3. Assembling The Microscope
3.1. 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.
•

3.2. Lamp and Lamp House Cover
(Replacing The Lamp)
The lamp and the lamphouse become very hot during and after
a period of operation.
Risk of burn – Do not touch the lamp during or immediately
after period of operation.
Make sure the lamp has cooled sufficiently before attempting
to replace the lamp.
a. Halogen
•
In order to prevent electric shock always turn the power
switch off and unplug the power cord before installing or re-
placing the lamp.
•
Place microscope on its back and pull back the lamp house
cover plate.
•
Firmly insert the lamp into the socket pinholes until it reach-
es the limit. Be careful not to tilt the lamp when mounting.
•
When installing the lamp, do not touch the glass surface of
the lamp with bare fingers. Doing so will cause fingerprints,
grease, etc., to burn onto the lamp surface, reducing the illu-
mination provided by the lamp. If the surface is contaminated,
