Easy Focus adjustment
Be sure to adjust the lens focus only in a well-lit environment. When using a DC iris lens, set the
auto-iris mode switch (10) to AES, and then make the focus adjustment. After the adjustment, be
sure to return switch (10) to DC.

input
terminal
Use a DC 12 V (10.8 to 13.2 V) or AC 24 V (21.6 to 26.4 V, 49 to 51 Hz) power supply. Caution:
Use only with a 24 V AC power supply marked class 2 or +12 V DC power supply.
(13) B/W Mode Fix terminal
The picture mode can be fixed at B/W by shorting the two contacts on the B/W Mode Fix
terminal (for details, see the figure on page 17). Fixing the picture mode at B/W can prevent the
picture from having optical oscillation, a phenomenon in which continuous switching between
color mode and B/W mode occurs under infrared illumination.
Instructions when using an infrared lamp
Always check the brightness of an infrared lamp which is to be used with this product. Excessive
infrared illumination may cause optical oscillation. Refer to section (C) above and fix the picture
mode at B/W in order to avoid optical oscillation under excessive infrared illumination.
