Before handling internal telephone components, you must discharge
static electricity from your hands and tools by touching any grounded
metal surface or conductor.
1 Remove the handset and place the telephone upside down on top of a
level, solid work surface covered with soft material or paper to prevent
damage to movable keys and the telephone face.
2 Disconnect all cords from the telephone.
3 Remove the two screws from the footstand assembly and unsnap the
footstand assembly by pressing inward at the back of the footstand
where it meets the base and pulling upward.
4 If the telephone is equipped with an MPDA or MCA, unplug the data
cable from the base telephone jack. Remove the five screws securing
the base to the telephone. Remove the base and set it aside.

telephone is equipped with a display, go to step 6.

each end and pull upward to remove it. To replace it, go to step 9.
Removing the display
