Condition #4
After CaP db is displayed these indicators may appear (After Capture
mode). It confirms the digital back is storing an image and that there
are certain number of frames left in the memory of the digital back. This
indicator shows the remaining frames left by displaying Stor 88 (where
88 is a number between 99 and 1). This will be displayed when the
frames-to-go is less that 100. This display will blink for 3 seconds and
can be cancelled by pressing any button. Note: Some digital backs will
only display Stor db in this instance. If the db-E and Stor conditions are
both true, the db-E will be displayed for 3 seconds and then Stor will
be displayed for 3 seconds.

mode). This is warning that the storage capacity of the digital back has
been reached. If the shutter release button is pressed at this time the -
no- db indication will blink for 3 seconds.
Condition #5
When the battery of the digital back has been exhausted this indication
will appear. If the shutter release is pressed the -no- db indication (see
