Remove the Switch Mat
The switch mat is held in place by the MMI PCB. Lift the switch mat clear of the casing.
RE-ASSEMBLY
Re-assembly is the reverse of disassembly. However:
(1) Examine the various seals before re-assembly and replace with new items if necessary.
(2) Slight outward deflection of the case walls will ease re-assembly of the MMI PCB behind the retaining
lugs.
(3) Care must be taken when reconnecting the flexi-circuits to ensure that they are correctly aligned before
pressing home the locking drawers on the connectors.
(4) Ensure that the metal screen is fitted to the PCB / frame assembly before the assembly is fitted to the
casing.
(5) To prevent damage to the frame seal, use a thin, flat piece of plastic (or other material) in a ‘shoehorn’
action between the bottom inside of the front case and the frame / PCB assembly as the assembly is
pushed home. Carefully remove the piece of plastic (or other material) after the frame / PCB assembly
has been fitted to the front case.
