LIGHT BEAM CONTROLS



The intensity of the light beam is controlled 
by the small knob on the base of the unit 
just to the right of the joystick.

There is also a small button on the base 
near the light intensity control.  When this 
button is held down the light intensity goes 
to maximum.  This allows one to get 
maximum illumination for a short time 
without leaving the intensity at full strength 
for prolonged periods which can be 
uncomfortable to the patient and decrease 
bulb life.
