Switching from handsfree mode to the mobile phone
• If you have connected a compatible mobile phone to the Advanced
Car Kit using the data cable, take the phone out of the holder to
switch operation from handsfree mode over to the mobile phone.
• To change back to handsfree mode, replace the mobile phone in the
holder. The mobile phone is now used in handsfree mode via the
Advanced Car Kit.
• If you have connected a compatible mobile phone to the Advanced
Car Kit using Bluetooth technology, you can switch the active call
between the Advanced Car Kit and the mobile phone or vice versa.
Press and hold the button or use the corresponding function in your
mobile phone.
