Replacing the Keypad
1. Gain access to the instrument enclosure as previously

on the instrument. Using a knife blade or a thin flat
screwdriver, carefully lift a corner of the membrane (2).
Grasp the lifted corner and peel the membrane away from
the metal panel.

panel using IPA. Remove the adhesive backing from the
replacement membrane keypad. Pass the membrane cable
through the aperture in the panel, carefully locate the
membrane in position and smooth firmly in place.

place it back on the protected surface. Connect the
membrane cable to the Motherboard.

operation. Place the Front Panel Assembly back into position
