Important Notes

•

Before final installation, test the wiring connections to make sure the unit is connected
properly and the system works.

•

Use only the parts included with the unit to ensure proper installation. The use of
unauthorized parts can cause malfunctions.

•

Consult with your nearest dealer if installation requires the drilling of holes or other
modifications to your vessel.

•

Install the unit where it does not interfere with driving and cannot injure passengers if
there is a sudden or emergency stop.

•

If the installation angle exceeds 30º from horizontal, the unit might not give optimum
performance.

•

This unit is not waterproof and is intended for interior mounting applications only.
Exterior mounting of the unit requires use of an ASA approved marine housing.

•

Avoid installing the unit where it will be subject to high temperatures from direct sunlight,
hot air, or from a heater, or where it would be subject to excessive dust, dirt or vibration.

DIN Front Mount

Slide the mounting sleeve off of the chas-
sis if it has not already been removed. If it
is locked into position, use the removal
keys (supplied) to disengage it. The
removal keys are depicted in “Removing
the Unit” on page 3.

Check the dashboard opening size by
sliding the mounting sleeve into it. If the
opening is not large enough, carefully cut
or file as necessary until the sleeve easily
slides into the opening. Do not force the
sleeve into the opening or cause it to bend
or bow. Check that there will be sufficient space behind the dashboard for the radio
chassis.

Locate the series of bend tabs along the top, bottom and sides of the mounting sleeve.
With the sleeve fully inserted into the dashboard opening, bend as many of the tabs
outward as necessary to firmly secure the sleeve to the dashboard.

Place the radio in front of the dashboard opening so the wiring can be brought through the
mounting sleeve.

Follow the wiring diagram carefully and make certain all connections are secure and
insulated with crimp connectors or electrical tape to ensure proper operation.

After completing the wiring connections, turn the unit on to confirm operation (vessel
ignition switch must be on). If the unit does not operate, recheck all wiring until the
problem is corrected. Once proper operation is achieved, turn the ignition switch off and
proceed with final mounting of the chassis.

Carefully slide the radio into the mounting sleeve making sure it is right-side-up until it is
fully seated and the spring clips lock it into place.

Attach one end of the
perforated support
strap (supplied) to the
screw stud on the rear
of the chassis using the
hex nut and spring
washer provided.
Fasten the other end of
the perforated strap to a
secure part of the
dashboard either above
or below the radio using
the screw and plain
washer provided. Bend
the strap, as necessary, to position it.

CAUTION: The rear of the radio must be supported with the strap to prevent damage to
the dashboard from the weight of the radio or improper operation due to vibration.

Test radio operation by referring to the operating instructions for the unit.

Removing the Unit

To remove the radio after installation:
1.

Insert fingers into the groove in the front of
frame and pull out to remove the frame.
(When re-attaching the frame, point the
side with a groove downwards and re-
attach.)

Insert the removal keys straight back until
they click, and then pull the radio out. If
removal keys are inserted at an angle,
they will not lock properly to release the
unit.

Trim Plate Installation

Push the trim plate against the chassis until it is
fitted.

Reconnect Battery

When wiring is complete, reconnect the battery
negative terminal.
