TANDEM card showing analogue audio sub-modules and PSU sub-module fitted
To fit a sub-module proceed as follows:
•
ensure that all static electricity precautions have been taken
•
fit two module retaining screws (3x10mm) from below the main PCB, and add a
nylon spacer (3x3mm) on top of the TANDEM PCB to each screw for each sub-
module location – hold screws firmly in place
•
offer up the chosen sub-module to its intended position on the TANDEM main
card
•
check that the orientation is correct and that retaining holes and header sockets
line up with the corresponding holes and header plugs on the main card
•
push the sub-module in place firmly taking care not to bend any pins
•
fit the retaining fibre washers, internal serrated washers and nuts to the two
retaining screws
Removal is the reverse of the above procedure.
