To activate the transmitted light illuminator, put the
main switch ①, located on the left side of the stand,
to the position "1". (Fig. 22)
• For B-1000POL-I model only. There is a three-
position switch on the left side of the stand:
position "I" turns on the transmitted light, position
"II" turns on the reflected light and position "O"
turns off the microscope.

Control keyboard

B-1000 illumination can be managed through the
keyboard placed on the left of the stand. (Fig. 23)
• ON-OFF (②): press this key (after switching the
main switch on "1") to turn ON or OFF the micro-
scope LED.
• BOOST (③): press this button in order to in-
crease the brightness (useful for high-magnifi-
cation objectives or very opaque specimens).
Do not enable boost mode while observing
with low magnification objectives (4x, 10x)
with fully open diaphragm: the high bright-
ness may hurt user's eyes.
• AUTO OFF (④): if you want the illuminator to
switch off automatically, press this button until 15,
30 or 60 minutes delay is set. After this period of
time, the light will turn off. You have to press the
ON-OFF button to turn it on again.
