WARNINGS AND PRECAUTIONS
WARNING: Possible explosion hazard. Do not use in the
presence of flammable anesthetics. To ensure patient
and operator safety, read and understand this manual
before using the Welch Allyn Light Source.
Do not remove cover. Electrical shock hazard due to high
internal voltage. There are no user serviceable parts
inside except for the lamp and fuse, which are accessible
through the bottom and back cover panels. Refer all
service to Welch Allyn.
Replace fuses as marked. See Fuse Replacement
Section, page 8.
The high intensity light at the front of the light source
and at the tip of the Fiber Optic Bundle may give rise
to high temperatures and bright light. To minimize the
risk of injury, avoid direct viewing or contact with
sensitive tissues.
Do not use for neonate transillumination. Erythema
may result.
To prevent temporary blinding, always plug the fiber optic
bundle into the Welch Allyn Light Source before turning
the power ON.
Total system risk current — including the patient applied
instrument — should not exceed 100 microamps. An
isolation transformer is required if total system risk
current exceeds 100 microamps when accessories
are interconnected.
Do not sterilize the Welch Allyn Light Source. Refer to
Cleaning section for cleaning instructions.
Do not switch the Welch Allyn Light Source ON and OFF
in rapid succession. Doing so will dramatically shorten
lamp life. Allow lamp to cool down 10 to 15 seconds
between uses.
