(Note ) Decibel value in “Selection of gain preset” is a relative value based on Preset 1.
(Note) The shutter speed can be changed only when the shutter switch is currently set at any other positions than “0”.
When the shutter switch is positioned at “0”, the shutter speed cannot be changed even if the mode switch is set to
the position “7” and the UP/DOWN switch is manipulated. (The shutter is always OFF where shutter switch = “0”.)

(!) When the setting of “ Enabled/disabled for pulse width control” is not set to be “ENABLED”, the pulse width control is
not effective even if the shutter switch is set to the position “9” for the asynchronous shutter operation. In this case, the
preset shutter in asynchronous shutter mode is effective.

Vsub voltage
(VSUB)
<* C>
Increase in voltage
Decrease in voltage
•
(Note)
Vsub voltage is appropriately adjusted before shipment, and therefore the setting value should
not be changed
unless there is some particular reason
.
If the value is changed by mistake, it can be reset to the factory default by executing “(6-9) Read out of factory
default”.
[Explanation] Vsub voltage
Vsub voltage is the bias voltage (substrate voltage) that serves to control the blooming effect (resulting in blur or running
image at a saturating area) that arises from excessive light getting into CCD.
If a high Vsub voltage is set, the blooming effect can be reduced, although an excessively high voltage leads to a
narrower operation range of CCD because it is associated with a decrease in the saturating voltage of the CCD output.
It is appropriately set before shipment because the optimum Vsub voltage varies by CCD.
