Lamp Replacement
NOTE: If lamp surface is touched or becomes smudged, wipe clean with a soft
cloth. This will assure longer lamp life and higher output. Lamps can be very
hot. Be sure lamp is cool before touching. For guaranteed performance, use
only genuine Welch Allyn lamps.
NOTE: When adequately tightened, instruments will be able to be swiveled in
both directions. After changing a lamp, to achieve the ability to swivel in both
directions, press firmly with thumb on the knurled portion of the instrument
adaptor while giving the instrument a sharp twist in the clockwise direction.
