Please ensure that the Nokia phone has at least firmware 5.5 on it. Early versions of the Nokia firmware were only designed to work with Nokia Bluetooth devices and so can cause problems.

Also ensure that the latest version of Nokia PC Suite for your phone is in use.

To find the firmware version currently installed on your phone, please see the phone’s documentation. For Nokia 6310’s the code is:

*#0000#

Although this may not be universal for all Nokia phones.
