Please check, whether the Bluetooth accessory supports one of the given protocols, which are supported by the Gigaset:

• headset profile (for Bluetooth headsets)
• handsfree profile (for Bluetooth headsets)
• serial port profile (for PC connection)
• OBEX (send/receive vCards)

When the Bluetooth accessory was installed already, please delete the registration from the handset:

• Bluetooth Menu
• Known Devices
• Select the accessory, e.g. a headset
• Options
• Delete Entry

If it is again not possible to register the accessory to the base station, please check, whether the accessory supports a reset-function, and execute it. Please pay attention that perhaps previous settings will be deleted in the accessory.

If you would like to use a headset already registered to another device (e.g., to a mobile phone) with your desktop phone, please deactivate this connection before you start the registration process.
