0 Power Pilot LED
When lit, the LED indicates that power is supplied to the CCU.
0 POWER ON-OFF Switch
This is the main power switch of the CCU.
• GAIN (Contrast Enhancement)
This is the potentiometer to adjust the gain of the video signal
within a range of one to ten times.
Turn the GAIN clockwise and gain will be increased.
® OFFSET (Contrast Enhancement)
This is the potentiometer to adjust the offset level. Turn the OFFSET
counterclockwise and the black level will be redefined to a higher
value.
® SENSITIVITY
* Effective only with the C2400-00,-03 and -08 camera heads.
This control adjusts the sensitivity of the tube.
Turn this control clockwise and the sensitivity of the tube will be
increased.
CAUTION:
Excessive sesitivity values may cause permanent damage to
the imaging tube.
® VIDEO LEVEL
These LED indicators monitor light intensity to the camera. The
green lamp indicates an appropriate level of illumination while the
red lamp indicates excessive light intensity. In the case of the
C2400-00, -03, and -08, the SENSITIVITY potentiometer can be
used to adjust the light intensity.
C) VIDEO SELECT
This switch selects the video signal which is displayed on the TV
monitor.
The neutral (middle) position selects the normal image. The upper
and lower positions select the boosted and inverted image outputs
respectively when these options are installed.
0 SHADING ON-OFF Switch
This switch enables or disables the shading correction. When the
M2502 SHADING CORRECTOR is installed, the ON position of
the switch implements the shading circuitry.
• SHADING Correction Potentiometers
These potentiometers are utilized to adjust the shading correction
values. Use the special screwdriver for adjustment.
• CAMERA
This terminal connects the CCU to the camera head.
C) VIDEO OUT 1
This terminal outputs a composite video signal.
© VIDEO OUT 2
This terminal outputs a composite video signal identical to VIDEO
