1. Safety note
1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being damaged.
2. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy
shaking environment. Make sure the stage is smooth, horizontal and firm enough.
3. When moving the instrument, please use two hands to grip with the two sides of the microscope
body.
4. If the bacterium solution or the water splash to the stage, objective or viewing tube, pull out the
power cord at once, and wipe up the microscope. Otherwise, the instrument will be damaged.
5. When running, the lamp house and nearby parts will be very hot. Please ensure there is enough
cooling room for them.
6. Make sure the instrument is earthed, to avoid lighting strike.
7. For safety, be sure the main switch is in “O”(off) state before replace the halogen lamp or the fuse,
then cut off the power, and do the operation after the lamp bulb and the lamp house completely
cool.
8. Check the input voltage: be sure the input voltage which signed in the back of the microscope is
consistent with the power supply voltage, or it will bring a serious damage to the instrument.
9. Use the factory supplied power cord, please.
2. Maintenance
1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them yourself.
2. The nosepiece and coarse/fine focus unit have a compact and precise frame, please don’t
disassemble them as possible as you can.
3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the
optical elements especially.
4. The contaminations on the prism, as finger mark and oil, could be gently wiped with a piece of soft
cloth or tissue paper, gauze which has been immersed in pure alcohol or xylene. (note that the
alcohol and the xylene are all burned easily, do not let them near the fire, and use them in a
drafty room as possible as you can.)
5. Don’t use organic solvent to wipe the non-optical elements, when you need to clean, use the soft
detergent, please.
6. When using, if the microscope is splash by liquid, cut off the power at once, and wipe up the
