3.5.3 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. 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 Changing objectives
•
Turn the focusing drive to move the mechanical
stage fully down.
•
Turn the nosepiece (Fig. 29/ 3 ) to move the
objective to be changed (Fig. 29/ 1 ) into a lateral
position.
•
Unscrew the objective using the rubber strip
included in the delivery and remove it
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 corresponding mount of the
nosepiece.
