Sensor switches in the cradle operate so that power is applied to a corded handle ONLY when it is lifted out
of its holder. The sensor switches for the two illuminators are wired so that only one instrument may be used
at a time and the other instrument must be in its proper hanger. The lamp intensity is controlled by turning
the rheostat clockwise to increase the light output. Turning the rheostat counterclockwise decreases the light
output.
