3210 no ringtone - no top pads


hi all.
i have 3210 with no ringtone, after inspection it has no ringer (top right) and the two top pads are gone completely.
i have searched the wiring diagrams to see if they can be jumped to somewhere. but my manual is rubbish and is not there. so if anyone can help i would appreciate it.
many thanx

many thanx willy....
but how do you know this.
I AM GOING THROUGH THE DOCUMENT YOU SENT ME AS WE SPEAK,
firstly do you know where i can learn howto read these diagrams correctly.
There are four contacts to ther ringer(buzzer) however the diagrams are not clear to me which one is which.
i know you are correct in you diagnoses, its me thats wrong.
i find it very difficult to actually picture where these four contacts are, therefore find it hard to know which line to follow....as far as i can see the diagram only shows two of the contacts.
please feel free to ignore these questions as they are very involve and i know your busy
many thanx

ok, you need to use multi tester ,, and you can easy to fine which 2 pin used, and which pin for "holder" !

or you look at that DOC you have it now, see page 6, and you can see which make a "+" this mark in B400, then go to page 10 , then you can also see that buzzer has a mark "+" , then you can make sure that is "+" this pin !
