1.5 Operation, environment
DANGER!
Never use the device in potentially explosive environments where
volatile 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.
• This device must not be operated near of high frequency surgical
equipment and the radio frequency shielded room of a medical
electrical system for magnetic resonance imaging, where the
intensity of electromagnetic disturbances is high.
• Portable radio frequency communications equipment (including
peripherals such as antenna cables and external antennas) should
be used no closer than 30 cm (12 inches) to any part of the device,
including cables specified by Haag-Streit. Otherwise, degradation of
the performance of this device could result.
• To avoid the risk of electric shock, this equipment must only be
connected to a supply mains with protective earth.
NOTE!
• This device 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
the 'Purpose of use' chapter.
1.6 Light toxicity
WARNING!
• The light from this device may be dangerous. The risk of eye
damage increases with the exposure time. An exposure time with
this device at maximum intensity of longer than 131 seconds
exceeds the guideline value for a risk.
• As extended, intensive illumination can damage the retina, the use
of the device in the examination of the eye should not be prolonged
unnecessarily. The illumination of this slit lamp emits a radiation in
the range between 400 and 750 nm. Detailed information on the
radiation can be provided on request.
• The retinal dose for a photochemical risk is composed of the product
of the radiance and the exposure time. If the radiance 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
intensity 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
flashbulb in advance.
1.7 Disinfection
NOTE!
The device can, but does not need to be disinfected. For more
information, please refer to the 'Maintenance' chapter.
