INSTALLATION
Before You Begin
Before you begin, always disconnect the battery negative terminal.
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.
• Avoid installing the unit where it will be subject to high temperatures from direct sunlight,
hot air, or where it would be subject to excessive dust, or dirt.

1. Check the dashboard opening size by sliding the radio into it. If the opening is not large
enough, carefully cut or file as necessary until the radio slides into the opening. Check
that there will be sufficient space behind the dashboard for the radio chassis.
CAUTION: The rear of the radio must be supported with the strap to prevent damage to
the radio and supporting structures.
2. Place the radio in front of the dashboard opening so the wiring can be brought through the
opening.
3. Follow the wiring diagram carefully and make certain all connections are secure to ensure
proper operation.
4. After completing the wiring connections, turn the unit on to confirm operation (vessel
accessory 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 accessory switch off
and proceed with final mounting of the chassis.
5. Carefully slide the radio into the opening, making sure it is right-side-up.
6. Secure the radio to the dashboard using the screws provided.
7. Replace the covers on either side of the radio.
8. 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.
9. Test radio operation by referring to the operating instructions for the unit.
Removing the Unit
To remove the radio after installation, remove the covers and unscrew the installation screws,
and then pull the radio out.
Reconnect Battery
When wiring is complete, reconnect the battery negative terminal.
