Reset the output setting of the embedded monitor and
external monitor. (Turn on the power of the DS-L3
again, turn off it while the Power indicator is blinking,
and then turn on the power again.)
Cables are connected incorrectly.
Use the commercial DVI cable (digital/analog) to
connect the DVI-I connector of the DS-L3 to the video
input connector of the external monitor.

View of Images
Symptom
Possible cause
Action
The optical device is out of focus.
Bring the optical device into focus by operating the
focus drive or focusing ring.
The aperture diaphragm is closed too
much when using the microscope.
Adjust the aperture diaphragm to 70 to 80 percent of
the numerical aperture of the objective, or 70 to 80
percent of the pupil of the objective.
The magnifying power of the optical
device is too much.
As a guide, use 500 to 1000 times the numerical
aperture of the objective for the magnifying power.
The electronic zoom is being used for
observation.
Use of the electronic zoom may cause an image to
blur depending on the magnification.
Revise the setting of [SHARPNESS] in the [CAMERA
MENU : IMAGE] window.
The sharpness setting is low.
For the external monitor, adjust the sharpness setting
for the monitor.
The system is used in a place subject
to frequent vibration.
Use the system in a stabile, vibration-free place.
The image blurs.
The exposure time is too long.
If setting the exposure time long for a subject in
motion, the subject is blurred. Change the exposure
mode to shutter priority or manual, and set the
exposure time to a fast value.
When there is difficulty in focusing a dark subject, it is
recommended to use focus priority.
