Restart/Reset

The information on one screen can be extracted at

any time by externally inputting restart/reset signals

(HD/VD). To enter this mode, set the trigger shutter

switches (6 to 8) on the rear panel of the camera as

shown in the figure below.

To use restart/reset mode and partial scan mode

simultaneously, set the partial scan mode switch (5)

to ON (right side).

Long exposure

The Restart/Reset function extends the CCD

accumulation time, resulting in highly sensitive

image capture. This function is effective when you

cannot gain satisfactory sensitivity under normal

operating conditions, or when you want to observe

the trail of a moving object. Extend the VD interval

(T) between external VD pulses.
