4. MAINTENANCE AND TROUBLESHOOTING
4.1 Maintenance
The biological microscope is limited to the following maintenance only:
● Turn off the power switch after use, and put on the dustproof cover after the
microscope has cooled down.
● Do not operate the microscope in a room with humidity higher than 75%.
● Remove dust or ordinary dirt on optical lens surfaces with a brush, rubber
suction bulb and a moistened lens tissue.
● Use only optical lens tissues and optical lens cleaner (see below). Never
clean a lens with a dry optical lens tissue. Be sure to remove any dust
before using lens tissue and cleaner.
● To remove stubborn oily or lipoid dirt (such as immersion oil or fingerprints),
dip the lens tissue into a 3 to 7 ethanol-ether mixture or a commercially
available optical lens cleaning solution and then use it to wipe off the dirt.
● When cleaning an optical lens surface, wipe gently in a circle from the
center to the edge.
