the screws for reassembly.

the front panel assembly. Save them for reassembly. (If the telephone contains an adapter plate that
holds a 3.5 inch speaker, remove the nuts that allow the entire adapter plate/speaker combination to
be removed.)

the four nylon shoulder washers from under the 4-inch speaker mounting holes. (These shoulder
washers can be dislodged with a small tool if they become embedded in the gasket material.)
