I have a problem with my "mute" and "emergency" buttons in that when I depress them...they stay in and I have a dickens of a time getting them back out as they seem to stick. I assume this is from lack of use and being "mechanically challenged" I thought I had best ask those that have gone before. I don't want to damage them but would like to have the use of them...any suggestions...thanks...:watching::watching:

A lot of those switches are self cleaning so by pushing them on & off they will start working better. Other option is to sprat with some electrical contact cleaner & see if that helps.

Andy...thanks...not knowing what is inside I was dubious about spraying anything in there, would you suggest graphite or liquid spray.....:stumped:

Had the same issue with my 88. Get some electrical spray cleaner and wash the buttons down.

lots of threads on this in the forum. suggest opening up the housing(s) then spray the cleaner directly into the switch mechanics. on many of the switches the part you need to get the cleaner into is NOT near the button itself.

Not graphite as it's a conductor and can short out the switches.
