84Using BluetoothBluetooth is used for wireless communication, e.g. between PCs or tablets andsmartphones or headsets. Bluetooth can be used at a distance of up to 10 me-ters. To exchange data between Bluetooth-enabled devices, the devices needto undergo a once-off pairing procedure.DiscoverabilityWhen first enabling a connection to a Bluetooth device, this function must beswitched on page 91.By default, the OpenScape CP600 can be found by other Bluetooth devicesonce you have opened the pairing menu.The OpenScape CP600 discoverability feature is disabled on exiting the pairingmenu in order to prevent misuse.PairingPairing is the process used by two Bluetooth-enabled devices to "see" one ano-ther and to "recognize" that they can exchange data. It is therefore used forchecking the access authorization of a Bluetooth device in a Bluetooth network.A connection key is generated for later identification.Pairing NFC-enabled devicesIf your Bluetooth device has an NFC reader (Near Field Communication), it canbe paired very easily with your OpenScape CP600 (often smartphones havethis, but not headsets).The NFC transmitter on the OpenScape CP600 is located in the top right areaof the display, to the left of the Forwarding key and below the "N" logo.To pair the Bluetooth device, hover over this logo and follow the instructions (seeinstructions for Bluetooth device).Please note that Bluetooth and NFC are not available on CP600E.A connection is established for devices that are already connected even ifthe "Discoverable" function is deactivated.Pairing is only performed the first time contact is established between aBluetooth device and your OpenScape CP600. If the Bluetooth device issuccessfully paired, no further access authorization checks are necessary.Instead, each subsequent check uses the previously created link key.
