Ⅰ. Safety Notes

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. 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 before replacing the halogen/LED lamp or the fuse,

then cut off the power, and do the operation after the lamp bulb and the lamp house completely cool

down. (Specified: Halogen Lamp6V/20W)

7. 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.

8. Use the factory supplied power cord, please.

II. 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 possibly as you can.

3. The nosepiece and coarse/fine focus unit have a compact and precise frame; please don’t disassemble

them as possibly as you can.

4. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the optical

elements especially.

5. 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 aether. (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.)

6. 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.

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

moisture.

8. Do not disassemble any parts of the microscope, which will affect the function or decline the

performance of the microscope.

9. 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.

The following figure shows the installation sequence of the components. The number in the figure shows the

assembly steps.

Before installing, be sure every components is clean, do not score any parts or glass surface.

Keep well with hexagon wrench provided. When replacing the components, you will need it again.

2.2.1 Installing Binocular viewing head

(Fig.1, 2)

Insert the digital viewing head into the

microscope head, turn into the right position,

then screw down the bolt ①to fix it.

2.2.2 Installing the eyepieces (Fig.3,

Fig.4)

Insert the eyepieces into the eyepiece tube

until they are against each other as shown in

Fig.4.

NOTE:

Operation Conditions:

1．Temperature: 0℃～40℃, Maximum

Relative Humidity: 85%.

2．High Temperature: High Temperature

and humidity will result in a mildewing,

dew and even ruinous instrument.

3．Avoid placing the instrument in a dusty

environment. When ending your

microscope operation, please cover it with

the dust cap.

4．Pleas lay the microscope in a plan and

stable position.

2.2.3 Installing objectives (Fig.5& 6)

1. Adjusting the coarse focus knob until the

support device of the mechanical stage

reaches its low limit position.

2. Screw the lowest magnification objective into

the nosepiece from the left or the right side,

then 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”,

which means the objective is in the

required position--the light path center.

2.2.4 Installing the color filters (Fig.7)

1. Turn the condenser bracket①out at the

direction of arrow in Fig.7

2．Put the required filters②into the holder on the

bracket, and then turn the bracket back to the

right position.

★Baby blue and green filters are available in

standard outfit.

2.2.5 Connecting the power cord (Fig.8, 9,

10)

★The cable and cords are vulnerable when bent

or twisted, never subject the power cord to

excessive force.

1. Turn the main switch①to “O” (off) state before

connecting the power cord.

2. Insert the power plugs ②into the power jack③of

the microscope; make sure the connection is well.

3. Plug the power cord ④into the power supply

receptacle safely. Make sure the connection is well.

★Do use the supplied power cord all the time. If lost

or damaged, please select the same standard cord.

2.2.6 Replacing the Fuse (Fig.8, 9, 10)

Do remember to set the main switch①to the state of

“O” (OFF) and unplug the power cord ②before

replacing the fuse. Rotate the fuse kits⑤out of the

holder, replace with a new fuse, then rotate it back to the

holder again.

★The rating of the new fuse should be the same as

the old one.

2.2.7 Installing and replacing the lamp

(Fig.11, 12)

Please use the specified halogen Lamp

(6V20W) or LED lamp. Replace the lamp as

follows if necessary.

1. Please set the main switch to “O” (off) state

before replacing, and make sure the bulb, the

lamp room and periphery are all cool enough to

carry no burn. Then, you can do your

replacing.

2. Loose the bolt ①and open the window②on

the bottom of the microscope base with

“一”type screwdriver.

3. Pull out the old bulb③, hold the new bulb

after you wrap it with gauze or other protection

materials and insert its pin as deeply as

possible into the jack in the lamp holder.

4. Close the window and tighten the bolt ①.

Please insert the bulb gently, or it will be

damaged by excessive extrusion.

Do not touch the halogen bulb with bare

hands. It will shorten the service life or

cause it to burst. If you leave

fingerprints on the surface carelessly,

clean it with a piece of dry soft cloth.
