2.2.7 Installing and replacing the lamp
(Fig.11,12,13)
There are two types of illuminator available
for this microscope, one type is halogen lamp
6V20W, the other is 3W LED. During use or
just after using, the lamp house and nearby parts
will be very hot. 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.
1. Loose the bolt①and open the window②on
the bottom of the microscope base with
“一”type screwdriver.
2. 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 bolt①.
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.
When replacing LED :
1. Generally, the LED has long service life and
is not easy to damage, if unfortunately it
damaged, purchase a new one from the
supplier.
2. Remove the base plate⑥from the bottom
side of the microscope base with screw
driver ,loose the bolt⑤to take the old LED
off, replace with a new one .
3. Put the new LED unit back onto the bracket
with the bolt⑤and the base plate⑥onto the
bottom side of the microscope.
When you take down the base plate,
please do it gently and slowly, to avoid
damaging internal electrical wires.
