The control unit is operated in a similar way to
the key-mode operation of the Leica DM IRB
microscope.
Significance of individual keys:
LAMP
Brightness can be adjusted with the arrow keys:
Up arrow
→
brighter, down arrow
→
darker.
The ON/OFF key is used to switch the lamp off
and on. When it is switched on again, the
brightness that was set before it was switched
off is reset.
MAG
The arrow keys are pressed to change the
magnification. The objective nosepiece rotates
to the next higher magnification within the same
operating mode (IMM/DRY) when the upwards
arrow key is pressed once. Similarly, the next
lower magnification is switched to when the
downwards arrow is pressed. If the same key is
pressed more than once in quick succession,
the nosepiece is rotated by the corresponding
number of valid positions.
This is also the reason why the nosepiece
rotation is slightly delayed after the keys are
pressed.
The LAST key is used to switch to the objective
that was used last.
FLUOR
The arrow keys are used to switch from one
filter cube to the next.
Pressing the keys several times causes the
corresponding position to be jumped to.
The LAST key positions the filter cube that was
set before the last keystroke.
The SHUT key is used to close the dark flap.
