MA-1A
(1) SEMI-FLUSH MOUNTING TO WALL
1. Use a template to open a hole of H: 230 mm
X W; 140 mm (H; 9-1/16" x W: 5-1/2"), se
curing depth of 42 mm (1-5/8") or deeper.
2. Reinforce sides of the mounting frame by
wood frames, so that the mounting frame
be secured firmly to wall.
3. Attach the mounting frame to waU with 4
wood screws, so as to be fitted vertically to
wall.
4. Connect coaxial cable. Plug in connector
(male) after connecting cable by wire nuts.
5. Fit the MA-IA unit to the mounting frame
and attach top and bottom of the unit by 2
screws.
6. Hide the head of the upper screw by the
stuff provided.
(2) SURFACE MOUNTING TO WALL
1. Attach MAW-RA surface mounting box to
wall with 4 wood screws.
2. Attach the mounting frame to surface
mounting box by 4 screws.
3. Connect coaxial cable. Remove connector
(female) and connect to wires by wire nuts
and plug in to connector (male) on MA-1 A.
4. Fit the MA-1 A unit to the mounting frame
and attach top and bottom of the unit by 2
screws.
