Instruction manual SDI 4 (G/54320/0109/en) 5 / 21
4 Functional Description
The SDI 4 (Stereoscopic Diagonal Inverter) before you reinverts images, e.g. that of a
BIOM 4 or a wide angle contact lens.
SDI 4e/4c
The image inversion provided by the SDI 4e/4c can be turned on and off via a hand-held
pushbutton or an optional foot switch in less than a second.
If electrical adjustment is impossible for any reason, you also have the option of aligning
the optic system mechanically by hand with the adjustment knob.
You can recognize the position of the optical system by the indicator light. If it is yellow,
the image inversion feature is activated.
If adjusting mechanically by hand, turn the adjustment knob clockwise until you feel it
click into position. The indicator lights up shortly before the final position is reached.
Only SDI 4c
If the SDI 4c is used together with the BIOM 4c, the image inverter is controlled by the
position of the BIOM 4c. A position switch on board of the BIOM 4c activates the SDI 4c,
while being swung into the vertical working position.
If the BIOM 4c is out of the beam path, the SDI 4c is automatically switched off.
Independently the SDI 4c can be controlled via the combi- foot switch.
SDI 4m
Image erection with the SDI 4m can take place only by mechanical adjustment with the
hand-turned knob. You can recognize the position of the optical system by the indicator
in the transparent glass. It is centrally located on the front of the SDI 4m, just to the left
of the adjustment knob. If the transparent indicator is completely yellow, this means that
the image inversion is not taking place at the moment.
5 Proper Usage
These stereoscopic diagonal inverters SDI 4m/4e/4c reverse the picture of indirect moni-
toring systems (BIOM 4, wide-angle contact lenses) true to during minimal invasive pos-
terior segment surgery of the human eye.
The device should be used only by physicians and OP personnel who have been corre-
spondingly trained and who have the training, knowledge, and practical experience to en-
sure appropriate handling.
The SDI 4 is intended for use with correspondingly designed surgical microscopes in hos-
pitals, clinics or other places where human medicine is practiced.
Such surgical microscopes must be specifically designated by OCULUS Optikgeraete
GmbH as being compatible.
Only operate the device using original accessory parts supplied by OCULUS Optikgeraete
GmbH , and when the device is in technically correct working order.

6 Operation
6 / 21 Instruction manual SDI 4 (G/54320/0109/en)
Use only the net plug adapter from OCULUS Optikgeraete GmbH as a power supply unit.
If the microscope has sockets designated by the microscope support manufacturer as
conforming to IEC-601, these may also be used.
Please also heed to safety instructions listed above.
6Operation
6.1 Preliminary steps
Please remove the plastic carrying case from its packing and dispose of the packing
properly.
The sterilizable rubber cap is to be cleaned, disinfected and sterilized before the first and
each further application.
Please keep the plastic carrying case and the securing device in a safe place even after the
unit has been assembled, since subsequent longterm storage or return for servicing or re-
pairs as well as shipment of the unit can best take place only in the plastic carrying case
with its special lining and the securing device.
As part of an optical unit, the SDI 4, like the surgical microscope, should be handled with
care and should not be subjected to shocks, blows, soiling or high temperatures (above
40° C).
Before assembling the unit, remove both protective dust covers and the securing device.
The upper protective dust cover can be removed by unscrewing the hexagon socket set
screw, and the lower one can be simply pulled downwards. Store these as well for best
subsequent dust protection should you disassemble the SDI 4 at a later date.

6.2 Attachment to an operating microscope
Note
It is advisable that two persons carry out the installation or the dismantling of the SDI 4
at an operation microscope.
fig. 6-1: Before the installation of the SDI 4
ÎAlways take care when mounting or removing the SDI 4 that none of the optics in
the beam paths become soiled.
ÎWhilst protecting the binocular tube from falling down, please unscrew the locking
screw on the main body of the microscope (1).
ÎTypically, the SDI 4 is mounted below the beam splitter.
Remove the binocular eyepiece and the beam splitter from the main body of the mi-
croscope.
On some microscopes the beam splitter is permanently built into the microscope; in
this case, the SDI 4 must be mounted above the beam splitter.
ÎNow place the flange of the SDI 4 into the dovetail receptacle of the main body of
the microscope. Check that the SDI 4 is properly seated before carefully tightening
the locking screw of the main body of the microscope. When properly mounted, the
SDI 4 should not wobble.
Please make sure of this before attaching the other microscope components.
