4-4 Operator's Manual LDK 23HS mkII - HS Camera System Location of Controls and Functions
1
VTR switch
The VTR switch is disabled in this mode. In triax mode
however, it will switch the microphone of the headset
to the production intercom channel.
2
Vertical Shift switch (V-Shift)
The V-Shift switch is disabled in this mode.
3
Clean Scan button (CLS)
The camera does not have a ‘clean scan’ facility.
Although it is possible to select a variable exposure
time between 151/181 to 829 Hz, it is not possible to
increase it above the nominal setting (1/150 of 1/180).
Therefore, it is not possible to eliminate the horizontal
bars when shooting monitors with this camera because
their refresh rates are below 150Hz.
4
Auto White Balance button (AWB)
The AWB button is a momentary switch, used to start
the automatic white balance process. The camera,
when pointed at a white area in the centre of the
picture, measures and stores a colour temperature
setting in the AW1 or AW2 memory position.
The AWB button only operates if the colour temperature
switch is in the AW1 or AW2 position. Refer to Section
5 for more information on how to use the AWB.
5
Colour Bars button (Bars)
The Bars button is used to switch the colour bar test
signal on and off. (The lens iris closes automatically
when the colour bars are switched on.)
6
Colour Temperature switch (Col. temp)
This up/down scroll switch allows a choice between
three preset colour temperatures:
• 3200K (3.2K) - for studio lighting conditions
• 5600K (5.6K) - for outdoors, clouded conditions
• 7200K (7.2K) - for outdoors, clear blue skies
and two memory settings AW1 and AW2. These two
memory settings can be filled with measured values
using the AWB button (4).
7
Gain switch
This up/down scroll switch gives a choice between
four gain settings that, except for the 0dB setting, can
be set in the install menu (refer to section 6).

wheel moves to its next position. The filter switch has
