To Adjust Light Beam Focus
This adjustment affects the sharpness of the light pattern at a specified distance. The light’s focus is factory preset for a distance of 27 in. (68.6 cm) from the front surface of the plastic shield to patient (target). However, the focus can be adjusted per user’s preference for any distance between 21 to 39 in. (53.3 to 99.0 cm).
1.Position plastic shield (1) of lighthead at any distance between 21 to 39 in. (53.3 to 99.0 cm) from a target (2) (wall, chair, or back section) and turn on light.
2.Using a screwdriver, pry focus cap (3) off back of lighthead.
3.Using a 1/8 in. Allen Wrench (provided), adjust focus screw (4) as necessary to achieve desired pattern. The suggested pattern is a 3 x 8 in. (8 x 20 cm) pattern, oval in shape, with feathered edges.
4.Install focus cap (3) on back of lighthead.
