INSTALLATION MANUAL

Installation
Note:
� Before making a final installation of the unit, temporarily connect the wiring to confirm that the connections are correct and the system works properly. 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 of the vehicle. Install the unit where it does not get in the driver�s way and cannot injure the passenger if there is a sudden stop, like an emergency stop. The semiconductor laser will be damaged if it overheats, so don�t install the unit anywhere hot � for instance, near a heater outlet. If installation angle exceeds 60° from horizontal, the unit might not give its optimum performance. (Fig. 1) When installing, to ensure proper heat dispersal when using this unit, make sure you leave ample space behind the rear panel and wrap any loose cables so they are not blocking the vents.
