Operating Precautions (continued)
● The white balance (ATW) of this device is optimally set for sun-
light. 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 ex-
posed 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 SUPER: in this mode, ATW white balance may be inaccurate.
● White balance performance decreases under poor lighting con-
ditions.
● Observe the following when carrying out camera maintenance.
• Turn the power OFF before proceeding to carry out mainte-
nance.
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 malfunc-
tion.
● 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
degrees. The camera will function outside these parameters to
–10°C to 50°C degrees. But processing errors may be appar-
ent.

● 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.
● Blemishes: Small spots are normal, the camera contains com-
pensation functions for blemishes above 120 mV (p-p) in value.
Please contact your JVC authorised dealer for further informa-
tion.
