The switch on the microscope only switches into standby mode.
Do not replace detachable mains cables by inadequately designed mains cables. Only the
specified power supply lines may be used.
The microscope and the controller K LED are equipped with a desktop power unit each
allowing line voltages in the range from 100 V to 240 V ±10 %, 50 – 60 Hz, without the need
for changing the voltage setting on the device.
The desktop power unit meets the requirements of protection class II (with protective
insulation). If its casing is damaged, put the power unit out of operation. The microscope may
only be operated with the desktop power unit supplied with the instrument.
Changing the lamps on the cold light source is only admissible in accordance with the
manufacturer's operating manual. If the appropriate instructions are not complied with, there is
a risk of burns and explosion when changing the lamp.

when not in use. Before covering the device, always make sure that it is definitely switched OFF.
Considerable temperature fluctuations, direct exposure to sunlight and vibrations should be
avoided.
Blocking or covering ventilation louvers may result in heat accumulation which may damage the

insert or allow any objects to fall into them. All electrical components and parts must be located
at a distance of min. 15 cm from flammable objects and walls.
