1. Intended use of the equipment
This microscope is intended mainly for use in microscopic observation of rock and mineral or polymer
materials or substance of living body, using polarized light illumination.
It is designed for the main purposes of analysis of the optical character, in laboratories or hospitals, of
such samples within the fields of mineralogy, high polymer chemistry, medicine.
2. Do not disassemble.
Disassembly may cause malfunction and/or electrical shock, and will lead to the forfeiture of all claims
against warranty. Do not disassemble any part other than those described in this manual. If you
experience any problem with the microscope, notify your nearest Nikon representative.
3. Check the input voltage.
The input voltage is indicated in two places at the rear of the microscope: on the nameplate and above
the AC inlet. Confirm that these input voltage indications correspond to the voltage provided in your
region. If not, follow one of the instructions below. The use of microscopes with the different input
voltage indications will cause overcurrent and overheating, which may result in fire or severe damage
to the microscope.
• If the voltage indication on the nameplate differs:
Î Do not plug in the microscope. Contact your nearest
Nikon representative.
• If the voltage indication above the AC inlet differs:
Î Refer to p. 35 and change the input voltage
setting before turning on the power switch.
• For the microscope with the nameplate showing
[100/110/120 V ~]:
The voltage can be set to: AC 100 V, 110 V or 120 V.
• For the microscope with the nameplate showing
[220/230/240 V ~]:
The voltage can be set to: AC 220 V, 230 V or 240 V.
4. Use the specified lamp, fuse, and power cord.
Use the specified lamp and fuse. Use the power cord provided. Using an incorrect lamp, fuse, or power
cord may damage the instrument or cause a fire. (Also see p. 50 on power cord.)
If using an extension cord, only use a cord that includes a protective earth (PE) wire.
