Introduction

Operating Precautions (continued)

●The white balance (ATW) of this device is optimally set for sunlight. Proper white balance may not be achieved for artificial lighting such as fluorescent lighting, etc.

●If you use this camera in locations where the camera is exposed to fluorescent light, a slow color change may occur.

(White balance normal = 5,400 K, range is 2,500 K to 10,000 K.)

●AGC HIGH(⋅2) and up: in this mode, ATW white balance may be inaccurate.

●White balance performance decreases under poor lighting condi- tions.

●Observe the following when carrying out camera maintenance.

• Turn the power OFF before proceeding to carry out maintenance. If it is contaminated seriously, clean the contaminated part with a cloth (or a tissue) which has been soaked in a solution of water and a neutral detergent.

●The unit is to be powered by a DC 12 V or an AC 24 V power supply. The AC 24 V power supply should conform to the following:

U type : Class 2 only

E type : Isolated power supply only

●The beat may sometimes appear on the screen if gain is raised when the line lock is in use, but the phenomenon takes place due to the fluctuation of power frequency and is not a malfunction.

●At Low light levels, video iris lens may “Hunt”. Please adjust iris level on lens to minimise hunting.

●Recommended range of operating temperature is 0°C to 35°C de- grees. The camera will function outside these parameters to –10°C to 50°C degrees. But processing errors may be apparent.

●Line-Lock is set for 50 Hz ±0.02 Hz. If line frequency is outside this tolerance, picture may jitter and some interference may be visible in high contrast scenes.

●At low light level, when the slow shutter functions the screen may be tinted.
