DANGER!
Never use the device in potentially explosive environments where vola-
tile solvents (alcohol, petrol, etc.) and flammable anaesthetics are in
use.
WARNING!
The device must be switched off after every use. Otherwise there is a
risk of overheating when a protective dust cover is used.
NOTE!
This equipment must only be operated by qualified personnel. The
owner is responsible for their training. This device may only be used
in accordance with the instructions in "Purpose of use".
1.6 Light toxicity
WARNING!
As extended, intensive illumination can damage the retina, the use of the
device in the examination of the eye should not be prolonged unneces-
sarily. The illumination of this slit lamp emits a radiation in the range be-
tween 400 and 750nm. The retinal dose for a photochemical risk is com-
posed of the product of the radiance and the exposure time. If the radi-
ance is halved, the time until the exposure time limit value is reached will
double accordingly. To date, no acute, optical radiation hazard has been
detected in slit lamps. Nevertheless, we recommend keeping the intensi-
ty of the light reaching the patient's retina to the minimum possible for the
respective diagnosis. Children, people with aphakia and people suffering
from eye conditions are most at risk. An increased risk may also occur if
the retina is exposed to the same or a similar device with a visible light
source within 24 hours. This applies, in particular, if the retina has been
photographedwithaashbulbinadvance.Thelightfromthisinstrument
may be dangerous. The risk of eye damage increases with the exposure
time. An exposure time with this instrument at maximum intensity of lon-
ger than 131 seconds exceeds the guideline value for a risk.
1.7 Disinfection
NOTE!
The device does not need to be disinfected. For more information on
cleaning, please refer to the 'Maintenance' section.

• Fix the breath shield (27) in place by fastening the knurled screw (28) on the in-
side of the bearer arm.
3.2 Power supply
NOTE!
Observe the respective Haag-Streit instructions for use. (For further
information, please contact your
Haag-Streit dealer).
This device must only be operated with PS-LED and PS-LED HSM 901
HS power supplies and the RM02 release module.
•
•
3.3 Instrument base with weight compensation facility
The weight of additional accessories mounted on the microscope can be compen-
sated using counterbalance springs. This keeps the height adjustment of the slit
lamp easy.
3.4 Setting the weight compensation facility
Turn the control lever (35) to its lowest position and then loosen it slightly a quarter
turn.Turnthemicroscopeandilluminationtotheside.Apply1−3springsdepend-
ing on the accessory.
3.5 Switching on the weight compensation facility
Turn anticlockwise until the screws (20) are completely released.
3.6 Switching off the weight compensation facility
Turn clockwise until you meet resistance. Verify whether the microscope arm
springs back downwards if you push it upwards with your hand. This will only hap-
pen if the load is already at maximum. Generally, as many counterbalance springs
should be deactivated as necessary until this spring action occurs. The weight
compensation facility is set correctly once the illumination and microscope with the
mounted accessories weigh slightly more than the counterbalance springs.
3.7 Regulating the clearance of the slit width controls
The small screw in the center of the right control knob (A)
allows you to regulate the friction of the turning movement
of these adjusting knobs. Turning it slightly to the right (in)
makes it harder, turning it left (out) makes it easier. It should
at least be set so hard that the slit cannot close on its own. A A
4. Commissioning
The device can be switched on and off with a mains isolator on the power supply.
The green lamp in the rocker switch lights up when the device is switched on.
4.1 Switching on the appliance
• Connect the power supply to the mains and press the rocker switch. The green
lamp in the rocker switch lights up when the appliance is switched on.
• Set the knob on the illumination control to a position between '1' and '10'.
5. Operation
5.1 Setting the eyepieces
NOTE!
Theeyepiecesmustbeindividuallysetpriortotherstexaminationin
accordance with the refraction of the examiner. Insert the provided fo-
cus test rod (37) in place of the protective cover (38) and turn its black
projection surface at a right angle to the microscope axis. Return the
illumination and microscope to the central position (0°).

• Each eyepiece should be set individually by turning the knurled ocular refraction
ring with diopter scale such that the projected slit can be seen in focus. The set-
tingisperformedfromthe(+)tothe(-)sideatlowmagnication.
• The sliding occluders (39) are used to set the correct working distance for the ex-
aminer from the eyepiece.
• Examiners who do not wear glasses: Pull the occluders out as far as they will go.
• Examiners who do wear glasses: Push the occluders in as far as they will go.

5.2 Preparing the patient
• In order to attain a solid basis for the forehead and chin to rest on, the table height
should be set so that the patient sits bent over forward.
• To ensure that only the part of the eye being examined is illuminated, the slit
height should be set accordingly in order to avoid distracting streaking of light.
• Parts which come into contact with the patient should be cleaned with a dry cloth
prior to every use.
• The lamp must be switched off after every examination.
5.3 Operating the instrument
WARNING!
The device must be switched off after each use. The risk of overheat-
ing increases if a dust cover is used.
• Use the turn screw (7) to set the chin rest (6) so that the patient’s eyes are at the
same height as the black mark (4) on the sides of the head rest.
• Set the eyepieces (26) in accordance with the examiner’s refraction by turning the
knurled rings and set the eye distance.
• Adjust the height of the slit lamp by turning the control lever until the light beam is
at eye level.
• Switch on the illumination by turning the switch on the power supply.
• Themagnicationofthestereomicroscopeischangedusingthemagnication
changer (13).
• The rigid control lever (35) gently inclined towards the examiner can be used to
push the entire device until the slit appears approximately focused on the cornea.
Thisinitialsettingisveriedwiththenakedeye.Finetuningisperformedbytilting
the control lever while observing via the stereo microscope (25).
• The slit width is set left or right with the rotating knob (19), as is the angle be-
tween the stereo microscope and illumination. The slit image can be set vertical-
ly, horizontally or diagonally as required by turning the illumination facility on the
handle (23) (locking points at 45°, 90° and 135°; stops at 0° and 180°; scale in
5° increments).
• To ensure that unimpeded binocular fundus examination is also possible at lateral
angles of between 3° and 10°, a short mirror (11) is used, the illumination turned
90° using the locking screw (23) and tilted in 5° steps using the latch (31), and
the illumination and microscope turned to the central position (0°).
• Front-lens glasses and contact glasses are used to examine the ocular fundus.
Diffuse illumination:
• A diffuse illumination is achieved by positioning the diffusor (12) upstream. This
enables overview monitoring and can be used for taking overview images with the
Imaging Module.
Indirect illumination:
• For observation in regredient light (indirect illumination), the centering screw (30)
isloosenedinordertomovetheslitimageoutofthecenterofthevisualeld.
Tightening the screw centers the slit image again.
Slit tilting:
• The latch (31) can be used to tilt the illumination in 5° steps. This creates an an-
gledlightbeamduringhorizontalslitorientation.Tiltingtheslitenablesreex-free
examination with contact glasses (fundus and gonioscopy) and magnifying glass-
es.

er supply remains switched on during this process and the switch lights up green.
To switch off the system completely, the rocker switch must be set to position 0 =
'OFF'. This creates a two-pole isolation from the mains.
NOTE!
Disconnect the power supply from the mains if you do not intend to use
it for an extended period of time.
