distal end is required for endoscopic observation and treatment, it may also cause alteration of living tissues such as protein denaturation of liver tissue and perforation of the intestines by inappropriate use. Observe the following warnings on the illumination.
Always set the minimum required brightness. The
brightness of the image on a video monitor may differ from the actual brightness at the distal end of an endoscope. Especially in combination with endoscopes using an electrical shutter function, pay attention to the brightness level setting of the light source. When this instrument is used with a light source compatible with automatic brightness control function, be sure to use this function. The automatic brightness control function can keep the illumination light properly. Refer to the instruction manual of the light source for details.
Do not continue observation in the proximity to tissue or
keep the distal end of the endoscope in contact with living tissue for a long time. It may cause patient burns.
When discontinuing the use of the endoscope, be sure to
turn the light source OFF so that the endoscope does not irradiate unnecessary light.

Cardiac applications

Important Information — Please Read Before Use
• Use only the devices listed in the “System chart” in the
Appendix for endoscopic observation or treatment of the heart or areas near the heart. Other combinations of equipment may cause ventricular fibrillation or seriously affect the cardiac function of the patient.
• For cardiac applications, never support the endoscope with a
metal surgical arm which is not electrically isolated from the ground. If not isolated, the endoscope will be connected to the ground through the surgical arm and bed, and will conduct unexpected leakage current which may seriously affect the cardiac function of the patient.
• The use of medical devices not specifically designed for
cardiac applications may cause ventricular fibrillation or seriously affect the cardiac function of the patient. As specified by the international standard IEC 60601-1, any applied part used for observation or treatment of the heart or areas near the heart must meet “TYPE CF applied part” requirements for low electrical leakage current. When using endoscopes for endoscopic cardiac applications, the applied part requirements include all devices directly connected to the endoscope, such as the light guide cable, camera head and telescope holder. Each of these devices must individually meet the “TYPE CF applied part” requirements for leakage current limits if they are to be used for cardiac applications.
The OLYMPUS light guide cables and camera heads listed in the “System chart” in the Appendix (TYPE CF applied part)
which are suitable for cardiac applications bear a mark.

Chapter 4 Operation
This chapter explains the work flow of endoscopic observation using the video system center. For information on how to use the functions that are not explained in this chapter, refer to the reference pages.
The operator of the video system center must be a physician or medical personnel under the supervision of a physician and must have received sufficient training in clinical endoscopic techniques. This manual, therefore, does not explain or discuss clinical endoscopic procedures. It only describes basic operation and precautions related to the operation of the video system center.
• Be sure to wear 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. Otherwise, dangerous chemicals and/or potentially infectious material such as blood and/or mucus of the patient may cause an infection.

Chapter 4 Operation

• Should any irregularity is observed, do not use the video system center. Damage or irregularity may compromise patient or user safety and may result in more severe equipment damage.
• Anytime you observe an abnormality in a video system center function, stop the examination immediately and take action according to the following procedures. Using a defective video system center may cause patient and/or operator injury.
If the endoscopic image disappears or if the image
freezes and cannot be restored, press the “RESET” button or temporarily turn the video system center OFF and wait for about 10 seconds. Then turn it back ON again.

Chapter 4 Operation
If any other abnormality occurs or is suspected,
immediately stop using the equipment, turn OFF all equipment, and gently withdraw the endoscope from the patient as described in the endoscope's instruction manual. Then refer to the instructions in Chapter 10, “Troubleshooting”. If the problems cannot be resolved by the remedial action described in Chapter 10, do not use the equipment and contact Olympus.
• Combination with other equipment
Do not use the video system center in locations exposed
to direct strong electromagnetic radiations (for example, microwave treatment device, short wave treatment device, MRI or radio equipment). Electromagnetic radiation can interfere with the monitor display.
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.
Before using high-frequency electrosurgical equipment,
be sure to install and connect the equipment according to it’s instruction manual and make sure that the noise does not affect the observation and surgical procedures. If high-frequency electrosurgical equipment is used without such confirmation, patient injury may result.
• To activate the auto brightness control function of the light source, the video system center should be turned ON. If it is not turned ON, the auto brightness control function is not activated and the light intensity is set to maximum. In this case, the endoscope distal end would become hot and could cause burns to the operator and physician (if a light source model other than CLV-180 is used).
• When using spray-type medical agents such as lubricant, anesthetic, or alcohol, use them away from the video system center so that the medical agents do not contact the video system center. Medical agents might enter the video system center through the ventilation grills and may cause equipment damage.
42
• Do not use a humidifier near the video system center as dew condensation possibly might occur and it may cause equipment failure.

4.5 White balance adjustment
This adjustment procedure is used to display the correct image color on the monitor. There are two white balance adjustments for the normal observation and the NBI observation. Be sure to always adjust the white balance in the following cases:
• Before observation.
• After exchange of the light source.
• When any abnormality can be seen on the color of the image even if white balance adjustment has been completed.
• When adjusting the white balance of the endoscope to be used in the sterilized zone, do not use the white cap (MH-
155) as described in this part, but use a white object such as a piece of gauze without bringing it in contact with the endoscope. Contact of the endoscope with a non-sterilized object may result in cross-contamination.
• Make sure that the endoscope and white cap (MH-155) are clean before adjusting the white balance. Otherwise, cross­contamination may result.
• Always control the color tone and/or enhancement of the image appropriately before observation. Setting an inappropriate color tone or enhancement condition may result in overlooking or wrong diagnosis.

• Always use the minimum level of illumination necessary for adequate viewing. Whenever possible, avoid close, stationary viewing of mucous membranes for a long time. Intense endoscopic illumination may cause mucosal burns.
• Do not bring the metal plug of the light guide and the distal end of the endoscope immediately after use in contact with the body and flammable objects because the parts will be extremely hot.
• Be sure to set the brightness control mode of the light source to manual mode or turn the examination lamp OFF before disconnecting the camera head from the endoscope or disconnecting the videoscope from the video system center. Disconnecting them can increase the light intensity to the maximum and may cause burns or eye injury.
