C • B/W (colour/black and white) switch setting
This switch lets you select the timing of the automatic switching of
the optical filter to colour image or black and white image, according
to the subject brightness. The default setting is "L". Set the switch
according to the brightness.
H: for a brighter setting than L
L: Standard setting
After the power has been turned off, switching will restart from
colour, when the power is restored.
A sound may be heard when the colour image or black and white
image is switched. Also, the image will be distorted as shown in
Fig. 1, this is normal and does not indicate a problem.
When using infrared lighting, if there is a strong reflection on the
subject, the optical filter may switch from black and white to
colour mode, Use only enough infrared lighting so that the mode
is not switched.
The focus setting may be different in black and white mode and
colour mode. Please check the focus setting in both modes.
