Operating Precautions

8WARNING

Install the unit on a strong and stable surface.

This unit has been designed to revolve at high speed. Due to its weight (about 1.3 kg) and the vibrations it may be subjected to, the camera must be mounted to a sturdy and stable material. If the ceiling material lacks strength, for example if it is made of a decorative laminated material or plasterboard, then the mount should be reinforced using materials such as veneered plywood. If such reinforcement is inadequate, images may fluctuate due to vibration or, in the worst case, the camera may fall and cause a serious accident should there be anyone below it.

For installation, use the provided ceiling mount and the optional flush mounted ceiling bracket, which is sold separately. When installing this device, the provided ceiling mount and the optional flush mounted ceiling bracket, which are sold separately should be used. Also be sure to connect the drop prevention wire and tighten all screws and nuts firmly.

Power the unit with the rated power voltage. The power rating for this unit is 24 V AC, 50 Hz/60 Hz. If a power above this rating is supplied, a malfunction will occur or, in the worst case, smoke or fire may be produced.

This unit offers a certain degree of protection against any damage either to itself or to its connection cable that might result from indirect lightning strikes, but it is not capable of preventing all damage by lightning strikes. For example it is not protected against a direct lightning strike. If lightning damage can be expected in the place where the unit is installed, be sure to take countermeasures by adding an arrester to the connection cable, etc.

To save energy, turn the system off whenever it is not in use.

This camera has been designed for indoor use. It cannot be used outdoors.

This camera has been designed to be hung from a ceiling. Do not install it in an upright position on a surface or at an angle, as this may cause a malfunction or a noticeable shortening of its service life.

Do not install or use the camera in the following locations.

In a place exposed to rain or water.

In a place containing vapor or oil soot, for example in a kitchen.

In a place outside the operating temperature range (-10Ito 50I).

Near a source of strong radio waves or magnetism, radiation or X-rays.

In a place where corrosive gassed are generated.

In a place subject to vibrations.

In a place with excessive dust.

Insufficient ventilation of the camera may cause a malfunction. Be careful not to block ventilation of the camera. This unit radiates heat from the panel surfaces (top panel and side panels). Do not install it in a place where a heat pool may form, such as near a wall.

Do not install the camera in a place exposed to cold air, for example near to the air outlet of an air conditioner. Otherwise, moisture may become condensed inside the dome cover.

Do not point the lens at a strong light source, for example under the sun. Doing so may cause the camera to malfunction.

The camera incorporates an AGC circuit. As a result, when it is used under low light conditions the camera gain may increase automatically. This makes the picture appear uneven, however this is not a malfunction.

When equipment that generates strong magnetism such as a transceiver is used near to the unit while the AGC circuit is ON, beat noise, etc may interfere with the picture. If a transceiver or similar equipment is used, keep it a distance of at least 3 meters from this unit.

In auto iris mode, when the AGC circuit is ON, varying the iris with the iris control button may not change the picture brightness. This is due to the automatic gain boost by the AGC circuit. In this case, set AGC to OFF or use the manual iris mode.

In auto iris mode, the iris control button may not function under certain brightness conditions (i.e. when a sufficient amount of light cannot be obtained). In this case, set the iris mode to manual.

When the camera is used in ATW (Auto White balance) mode, the colors captured by the camera may differ from the actual colors being shot due to the mechanics of the auto- tracking operation within the white balance circuit. However, this is not a malfunction.
