Section 1
GENERAL
The Dutch Ophthalmic Research Center (D.O.R.C.) is an innovative company that is involved in
research, development and manufacturing of high quality instruments and equipment for ophthalmic
surgery.
All D.O.R.C. products have been clinically tested before they were released to the ophthalmic
surgeon.
D.O.R.C. plans to be able to be of service to the ophthalmic profession with even more innovative
helpful products, for many years to come.
This Service manual should be helpful to you, while working with your D.O.R.C. MICRO
DIATHERMY SYSTEM. Of course we are willing to listen to any possible suggestions that make
the Service Manual even more useful.

WARNINGS
A warning:
Indicates a potentially harmful situation to yourself or others.
Electric shock hazard
The Diathermy system contains high voltage circuits.
After performing any repair, calibration procedure performs a final electrical safety check
and leakage current test.
Unplug the power cord before cleaning or servicing the unit. Should the power cord or plug
become cracked, frayed broken or otherwise damaged, it should be replaced immediately.
Do not touch any exposed wiring or conductive surface, whilst the cover is off and the unit
energized. The voltages present, when electric power is connected to the Diathermy system,
can cause injury or death.
Never wear a grounding wrist strap when working on a energized unit.
The operator should now perform any servicing except as specifically stated in the
Instruction Manual.
Do not, under any circumstances, perform any testing or maintenance on medical
instruments, while they are being used to monitor a patient. Always turn the Diathermy
system off before cleaning.
Explosion hazard
Never use this Diathermy system in the presence of flammable anaesthetics.

CAUTIONS
A caution:
Indicates a condition that may result in equipment damage or malfunction.
Electrostatic discharge through the printed circuit boards will damage the components of the
Diathermy system. Handle all circuit boards (replacements and defective) by their non-
conductive edges and use anti-static containers when transporting them.
Before servicing the equipment, ground yourself and the tool to discharge any accumulated static
charge by wearing a static control wrist strap.Use hospital-grade grounded receptacle only.
Servicing of this product, in accordance with the Service Manual, should never be undertaken in
the absence of proper tools, test equipment and the most recent revision of the Service Manual,
which must be clearly and thoroughly understood.
Do NOT apply tension on the line cord.
Check rear panel voltage setting before connecting the Diathermy system to AC main power.
NEVER IMMERSE THIS UNIT IN LIQUID !!
