor.
- Solution: Check if the wireless sensor is properly submerged in water and its battery is functional. Ensure the main unit and sensor are within the 180m operational range.
