To attach Otoscope/Throat Illuminator to power
source (Figure 1):
Align cutouts in the Otoscope/Throat Illuminator
base with lugs on power source. Push in slightly
and turn 90°. The Otoscope/Throat Illuminator is
now ready to use. To remove, reverse this
procedure. The Otoscope/Throat Illuminator fits all
3.5 v. Welch Allyn power sources.
To use Throat Illuminator (Figure 2):
1. Grasp the otoscope section with the left hand.
2. With the right hand, grasp the throat
illuminator’s collar at A (under the silver ring).
3. While holding the throat illuminator collar
stationary, twist the otoscope section
counterclockwise at A until the otoscope
section becomes loose.
4. Slide the right hand down to the power handle,
grasp it and turn it clockwise while keeping the
otoscope section stationary, until otoscope
section is removed. The throat illuminator is
now ready for use.
To replace otoscope section, reverse the steps.
Note: It is important to note that while the throat
illuminator section provides an excellent source of
general illumination, more then momentary direct
skin contact should be avoided due to possible
heat build up.
