WARNING: THERE IS A RISK OF INJURY TO TISSUE FROM EXPOSIJRE TO THE INTENSE ILLUMINA-
TION. THE RISK OF INJURY IS REDUCED BY
USING THE MINIMUM LEVEL OF ILLUMINATION NEC-
ESSARY, BY MINIMIZING EXPOSURE TIME, AND BY AVOIDING CLOSE STATIONARY VIEWING.
WARNING: The high intensity light at the front of the light source and at the tip of a fiber optic bundle may
give rise to high temperatures. To minimize the risk of injury, avoid contact with tissues.
WARNING: As with any bright light, do not look into the beam. Permanent
eye injury may result.
To reduce the chance of direct visual exposure to the light, set the light intensity knob to the minimum
level and plug the fiber optic bundle into the light source before turning the power ON.
When the unit is on, never disconnect the fiber optic bundle from the light source or the accessory from the
end of the fiber bundle. High intensity light from the end of the fiber optic bundle and light source can
ignite flammable materials (i.e. drapes).
WARNING: TOTAL SYSTEM RISK CURRENT
- EXCLUDING THE PATIENT APPLIED INSTRIJMENT -
SHOULD NOT EXCEED 100 MICROAMPS. AN ISOLATION TRANSFORMER IS REQUIRED IF TOTAL
SYSTEM RISK CURRENT EXCEEDS 100 MICROAMPS WHEN ACCESSORIES ARE INTERCONNECTED.
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.
THE COVER OF THE LIGHT SOURCE SHOULD NEVER BE REMOVED. ELECTRICAL SHOCK HAZARD
DUE TO HIGH INTERNAL VOLTAGE. THERE ARE NO USER SERVICEABLE PARTS INSIDE THIS LIGHT
SOURCE EXCEPT FOR THE LAMP AND FUSE, WHICH ARE ACCESSIBLE THROUGH THE BOTTOM
AND SIDE DOOR PANELS. Refer all service to
Welch Allyn.

WARNING: Replace fuses as marked. See Fuse Replacement Section.
PROVIDE VENTILATION TO PREVENT OVERHEATING. Do not cover or drape the light source.
Do not use the turret as a light attenuator
or with the turret misaligned with the light port overheating will
result.
The ends of the fiber bundle get hot during use. Allow to cool before removing.
Do not operate light source without
lamp module in place.
CAUTION: IF THIS LIGHT SOLJRCE IS USED DURING INVASIVE SLJRGEKY, THE FAILURE OF A COM-
PONENT WITHIN THE SYSTEM, CAUSING LOSS OF ILLUMINATION, MAY DIRECTLY CAUSE RISK TO
THE PATIENT. THEREFORE, IT IS RECOMMENDED TO HAVE ALTERNATIVE MEANS OF
ILLUMINA-
TION AVAILABLE.
Since the light source uses a custom lamp, always have a spare lamp available for replacement.
Use only
Welch Allyn replacement lamp number 04980. USE CAUTION BECAUSE LAMP MAY BE HOT.
Allow the lamp to cool before replacing.
Equipment not protected against the ingress of water. Do not use or store liquids above or on the light
source.
Indications

LJnpack unit and visually inspect it for damage that may have occurred during shipment.
Plug power cord into light source power module and the remaining end into a hospital grade receptacle.
Select type of fiber optic bundles port (ACMI, Wolf, Olympus,
Storz) and rotate turret to align with light port.
Insure that the ends of the fiber optic bundle are clean before each
use. Any residue on the ends of the fiber
optic will absorb the high intensity light, and will overheat and damage the fiber optic bundle.
Insert fiber optic bundle into light port and connect the headlight luminare.Set light intensity to minimum
level. This prevents inadvertent shining into the patient’s or user’s eyes when turned on.
When the unit is on, NEVER disconnect the fiber optic bundle from the light source or the headlight from the
fiber optic bundle. High intensity light from the end of the fiber optic bundle and light source can ignite flam-
mable materials (i.e. drapes).
Turn the unit on.
Set light intensity to minimum level necessary for adequate visualization.
Turn unit off when not in use.
10. Allow to cool before removing fiber optic bundle.The ends of the fiber optic bundle get hot during use.
With the output of high intensity (Xenon) light sources, it is possible to convey a large amount of light energy and to
concentrate this energy in a very small area. This may result in thermal injury to the tissue.
The risk of injury is increased under the following
conditions:
1. Prolonged close contact or close stationary viewing of the mucosa or tissue.
2. Using a high intensity light source at high output levels.
3. Using multiple instruments to illuminate the same area.
The following recommendations will reduce the risk of thermal injury:
1. Use the minimum level of illumination necessary for adequate visualization.
2. When possible, avoid close stationary viewing.
3. Minimize exposure time.
Cleaning Instructions
NOTE: Welch Allyn Xenon 300 Light Source should not be sterilized or immersed.
1. Prior to cleaning, turn power off and disconnect the power cord from both the wall outlet and the Welch Allyn
Xenon 300 Light Source.
2. The external surfaces may be cleaned by wiping with a cloth dampened with mild soap and water or by using
the following cleaning/disinfecting solutions. DO NOT IMMERSE.
l 70% isopropyl alcohol
l 10% mild bleach solution
3. The power cord may be wiped clean using the same cleaning/disinfecting solutions listed above. Wipe dry with
a clean cloth. Care must be taken not to get the plug prongs wet. DO NOT IMMERSE.
4. Do not plug the unit into a wall outlet until it is thoroughly dry.
CAUTION: The ends of the fiber optic bundle must be clean before each use. High intensity light will be
absorbed by any residue (including cleaning and disinfecting solutions) on the surface of the fiber
optic. Absorbed light will overheat the residue causing damage to the fiber optic bundle.

2. Wait 5 minutes to allow the lamp to cool.
3. Unlock and open access door located on the side of the light source.
4. Grasp the two handles and pull the entire lamp module out of the light source.
To insert new lamp module:
1. Orient the new lamp module so that the window of the lamp is facing the front of the light source.
2. Carefully align the connection pins with the brass sockets on the lamp module and push firmly to
insure proper connection.
3. Close and lock the access door.
