1-3 Getting Ready
1. The camera head uses precision components. Handle it with care and avoid subjecting it to a sudden or severe impact.
2. The image displayed on the monitor may be affected when it is used near equipment generating strong electromagnetic
waves. To avoid interference during operation, keep the system far from any source of electromagnetic waves.
3. Do not use the camera in areas where it may be subjected to direct sunlight, high temperature and humidity, dust or
vibrations. (For the operating environment conditions, see “SPECIFICATIONS” on page 83.)
1-4 Maintenance and Storage
1. To clean the lenses and other glass components, simply blow dirt away using a commercially available blower and wipe
gently using a piece of cleaning paper (or clean gauze).
If a lens is stained with fingerprints or oil smudges, wipe it with gauze slightly moistened with commercially available
absolute alcohol.
Since the absolute alcohol is highly flammable, it must be handled carefully. To prevent fire ignition, be sure
to keep it away from open flames or potential sources of electric sparks -- for example, electrical equipment
that is being switched on or off.
Also remember to always use these chemicals only in a well-ventilated room.
2. Parts other than the glass components should be cleaned by wiping with a clean cloth. Do not use organic solvents to
remove major stains. Use a soft cloth slightly moistened with a neutral detergent solution.
3. Do not disassemble any part of the camera as this could result in malfunction or reduced performance.
4. When the system is not used, store it with the dust cover. Before storage, ensure that the main switches of the DP21’s
control box and the microscope are set to OFF and that the lamp housing is cool enough.
5. When smoking the room for cleaning, etc., move the DP21 to a place not exposed to smoke.
6. Care is required against condensation as this may sometimes cause malfunction. Condensation is the phenomenon in
which the vapor in the air is condensed into water drops, which attach to the surface of a metallic plate, etc. It often occurs
when the ambient temperature changes suddenly, for example when a camera is brought from cold outdoors into warm
indoors.
