OK here goes. You select phonebook then press (say) the pqrs key. The
first press takes you to the start of the p's, the second to the q's.
You get a single beep acknowledgement each time. The third press you get
the r's. The fourth press, you stay at the r's and you get a 5 or 6 note
sound. Even though there are lots of entries beginning with s. If you
press pqrs again it moves to the s's. Anybody know wtf's happening?
