Operating the Welch Allyn Otoscope
1.
Turn on power. When the power
switch is on, the fan will power up and
light will be emitted from the end of
the Otoscope tip and through the light
vent.
2.
Ensure that the Light
Control Knob is turned all
the way to the right for
maximum light output.
ONCE THE LAMP IS TURNED ON IT WILL TAKE AT LEAST 15 SECONDS TO FULLY LIGHT UP
WHEN YOU TURN ON THE LAMP LEAVE IT ON FOR AT LEAST 60 SECONDS BEFORE TURNING OFF
3.
Perform a White Balance. A white balance (color reset) should be performed once a week, after the lamp is
replaced or whenever the image color appears distorted. To obtain good clinical images the natural colors must
be represented in the image.
To perform a White Balance:
1. Aim the Otoscope tip 1/2 to 1 inch away from a uniformly white sheet of paper.
2. While looking at the Otoscope light box, press the Color Reset button. A green light will
flash in the window to the right of the color reset button.
3. When it is done flashing, the white balance is complete. Release the Color Reset button.
