Ⅰ. Safety 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. Make sure the instrument is earthed, toavoid lighting strike.
5. 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.
(Designated bulb：1W S-LED or 6V20W Halogen Lamp)
6. 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.
7. Always use the power cord provided by Novel.
8. The electrical equipment of the microscope should be discard as electronic waste.
Ⅱ. Maintenance and 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. (Note
that the alcohol and ether are highly flammable, do keep them away from the fire or potential
sources of electrical sparks, and use them in a drafty room as possible as you can.)
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, softcloth 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.

revolve the nosepiece clockwise and mount other
objectives by the sequence of low to high
magnification
◇ Installing objective this way will make the change of
magnification to be easier during using.
★ Clean the objective regularly, for lens is
susceptible to dust.
★ When operating, use 10 × magnification
objective to search and focus specimen
firstly, then replace with higher
magnification objective if necessary.
★ When replacing the objective, slowly turn
the nosepiece until you hear “clicked”,
that means the objective is in place.
2.2.4 Mounting the filters（Fig.7）

2. Hold the bulb②after you wrap it with gauze or
other protection materials, and then insert its
pindeeply intothe jack in the lamp holder.
3. Duringmicroscope using or soon after it is turned
off, the bulb, the lamp house and nearby parts will
be very hot and will cause serious burns. Please
turn the main switch to“O” (off) and disconnect the
