Always observe the following safety precautions to prevent injury or damage to the device:

- Battery: Use only the integrated rechargeable battery. Do not attempt to replace or modify the battery.
- Water Resistance: While the GL2 is water-resistant, it is not designed for submersion. Avoid prolonged exposure to water.
