There is less light
apparent in the
right eyepiece
On microscopes fitted with video
systems it is normal for slightly
less light to be apparent since a
small proportion is diverted to the
video camera
The foot control is
not working
Check if the foot control indicator
lights up when the zoom or focus
pedals are depressed. If the light
comes on when the pedals are
depressed the foot control is
working and the problem is
elsewhere
If the light does not come on,
check that the foot control is
properly connected to the power
supply.
Check to see if the problem is
specific to up or down movement,
or a particular part of the focus
range
Open the focus housing by
removing the 4 screws. Check for
worn focus gears or gear
misalignment.
If you are unable to fix the
problem or require further advice,
contact your distributor, local
service agent or Scan Optics.
