Installing a BCM unit on a wall

To wall-mount a BCM unit (main unit or expansion unit), you need the optional wall-mount kit

(NTAB3422).

To install a BCM unit on a wall

1 Mark the location of the plywood backboard on the wall using a pencil. Use a ruler and

bubble-level to check that the plywood backboard is level with respect to the wall.

2 Mount the plywood backboard securely to the wall.

3 Mark the location of the wall-mount bracket holes on the plywood backboard.

a Use the wall-mount bracket as a template.

b Use a bubble-level to check that the wall-mount bracket is level with respect to the

plywood backboard.

4 Install four #10 x 2.5 cm (#10 x 1 in.) round-head wood screws in the backboard (supplied).

a Do not tighten the screws heads against the backboard. Leave approximately 0.5 cm (0.25

in.) of the screw exposed from the backboard.

b Perform a trial installation of the wall-mount bracket on the plywood backboard. Ensure

the wood screw heads seat in the wall-mount bracket slots. If the wood screws are too

tight, loosen until the screw heads fit fully in the slots.

c Ensure that the wall-mount bracket is level with respect to the plywood backboard.

d Remove the wall-mount bracket.

The BCM200 main unit and

expansion unit are installed in

a similar manner.
