RESTART RESET (R.R)
The information on one screen can be extracted at any time by inputting a restart/reset signal (HD/VD) from the outside. To enter this mode, set DIP switches 6, 7, and 8 on the rear panel of a camera as shown in the table below. The setting is especially effective for the following operation.
Switch 1 2 3 4 5 6 7 8 Restart Reset (R.R) 0 0 0 0 0 1 1 1

Long exposure
A high-sensitivity image is obtained by extending the exposure time of the CCD when satisfactory sensitivity cannot be obtained under other operating conditions or when observing the trail of a moving object. The exposure time is determined by the VD interval (T) period between external VD pulses as follows.
� Timing and conditions
Example 1 of Long exposure
EXT HD
Continuous signal: 15.734 kHz (XC-ST70), 15.625 kHz (XC-ST70CE) Allowable frequency value ±1%
EXT VD
VD interval(T): 262.5H or more (XC-ST70), 312.5H or more (XC-ST70CE) and less than 1 second (Recommended) Four or more VD pulses are required. T T T
Exposure time for Odd field Exposure time for Even field
Video output
Odd image Invalid image Even image Valid frame image
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
