Dangers and warnings
Follow the dangers and warnings given below when handling this instrument.
This information is to be supplemented by the dangers, warnings and cautions
given in each chapter.
S Failure to adhere to the following precautions may place the
patient and medical personnel in danger of electric shock.
-- When this equipment is used to examine a patient, do
not allow the metal parts of the endoscope or its
accessories to touch metal parts of other system
components. This instrument is electrically connected to
metal parts of other system components, and contact
may cause unintended current flow to the patient.
-- Do not prepare, inspect or use this equipment with wet
hands.
S Never install and/or operate the OTV-S7V in the following
locations. Otherwise, an explosion or a fire may occur.
-- The concentration of oxygen is high.
-- Oxidizing agents (such as nitrous oxide [N2O]) are
present in the atmosphere.
-- Flammable anesthetics are present in the atmosphere.
S Be sure to prepare another camera head to avoid that the
examination must be interrupted due to equipment failure or
malfunction.
S This product may interfere with other medical electronic
equipment used in combination with it. Before use, fully
confirm the compatibility of this instrument with all
equipment to be used with it.
S Do not use this product in any place where it may be subject
to strong electromagnetic radiation (for example, in the
vicinity of a microwave therapeutic device, MRI, wireless
set, short-wave therapeutic device, cellular/portable phone,
etc.). This may impair the performance of the product.

Important Information -- Please Read Before Use
Cardiac applications
S Use only the devices listed in the “System chart” 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.
S For cardiac applications, never support the endoscope with
a metal surgical arm that 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.
S 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 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 metal 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.
S The Olympus light guide cables and camera heads listed in
the “System chart (TYPE CF APPLIED PART)” which are
suitable for cardiac applications bear a
symbol.
S The Olympus surgical holder for telescope SH-1 has an
electrically isolated arm structure that isolates the
endoscope from the ground. This design makes the SH-1
suitable for cardiac applications.

Important Information -- Please Read Before Use
Precautions against frozen or lost endoscopic images
S If the endoscopic image unexpectedly disappears or a
frozen image cannot be restored during an examination,
immediately stop using the instrument and withdraw the
endoscope from the patient. Continued use of the
endoscope under these conditions may cause patient injury,
bleeding and/or perforation.
S Follow the precautions given below. Otherwise, the
endoscopic image may disappear unexpectedly, or it may
not be possible to restore a frozen image.
-- Never clean, disinfect, sterilize or store this instrument
together with sharp-tipped instruments (tweezers,
forceps, knives, etc.). These could scratch or tear holes
in the camera cable, which could allow water to penetrate
and damage electrical circuits inside the instrument.
-- Do not drop the camera head or allow it to strike other
objects. Strong impacts could damage the electrical
circuits inside the instrument.
-- Make sure that the video plug and its electrical contacts
are completely dry before connecting the plug to the
OTV-S7V. Wet contacts could cause the equipment to
malfunction.
-- Never excessively bend, pull, twist, coil, squeeze or
apply a crushing force to the camera cable. The camera
cable could become damaged.
-- Do not use excessive force when wiping the external
surfaces of the camera cable. Otherwise, the camera
cable could become damaged.
-- While the camera head is attached to the endoscope,
never attempt to lift the entire assembly by the camera
cable. Doing so could damage the cable.
-- Never use a clamp or forceps to attach the camera cable
to another object. Doing so could damage the cable.

` Selection of the scope imaging system
S When using camera heads with a black color code, select a rigid
endoscope without a fiber image guide. This will provide images with
high resolution appropriate for a rigid scope (see Figure 3.1).
S When using camera heads with an orange color code, either a rigid
endoscope or fiberscope can be used (see Figure 3.2). Scope images
with minimized moiré can be obtained by combining this camera head
with a fiberscope (see Figure 3.3).
S When using the camera head with rigid endoscopes only, select a
camera head with a black color code (see Figure 3.1).
S When using the camera head with fiberscopes and rigid endoscopes,
select a camera head with a orange color code (see Figure 3.2).

S Moiré is a striped pattern, either in color or B/W, that is
generated due to interference of the fiber mesh and the
picture element (see Figure 3.3).
S Use of camera heads with a black color code with
fiberscopes (including endoscopes equipped with a fiber
imaging bundle; e.g. Olympus NCS endoscopes) may result
in lower quality images that include moiré patterns and/or
color distortion. Use camera heads with an orange color
code with these fiberscopes.
S Camera heads with an orange color code can be used with
rigid endoscopes. However, when compared to camera
heads with a black color code, the image resolution is
reduced.
S If moire patterns appear or color fall-out occurs, rotate the
endoscope or adjust the focus to find the position with the
least moiré patterns or color fall-out.
S When using fiberscopes, turning the OTV-S7V ENHANCE
function OFF is recommended to reduce moiré patterns.
S Video output from the S-video terminal or the RGB output
terminal of the VISERA video system center will have less
moiré patterns than that from the BNC output terminal.
Therefore, when using a fiberscope, the S-video terminal or
the RGB output terminal is recommended for video output.

Inspection of the camera head
1. Inspect the camera head for cracks or other damage. Confirm that the
camera cable is not damaged.
2. Refer to Chapter 4, “Inspection” in the OTV-S7V’s instruction manual,
inspect the camera head.
3.3
Preparation of ancillary equipment
S To ensure safety, securely connect the power cord of the
OTV-S7V and the light source to a hospital grade receptacle
(wall mains outlet).
S When using a non-medical video monitor or other ancillary
equipment, always connect Olympus equipment via an
isolation transformer.
Setup the OTV-S7V, video monitor and other ancillary equipment as described
in the OTV-S7V VISERA video system center’s instruction manual and the
respective instruction manual for each piece of equipment.
3.4
Connecting the camera head to the VISERA
video system center OTV-S7V
S Never excessively bend, pull, twist, coil, squeeze or apply a
crushing force to the camera cable. The camera cable could
become damaged.
S Make sure that the video plug and its electrical contacts are
completely dry before connecting the plug to the OTV-S7V.
Wet contacts could cause the equipment to malfunction.
S Do not connect or disconnect the video plug while the
OTV-S7V is ON. Doing so may damage the electrical
circuits inside the camera head.
