crease the brightness (useful for high-magnifi-
cation objectives or very opaque specimens).
Do not enable boost mode while observing

with fully open diaphragm: the high bright-
ness may hurt user's eyes.

30 or 60 minutes delay is set. After this period of
time, the light will turn off. You have to press the
