OPERATION:
Keyboard PCB
There are two styles of keyboard/keypad assemblies that have been produced. Original production used a conductive
trace and puck keyboard/keypad combination (shown at left in picture below). Current production uses a snap dome
switch and plunger keyboard/keypad combination (shown at right in picture below).
Do not mix assemblies. A conductive trace keyboard PCBA should always be used with a conductive puck
keypad. A snap dome keyboard PCBA should always be used with a plunger style keypad. Units should be repaired
with the style of keyboard/keypad they were originally built with.
