IMPORTANT NOTES ON ⑮SHUTTER SPEED selector

When a strong spot beam is shone directly onto the lens when ⑮SHUTTER SPEED selector is set at EI

(Electronic Iris) and/or at a high speed shutter position, smearing may appear on the monitor screen. (This is not abnormal or considered defective in any way).

In addition, when using fluorescent or mercury lighting at 50Hz or 60Hz the following phenomenon may appear.

Frequency of commercial power supply 50Hz

Frequency of commercial power supply 60Hz

NTSC 1/60

Phenomenon 2

Phenomenon 1

Phenomenon 1 : The higher the shutter speed selected, the more conspicuous the flickering will appear on the monitor screen.

Phenomenon 2 : Cyclic change of color may appear on the monitor screen. The change of color becomes greater, when a high shutter speed is selected.

When the above phenomena is present, operate the camera with ⑮SHUTTER SPEED selector set to the

OFF position. An Auto Iris Lens is recommended or replace the illumination device with a high frequency light source.

FL (Flickerless) : This function is useful for reducing the flickering phenomenon on the monitor screen caused by such lighting sources as fluorescent or mercury lamps.

N. B.

This feature is only effective at 50Hz using NTSC equipment and 60Hz using PAL equipment and when a standard power supply is being utilized.

8.

⑦WHITE BALANCE selector

Select any required white balance settings by ⑦WHITE BALANCE selector to one of its 6 positions available. ⑦WHITE BALANCE selector has been set to AUTO upon shipment.

IMPORTANT NOTES ON ⑦WHITE BALANCE selector

The AUTO or P.W.B. is effective when the 4 automatic settings (sunlight, fluorescent 1, fluorescent 2, and incandescent) are not suitable for the lighting conditions. The AUTO is effective when lighting conditions are constantly changing such as night and day outdoor surveillance.

On occasions, it may be difficult to get optimal White Balance adjustment in low light conditions.

Especially when fluorescent and mercury lighting being used are inexpensive and/or not conforming to certain recommended industrial standards.

Adjustment of the white balance when set at P.W.B. is especially effective when white objects are being monitored on the whole screen such as paper or a large area such as a wall.

The P.W.B. can be used in almost all lighting conditions, however the P.W.B. mode is not provided with a function that can cope with changing color temperatures (light conditions) automatically.

In this case, the image can be adjusted by pressing and releasing the button at intervals.

Both P.W.B. and M.W.B. operations, adjusts the White Balance automatically and is memorized. The setting of ⑦WHITE BALANCE selector in the position is recommended to protect misoperation of any of (R) and (B) push buttons after the final and optimal adjustment of the color temperature.

9.

When back light compensation (light that falls onto the back of an object being monitored) is required, set the ⑩BACK LIGHT (ON/OFF) to the ON position.

IMPORTANT NOTES ON ⑩BACK LIGHT (ON/OFF)

The back light compensation function is to reduce the dark image of an object (silhouette) when it is monitored. The back light compensation switch when used in combination with ⑮ SHUTTER SPEED selector provides the following functions.
