clear of the chassis.
Fitting 1. Slide the SI board into the tray chassis by fitting the connectors b, c
and
d into the rear panel.
2. Press down firmly on the front of the SI board to engage the two
spring clips
j.
Important Make sure that the thermal pad is fitted under and the
plastic insulating washer is fitted on U406.
