OPERATING INSTRUCTIONS
The headlight is attached to the power source cord by a “Quick
Detach” connector/switch provided on the headband. This connector will accept only the 490 Series Headlights.
Correct headband size is obtained by use of headband adjustment screw.
For convenience, two on-off switches are furnished. The main
power switch is on the power source and is provided with a pilot
light. This may be left on when the headlight is not in use. A
secondary switch is incorporated on the “Quick Detach” connector at the back of the headband. To operate, simply push connector
all the way down for “on,” back up to the first click for “off.” This
all
switch operates headlight only. Pull
headband.
Top of power source has a flange to provide convenience for hang-
ing headlight when not in use.
The diameter of the light spot can be regulated from
at distance of 14” by means of a green knurled ring on the lamp
housing. This ring controls an iris diaphragm. The intensity of
light is uniform at 400 foot candles minimum over entire spot area
up to 3” diameter.
The halogen (regenerative cycle) lamp in this unit will provide
uniform intensity of illumination for the life of the lamp-no gradual
dimming. A sophisticated optical system eliminates filament image,
shadows or streaks. The natural tissue colors are preserved.

IMPORTANT
For best performance of halogen lamps, it is necessary to remove any grease or
fingerprints from the glass with a clean cloth moistened with alcohol.
Failure to follow cleaning procedure will result in permanent stains on the glass and
reduction of light output.
Fuse-Factory Replacement Necessary.
Ground Continuity Check-The resistance measured between the back plate of the
power source and the ground pin of the plug should be virtually zero.
