Replacing the 6V 30W halogen
lamp or the LED illumination
Unplug the plug-in power unit from
the power outlet and allow for a
sufficient cool-down time of the
6V 30W halogen lamp before you
replace it.
• Loosen both fastening screws (Fig. 13/3) of the
illumination module (Fig. 13/1 o 2). In doing so,
slightly press the screws against the spring and
turn them by 90°: Turn left screw clockwise and
right screw counterclockwise.
• Pull the illumination module (Fig. 13/1 or 2) out
of the stand.
• If the stand is equipped with a 6V 30W halogen
lamp (Fig. 13/2), remove the halogen lamp
(Fig. 13/4) from the lamp carrier and insert the
new halogen lamp. Do not touch the new lamp
with naked fingers as this will reduce lamp life.
• If the stand is equipped with an LED source,
replace the complete illumination module
including the LED (Fig. 13/1).
• Push the illumination module (Fig. 13/1 or 2)
back into the stand and lock it by means of the
two screws (Fig. 13/3). In doing so, slightly press
the screws against the spring and turn them by
90°: Turn left screw counterclockwise and right
screw clockwise.

Changing objectives
• Turn the focusing drive to move the mechanical
stage fully down.
• Turn the nosepiece (Fig. 14/3) to move the
objective to be changed (Fig. 14/1) into a lateral
position.
• Unscrew
the
objective
downward.
• Screw the desired objective (Fig. 14/2) into the
nosepiece as far as it will go.
• If you intend to insert the objective in a lens
mount not used so far, remove the dust cover
from
the
corresponding
nosepiece.
