Connecting the fibre optics
Please ensure that the correct adapter (Storz) is fitted to your fibre optics. You can also purchase the appropriate adapter from us providing
details of the manufacturer of the fibre optics (see replacement parts section 9).
Caution: Parts within the light source can be damaged by using an inappropriate adapter. A false adapter always
leads to light loss.
Connecting the potential compensation lead
Connect the potential compensation connection to the central potential compensation of the operating theatre or the instrument trolley with a
suitable cable.
Important operating information
After switching on the light source and the lamp has started up, the instrument should remain switched on for at least 1/4 hour. A shorter peri-
od considerably reduces the service life! After switching off the light source, it may be switched on again immediately.
Possible maintenance and cooling down periods are not required. After all cables have been connected, switch on the instrument at the mains
switch. The green light inside the switch lights up and the lamp goes on immediately. You may now work with the light source. Adjust the requi-
red brightness with the knob (2). No further adjustments to the instrument are necessary during operation.
6. Repairs
The information contained in this chapter are only intended for authorised specialist personnel who have received instruction and have a grasp
of the knowledge required and the safety precautions for the repair of electronic instruments.
The manufacturer accepts no liability for repairs and modifications, which are carried out by non-authorised specialist personnel.
Upon request, the manufacturer will provide available circuit diagrams, detailed replacement part lists, descriptive information, adjusting
instructions and other documents, which are of use to the correspondingly qualified personnel of the user who have been authorized accor-
dingly by the manufacturer for the repair of instrument parts, which are described by the manufacturer as repairable.
The availability of technical documents about the instrument does not in itself represent an authorisation by the manufacturer for technically
trained personnel to open or repair the instrument. Excluded in this respective are the interventions described in the text of these operating
instructions.
Exchanging the mains fuse
The mains fuse is located at the rear of the instrument, on the right of the mains connection in a small fuse compartment.
• Pull out the mains plug!
• Loosen the fuse compartment by freeing the clips on both sides of the compartment with a pointed object and pull the
compartment out.
• Remove the fuses.
• Check the fuses
• Burnt out fuses can be recognized by blackening of the glass bulb, a visible break in the fuse wire or, if appropriate, by
measuring the continuity of the fuses with an ohmmeter.
• Replace the respective fuses.
• Put the fuse compartment back into the instrument
Now put the instrument back into operation. If you have replaced a defective fuse with a new one and it burns out again, this points to a fault
in the instrument. In such cases, send the instrument to us for checking.
Exchanging the lamp
Changing the lamp
The average service life of the lamp is approx. 500 hours. After this service life period has expired, the light output decreases markedly, the
colour spectrum changes and it cannot be ensured any longer that the lamp will ignite properly.
In order to assure proper operation, it is essential that the lamp is exchanged after the operating life has been reached.
The lamp is a high-pressure lamp filled with non-poisonous xenon gas. The combustion chamber is also under high pressure in the cold
state and can explode, if handled improperly.
For this reason, the lamp should only be changed by trained expert staff and while observing the following safety instructions !
• When working directly with the lamp, always wear protective safety glasses and leather gloves which also protect the arteries of
the wrists.
• Always store the lamp in its original packaging when not in use, never let it lie around.
• Never bend the contact connectors, the electrodes or the electrode connections or subject the lamp to other types of mechanical
force.
• Return old, burned out lamps to the manufacturer in the original packaging for proper disposal.
• You can also dispose of the lamp yourself. In order to do so, the lamp must be demolished observing all safety precautions. The
concentration of xenon gas which escapes into the room presents no danger to health. The remains of the lamp can be disposed
of as special waste, the tungsten electrodes are to be disposed of with special recycling materials.
• Never place the burned-out lamp into the waste without demolishing it first.
If all safety precautions are followed, the lamp can be simply exchanged without presenting any danger, as follows:
