1.6 Light toxicity
WARNING!
• The light from this instrument may be dangerous. The risk of eye
damage increases with the radiation period and number of pulses.
Exposure at maximum output of longer than 90 seconds with the LED
illuminationand90pulseswiththeashsourcewillexceedthehaz-
ard guideline value.
• Using a 90 D lens reduces the exposure time to 9 seconds and the
number of pulses to 10.
NOTE!
• The radiation times and number of total pulses of all light sources are
cumulative.
• If the intensity of any of the light sources is reduced to 50% of the
maximum intensity, the illumination time or number of pulses to reach
the guideline value for radiation for the light source in question is dou-
bled. This linear relationship can be used to determine the illumina-
tion time to reach the guideline value for radiation for the combination
of slight sources at various brightness settings.
• The guideline value for the evaluated irradiation of the retina is 10 J/
cm2.
• Nevertheless, we recommend keeping the intensity of the light reach-
ing the patient's retina to the minimum possible for the respective di-
agnosis. Children, aphakes 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
speciallyappliesiftheretinahasbeenphotographedwithaashbulb
in advance.

2.6 LED illumination
• The LED illumination head is made up of an LED illumination unit, a power sup-
ply, an optical light guide set for periphery or background lighting and an illumina-
tion control.
• The two-core connection cable between the power supply and illumination head
transmits both the supply current for the LED as well as signals for communica-
tion between the power supply and illumination.
• The light intensity of the slit and periphery/background illumination can be regulat-
edcontinuously(withoutincrements)usingtheilluminationcontrollers.Thesecan
be connected using a longer connection cable on the PS-LED power supply.

3.2 Power supply on third-party tables
• Connect all cables; if necessary, use a cable tie to relieve the tension on the pow-
er cable.
• Fasten the PS-LED power supply with 4 screws.
• Connect the multi-core plug connection between the head rest and the instrument
table.
• Connect the main lamp cable to the upper part of the illumination unit.
WARNING!
• Care must be taken when mounting the guide rail and head rest to
ensure that there is no electrical connection to any metal part of the
table. Otherwise, it will be necessary to attach a ground conductor to
the head rest.
• The power supply must be connected with a ground conductor in any
case!
• Cables must not be trapped as this can cause a short circuit!
• Work on cables or device parts which are in connection with the
mainsmayonlybeconductedbyqualiedpersonnel.
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(27)toitslowestpositionandthenslackenitslightlybya
quarter turn. Swivel the microscope and illumination to the side.Apply 1-3 springs
depending on the accessory.
3.5 Switching on the compensation facility
Turnanticlockwiseuntilthescrews(12)arecompletelyreleased.
3.6 Switching off the compensation facility
Turnthescrews(12)clockwiseuntilyoumeetresistance.Verifywhetherthemicro-
scope arm springs back downwards if you push it upwards with your hand. This will
only happen 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 control
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

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(66)inplaceoftheprotectivecover(67)andturnitsblack
projection surface at a right angle to the microscope axis. Return the
illuminationandmicroscopetothecentralposition(0°).
Insert the 12.5x eyepiece with double crosshair into the right eyepiece mounting in
the binocular tube. The depth of the double crosshair on the reticle corresponds to
thelm/chiplevel.Thesettingisperformedfromthe(+)sideatlowmagnication

• Each eyepiece should be set individually by turning the knurled ocular refraction
ring with dioptre scale until the projected slit can be seen in focus. The setting is
performedfromthe(+)tothe(-)sideatlowmagnication.
• Theslidingoccluders(68)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 selected such 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 objectionable radiation.
• The lamp must be switched off after every examination.
5.3 Operating the instrument
WARNING!
The device must be switched off after every use. Otherwise there is a
risk of overheating when a protective dust cover is employed.
NOTE!

WARNING!
Pot cables may only be used in conjunction with an IC 01 illumination
module and a PS-LED power supply. Only connect the illumination
control to devices intended for this purpose!
5.10.1 Reduced operation
In order to ensure that the light sources will have a long service life, the power of
the periphery/background illumination is reduced somewhat once the maximum op-
erating temperature has been reached. Full power can be used again after a short
period of time for it to cool down. This operating state is only reached if both light
sources are switched on together for a long period of time.
NOTE!
The LED illumination can be switched off with the illumination control.
The device power supply remains switched on and the switch illumi-
nates green. To switch the system off completely, the rocker switch
must be set to the 0 = 'OFF' position. This results in double-pole dis-
connection from the mains.
