Lower Intercom Volume

[IPLondon]

My flat has this old style intercom system with a very loud 'buzz' when someone presses the flat button outside the communal area.
Can I somehow lower the volume? I am pretty sure the buzz comes from the handset speaker, therefore would it be possible to add a volume controller to the yellow/green wire?

That's a bell system 801 handset the newer ones are tone generated via the speaker , there should be a jumper inside the handset base for high or low .

You are correct, it's 801 however I cant seem to find the jumper for High/Low?

Can you please show me in the attached pictures?
also what is the thin metal tap type switch to left of where the 801 is written?

Looks like you have an older version that does not have the jumper , it's normally to the left of the receiver switch ...

even their own brochure says that "The telephone has two levels for the ringing tone. A HI or LO position can be set within the telephone on installation or at future date." for all the three types of models..weird.

so what could I do about this nuisance buzz volume? would my plan (in original post) work?

OR.. I could just order a new 801PS model, but I would like to do some DIY and put a small toggle switch in myself if I could get some guidance

Not worth messing with , just replace with new version ....
