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.

SET-UP AND OPERATION After a 15-second warm-up period, the light output will stabilize at its normal intensity. The fiber optic bundle must be plugged in to stabilize light output.
CAUTION: Verify that the supply voltage matches the voltage range indicated on the rear of the Welch Allyn Light Source. To prevent temporary blinding, turn power on only after the fiber optic bundle is plugged in and the intensity control knob is set to the minimum position. The fiber optic bundle port is hot when fiber optic bundle is removed.

The lamp will take 15 seconds to complete its warm-up cycle. 4. Set light intensity to desired level. 5. Turn unit off when not in use. NOTE: Do not restart lamp immediately after turning off.
