WARNING
•
Do not allow water into the lens. It may cause fi re or electric shock. If water enters,
shut off the power supplied to the lens immediately.
•
Do not look at the sun or any sort of strong light source through the lens. It may
harm your eyes.
CAUTION
•
Before supplying power to the lens, make sure all devices are connected correctly.
•
When connecting or disconnecting a cable, make sure to hold the connector. Do not
pull or twist the cable, or it may get damaged. Damaging a cable may cause fi re or
electric shock.
•
Do not leave or store the lens under direct sunshine. The lens may converge light on
a near-by object and cause a fi re.
•
In the event of unusual smoke or smell, abnormal noise or if foreign objects are found,
shut off the power supplied to the lens, remove the lens from the camera immediately
and contact the dealer where you purchased this product or service shop.
•
Do not disassemble or remodel the lens without permission. It may impair the lens
functions, or cause electric shock.
NOTICES
•
The lens is precision instruments. Make sure not to apply strong impacts on them.
•
Mist may form on the lens when it is suddenly moved from a cool place to a very
hot and humid place. When moving the lens to such environment, take preventive
measures such as adapting the lens in advance to the ambient temperature of the
place where it will be used.
•
When storing the lens, avoid hot and humid places as well as places where there is
corrosive gas.
•
When not using the camera for a long time, put the cap on the lens.
This CCTV lens produces high-definition images from the center to the marginal
area on monitor as a result of the adopted aspherical lens and highly advanced
optical design technology. This is an optimum vari-focal lens for high-quality
image surveillance, even when used with an ordinary CCTV or mega-pixel camera.
Note: This lens is designed for CS mount cameras and cannot be used with C mount
cameras.
The iris of this lens cannot be controlled with Video signals. Make sure to use
this lens with a camera that can output DC signals.

Mounting the Lens
Press the threaded portion of the lens mount against the threaded portion of the
camera mount and slowly rotate the lens clockwise. Screw the lens firmly to the
camera.
Note: The lens mount is equipped with a slip mechanism. To change the rotational
direction of the lens to adjust the iris cable position, rotate the lens further
clockwise. If the lens reaches the stopper before the cable position is adjusted
and it cannot be rotated further, adjust by slowly rotating the lens counter-
clockwise.
Lens Maintenance
The lens surface is treated with antireflective coating. Dirty lens surface due to
dust, oil, fingerprints and the like causes harmful flare which results in lower lens
performance. Since dirt on the lens may contribute to tarnishing as well as formation
of mold, clean as indicated below whenever the lens is found to be dirty.
•
Dirt and dust
Gently remove dirt and dust with an oil-free, soft brush or blower brush (for
photography use).
•
Water droplets and oils
Gently wipe water droplets or oil with a clean, soft cloth and dry. Put some isopropyl
alcohol or lens cleaning solution onto an oil-free, washed-out cotton cloth or lens
tissue and gently wipe with circular motion, from the center of the lens toward the
edge.
