General Precautions
• For safety, this light source should only be coupled to a grounded 110-120V AC outlet
(hospital grade receptacle).
• The light source should not be operated in the presence of flammable or explosive gases
or chemicals or installed in areas where these materials are commonly utilized.
• To avoid overheating, the light source should be positioned on a hard, level surface and
the back of the light source should not be positioned closer than 6" to any wall.
• Keep all liquids away from electrical equipment to avoid the possibility of operator shock
and instrument damage.
• Occasionally inspect the power cord for signs of cuts, abrasions or dents.
• The light source should never be stored or operated in areas where it could get wet or
exposed to any environmental conditions such as extreme temperature, humidity, direct
sunlight, dust, etc.
• All service to the light source must be performed by Welch Allyn or an authorized
repair center.
• The light source and connected endoscope should not be used with electrosurgical
generators. The VideoSigmoidoscope system has not been designed for therapeutic
procedures.
• Light source use should adhere to the operating conditions found in this manual.
Otherwise, instrument damage may occur and/or operator/patient safety compromised.
