7. ADJUSTMENT
1. Switch on the camera power after completing camera connections.
Power is supplied to the camera.
2. Normally,set the Shutter Speed switch to "1/60"(NTSC) or "1/50"(PAL) position.
Flickering of the picture may interfere with the view under fluorescent lamp in the area with power frequency
of 50 Hz(NTSC) or 1/60(PAL). In such cases, set the switch to "1/100"(NTSC) or "1/120"(PAL) position, and
the image free from flickering can be obtained.
Note
If the Shutter Speed switch of the Mode Setting switch is set to the ON position, sensitivity is reduced
compared to operation in the OFF position. When using the camera in a dark location, or where light flicker is
not an annoyance, set the switch to the OFF position.
3. Connect the monitor to the Monitor Output terminal to permit a picture to be viewed on the monitor.
4. Adjust the camera angle.
Camera angle can be adjusted for up to 130º(± 65º) for horizontal rotation, for up to 140º(± 70º) for vertical
rotation, and for up to 180º(± 90º) for picture tilting.
5. Adjust the angle of view with the Zoom ring and adjust the focus with the Focus ring for the best possible
picture reproduction. After lens adjustment completion, tighten both the Zoom ring fixing screw and the
Focus ring fixing screw.
Notes
• Since the Iris control is factory-preset to an optimum position for general use, avoid tampering with it in
normal conditions. Turning the control unnecessarily could cause reduced picture quality or equipment
failure. When the Iris control needs to be readjusted to match a specific subject, first set both the Adjustment
switch and the Backlight Correction switch of the Mode setting switch to the OFF position, then adjust the
control to an optimum level. After adjustment, place a hand over the lens for several seconds and then
release to check the lens for correct iris operation.
• If the focus is adjusted for a subject under good lighting conditions, the subject may go out of focus when
conditions become dark. To avoid this, adjust the lens focus after setting the Adjustment switch of the Mode
setting switch to the ON position. Be sure to switch it back to the OFF position after completing lens
adjustment.
6. Attach the dome cover to the camera after completing all necessary adjustments.
