Chapter 1 Conventions Welch Allyn Xenon 300 Light Source
Warnings
A warning statement in this manual identifies a condition or practice which, if not corrected or discontinued immediately, could lead to patient injury, illness, or death.
WARNING It is the user’s responsibility to check the specifications of any device attached to this light source to verify that it can transmit the intense light output without generating high temperatures and heat build-up in the device that can cause serious burns.
WARNING High intensity light can cause burns to tissue even if the tip of the fiber optic cable or attached terminal device is cool. Burns are caused by the absorption of light by tissue and the subsequent conversion of that light energy into thermal energy. There is serious risk of igniting fires if the energized light cable fibers are placed on flammable materials, and full-thickness burns can be caused by prolonged exposure to concentrated light energy. Anesthetized patients are particularly susceptible to burn injuries via this mechanism. IT IS THE
USER’S RESPONSIBILITY TO DETERMINE AND MAINTAIN THE MINIMUM
SAFE DISTANCE BETWEEN THE END OF THE ENERGIZED FIBER-OPTIC
LIGHT PATH AND ANY LIVING TISSUE OR FLAMMABLE MATERIAL.
WARNING When used to power the Welch Allyn MFI Headlight system, we recommend a standard 16” working distance separating the headlight and the patient. Under no circumstances should the energized headlight be placed closer than 10” to any object.
WARNING There is a risk of injury to tissue from exposure to the intense illumination. The risk of injury is reduced by using the minimum level of illumination necessary, 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.
WARNING Total system risk current - excluding 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.
WARNING POSSIBLE EXPLOSION HAZARD. Equipment not suitable for use in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide.
WARNING
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

Cautions
A caution statement in this manual identifies a condition or practice which, if not corrected or discontinued immediately, could lead to equipment failure, equipment damage, or data loss.
Caution Consult users manual for important information.
Caution This system should only be used by qualified medical personnel.
Caution
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.
Caution 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).
Caution 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.
Caution
PROVIDE VENTILATION TO PREVENT OVERHEATING. Do not cover or drape the light source.
Caution
Do not use the turret as a light attenuator or with the turret misaligned with the light port, overheating will result.
Caution
The ends of the fiber bundle get hot during use. Allow to cool before removing.
Caution Do not operate light source without lamp module in place.
Caution If this light source is used during invasive surgery, the failure of a component within the system, causing loss of illumination, may directly cause risk to the patient. Therefore, it is recommended to have alternative means of illumination available.
Caution 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.
Caution
IPXØ - Equipment not protected against the ingress of water. Do not use or store liquids above or on the light source.

Chapter 2 Components Welch Allyn Xenon 300 Light Source
Set-Up and Operation
1.
Unpack unit and visually inspect it for damage that may have occurred during shipment.
2.
Plug power cord into light source power module and the remaining end into a hospital grade receptacle.
3.
Select type of fiber optic bundle port (ACMI, Wolf, Olympus, Storz) and rotate turret to align with light port.
4.
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 or damage the fiber optic bundle.
5.
Insert fiber optic bundle into light port and connect the headlight luminare. Set the light intensity to minimum level. This prevents inadvertent shining into the patient’s or user’s eyes when turned on.
Caution 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 flammable materials
(i.e. drapes).
6.
Turn the unit on.
7.
Set light intensity to minimum level necessary for adequate visualization.
8.
Turn unit off when not in use.
9.
Allow the light source to cool before removing fiber optic bundle. The ends of the fiber optic bundle get hot during use..
Caution 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.
Caution The risk of injury is increased under the following conditions:
• Prolonged close contact or close stationary viewing of the mucosa or tissue.
• Using a high intensity light source at high output levels.
• Using multiple instruments to illuminate the same area.
Caution The following recommendations will reduce the risk of thermal injury:
• Use the minimum level of illumination necessary for adequate visualization.
• When possible, avoid close stationary viewing.
• Minimize exposure time.

Maintenance
Cleaning Instructions
Note
Do not sterilize or immerse the Welch Allyn Xenon 300 Light Source.
1.
Turn power off and disconnect the power cord from both the wall outlet and the
Welch Allyn Xenon 300 Light Source.
2.
Wipe the external surfaces clean with a cloth dampened with mild soap and water or use one of the following cleaning/disinfecting solutions. DO NOT IMMERSE.
• 70% isopropyl alcohol
• 10% mild bleach solution
3.
Wipe the power cord clean using the same cleaning/disinfecting solutions listed above. Wipe dry with a clean cloth. Take care 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 Clean the ends of the fiber optic bundle before each use. Any residue
(including cleaning and disinfecting solutions) will absorb high intensity light on the surface of the fiber optic. Absorbed light will overheat the residue causing damage to the fiber optic bundle.
