The ELECTROSURGICAL UNIT UES-40 (UES-40) is designed for use in medical facilities
under doctor supervision in combination with designated reusable high-frequency instruments, endoscopes, and light sources in surgical procedures and treatment using endoscopes (fiber scopes, videoscopes, and rigid scopes) for the cutting and coagulation of living
tissue.
(1) Expanding the functions available with the UES-30
The UES-40 also offers an output system for use in physiological saline (TURis). TURis
frees surgeons from the need for a patient plate, and offers improved safety over conventional TUR is.
TURis (TUR in saline): A technique for cutting and ablation in physiological saline
TUR: Transurethral resection of the prostate
(2) Supports the use of multiple electrodes
(Separate settings can be used for each system: bipolar, monopolar, and saline.)
(3) The UES-40 features exclusive specifications and is compatible with EndoALPHA.
(4) For easier use, the front panel is designed at a 20° vertical orientation.
(5) The design of the UES-40 is coordinated with the VISERA Video System.

3. Operating Requirements
(1) The operating conditions must be as follows.
Ambient temperature:10°C to 40°C
Relative humidity:30% to 85%
Atmospheric pressure: 700 hPa to 1060 hPa
Never use the UES-40 where flammable vapors occur.
(2) The power requirements are as follows.
Rated input voltage120 V220 V
Rated input current12A6A
Frequency50/60 Hz
Permissible voltage fluctuation±10%
(3) Do not use in combination with products not designated by Olympus.
(4) Before using the UES-40 for the treatment of patient s weari ng pacemakers, consult the
pacemaker manufacturer.
(5) Do not attach the patient plate for use near metallic implants.
(6) Do not wind UES-40 cords into loops or allow them to touch the patient or metall ic p art s
of the surgical table.
(7) Do not bundle UES-40 cords with cords of other medical equipment during use.
(8) Keep the UES-40 and its cords adequately separated from other medical equipment
and cords.
(9) If non-CF products are used in combination with the UES-40, do not use directly on the
heart.
(10) To ensure electrical safety, use of the following electronic medical equipment in combi-
nation with the UES-40 is prohibited:
a)Equipment not yet proven safe when used with the UES-40
b)Equipment not yet proven safe due to certain aspects of operation (such as the
leakage current)
(11) If the UES-40 is used in combination with endoscopic instruments for which the rated
voltage is listed in each instrument user manual, compare the open outpu t-volt age char-
acteristics of the instruments with those of the UES-40 and adjust the output within the
USE-40’s rated voltage values. Refer to Fig. 1-1 to 1-4 for the open voltage characteris-
tics. If the user’s manuals for these instruments do not list the rated voltage, set the out-
put low initially and then gradually increase the output level.

Parts That Might Have Caused the Problem
Monitor board (J7) – Relay board (J2)

Used where the high-frequency current is prone to leakage. (Touching
metal parts of patient’s bed or objects
such as external devices that have
fallen to the ground; used simultaneously with high-frequency grounded
(1) Keep all components safe, since you will need to reattach them at their original positions and reroute
the cables as originally routed.
(2) Exercise extreme caution to prevent possible injuries during disassembly.
Be especially careful to avoid injuring yourself on the sharp edges of metal parts.
(3) Remove the cable housing carefully. Never detach cables by pulling on them.
(4) To ensure electrical safety in accordance with the governing electrical standards, attach the following
in their original configurations when reassembling:
a)Insulators, such as insulating tubes and mylar sheets
b)Cables tied with binder to keep them from touching heat-generating and high-voltage compo-
nents
c)Cover screws with toothed washers to reduce noise radiation
(5) Always use specified components.
The product is comprised of components designed to withstand anticipated vibration, heat, and volt-
age. When replacing any component, make sure that the replacement component has the same
characteristics as the original component.
(6) Be sure to use the specified tightening torque and components of specified dimensions.
(7) Clean the components.
When reusing components, first remove any sealing tape and sealing compound, then clean them.
Note that you must clean the surfaces of any O-rings and packings that will come in contact with
components before use. Failure to do so may result in water leak against moisture or other problems.
(8) Check that all screws and nuts are properly tightened.
Failure to do so will result in water leak or other problems.
