NOTE
y The screws mare with locking type threads so that some turning resistance will be felt when the
screws are seating.
Jj 16. Insert the transfer and CPU boards into the unit housing as follows:
, a) Hold the ribbon cable out of the way and insert the boards into the slots formed by the right and
i left covers until about one inch of the boards is exposed.
b) Insert the ribbon cable into the connector on the solder side of the CPU board. Hold the ribbon
| cable against the solder side of the CPU board and push the boards all the way in.
