Bluetooth Security
The device supports Bluetooth Authentication and Encryption. Authentication can be requested by either the
remote device or the device. When Authentication is requested, the device uses its programmed PIN code to
generate a link key. The device stores this link key upon pairing, so you do not h ave to re-enter the PIN code when
moving in and out of range, switching profiles, or switching between devices (e.g., between the cradle and the
application).
Once Authentication is complete, either device may then negotiate t o enable Encryption.

Authentication

To force Authentication with a remote device (including the cradle), scan the Enable Auth entication bar code
below. To prevent the device from forcing Authentication, scan the Disable Authentication bar code below.
NOTE A remote device can still request Authentication.
