Use the Bluetooth settings to enable/disable the use of an external reader and manage the encryption keys for locations.

• Encryption keys for location – the 2N^® Mobile Key - intercom communication is always encrypted. 2N^® Mobile Key cannot authenticate a user without knowing the encryption key. The primary encryption key is automatically generated upon the first start of the intercom and can be re-generated manually any time later. Together with Auth ID, the primary encryption key is transferred to the mobile device while pairing.
