1. Ensure the device is secured with a strong, unique PIN code.
2. Turn off the Bluetooth device when not in use.
3. Never accept files or connections from strangers.
4. Monitor the device's range indicator to stay within a safe radius.
5. Keep devices in view, away from public seating areas.
6. Cover the microphone to prevent eavesdroppers.
