What to do if...?
13 What to do if...?
If electrically operated functions do not work properly, always check these points first:
• Is the power switch switched on?
• Are the power cables attached correctly?
• Are all connecting cables attached correctly?
• Are all video cables attached correctly?
For malfunctions regarding the ARveo 8, refer to the corresponding user manual.
13.1 Calibration
Observation
The GLOW800 fluorescence image is incorrectly
aligned to the White Light image
13.2 Control Unit
Observation
Incorrect information is shown for interpretation
to the user
The system is not booting up
An error message "connection to camera lost"
appears
The system is frozen/no reaction
13.3 Limitation
Observation
In high magnification the GLOW800 fluorescence
is out of focus, although the White Light image is
sharp
Some parts of the fluorescence image are sharp
(region of interest), others are out of focus
30
Cause
The setting to fit both images are incorrect
Cause
Device algorithm calibration failure
Improper pre-operational check
Electronic failure
Camera signal lost
Software initialization failure
Cause
In high magnification the NIR focus can differ
from the WL focus
The out of focus fluorescence does not cover the
object, the fluorescence floats above the object
GLOW800 / Ref. 10 748 652 / Version 01
Remedy
The settings have to be adapted to fit both
X
images.

Remedy
Reduce the magnification until you receive a
X
sharp GLOW800 image
Even when the ROI is in focus, other fluorescent
areas might be not and can produce disturbing,
floating fluorescence. If not all fluorescent areas
can be in focus, there is no way to avoid this
effect.
