9. User Tips

• **Bluetooth Stability**: For optimal performance, especially when connecting to a PC, it is highly recommended to use the provided Bluetooth adapter. If you choose not to use the adapter, ensure your computer's built-in Bluetooth function is stable and reliable to avoid connection issues.
• **Accessing Documentation**: If you require detailed documents such as module specifications, signal processing guides, or pin layouts, please contact customer service. They can provide the necessary files and SDK.
• **Battery Type**: The dry battery version does not include batteries. Ensure you have compatible batteries ready for use. The lithium battery version comes with its battery.

10. Maintenance

• Keep the TGAM module and electrodes clean and dry.
• Avoid exposing the device to extreme temperatures or humidity.
• Store the kit in a safe place when not in use to prevent damage to sensitive components.
• Regularly check electrode contacts for any signs of wear or corrosion.

11. Troubleshooting

11.1. Connection Issues

• **Device not pairing**: Ensure the TGAM module is powered on and within Bluetooth range. Verify your PC or Android device's Bluetooth is enabled and functioning correctly. If using a PC, try using the dedicated Bluetooth adapter.
• **Intermittent connection**: A weak or unstable Bluetooth signal can cause interruptions. Try moving closer to your device or using the recommended Bluetooth adapter for a more stable connection.

11.2. Poor Signal Quality

• **No or noisy EEG signal**: Ensure the electrodes are making good contact with the skin. Clean the skin area where electrodes are placed to remove oils or dirt. Check that all cable connections are secure.
• **Electrode placement**: Refer to the SDK documentation for optimal electrode placement for specific applications.
