- Storage: Store the device in a cool, dry place away from direct sunlight and moisture when not in use.
- Battery Care: For optimal battery life, avoid completely draining the battery frequently. Recharge when the indicator shows low battery.
8. Troubleshooting
If you encounter issues with your Mosiller Bug Zapper, consider the following:
- Device not activating: Ensure the power switch is in the correct position ("ON1" or "ON2") and the battery is charged. For manual mode, confirm the activation button is pressed.
- No 'zap' sound: This may indicate a low battery or that no insect has made contact with the active grid. Ensure the device is charged and the activation button is pressed (in manual mode).
- Ineffective in automatic mode: The UV light is most effective in dark environments. Ensure the area is sufficiently dark for optimal attraction.
