• Keep your Bluetooth setting to “non-discoverable” (transmission-disabled) and only switch it to “discoverable” when you’re using it. Just leaving your mobile phone or PDA in the discoverable mode keeps it dangerously open for Bluetooth transmission—a Bluetooth user within up to a 30-foot range can receive your signal and potentially use it to access your device as you walk around town, drive, or even walk through your office.
  • Use a strong PIN code. Codes of five digits or longer are harder to crack.
  • Avoid storing sensitive data such as your social security number, credit card numbers, and passwords on any wireless device.
  • Stay up-to-date on Bluetooth developments and security issues, and regularly check with the manufacturer of your device for news on software updates or any specific security vulnerabilities.
