Change the number of expo-
sures or repeat limits to a suit-
able quantity The number of exposures
is not approriate in Incre-
ment or Repetition mode Please input a valid repeat limit
count.
Click the OK button if you wish
to take an exposure without
correction CCD calibration will not be
accurate since the temper-
ature is not stable (when
exposing an EtBr sample
before the CCD has
reached its target cooling
temperature) CCD Cooling is not stable.
Dark frame correction will not be ac-
curate.
Do you want to continue?
Check that the intended light
source(s) are correctly in place
and that correct method is
chosen The incorrect light source
is installed Can not start the exposure because
the light source does not match the
method. Please exchange the light
source or select another method.
Create a correction file that
satisfies exposure conditions
using the Flat Frame Calibra-
tion function in the Option
menu There is no Flat Frame file
that satisfies the exposure
conditions. Cannot start the exposure. Flat frame
calibration has not been performed.
Please run flat frame calibration for
the selected settings.
Cannot start the exposure. Flat frame
calibration has not been performed
for digitization epi-illumination.
Please run flat frame calibration for
digitization epi-illumination.
Flat frame calibration data was not
found.
Click the OK button to start ex-
posure. CCD calibration for the
exposure conditions is initiated. CCD calibration is not
ready for exposure Cannot start the exposure. CCD cali-
bration has not been performed.
Please run CCD calibration for the
selected exposure time. Calibrate
now and continue?
Create a correction file that
satisfies exposure conditions
using the CCD Calibration
function in the Option menu The CCD is not calibrated Cannot start the exposure. CCD cali-
bration has not been performed.
Please run CCD calibration for the
selected exposure time.
Create a correction file using
the CCD Calibration function
in the Option menu. Perform
calibration for both over 2
hours and from 1/100 sec to 2
hours. No CCD calibration file ex-
ists. Cannot start the exposure. Automatic
exposure requires CCD calibration.
Please run CCD calibration for the
exposure time range from 1/100 sec
to 2 hours.
