1.

To pull out the connection from console
PCB.

2.

If mull-function when you are using, please
find the PINs definition for keys terminal as
below.
To measure the PINs by multi-meter then
press the mull-function key and keep on, it
shall be have low resistance in the normal
condition(short condition), if got infinity
resistance, the membrane key is damaged.
For example: SPEED UP key mull-function, to
measure the Pin 4 and Pin 8.
