Dual pair Motorola HT820 with phone and PC

Hi,

I have the Mototola HT820 bluetooth stereo headset and it works
perfectly on both my computer and phone(N95) when individually paired
to one or the other.

I can't seem to manage to simultaneously pair the both of them so I
have to reconnect it each time I want to use it on either device.

The manual says that you can simultaneously connect two devices via
bluetooth, but i cant figure it out . help!!

cheers
