IMPORTANT
The Olympus Electrosurgical Unit PSD-10 has been designed for endoscopic electrosurgery (coagulation,
polypectomy, sphincterotomy, etc.) in conjunction with Olympus fiberscopes that are applicable to
electrosurgery, Olympus electrosurgical accessories and light sources. Do not use the equipment
for any purpose other than its intended use.
Please read this entire manual carefully before using the equipment in order to acquaint yourself
with the proper care and handling of your new electrosurgical unit. Then prepare and inspect the
equipment following these instructions.
Safety precautions must be exercised when handling electrical equipment to prevent operator/
patient shock, fire hazard and equipment damage.
If you have any questions concerning the material contained in this manual or concerning the
operation or safety of the equipment, please contact your Olympus representative or the nearest

FEATURES AND MAIN SPECIFICATIONS
1-1 Features
1. Simplified pre-procedural test, using a Check Lead, of the power output of
the PSD-10 alone as well as that of the entire electrosurgical system includ-
ing the endoscope and endoscopic electrodes. Test results confirmed by
TEST “OK” or “FAULT” indicator lights on the front panel.
2. Push-button selection of CUT, COAG or BLEND current. Output power is
controlled by a single-pedal footswitch.
3. The connection monitor circuit detects loose or inadvertent misconnection
of cords or broken wires in the S-P cord (Safety cord and Patient cord).
If any irregularity is present, the monitor activates an alarm and inhibits
output (current is not delivered when the footswitch is depressed) to ensure
safety of the procedure.
4. The feedback ratio monitor scans the entire circuit when the footswitch is
depressed. If excessive leakage current is present, the output is inhibited to
ensure safety of the procedure.
5. Flat switches and display panel can be easily wiped clean.
6. Compact, lightweight and portable.

Output check • When the Check Lead is connected and the footswitch
depressed, either the “OK” or “FAULT” light will come
on.
• Checks the PSD-10 or the entire electrosurgical system.
The entire electrosurgical system cannot be tested when
using PSD-10 in combination with CD-3U/L or CD-40/L.
’Monitors Connection monitor Detects defective connections of cords and broken wires
in the S-P cord, and activates:
• A warning light (P-cord or S-cord symbol), a warning
buzzer, and inhibits output.
Feedback ratio monitor Computes return current/delivered current ratio. If the
ratio is less than a preset value, it inhibits output.

1-3 Safety Precautions
The PSD-10 should be used only in a medical facility under the supervision of a
trained physician.
The PSD-10 is designed (floating) to function integrally with insulated patient attachments
(active electrode and patient plate) to prevent operator/patient shock. To prevent shocks
which may be caused by leakage current from other apparatus applied to the patient,
endoscopes and cameras used with the PSD-10 should not be grounded.
The endoscopist and his assistant should wear rubber handgloves as an added precaution.
When using a camera (except the SC16-10) an insulating hood should be attached
to the camera’s eyepiece.
The enclosure of the PSD-10 must be grounded securely and effectively. Do not
defeat the line cord ground connection.
The PSD-10 should never be applied to the heart directly.
Never install and operate the PSD-10 where there is a risk of flammable gases.
Should any irregularity or abnormality be suspected during operation, immediately
stop the use of instrument and turn OFF the power switch.
Keep liquids away from all electrical equipment to prevent operator shock and instrument
damage. Do not use the PSD-10 if spilled fluids have entered the unit.
Please investigate the possibility of electronic interference for other electromedical
equipment in conjunction with the PSD-10 prior to use.
Do not install the patient plate adjacently to an artificial bone (metal), etc.
Non-Controlled Document

Keep adequately away from cords of electric scalpel (scalpel holder, scalpel cord and
patient plate cord), scalpel main body and cords, main body of other electromedical
equipment.
Do not loop cords of electric scalpel (scalpel holder, scalpel cord and patient plate
cord). Do not contact these cords with the patient or metallic portion of an operating
table, etc.
The PSD-10 should not be used in conjunction with electrical apparatus whose safety
against leakage current is not guaranteed.
Radio-frequency and spark discharge “noise” may adversely affect other electro-medical
equipment being used in the proximity.
Do not apply the electric scalpel to the patient who has a pacemaker in his body.
The use of a radio-frequency noise filter in monitor electrode lines may reduce interference.
Patient monitor electrodes must be placed as far away as possible from the operative
field.
Needle type electrodes should not be used as they increase the risk of burns.
To prevent instrument damage, the active electrode and the patient plate should not
be short-circuited.
Do not activate the electrode for an extended time when it is not touching the target
tissue.
The PSD-10 should be used in accordance with the operating environment specified
in 1 – 2 Main Specifications; otherwise improper performance, compromised safety or
instrument damage may result.
Repairs should be carried out only by an Olympus Service Center.
