Chapter 5 Operation
The operator of this light source must be a physician or medical personnel under
the supervision of a physician and must have received sufficient training in
clinical endoscopic technique. This manual, therefore, does not explain or
discuss clinical endoscopic procedures. It only describes basic operation and
precautions related to the operation of this light source.
• Wear personal protective equipment to guard against
dangerous chemicals and potentially infectious material.
During operation, wear appropriate personal protective
equipment, such as eye wear, face mask, moisture-resistant
clothing and chemical-resistant gloves that fit properly and
are long enough so that your skin is not exposed.
Chapter 5 Operation
• If the examination lamp does not ignite or go off with blinking
the brightness level indicators, immediately stop using the
light source and withdraw the endoscope from the patient
slowly as described in the endoscope’s instruction manual.
And then, contact Olympus.
• Anytime you suspect an abnormality in a light source
function, stop the examination immediately. Take action
according to the procedures described below. Using a
defective light source may cause injury.
− If the image on the monitor becomes completely white or
black when the automatic brightness adjustment is
selected, the automatic brightness adjustment may be
malfunctioning. In this case, set the auto/manual
brightness selector to “MAN.” and adjust the brightness
manually. Withdraw the endoscope from the patient
slowly as described in the endoscope’s instruction
manual.
− If the examination lamp fails and the emergency lamp
lights, withdraw the endoscope from the patient slowly as
described in the endoscope’s instruction manual.
− The emergency lamp provides only the absolute minimum
of light needed to keep operating in an emergency, so do
not use the emergency lamp for operation unless
absolutely necessary.
EVIS EXERA XENON LIGHT SOURCE CLV-160
31
Page 36
Chapter 5 Operation
− If any other abnormality occurs or is suspected, stop
using the equipment and immediately withdraw the
endoscope from the patient slowly as described in the
endoscope’s instruction manual. Then refer to the
instructions in Chapter 8, “Troubleshooting”. If the
problems cannot be resolved by the remedial action as
described in Chapter 8, do not use this light source on a
patient again and immediately contact Olympus.
• Whenever possible, do not leave the endoscope illuminated
before and/or after an examination. Continued illumination
will cause the distal end of the endoscope to become hot and
could cause operator and/or patient burns.
• Turn the video system center ON to operate the light
source’s auto-brightness function. When the video system
center is OFF, it cannot operate the light source’s
auto-brightness function, and the light intensity is set to the
maximum level. In this case, the distal end of the endoscope
can become hot and could cause operator and/or patient
burns.
• Do not use the light source in a location exposed to strong
electromagnetic radiation (e.g., near microwave medical
treatment equipment, short wave medical treatment
equipment. MRI equipment or radio). Brightness fluctuation
can occur.
• It is recommended to use only Olympus high frequency
electrosurgical equipment with this unit. Non-Olympus
equipment can cause interference on the monitor display or a
loss of the endoscopic image.
Set the brightness of the light source to the minimum
necessary to perform the procedure safely. If the endoscope
is used for a prolonged period at or near maximum light
intensity, vapor like smoke may be observed in the
endoscopic image. This is caused by the evaporation of
organic material (remaining blood, moisture of stool and so
on) due to heat generated by the light guide near the light
guide lens. If this vapor continues to interfere with the
examination, remove the endoscope, wipe the distal end of
the endoscope with a lint-free cloth moistened with 70% ethyl
or isopropyl alcohol, reinsert the endoscope and continue the
examination.

When the lamp life indicator “500 h” is lit, replace the examination (xenon) lamp
as instructed below. Although the lamp brightness from the distal end of the
endoscope depends on the part being observed, the lamp should be replaced as
soon as the lamp appears darker than normal, even if the lamp life indicator
“500 h” is not yet lit.
• The lamp life indicator displays the total working hours of the
examination (xenon) lamp (e.g. “500 h” means about
500 hours).
• The examination lamp can be replaced by the user as
described in Section 6.2.
• The emergency lamp cannot be replaced by the user. If the
emergency lamp has burned out or is out of order, contact
Olympus.
6.2 Replacement of the examination (xenon) lamp
• Do not touch anything inside the lamp chamber. The lamp
chamber is extremely hot immediately after the lamp is
