6.7 LENS menu

Lens can be selected as either DC (Auto Iris) or MANUAL (Disabled A/I function).

To enter DC/MANUAL LENS menu, press ● button at MAIN >LENS>DC(MANUAL).

BRIGHTNESS can be adjusted. It takes about 5 seconds for brightness to settle

after the adjustment.

CAUTION b

Be careful NOT to overly decrease the BRIGHTNESS. If the DC iris is set too

low, it may cause difficulty for the camera when it returns from NIGHT to DAY due

to diminished or incidental light .

6.7.1 FOCUS ADJ. menu

Sometimes the focus - when adjusted in very bright daylight - becomes blurry at

night. This condition is commonly referred to as "Focus Shift". The FOCUS ADJ.

menu is used to assist with easy adjustments to sharpen the image with the use of

ZOOM and FOCUS eliminating this kind of error by simulating the conditions of

night time. D/N DWELL is used to adjust the period between switching from Color

(day) to ICR (night).

Set the ZOOM first and then adjust the FOCUS precisely in order to achieve a

sharp image while

switching between day and night modes.
