7. ABOUT THE LENSES
7.1. Lens (optional) Selection and Camera Setting
●
When using the flickering-reduction function outdoors or under the fluorescent lighting in the area with the
power frequency of 50 Hz, use the auto-iris lens. Follow the procedure below to perform the setting:
1. Set the Lens Auto/Manual selector switch of the mode switch
⑥
to "AUTO" position (factory-preset
position).
2. Set the lens selector switch
⑤
to "DC" or "VIDEO" position depending on the type of auto-iris lens to use.
Factory-preset for "DC" position.
3. To reduce flickering, set the flickering-reduction switch of the mode switch to "1/120" position . Factory-
preset for "(1/50)" position.
●
When using the flickering-reduction function indoors or in locations where the lighting condition does not
much change, you can use the manual or fixed iris lens by making the following camera settings:
1. Set the Lens Auto/Manual selector switch of the mode switch
⑥
to "MANU" position. Factory-preset for
"AUTO" position.
2. Set the flickering-reduction switch of the mode switch to "(1/50)" position. Factory-preset for "(1/50)"
position.
Notes
●
When the flickering-reduction switch is set to "1/120" position, the automatic
sensitivity adjustment function cannot be used even if the Lens Auto/Manual
selector switch of the mode switch is set to "MANU" position. Use the auto-iris
lens.
●
To avoid damaging the internal sections of the camera's lens mount, be sure
that the lens flange is less than 5 mm thick as illustrated on the right.

C-mount lenses must be used in conjunction with the Lens Mounting Adapter
CF-5 (optional).
