User Notices

I. Safety note

i. When unpacking, please take care not to drop fragile items, such as lenses.

ii. Keep the instrument out of direct sunlight; avoid high temperatures or humidity, dusty environments. Make sure the work

surface is stable and away from sources of vibration.

iii. Take care when moving the instrument, using two hands to grip with the sides of the microscope body.
iv. Caution! The lamp house and nearby parts will be very hot during operation. Ensure sufficient space to allow cooling.

v. Before replacing the halogen lamp, or fuse, make sure the main switch is in the “O” (off) position, and turn off the mains

power. Allow the lamp bulb and lamp house completely cool before removal.

vi. Use the factory supplied power cord.

II. Maintenance

i. Do not disassemble any parts of the microscope, as it will affect function, or reduce the performance.

ii. Keep the instrument clean and cover with a dust cover when not in use. Remove dust with a lint-free cloth. Take care to

avoid contaminating the optical elements.

iii. Marks on the prism, such as finger marks or oil should be removed by gently wiped with a piece of lint-free cloth immersed

in pure alcohol or xylene (NOTE: alcohol and xylene are highly flammable. Keep away from heat sources and use them in a

well-ventilated room).

iv. Do not use organic solvent to wipe the non-optical elements.

v. Place the instrument in a cool, dry environment. After using the microscope, cover with a dust cover.

Wait for the lamp house to cool completely before covering.

2-2 Installation Steps

2-2-1 Installing the mechanical stage support

Before installing the device, be sure to adjust the coarse focus
control ①. Move the guide board ② down to the lowest

position, so you can install the mechanical stage support device

easily.

Hold on to the mechanical stage support device (Fig.2). Place it

from the top of the guide board (Fig.1), until the stage reaches the

lowest position. Use the Allen key provided to secure the stage
③.

 The mechanical stage ⑤ has been adjusted before

leaving factory. Do not disassemble.

Assembled parts should look like Fig.3.

2-2-2 Installing the reflected light brightfield /

darkfield illuminator

Install the reflected light illuminator (Fig.4) on the head of the
microscope body (Fig.5) and then secure the bolt ⑥.

2-2-3 Installing the trinocular head

Insert the video port (Fig.6) into the illuminator (Fig. 4), and then

secure the bolt.

2-2-4 Installing the objective

1. Adjust the coarse focus knob until the support device of the

mechanical stage reaches its lower limit position.

2. Place the lowest magnification objective onto the nosepiece

from the left or the right side and then push the nosepiece

clockwise. Then place other objectives in the sequence of low

to high magnification (Fig.7).

 When replacing the objective, slowly turn the

nosepiece until you hear a “click”. The objective will

now be in the required position-(the centre of the

light path).
