4. Safety Standards
The SOCT Copernicus system complies with all requirements of the directive 93/42/EEC (MDD -
Medical Devices Directive).
The SOCT Copernicus is Type B, Class I protection.
Usually SOCT Copernicus is a part of larger Medical System, which consists of many other medical
and non- medical devices. Medical system in general and all its components have to fulfil
requirements of IEC-60601 norm.
In order to comply with the IEC-60601 norm all non Medical Devices must be connected to the
Separating Transformer which is supplied with the SOCT Copernicus. By connecting the devices to
the Separating Transformer leakage current is reduced to a level which is in line with the IEC norm.
The Separating Transformer fulfils requirements of IEC-60601-1 norm 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 norm.
SOCT Copernicus is connected to computer using RS232 cable. This cable is electrically separated
using optocouplers. It provides additional safety, when computer and SOCT Copernicus 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 device providing even more safe solution.
No user serviceable parts inside SOCT Copernicus device. Light source is included inside device.
Removing of covers can be done only by authorized personnel.
The maximum power of light radiation available outside covers is
less than 750 (+3% -0,5%) microwatts providing safe operation of the device.
Objective lens is output of light.
SOCT Copernicus has been classified as CLASS 1 LASER DEVICE
SOCT Copernicus/SPOCT 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 diagram on page 13 can lead to electric shock
or damage the devices.
Prohibit connect any non medical or medical devices which are not including with SOCT
Copernicus system to the Separating Transformer e.g. lamp, vacuum cleaner etc.
The SOCT Copernicus must not be connected to the transformer, but directly to the mains socket.

Important !
1) If the whole Medical System has been installed by Manufacturer of SOCT Copernicus,
the manufacturer guarantees correct installation and compliance with all required
norms and directives.
2) In case when installation was made not by Manufacturer, Manufacturer of SOCT
Copernicus takes NO responsibility for any problems or risks that could be created by
incorrect connection and violation of safety standards.
3) Manufacturer of SOCT Copernicus takes no responsibility for incorrect medical
diagnose of results and takes no responsibility for the consequences of such incorrect
medical diagnosis.
4) Storage at excessively low temperatures, such as outdoors in winter , may result in a
delay during installation and subsequent shortening of the time available for training
by the Optopol Customer Service representative.
Warning !
Ignoring safety rules can lead to accidents.
1) If SOCT Copernicus and the whole Medical System have been installed by the
Manufacturer, the Manufacturer guarantees the proper installation and compliance
with MDD 93/42 EEC rules. It is customers’ responsibility to prepare the site.
2) Any computer system or device attached to SOCT Copernicus must be MDD compliant
or be plugged only to Separating Transformer. Devices which are not related with
patient examination (e.g. lamp, fan) cannot be connected to Separating Transformer.
3) Multiple portable socket-outlets shall not be placed on the floor.
Warning !
All activities that demand removing main body housing may be performed by qualified
personnel only.
Ignoring or disregarding the statements above may lead to danger of death or serious injury.

SOCT Copernicus 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 the
retina is then interferometrically analyzed by the device. The raw data is processed by a
computer to obtain images of retina cross-section.

7. Environmental Conditions
Operation:
Temperature in the SOCT room should ideally remain between 65 ºto 80 ºF, (18-27 ºC) both for
patient comfort and for optimum operation of the unit. Patients may feel discomfort when
temperature in the room is excessively high. Maximum operating temperature is 104 ºF (40 ºC) is
allowed.

8. Unpacking and Installation
NOTICE: Every transportation box is equipped with schockwatches. If any of the shockwatches is
broken, please contact Optopol and lodge the complaint to the carrier.
1. SOCT Copernicus set consists of the following components:
2. SOCT device with CL cable.
3. RS232 communication cable.
4. Coaxial synchronization/video cable.
5. PC Computer with preinstalled software.
6. The power supply cables and computer accessories.
8.1 Unpacking SOCT Copernicus
This section describes ho to unpack the device shipped from a factory. The SOCT Copernicus is
shipped in a special box, which protects it from mechanical damages during transport. Figures below
show how to unpack SOCT from this box. The box has got four latches shown in detail in pictures
below.

Now one can remove the cover by lifting it up gently. The SOCT’s Copernicus four legs are locked at
two metal rails by clamps. There are only two removable clamps at a side. First remove screws from
the clamps and then remove metal holders. This operation is shown in a figure below.
Now shift SOCT Copernicus to the left and then lift it up. Put the SOCT on the flat stable
table.
Important!
It's strongly recommended to wait at least one hour before turning the device on for the first time
after delivery. It's mostly important in case where the delivery was made during low outside
temperatures or high humidity.
After unpacking one should check the whole set for any mechanical damages, cables
damages, etc. In case any damage is found, don't connect the device and contact your
local distributor.
