Help changing out door entry handset

[radus135]

trying (and failing) to change out an old videx handset for a bell 801

Can anyone help to tell me which wires go where?!

I cut the cable before taking it off to see where the old wires went in the videx

Stupidly presumed it would be a straight swap

R = 1 Speech Out (Mic)
T = 2 Speech In (Speaker)
Z = 5 Lock
I = 6 Buzz
O = 3 and 7 Common

Yes! Nice one cheers!
The mic still isn't working but it didn't with the old handset. Guessing this could this be an issue with the box on the front door down stairs? do you reckon this is a simple fix?

Thanks again

It could be just a broken wire. Do you have neighbours on the same system and does their mic work?

Thanks again for your reply.

Yes it's a block of 6 flats and all other neighbours are on the same system. I spoke with one this morning who said her mic doesn't work either. Reckon it's worth a try to open the box at the front door to see if there's anything obviously loose or broken? Anything else I should be looking for?

Broken wire or moisture ingress into the microphone bit of the speech box.

Nice one thanks - I had a look and all wiring seems ok within the box.

If the the mic is damaged due to water ingress I'm not going to mess around with it trying to find a new one.

(The neighbours generally aren't very good at reimbursing for improvements)

Thanks for your help
