3.3.3.1 Installing a Memory Board - Pre-midlife (Vector)
When ordering a memory upgrade from Nortek you will receive the following:
1. Long nylon screws
2. Mounting blocks
3. Short nylon screws
4. Nylon nuts
5. Threaded metal bolt
6. Nylon standoffs
7. Recorder board
A. Start with accessing the circuit board (Section 1.3.2).
B. To remove the compass board, start removing all screws and blocks with
the exception of the right mounting block on the main board, as shown in
the image. The point is to add two new mounting blocks (2) as support for
the recorder board.
C. Screw the metal bolt (5) through the mounting block (2) in the correct
hole (indicated in the image).
D. Screw the two blocks from (C) through the holes in the main board and
through another mounting block on the opposite side of the board (both new
blocks is to be placed on the same side of the main board). NOTE that the
block on the ‘compass’ side of the card sticks out over the edge of the
board, whereas the block on the ‘recorder’ side do not.
Please note the positions of the various holes in the mounting blocks: Make
sure that the twin holes are positioned ‘away’ from the center of the main
board. It is essential that they are positioned correctly.
E. Insert the two long nylon screws (1) through two of the holes in the
compass board, then through the nylon standoffs (6). Continue with
carefully inserting the screws through the two holes (at the opposite side of
the mounting blocks) on the main board. Attach two more standoffs, and
carefully position the recorder. Make sure the connector between the main
board and the recorder board ‘clicks’. Apply a little LocTite to all plastic
screws.
