Setting up the HEINE OMEGA 500
Operation with the HEINE mPack
To operate the HEINE OMEGA 500
connect the short cable (24) from the HC50 brightness control (14) to the
connecting cable (Cinch) and secure it in the cable guide (21). Connect the
connecting cable (Cinch) to the HEINE mPack
the brightness on the instrument with the HC50 brightness control (14), (Fig.
Operation with the mPack UNPLUGGED:
To operate the HEINE OMEGA 500
remove the cover from the rear segment (23) on the headband. To do this, slide
the segment cover from the headband in the direction of the arrow ( Fig.
Next, fit the HEINE mPack
headband with your left hand and using your right thumb, slide the HEINE
mPack UNPLUGGED to the left until it latches audibly. Connect the short cable

(24) from the HC50 brightness control (14) to the HEINE mPack
Switching on and adjustment of brightness are carried out by means of the
rotary knob on the HC50 brightness controller (14), ( Fig.

Operation from other power sources (EN20, EN30, HC Converter):
For operation with power sources other than mPack or mPack UNPLUGGED
connect the long cable by means of the cable clip, after having clicked the
cable clip into the rear segment of the headband. On/off switching and
brightness control is by means of the power source ( Fig.

Basic Adjustments:
Switch the instrument on by means of the rotary knob (brightness control) on
the HC50 brightness controller. Aperture wheel (7) and filter wheel (6) should
be rotated upwards to select the large aperture with white light. Control (11)
should be in the middle position.
The beam control (9) should be in the mid-position. Slide the eyepieces into
position to match your P.D. or select the mid-position on the scale.
Control Locks:
The aperture and filter controls can be locked into position by means of the
lock (8) to avoid unintentional operation.
Aperture Control:
3 different aperture sizes and a diffuser aperture can be selected by means of
the aperture control (7). The choice of aperture depends mainly on the size of
the patient's pupil. The diffuser is useful for photophobic patients and the
examination of the periphery.
Filter Control:
The filter control (6) can be used to select an interference red-free filter, a blue
or a yellow filter which can be introduced into the illumination beam.
Synchronized adjustment of Convergence and Parallax:
This feature ensures the best possible stereopsis and image quality for any pupil
size by simultaneous adjustment of the observation and illumination beams. For a
dilated pupil, move the control (11) underneath the instrument to the large circle
position.
For a small pupil, move the control to the small circle position. The control (11)
can be positioned anywhere between these two settings to select the optimum
parallax and stereopsis (convergence) for any pupil size. The illumination beam
can be adjusted vertically by the control (9).
Teaching Mirror:
The optional teaching mirror can be slid onto the fixture (10) of the optics.
