Hygienic Reprocessing - HEINE OMEGA 600 Mode D'emploi

Charging via charging case CC1
Use the charging case CC1 to charge the battery CB1 (10) of the
device. Turn the OMEGA 600 off. Remove the battery CB1 (10) from
the battery compartment (8) and insert it into the charging case CC1.
The charge status indicator of the charging case CC1 is located on
the upper side of it.
Make sure that no foreign objects come between the battery
CB1 (10) and the charging case CC1. When using the charging
case CC1 to charge the battery CB1 (10), make sure that the
charging case CC1 is not contaminated in any form.
The setting up and operation of the charging case CC1 is described
in a separate instruction of use.
Charge status indicator (7)
The charge status indicator (7) of the device is located on the
battery compartment (8) of the device.
The charge status indicator (7) is automatically activated when the
device is switched on.

Operation
Initial optical set up
Remove the protective dust cover (16) and place aside for reattaching
after the examination. Unlock the adjustment lever (5) so that the
optics unit (13) is free to move. Place the instrument on your head
and adjust the height and circumference by means of the width
adjustment (1) and height adjustment (2), respectively, until a
comfortable fit is achieved. The rear part of the headband can be
adjusted according to personal preference. Adjust the optics unit
(13) to a position as close as possible to your eyes and centred to
your face, then lock it in this position using the adjustment lever (5).
Adjust the eyepieces (19) horizontally to match your own personal
pupillary distance. The initially mounted eyepieces (19) incorporate
+2D lenses that can be exchanged with neutral lenses (0D). Switch
on the light by turning the brightness control (6) clockwise. You
should now see the illumination spot being centred to your view at
a distance of about 40 cm and you should be able to observe a
pencil-sized object sharply focused at this distance. If you cannot
focus on the pencil-sized object, you may have to adjust your
distance to the object. Alternatively, you may try exchanging the
initially mounted eyepieces (+2D lenses) (19) with the eyepieces
containing neutral lenses (0D). More details on how to interchange
the eyepieces (19) can be found in the section "Maintenance". If
the illumination spot is not centred, you can adjust it vertically by
twisting the illumination height adjustment (15) and you can adjust
it horizontally by simply rotating the whole instrument slightly to the
desired side. If a proper alignment has not been achieved, repeat
steps as above. Correct adjustment of eyepieces (19) which match
your own personal pupillary distance is particularly important when
examining through small pupils. Each user should adjust the setting
to match their own personal pupillary distance.
Setting the brightness
Adjust the brightness by using the brightness control (6). To increase
the brightness, turn the brightness control (6) clockwise. Once you
reach a latch, you are operating in the highest brightness range
in standard mode. If you turn the brightness control (6) further
clockwise and over the latching mechanism, you switch into the
visionBOOST setting. When the end stop is reached, the highest
brightness range in the visionBOOST is operating.
To decrease the brightness or to turn the device off, turn the bright-
ness control (6) counterclockwise. When the end stop is reached,
the device is turned off.
It is recommended to start with the lowest possible brightness and
then increase as required for the examination. The visionBOOST
might be used for the examination of patients with media opacities,
e.g. cataract.
Aperture selection lever (14)
Three different aperture sizes and a diffuser aperture can be
selected by means of the aperture selection lever (14). The choice
of aperture depends mainly on the size of the patient's pupil. The
diffuser is useful for the examination of the periphery.
Filter selection lever (18)
In addition to the unfiltered option, the filter selection lever (18) can
be used to select an interference red-free filter, a blue filter or a
yellow filter. These are switched into the illumination beam.
The interference red-free filter can be used to view changes of the
retina (e.g. new vessels or retinal nerve fiber layer defects) and
highlights whitish portions of the retina, if present.
The blue filter can be used to do fluorescein angioscopy.
The yellow filter can be used to reduce discomfort for the patient
and photochemical hazard by reducing blue light.
Stereoscopic adjustment lever (17)
This feature ensures the best possible stereopsis for any pupil size
and from any observation angle possible (e.g. peripheral view). When
examining a dilated pupil head on, it is recommended to move the
stereoscopic adjustment lever (17) into the forward position. When
examining the periphery of the eye or in case of undilated pupils, it
is recommended to move the stereoscopic adjustment lever (17)
towards the side position (turn to your left). The stereoscopic
adjustment lever (17) can be positioned anywhere between these
two settings to select the optimum 3 dimensional view in any
possible situation. The illumination beam can be adjusted vertically
by the illumination height adjustment (15).
Use of the flip-up function
While wearing the instrument, the optics unit (13) can be folded
up into the rest position. To bring the optics unit (13) back into the
working position, simply fold it down again. There is no need to
readjust the instrument.
Teaching mirror (TM1)
The TM 1 can be magnetically attached to the optics unit (13)
instead of the dust cover (16).
To be able to follow the examination of the main observer, the
secondary observer stands next to the main observer and looks
into the TM1 attached to the device from the side. The observation
beam is split by the divider mirror, which approximately halves
the brightness of the image for both the main and the secondary
observer.
The TM1 is intended for training purposes only.

Maintenance
There is no regular maintenance required. The following maintenance
should be done outside of the patient environment (at least 1.5 metres
from the patient or patient support pursuant to IEC 60601-1, see
Fig. 5) and when deemed necessary.
Changing the position of the brightness control (6)
The position of the brightness control (6) can be fitted on the right
or left side onto the preferred socket for brightness control (4).
To remove the brightness control (6), turn the device off and pull the
dial out to gain access to the retaining screw. Remove the screw to
detach the holder by using the enclosed offset screwdriver (see Fig. 6).
Gently pull out the holder off the socket for brightness control (4)
paying attention to the retaining clips. Remove the cover from the
other socket for brightness control (4) and insert the holder by
aligning the retaining clips. Insert the screw and tighten hand tight
with the enclosed offset screwdriver (see Fig. 6). Reinsert the
brightness control (6). Cover the spare socket for brightness control
(4) with the cover. To activate the brightness control (6), remove the
battery CB1 (10) from the OMEGA 600 or unplug the OMEGA 600
wired. Once power is reapplied the brightness control (6) will be fully
functional.
