We are constantly endeavouring to improve our instruments and
to adapt them to the requirements of modern research techniques
and testing methods. This involves modification
to the mechanical structure and optical design of our instruments.
Therefore, all descriptions and illustrations in this instruction
manual, including all specifications are subject to change
without notice.

Introduction
Thank you for your purchase of a Motic microscope. Motic microscopes are
precision instruments, subjected to stringent quality control in order to reach
you in perfect condition. Their design combines easy management and
optimum functioning with minimum maintenance.
The information contained in this manual is likely to go beyond what the
average user needs to know to use the microscope, however, it is provided to
answer any queries that may arise.
Your new microscope combines high performance features, with an excellent
degree of optical resolution and clarity of image. Some models incorporate a
mechanical stage which provides a travel range of 75mm x 35mm in X and Y
directions with a graduation of up to 0.1 mm, thus permitting the perfect
positioning of the specimen. Also included are objectives located in a
nosepiece allowing movement in both directions; a precision coarse and fine
focusing system; accurate condensers with a numerical aperture of 0.65 N.A.
or 1.25 N.A. and LED illumination with variable intensity control.
These instructions should be read carefully before operating the microscope.
They will permit you to use your new microscope to its fullest capabilities.
Terminology used to describe components and controls can be found in the
diagram on page 2.
These instructions are based on the assembly and use of the BA80 model
with additional notes applying specifically to other models in the series.

Unpacking
All components of the microscope have been carefully packed to ensure they
reach you in perfect condition. We recommend that you do not discard any
packing containers in case you need to return the microscope, store it for long
periods of time; or should it become necessary to transport it to a technical
service for any repair, or maintenance procedure.
The box should contain the following components, depending on the model:
A microscope assembled with a monocular head, an eyepiece, a fixed
stage, 0.65 N.A. condenser or 1.25 N.A. Abbe condenser and three
objectives or four objectives.
Additional components are: a blue filter, a dust cover, and two hexagonal
keys measuring 2mm and 0.85mm.
Remove, and handle the microscope and all its components with
extreme care.
Avoid touching the lenses of the optical elements and keep clear of
contact with dust, water or other contaminating agents, as they could
stain, or damage the lens surface and affect the quality of the image.
A. Place the microscope in an upright position on a flat, stable and
clean surface.
B. Remove the rest of the components from the box.

Description of Components
1. Head — Monocular head rotating 360º to avoid the necessity of moving the
microscope, should another user wish to use it.
2. Eyepiece — The group of lenses closest to the eye, magnifying the image
formed by the objectives. In the monocular models, the eyepiece contains a
pointer to single out any particular element of the sample to another user.
3. Revolving nosepiece — The revolving action permits the user to change
the degree of magnification, the correct positioning of the objectives is
marked by a “click” in the optical path.
4. Objectives — The group of lenses closest to the sample, or microscopic
specimen forming the primary magnified image.
5. Stage — Platform of the microscope where the specimen is placed. Models
with plain stage where specimen slide is held in place by specimen holder
clips. In other models, a mechanical stage replaces the clips, and permits
precise, mechanical manipulation of the specimen slide.
6. Condenser — Optimises illumination for enhanced resolution and
image contrast.
7. Focusing Knobs — Situated on both sides of the arm of the microscope,
the larger, or coarse focusing knob initially brings the specimen into focus,
and the smaller, fine focusing knob permits a precise adjustment of
the image.
8. Illumination — LED illumination with intensity control knob.

Setting up the instrument
Avoid placing the instrument in locations exposed to direct sunlight,
dust, vibration, high temperature and high humidity
1 Operating Enviroment
Indoor use.
Altitude : Max 2000 meters
Ambient temperature : 15°C to 35°C
Maximum relative humidity : 75% for temperature up to 31ºC decreasing
linearly to 50% relative humidity at 40ºC

Installation / Overvoltage category : 2 (in according with IEC60664)
Air Pressure of 75kPa to 106kPa
No hoar frost, dew, percolating water, rain
2 Verifying Input voltage
The automatic voltage selection works with a broad range of settings.
However, always use a power cord that is rated for the voltage used in your
area and that has been approved to meet local safety standards.
Using the wrong power cord could cause fire or equipment damage.
In case of using the extension cord, use only a power supply cord with a
protective earth (PE) wire.
In order to prevent electric shock, always turn the power switch on the
power supply off before connecting the power cord.
Input : 110V~ 60Hz
Lamp: 3.1V 60mW LED
Fuse : 125V T0.5A
OR
Input : 220V~ 50Hz

Warning: Before connecting the microscope to an electrical source, always
check that the voltage coincides with that of the microscope.
Assembly
All the steps described for the assembly of the microscope must be
undertaken with extreme care, and without forcing the placement of the
distinct parts and elements of the microscope.
A. Specimen holder mechanism for models with built in mechanical stage:
Rotate the coarse focusing knob to move the stage to its lowest position.
Remove the two knurled screws of the specimen holder mechanism. Place
the mechanism on the stage with the moveable clip lever facing outwards,
and making sure that the holes of the mechanism, and the knurled locking
screws coincide, screw down firmly.

Operation
A. Starting Up
1. Before using the microscope, adjust the light intensity control to minimum
position. This should be repeated every time the microscope is switched
on or off to prolong the use of the bulb.
2. Press switch to position ON. (Fig. 1)
Fig. 1
3. Rotate light intensity dial until the image is illuminated.
4. Light intensity should be adjusted in accordance with the objective
used, or the type of specimen examined.
* Using LED illuminating microscope (Rechargeable batteries)
