LAMP REPLACEMENT
CAUTION: Lamp may be hot. Allow the lamp to cool before
replacing.
1. Turn unit off and unplug the power cord from both the wall outlet and the
Welch Allyn Light Source.
2. Remove the lamp door from the bottom of the Welch Allyn Light Source
by unscrewing the lamp access knob on the back of the lightbox.
3. Disconnect the lamp connector assembly and remove the lamp from the
holding spring assembly.
4. Replace with Welch Allyn replacement lamp #09500 only. Do not touch
the lamp itself, or the interior reflective surface of the lamp. Skin oils
on the lamp will cause premature lamp failure. Hold lamp by the outside
of the reflector or the connector only. Remove any grease or fingerprints
with a clean cotton swab moistened with alcohol. Do not leave any lint on
the lamp.
5. Reconnect the lamp to the lamp connector and place in the spring
mechanism. Be sure that the pin on the lamp is properly seated in
the slot on the lamp bracket.
6. Reattach the lamp door securely. The unit will not power up unless the
lamp door is seated properly.
