1 Before use
1.1 General information
The packaging must be opened carefully to prevent the accessories inside from falling
to the floor and breaking.
In general, a microscope should always be handled with great care, as it is a sensitive
precision instrument. Avoiding abrupt movements during operation or transport is
therefore particularly important, especially in order not to endanger the optical
components.
Likewise, you should avoid dirt or fingerprints on the lens surfaces, as this will reduce
image clarity in most cases.
If the performance of the microscope is to be maintained, it must never be
disassembled. Components such as objective lenses and other optical elements
should therefore be left as they are found at the start of operation. Also the electrical
part at the back and at the bottom of the instrument must not be tampered with without
further ado, because here there is the additional danger of triggering an electric shock.
1.2 Notes on the electrical system
Before connecting to a power supply, be sure to use the correct input voltage. The
power cord selection guide is located on the back of the unit, just above the power
jack. Failure to follow these instructions may result in fire or other damage to the unit.
Also, the main power switch should be turned off before connecting the power cord.
This will prevent an electric shock from occurring.
If you use an extension cord, the power cord you use must be grounded.
If the original fuse blows, replace it only with a suitable fuse. Suitable replacement
fuses are included in the scope of delivery.
All handling of the equipment that involves contact with the electrical system, such as
changing lamps or fuses, may only be carried out when the power supply is
disconnected.
