Clarion M505 Installation Manual

This set is only for use with a 12v negative ground power supply. Before starting, make sure to disconnect the battery’s terminal. This will prevent short circuits from forming during installation.

The M505 should not be opened during installation. There are no user-friendly parts inside. If you find any issues, contact your local dealer or service center.

To clean the case, use a dry and soft cloth. Never use harsh chemicals or abrasive materials, such as benzine, alcohol, or rough cloth. For hard dirt, you can use warm or cold water to clean the surface.

Step before installation

  1. Prepare all articles necessary for installing the source unit before starting.
  2. Install the unit within 30° of the horizontal plane. (Figure 2)
  3. If you have to do any work on the vessel body, such as drilling holes, consult your vessel dealer beforehand.
  4. Use the enclosed screws for installation.

Source Unit Installation

  1. The mounting bracket should be placed inside the instrument panel. To secure the mounting bracket, use a screwdriver to twist the ends inward.
  2. After the source unit has been inserted into the mounting bracket, take care of the trim ring’s top and bottom to ensure that the hooks are locked.
  3. Some models have special mounting kits that need to be installed properly. Consult with your dealer about this issue. Also, fasten the front stopper to prevent it from coming loose.
  4. Make sure that the connections are made correctly to ensure that the unit operates properly. Also, avoid using unauthorized accessories since they can damage the unit. Before installing the source unit, make sure that all power cables are connected.
  5. Avoid installing the source unit near hot areas, such as the laser head. Doing so could lead to damage to the electrical components. Also, make sure that the wires are connected properly to avoid electric sparks.
