MS-RA55 Installation Instructions

Important Safety Information

WARNING

Failure to follow these warnings and cautions could result in personal injury, damage to the vessel, or poor product performance.

See the Important Safety and Product Information guide in the product box for product warnings and other important information.

This device must be installed according to these instructions. Disconnect the vessel's power supply before beginning to install

this product. Before applying power to this product, make sure it has been

correctly grounded, following the instructions in the guide.

CAUTION

Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.

NOTICE

When drilling or cutting, always check what is on the opposite side of the surface.

You must read all installation instructions before beginning the installation. If you experience difficulty during the installation, contact FUSION Product Support.

What's In the Box

• Mounting gasket

• Four 6-gauge, self-tapping screws

• Power and speaker wiring harness

• Two screw covers

• If you are installing the stereo in a location that may be exposed to water, the cable should have a drip loop to allow water to drip down off the cable and avoid damage to the stereo.

• If you need to mount the stereo outside a boat, it must be mounted in a location far above the waterline, where it is not submerged.

• If you need to mount the stereo outside a boat, it should be mounted in a location where it cannot be damaged by docks, pilings, or other pieces of equipment.

• To avoid interference with a magnetic compass, the stereo should be installed at least 15 cm (5.9 in.) away from a compass.

Mounting the Stereo

NOTICE

Be careful when cutting the hole to mount the stereo. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the stereo after it is mounted.

Be careful when installing the stereo in an aluminum boat or a boat with a conductive hull, if you require the electrical system to be isolated from the boat hull.

Do not apply grease or lubricant to the screws when fastening the stereo to the mounting surface. Grease or other lubricants can cause damage to the stereo housing.

Tools Needed

• Phillips screwdriver

• Electric drill

• Drill bit (size varies based on surface material and screws used)

• Rotary cutting tool or jigsaw

• Marine sealant (optional)

Mounting Considerations

• The stereo must be mounted on a flat surface.

• The stereo must be mounted in a location that allows open airflow around the rear of the stereo for heat ventilation.

• If you are installing the stereo in a location that may be exposed to water, it must be mounted within 45 degrees of the horizontal plane.

Before you can mount the stereo in a new location on the mounting surface, you must select a location in accordance with the mounting considerations.

Trim the template and make sure it fits at the mounting

location. Adhere the template to the mounting surface.

Using a drill bit appropriate for the mounting surface, drill a

hole inside the corner of the dashed line on the template to prepare the mounting surface for cutting.

Using a rotary-cutting tool, cut the mounting surface along

the inside of the dashed line on the template. Place the stereo in the cutout to test the fit.

If necessary, use a file and sandpaper to refine the size of

the cutout. After the stereo fits correctly in the cutout, ensure the

mounting holes on the stereo line up with the pilot holes on the template.

If the mounting holes on the stereo do not line up, mark the

new pilot-hole locations. Using an appropriately sized drill bit for the mounting surface

and screw type, drill the pilot holes. Remove the template from the mounting surface.

Make the necessary wiring connections (Connections,

page 2).

Place the mounting gasket on the back of the stereo À.

Place the stereo in the cutout.

Secure the stereo to the mounting surface using the included

screws Á. Snap the screw covers in place Â.

Connections

The stereo must be connected to power, to speakers, and to media input sources to function correctly. You should carefully plan the layout of the stereo, speakers, and your input sources before making any connections.

Notes

Connects the stereo to a typical AM/FM antenna using an RF coaxial connector.

If you are installing the stereo on a boat with a metal hull, you must use a ground-dependent antenna, and if you are installing the stereo on a boat with a non-metal hull, you must use a ground-independent antenna. See the installation instructions provided with your antenna for more information.

a 12 Vdc power source. This wire should be connected before connecting the yellow wire. All accessories connected to the stereo must share a common ground location.

Connecting to Power

When connecting the stereo to power, you should connect it through the ignition or another manual switch.

If it is necessary to extend the power and ground wires, use 14 AWG (2.08 mm2) wire. For extensions longer than 1 m (3 ft.), use 12 AWG (3.31 mm2) wire.

Route the power wire À to the ignition or another manual

switch Á, and route the black ground wire Â to the battery.

If necessary, route a wire Ã between the switch and the

battery . Route the wiring-harness plug to the stereo.

Do not connect the wiring harness to the stereo until after all of the bare wire connections have been made.

Connect the black wire to the negative (-) battery terminal.

Connect the power wire to the ignition or another manual

switch, and connect the switch to the positive (+) battery terminal if necessary.

Connect the wiring harness plug to the stereo.
