4 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 Replace fuses as marked. See Fuse Replacement Section.
