Safety Considerations

• While this product is designed to be water­resistant, it should never be submerged
under water or subjected to high-pressure
water spray.

• Do not mount in areas of extreme heat.

• Ensure this product is securely installed so
that it does not come loose in the event
of a collision/sudden jolt or as a result or
repeated vibrations during normal operation.

• Check before drilling to make sure that you
will not be drilling into a fuel tank, gas/brake
line, wiring harness, or other vital system.

• Secure all wiring as needed, using cable
ties or wire clamps to protect them from
moving parts and sharp edges.

• Always follow proper safety procedures and
wear eye-protection at all times with a dust
mask and gloves when cutting.

The MMR-40 is equipped with a NMEA 2000®

Mounting & Installation
The diagram at right shows a typical
mounting procedure into a fiberglass panel.
A mounting template is included to aid
in measuring and marking the mounting
surface before cutting or drilling.

Make sure to carefully plan the routing of
the remote’s connection cables prior to
cutting or drilling any panels.

1. Press along the perforation to remove the
center section of the mounting template.
(Discard the center section.) The template
can be used to verify there is sufficient flat
surface area for mounting and as a guide
for cutting the opening. Tape the template
to the mounting location and mark the
surface for cutting the opening and drilling
pilot holes.

2. Use a jigsaw or rotary tool to cut an

opening in the mounting surface. If
necessary, use a file or sandpaper to
adjust the opening for proper fitment and
smooth the edges.

3. Place the MMR-40 into the opening and
check that the mounting holes remain
aligned with the pilot hole marks taken
from the template. If not, adjust and mark
new holes as necessary.

4. Remove the MMR-40 and drill four (4) pilot
holes in the mounting surface at the pilot
hole marks.

5. Peel the adhesive backing from the
mounting gasket and affix to the rear of
the bezel. Connect all wiring and place the
MMR-40 into the opening.

6. Secure the MMR-40 using the four (4)
mounting screws. Press the trim ring onto
the front of the MMR-40.
