• Take the metal plate and place on the ceiling directly above the table's "rack spot" is best. If your light is in the way. No problem, simply move the mount towards the table end away from the light until the laser can clear the light.
• Center the mount plate as good as possible between the short sides and mark the three holes to drill out.
• Install the metal plate with plastic anchors and screws provided.
• Install three C cells into the unit and place the Spotmark II upon the ceiling and the magnetic mount will "snap" and hold it in place.
• Orient the Spotmark II for the sensor to "see" your table light.
• The sensor adjustment is the 1/4" hole on the bottom of the unit.
• Turn your pool light on and adjust the screw until the laser spot "just comes on".
• Spotmark II is adjusted correctly when it turns on and off with YOUR table light.
