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 7.
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.
CAUTION: The Light Source should only be used by qualified medical
personnel.
Provide adequate ventilation to prevent overheating. Do not cover or drape
this light source. Provide a 3 inch (7.62 cm) distance between the Welch
Allyn Light Source and any solid objects.
Grounding reliability is achieved only when connected to hospital-use or
hospital-grade receptacles. Inspect electrical plug and cord routinely.
Do not use if damage is discovered.
Do not use or store liquids above or on the Welch Allyn Light Source.
If this light source is used during invasive surgery, the failure of a component
within the system, causing loss of illumination, may indirectly cause risk to
the patient. Therefore, it is recommended to have alternative means of
illumination available.
Since the light source uses a custom lamp, always have a spare lamp
available for replacement. Use caution because lamp may be hot.
Allow the lamp to cool before replacing. Use only Welch Allyn supplied
power cord.
