SCHOTT KL 2500 LED User Manual page 15

• When illuminating heat-sensitive or flammable light-absorbing objects, pay
particular attention to selecting the light guide spacing and intensity so that
no thermal damage occurs to the object. Since light-absorbing materials have
the physical property of converting incident light into heat, damage can occur
to heat-sensitive or flammable light-absorbing materials.
• All light guide outputs must always be at a safe distance – at least 10 cm – from
heat-sensitive or flammable light-absorbing materials when the light source is
switched on (avoid possible fire hazard).
• Reduce the brightness and duration of illumination of biological tissue to avoid
unnecessary exposure of biological tissue to visible light illumination.
• Keep all ventilation openings free. In case of insufficient cooling, an integrated
thermal switch will regulate the light intensity of the light source.
• Safe disconnection from the power supply is only achieved by pulling out
the plug.
• Do not open or disassemble the device. Refrain from making technical modifi-
cations to the device.
• Allow the filter slider and insert filter to cool down before removing the insert
filter. The filter slider must always be in a detent position when operating the
light source (see "Filter slide").
• Allow the light guide to cool down before replacing it. We recommend that
you switch off the light source for about five minutes before replacing the light
guide. uide outlet with your hand or other parts of your body (risk of burns)!
