4 Device assembly / installation
NOTE!
• If the tube is mounted on the same side as the tonometer, the
tonometer stop (5) must be fixed on the end of the tube.
• If the tube is left on the slit lamp permanently, the selectable relief
springs (10) must be reset (See instruction manual for the BQ 900
slit lamp)
• Tighten the control knob (12) on the cross slide to block the microscope arm and
the screw to block (13) horizontal movements.
• Loosening the bayonet joint (11) on the microscope (caution, hold the
microscope tight!) enables the stereo-microscope to be dismantled and the
beam splitter to be mounted.
• Carefully mount the stereo-microscope on the beam splitter with the bayonet
joint.
• Loosen the lid mounted on the side of the beam splitter (14).
• Hold the second observer tube in accordance with the figure. Align the groove

5 Commissioning
Following installation the device will be immediately ready for use; no further
measures are required.
6Operation
NOTE!
The eyepiece (3) must be set according to the refraction of the co-
observer.
6.1 Setting the viewing height (Second observer tube long)
The second observer tube can be turned around the horizontal axis coming laterally
out of the beam splitter. This enables the viewing height in the eyepiece to be varied
so that the second observer can look into the eyepiece at a freely adjustable
inclination angle.
FORBIDDEN!
The viewing height should not be adjusted during the examination, as
the patient or person carrying out the examination could be injured.
To adjust the viewing height, the release button (9) must be released first of all. To
do this, the elbow at the side of the beam splitter must be held so that the thumb is
positioned on top of the release button. To stabilize the slit lamp, the other hand
should be used to support the tube. Press and hold the release button and turn the
tube about the horizontal axis on the beam splitter. When the desired inclination
angle is reached, release the release button and turn the tube carefully until the next
engaging point is reached.

the viewing height of the second observer. The image is uprighted by adjusting the
twist grip (8).

Decommissioning is not required. However, we recommend dismounting the second
observer tube (long) after use in order to prevent accidental impacts.

9.1 Device inspection
The following procedure should be used to check that the second observer tubes
are working correctly:
• Insert the test rod into the radial movement bearing, whilst at the same time
aligning the surface to the microscope at a right angle.
• Set the slit length to 8 or 14 mm.
• Set the illumination intensity to 50%.
• Set the magnification in the microscope to max.
• Set the eyepieces in such a way that the test rod is in sharp focus. In doing so,
turn the ocular from the (+) to the (-) side.
• For all magnifications, the structure of the test rod must be shown in sharp
focus.
• In the second observer tubes, the same area must also be in sharp focus at all
magnifications
9.2 Servicing
To guarantee a long service life, the device must be cleaned weekly as described
