Signal words
The following signal words are used throughout this manual:
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not

Dangers, warnings and cautions
Follow the dangers, warnings and cautions given below when handling this light
source. This information is to be supplemented by the dangers, warnings and
cautions given in each chapter.
• As a TYPE BF applied part, this light source must never be
applied directly to the heart and must not be used in
procedures involving cardiac observation or surgery.
Leakage current from the TYPE BF applied part may be
dangerous and cause ventricular fibrillation or otherwise
seriously affect the cardiac function of the patient.
Accordingly, always adhere to the following points:
−Never apply the endoscope connected to this light source
to the heart or any area near the heart.
−Never allow an endo-therapy accessory or another
endoscope applied to or near the heart to come in contact
with an endoscope connected to this light source.

• Strictly observe the following precautions. Failure to do so
may place the patient and medical personnel in danger of an
electrical shock.
−When the light source is used to examine a patient, do not
allow metal parts of the endoscope or its accessories to
touch metal parts of other system components. Such
contact may cause unintended current flow to the patient.
−Keep liquids away from all electrical equipment. If fluids
are spilled on or into the unit, stop operation of the light
source at once and contact Olympus.
−Do not prepare, inspect or use this light source with wet
hands.
• Never install and operate the light source in locations where:
−The concentration of oxygen is high.
−Flammable anesthetics are present in the atmosphere.
Otherwise, explosion or fire may result because this light
source is not designed to be explosion-proof.
• Do not touch the light guide of the endoscope connector
immediately after removing it from the light source because it
is extremely hot. Operator or patient injury can result.
• Do not look directly into the distal end of the endoscope or
the output socket of this light source while the examination
lamp is ignited. The intense light may cause eye injury.
• To be prepared in case of a light source failure, always have
another light source available for immediate use.
• Xenon light sources produce significant heat due to the high
intensity light required for endoscopic procedures and can
cause a fire if brought into contact with flammable material.
To avoid this, make sure that the distal ends of the light guide
cable and endoscope do not touch drapes or other
flammable material. Also, make sure that light emitted from
the cable and scope is not directed toward a drape or other
flammable material. Turn OFF the light source whenever it is
not being used.
• The system should be establish with equipment complied
with relevant EMC standards for safety reason.
• Equipment which do not comply with EMC standard may
cause interference and its function or performance may be
affected.

• Portable or mobile phones may influence the medical
electrical equipment by their emitting energy.
• Do not use a pointed or hard object to press the switches on
the front panel. This may damage the switches.
• To avoid breaking electric contacts and causing a
malfunction:
−Do not touch the electric contacts of the light source
output socket.
−Do not subject any connector to excessive force.
As defined by the international safety standard
(IEC 60601-1:1988), medical electrical equipment is
classified into the following types: TYPE CF applied part (the
instrument can safely be applied to any part of the body,
including the heart), and TYPE B/BF applied part (the
instrument can safely be applied to any organ except the
heart). The part of the body a videoscope or electrosurgical
accessory can safely be applied to depends on the
classification of the equipment to which the instruments are
connected. Before beginning the procedure, check the
current leakage classification type of each instrument to be
used for the procedure. Classification types are clearly
specified on the instruments and in the instruments’
instruction manuals.

3.3 Connection of an endoscope
Before connecting the endoscope’s light guide connector to
the light source, make sure that it is perfectly dry. If the
endoscope’s light guide connector is wet (after disinfecting,
for example), wipe and dry the exterior as described in the
endoscope’s reprocessing manual. Otherwise, electrical
shock or equipment damage can result.
Insert the light guide connector into the output socket on the front panel of the
light source until it clicks into place (see Figure 3.5).

3.4 Connection of the OES video system
• Set the auto/manual brightness selector to “AUTO” to
prevent burns caused by close observation. So the
brightness is adjusted automatically. If using manual
brightness adjustment, set the brightness to the middle or
lower level and never observe close to mucous membranes
for a long time.
• When using rigidscope, set the auto/manual brightness
selector to “AUTO” to prevent burns caused by close
observation. So the brightness is adjusted automatically. If
using manual brightness adjustment, set the brightness to
the middle or lower level and never observe close to mucous
membranes for a long time.
