1. C arefully 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, horizon tal and firm enough.

3. I f 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.

4. W hen running, the lamp house and nearby parts will be very hot. Please ensure there is enough

cooling room for them.

5. Make sure the instrument is earthed , to avoid lighting strike.

6. F or 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.

7. C heck 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.

Use the 10 × objective focus, to avoid the

objective touch with the specimen, you

should raise the mechanical stage at first, let

the specimen close to the objective, then

slowly separating them to focus.

The operator can converse turn the coarse

focus knob to get the specimen down ,and

search images in the 10 × ocular

focus . A t this moment, you can replace other

magnification objectives safely, and focus

without the risk of destroy ing the specimen.

2、When using the video set
