Start-Up and Operation
3.5.3
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. 28/3) of the
illumination module (Fig. 28/1 or 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. 28/1 or 2) out
of the stand.
• If the stand is equipped with a 6V 30W halogen
lamp (Fig. 28/2), remove the halogen lamp
(Fig. 28/4) 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. 28/1).
• Push the illumination module (Fig. 28/1 or 2)
back into the stand and fasten it by means of
the two screws (Fig. 28/3). In doing so, slightly
press the screws against the spring and turn
them by 90°: Turn left screw counterclockwise
and right screw clockwise.
3.5.4
• Turn the focusing drive to move the mechanical
stage fully down.
• Turn the nosepiece
objective to be changed (Fig. 29/1) into a lateral
position.
• Unscrew the objective using the rubber strip
included
downward.
• Screw the desired objective (Fig. 29/2) hand-
tight 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
nosepiece.
