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 Replace fuses as marked. See Fuse Replacement Section.

Directions for Use Chapter 1 Conventions 5
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.

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.
