drive is too low.
Increase the torque of the coarse
focusing drive to make motion stiffer.

Fluorescence light source or circuit
board is defective.
Contact service person for further
checking. If necessary, change LED
source or PCB.
Replacement requires special tools and
can thus not be carried out by the
customer.
Greenish background when
working in fluorescent
illumination mode.
The yellow filter is not inserted.
The transmitted LED phosphor
