The standard scene file button is a momentary button which, when
pressed for two seconds, recalls the standard scene file values. These

The Bars switch turns the colour bar test signal on and off. The lens iris
closes automatically when the colour bars are switched on.

Press the Clean Scan button for two seconds to directly access the
shutter angle function. Press the Clean Scan button for two seconds to
switch off the shutter angle function. (Default shutter angle is 180°.)
Exposure Time switch
This up/down momentary switch gives a choice of exposure time
settings (see Section 5 for more details). These are:
Nom. - nominal setting
CRT - position for shooting sync-locked monitors
1/200 - for fast moving objects
1/500 - for fast moving objects
50 Hz - shooting with 50Hz lighting (adjustable)
60 Hz - shooting with 60Hz lighting (adjustable)
If an exposure time other than nominal is selected, the non-standard
indicator (!) in the viewfinder lights.
Recorder Start buttons
The recorder start buttons control the recording system. The button,
when pressed initially, starts the recording system. When the button is
pressed again, it stops the recording system. These buttons operate in
parallel with each other. (If set in the Lens menu, this button can also
operate as a momentary button.)
