Safety Note

Note

1. Open the box carefully to avoid the accessories, like lens, dropping to ground or 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 flat, horizontal and firm enough.

3. When moving the microscope, carefully carry it with the handle and the base.

4. When 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. For safety, be sure the main switch is in “ O ” (off) state and cut off the power supply before

replacing the bulb or the fuse. If you replace the bulb during use or right after use, allow the lamp

bulb and the lamp house to cool completely before touching.

7. Check the input voltage: be sure the input voltage which is signed in the back of the microscope is

consistent with the power supply voltage, or it will bring a serious damage to the instrument.

8. Always use the power cord provided by Novel.

and Care

Care

1. All the lenses have been adjusted properly; do not dismount them by yourself please.

2. The nosepiece and coarse and fine focusing parts are so delicate that it is forbidden to

disassemble them carelessly by yourself.

3. Keep the instrument clean, and do not pollute the optical element when wiping away the dust on

the instrument.

4. The contaminations on the prism, like fingerprints and oil smudges, could be gently wiped with

a piece of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or ether.

5. Do not attempt to use organic solvents to clean the microscope components other than the glass

components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted neutral

detergent.

6. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe away

the splash.

7. Do not disassemble any parts of the microscope, as this will affect the function or reduce the

performance of the microscope.

8. Place the instrument in a cool, dry position. When not using the microscope, keep it covered

with a dust cover. Make sure the lamp socket is cool before covering the microscope.
