GDX Intercom Handset too loud - stuck :(

[Level01]

Hello everyone,

I am hoping someone can help or offer advice. I recently moved into a flat with a GDX intercom - the buzzer is SUPER loud. I'd rather have no sound at all, or reduce the volume to a minimum. From looking around here it seems people have DIY fixed similar problems.

Attached are some pictures from inside the intercom, which I think is a GDX 23121. If anyone has any ideas I'd be so grateful!

Have you tried turning it down via VR1 anti-clockwise? ( picture 3 )

Thanks for your help.

I had looked at that part and tried to manually turn the black casing, but it is fixed in place.

I can try to find something to fit in the white area maybe. To see if it turns something inside. None of the tools I had at the time would fit in there (it's kind of a weird shape, so I wasn't sure if it's meant to be turned or if it requires something specific). I will try to find something that fits and see.

It is the white inner part of the variable resistor that is meant to be rotated.
If you have anything like a jewellers screwdriver, or even the pointy end of a steak knife, it should be able to turn it.
...or you can get a specific 'potentiometer trimmer tool'

Perfect! Thank you and I really appreciate that. I will try that in the morning. If I can get it quiet enough that might be all it takes! If not it'll be an improvement anyway until I find a way to fully mute.

By the way, it is set to near maximum at the moment! Turning it the other way should be a big help

A flat, sharpened onto a match will turn that.

There is a mute button yep, but it only mutes it for a few hours. There doesn't seem to be a way to make it stay muted.

Sorry to requote but I just noticed a bit at the end of the picture you posted. "If... your handset is off hook, the handset will not ring when called". That sounds like it could be an easy fix!

Thanks so much everyone. I can't wait to try these things out this later / over the weekend and will report back. A quiet ring that I can disable fully at times would be amazing.

Did you not read the instructions ?
YOU CAN MUTE THE RINGER

I read and said above - the mute button only turns it off for a few hours.

 

[sparkymarka]

How long ? Have you tried it ?

That's what I've been using until present but it's not suitable for my needs.

Anyway, just a heads up to everyone to say thanks for the collective help. It's been good to learn some DIY info, for example learning what a potentiometer is.

The ringer is completely disabled when the phone is taken off, so I'll be using that method. I turned down the potentiometer too and will get someone soon to help me test if it's quieter - but either way, the buzzer will be fully off 99.9% of the time. Problem solved.
