The Separating Transformer fulfils requirements of IEC 60601-1 standard for medical
devices which has not application part.
The Separating Transformer supply the power for non medical devices connected to
electric not grounded mains in room.
The Separating Transformer can be installed in patient environment in accordance with IEC
60601-1 standard.
SOCT Copernicus HR is connected to computer using USB cable. This cable is electrically
separated using optocouplers. It provides additional safety, when computer and SOCT
Copernicus HR device are connected to two different power supply sockets with different
ground potentials. Video signal and synchronization signal are transferred to computer
using coaxial cables, which are electrically separated from SOCT Copernicus HR device
providing even more safe solution.
SOCT Copernicus HR system can be connected only to power supply socket
equipped with properly connected grounding pin.
Please note that only the PC, monitor and printer are to be connected to the Isolating
Transformer. Connecting non medical devices in other way than in point 7.3 Device
connection diagram can lead to electric shock or damage of the devices.
Prohibit connect any non medical or medical devices which are not including with SOCT
Copernicus HR system to the Separating Transformer e.g. lamp, vacuum cleaner etc.
The SOCT Copernicus HR must not be connected to the transformer, but directly to power
supply socket equipped with properly connected grounding pin.

service staff.
During the whole period of use, SOCT Copernicus HR does not need any special maintenance
procedures. The outside surfaces of device should be cleaned using mild cleaning solvents.
Only a soft cloth can be used for cleaning. During cleaning it has to be assured, that no water gets
inside the device.
The forehead rest and chinrest are parts that routinely have contact with patient. The forehead and
chin rests should be cleaned between each examination with an alcohol prep swab.
The main lens of the device should not contact the patient's eye. It comes with a lens cap to cover it
when not in use. Lens may touch the eyelashes during normal use. You should clean it to remove
dust and oily smudges occasionally to ensure a true tomogram images are obtained. You may use an
alcohol prep swab or cotton swab dipped in isopropyl alcohol. (You may use dedicated optical lens
cleaner.) Wipe dry with a soft, non-lining cloth or tissue. If the lens inadvertently contacts the
patient's eye, clean it before proceeding with the examination. Periodically one has to check if there
are no mechanical damages to the device, damages to any of the cables and fuses.
5. Device Overview.
SOCT Copernicus HR uses spectral domain optical coherence tomography method to obtain
3-dimensional cross-section images of a human retina. The device produces a laser beam, which is
focused on a human retina. The light that reflects from internal structures of a retina is then
interferometrically analyzed by the device. The raw data is processed by a computer to obtain images
of retina cross-section.
