6. Troubleshooting
If your device is not functioning correctly after installing new batteries, consider the following troubleshooting steps:
- Check Polarity: Ensure the batteries are inserted with the correct positive (+) and negative (-) orientation.

- Device Malfunction: If the device still does not work, the issue may be with the device itself, not the batteries. Refer to your device's manual or contact its manufacturer for further assistance.
