6)Focusing
FocusingthelensoftheWAT-902Hisachievedwhilelookingatthemonitorscreen.
NOTE: Incaseswhentheunitcannotbefocusedmanually,usethefocusingadjustmentmethodsetoutbelow.
7)SelectanyrequiredshutterspeedbychangingSHUTTER⑦.
IMPORTANT NOTES ON FOCUSING
: Attach the required lens on the WAT-902H and loosen the hexagonal screws③. (3pcs.)
Be extremely careful not to drop the lens.
: Set the focus ring to the infinitive (∞) position, and while looking at the monitor screen, move the lens forwards or
backwards to focus.
: Tighten the hexagonal focusing adjustment screws③ (3pcs.) when focusing is completed.
IMPORTANT NOTES FOR USAGE OF AUTO IRIS LENS
: An optimal picture may not be obtained on the monitor screen due to the different kinds of lenses used which give
different angular views and different contrasts of objects. In this case adjustment must be made by reading through as
shown below.
①Check that the required auto iris lens has the adjustment control as shown in the drawing on
the left.
②Set the ALC(Automatic Level Control) adjustment control in the center between AV and PK
on the lens using a small screw driver.
③Point the lens towards the object while looking at the screen.
Turn the LEVEL adjustment control clockwise or anti-clockwise to obtain the optimal
brightness of an object on the monitor screen.
④Turn the ALC adjustment control towards PK when the contrast of the object needs to be stronger or towards AV when
it needs to be weaker.
⑤Continually repeat the procedures ③ and ④ to obtain an optimal picture.
EXAMPLE FOR SHUTTER SWITCH USE
ON: When a fixed lens without auto iris function is used.
When brightness of an object is continually variable such as continuous monitoring of the
outdoors through a 24 hour cycle.
OFF: When an auto iris lens is used.
When an optimal picture can be obtained on the monitor screen in conditions that light is less
variable such as indoors.
FL: When a flickering phenomenon on the monitor screen is caused by a source such as
fluourescent or mercury lighting.
NOTE: Select the most appropriate function out of the above three that correspond to your required monitoring.
: Smear phenomenon (a portion of an object with high brightness projecting bright trails up and down) appear
on the monitor screen, when an object with high brightness is monitored. (especially in the ON position) This dose
not mean the camera is damaged. This is normal.
8)AGCLo/Hi⑨ switch

The⑨ switchmustbesettotheLoposition,whenimprovementofS/N(Signal/Noiselevel)isrequired.Inthiscase,
theAGCrangecorrespondstothelenssetatthreestopssmaller.

The same operation as the above is carried out at the ON position of the SHUTTER ⑦
switch even when an iris-fixed lens.
The left drawing shows the area where the light intensity can be measured by the Back
Light Compensation function in the field of view. Namely the area indicated by the middle
square and lower 3 squares in the drawing on the left applies the area operative by the
Back Light Compensation function.
