12. Cautions when Carrying the Microscope (cont'd)
• Never attempt to move the microscope by
holding the focus knob, eyepiece tube, dark
box, lamphouse, stage or the like. Such an
attempt may cause any of these parts to be
pulled off and damage the instrument.
• When moving the microscope on the desk, do
not drag it. Lift it and put it down gently
where it is to be placed again.
13. Serial Numbers of the Microscope and
Key Component
The serial numbers of the microscope, its
eyepiece tube and of the control box should be
identical. If this microscope is used together
with an eyepiece tube and a control box each
with a serial number different from that of the
microscope, it will not exhibit its performance
properly.
