INTRODUCTION

Introduction

This manual is intended for Olympus-certified technicians. Use of this manual by other individuals is
prohibited.

Precautions

Before Repair

(1) Notify the site manager of the intent to repair the unit and obtain his/her approval before

commencing.

(2) During repair, there is a risk of injury from the various tools and parts in the vicinity, as well as

from fluid leakage on the floor. Inform the relevant people to restrict access to the repair area.

(3) To prevent potentially dangerous health risks, avoid working in a closed room, i.e., select a

well-ventilated location when using organic solvents.

(4) In general, it is advisable to record the function and operation settings before repair, to enable

restoration of the settings after service.

(5) If the original settings cannot be known due to mechanical problems present at the time the unit

was accepted for repair, apply the factory-set values, or the safest settings (such as the lowest
output levels). In such a case, inform the user that the settings have been changed.

(6) Guard against static electricity.

Use a conductive mat or wristband to discharge static electricity to prevent damaging the boards
or other electrical components if it is necessary to touch them.

During Repair

(1) To prevent potentially dangerous health risks, thoroughly rinse any bodily areas that have come

into contact with organic solvents as soon as possible.

(2) When using organic solvents, handle flames such as those in alcohol lamps with caution,

because these solvents may ignite if exposed to flame.

In addition, always replace the lids back onto organic solvent containers before leaving the
work-bench.

(3) Beware of electric shock.

Turn off the power and unplug the power cord before removing the cover of the unit.

(4) Beware of residual voltages.

The unit may contain residual charges in capacitor components. Take care to avoid electric
shock when opening the top cover.

(5) To avoid personal injury and damage to the unit, heavy units should always be assembled or

disassembled by at least two people.

(6) Repair with extreme caution to avoid injury.

Use extra caution around metal parts because the edges may be sharp.

(7) Reassemble parts according to their original configuration. This regards the following items

especially:
a) Insulators, such as insulating tubes and mylar sheets.
b) Cable rerouting, clamps, and cores.

c) Shield parts and cover screws with toothed washers.

Failure to attach parts in their original configurations, even if it does not impair product
function, poses the risk of noise radiation and reduced electrical safety.

(8) Use specified parts.

The parts and components of this product are designed to operate under certain anticipated
vibration, heat, chemical exposure, and voltage conditions. Always replace parts with those
specified in the parts list.

(9) Always tighten nuts/screws to the specified torque and only use components of the specified

dimensions.

(10) Do not reuse O-rings, E-rings, or packing. Always use new ones.
(11) When reusing components, remove sealing tape or sealing compound, and clean the

components before use.

(12) Check that no screws or nuts are loose.

After Repair

(1) After repair, inform the site manager of the nature of the problems, the cause, the

countermeasures taken, and the parts replaced.

(2) Always notify the site manager if, during repair, liquid disinfectants, cleaners, or alcohol were

used. Inform the site manager that before using the unit, it is necessary to verify the

concentration levels of disinfectants to ensure that they have not been diluted.

(3) Restore the original unit settings as they were recorded before repair. Request the presence of

site manager to verify the settings with you.

145/160 series videoscopes, EVIS EXERA II 165/180 series videoscopes, V series videoscopes, VISERA
series videoscopes, rigid light guides, fiberscopes, as well as EVIS EXERA II CV-180/165, and
endoscopic ultrasound systems.

Durability:
With adherance to the conditions listed below, this product has a usable life of 6 years from the
manufactured/shipped date.
Conditions: During this product’s usable life, the user must perform inspection before using, and

regular subsequent inspections as outlined in the attached materials and the operation
manual. Should the inspections reveal that repairs are required, the user must have
those repairs performed.

2 Features

(1) This is a light source unit for exclusive use with the EVIS EXERA II VIDEO SYSTEM CENTER

CV-180/165. However, this product is not to be used for surgery if used with the CV-165
(high-intensity function is not available).

(2) A mechanical detection unit is installed in the endoscope socket, enabling automatic switching to

the maximum amount of light appropriate for any endoscope connected. It is capable of
distinguishing between GI-type scope connectors, LG connectors for use with the SP high-intensity
function, and LG connectors for use with the non-SP, high-intensity function.

(3) When videoscopes or OES fiberscopes (including OES connectors used with BF and CHF type

endoscopes) are attached, the unit is capable of generating 1.3 times the output light intensity of
the CLV-U4 EVIS 100 mode and the OES mode (OAI, OLA). It produces 1.6 times more maximum
permissible illumination (white light) for the LG (non-OAI, OLA regions).

(4) When connected to a surgical fiberscope not compatible with the high-intensity RF connector, it

produces an output light intensity of the maximum permissible illumination (white light) for the LG
equivalent to the CLV-U4 EVIS 100 mode and the OES mode.

(5) When used with an endoscope and light guide compatible with the high-intensity RF connector, the

high-intensity mode is available, creating a brighter illumination. Compared to the illumination of the
CLV-U40 EVIS 100 mode or OES mode, approximately 2 times the maximum illumination (white
light) is produced. In high-intensity mode, it is also possible to select equal brightness or double
brightness of the CLV-U40 through the brightness mode switch.

(6) The optical filter used in NBI (narrowband imaging) observation has been loaded. NBI observations

are enabled when an NBI-compatible endoscope is connected to the unit.

(7) The optical filter used in PDD (photodynamic diagnosis) observation can be loaded (OE market).

One other optical filter for specialized observations may be loaded if required.
(8) The following modes may be selected:
a. Auto-ignition mode: the examination lamp automatically illuminates when the power is turned on.
b. Manual ignition mode: the examination lamp will illuminate when the lamp switch is pressed once

power has been turned on.
(9) The examination lamp can be manually turned off by continously pressing the LAMP switch for

approximately 1 second.
(10) Heat exhaust is through the rear (rear heat exhaust).
(11) The system automatically switches to the emergency lamp if the examination lamp does not come

on after pressing the lamp switch. As an emergency response, this will provide sufficient brightness

required for endoscope removal in situations when the examination lamp does not come on or if it

turns off. This will be indicated on the panel.
(12) Brightness can be adjusted using the 17 steps of automatic and manual brightness available.
(13) The air supply can be stopped completely as well as changed between high, medium or low supply.
(14) Disconnection of the emergency lamp will be automatically indicated on the panel.
(15) The transillumination switch enables the transmitted light illumination function (for GI endoscopes

only).
(16) Panel settings are retained, and the light source unit will display at the previous settings the next

time the unit is turned on. However filter switch settings are not backed up, and will revert to the

regular filter.
(17) The exterior and the operating panel may be disinfected with ethanol (70％ ethyl or isopropyl

alcohol) or with a mild detergent.
(18) This product has passed the OLYMPUS Eco-Product standard (Environmentally-friendly design

standard).

Precautions on disassembly and assembly CLV-180

Chapter 3: Precaution on
disassembly and reassembly

ISSUE 1

3-1

Precautions on disassembly and assembly CLV-180

1. Warning

(1) To prevent potentially dangerous health risks, select a well-ventilated location when using organic solvents.
(2) To prevent potentially dangerous health risks, rinse your body well under running water to wash away

organic solvents if any adhere to your body.

(3) When using organic solvents, handle flames such as those in alcohol lamps with caution since these

solvents may ignite if exposed to flame. In addition, be sure to put the lids on containers of organic solvents
before leaving the workbench.

2. Caution

(1) Attach parts in their original configurations during reassembly. Pay particularly close attention to the following

items:
a) Insulators, such as insulating tubes and mylar sheets
b) Cable rerouting, clamps, and cores
c) Shielded parts and covered screws with toothed washers
Failure to attach parts in their original configurations, even if it does not impair
product functions, poses the risk of noise radiation and reduced electrical safety.
(2) Exercise extreme caution to prevent possible injuries during reassembly. Be particularly careful to avoid

injuring yourself on the sharp edges of metal parts.
(3) Always use the specified components. The product is comprised of components designed to withstand

anticipated vibration, heat, and voltage. When replacing any component, make sure the replacement

component has the same characteristics as the original component, and always use the specified

components.
(4) Use the specified jigs and tools. The use of any unspecified jigs or tools may damage the AR-TZ2 or the

components under repair and prevent it from functioning properly or performing optimally.
(5) Be careful to avoid electrocution. Only remove the cover enclosing the OTV-SP1C after turning off the power

and unplugging the power cord, unless it is critically important not to do so.
(6) Be careful about residual voltage. Even if the unit is turned off before the cover is opened, keep in mind that

the capacitor may still hold a charge, so take care to avoid electrocution.
(7) Guard against static electricity. If it is necessary to touch the boards or other electrical components, to

prevent damaging them, use a conductive mat or wristband to discharge static electricity.
