Hi, can anyone please help with setting up Voice Dialling on a Nokia 2730?

The manual is pretty unhelpful and doesn't seem to explain the procedure.  As far as I can tell, one can somehow 'attach a tag' to a phone command/function for this but the only commands on offer appear to be Radio, Voice Mailbox, Profiles, etc ... everything but CALL or DIAL?

I'm sure I'm missing something fundamental here.

Tks,  R.
