Remove the battery.

2.

Remove the top cover assembly following the procedures in

“Top Cover”

3.

Remove the display/keyboard assembly following the procedures in

Keyboard Assembly”

4.

Disconnect all remaining cable connections to the main PCB. These include
cables to the following:



power supply



printhead



battery connect PCB



acquisition module cable

5.

Remove the COMM board.

place. They are located around the outside edges of the main PCB. Set screws
aside for mounting new board.

7.

Remove the harness cable.

8.

Lift the main PCB from the unit.

Reassembly of CPU Board

1.

Insert the new CPU board in place and mount using the screws set aside during
