may incur injury and cause damage to peripheral objects in the
immediate surroundings.

The WAT-231S2 is designed to be used safely; however, it may lead to
physical accident caused by fire and electric shock if not used correctly.
Therefore, please keep and read the “Cautions for safety” below for
protection against accidents.

•

Do not disassemble and/or modify the WAT-231S2.

•

Do not operate the WAT-231S2 with wet hands.

•

Use only the AD901-120/230 or equivalent power adaptor
for the WAT-231S2.

The recommended voltage is DC+12V±10%

•

Do not expose the WAT-231S2 to wetness or high moisture
conditions.

The WAT-231S2 is designed and approved for indoor use only.
The WAT-231S2 is not water-resistant or waterproof. If the
location of the camera is outdoors or in an outdoor like
environment, we recommend that you use an outdoor camera
housing.

•

Protect the WAT-231S2 from condensation.

Keep the WAT-231S2 dry at all times during storage and
operation.

•

Should the camera not work properly, switch off the power
immediately. Then check the camera according to the
“Problems and Trouble shooting” section.

•

Avoid the striking of hard objects or dropping the WAT­231S2.

Set-up and Operation

1) Ensure that the power to the WAT-231S2 and the peripheral equipment is
turned off before making any connections.

2) Remove the lens mount cap from the WAT-231S2 and attach the
CS-mount lens. Use the optional C-mount adaptor (34CMA-R) when a
C-mount lens is used.

3) Connect the iris control cable to ⑤AUTO-IRIS SOCKET on the WAT­231S2 when an auto-iris lens is being used.

4) Connect ⑩VIDEO OUT on the WAT-231S2 with the monitor, using a

coaxial cable with 75Ω impedance, such as an RG-58/U or an RG-6/U.

If the monitor has an S-terminal, high resolution imaging is possible by
connecting with ⑪Y/C OUT.

※The ⑪Y/C OUT can be used together with the ⑩VIDEO OUT.
※Select a monitor with the same television system as the WAT-231S2

12) Correction of white blemish by ⑯WHITE BLEMISH CORRECTION
BUTTON. The WAT-231S2 is manufactured using high-grade CCD
devices that are selected by tough standards by the manufacturer.
However, it is impossible to prevent the white blemishes from occurring
after shipment because the white blemish phenomena can be caused
by cosmic rays. The WAT-231S2 has a white blemish correction circuit
to help control the white blemish phenomena. Correct according to the
following procedures, if white blemishes are present.

[PROCEDURE]

1. Completely cover the lens to prevent light entering.

2. Set to MWB or PWB by ⑦WHITE BALANCE MODE SELECTOR

3. Set to AGC ON by ⑬FUNCTION SWITCHES

4. Press the ⑯WHITE BLEMISH CORRECTION BUTTON using a fine

stick or piece of wire.

5. After 5 seconds, the white blemishes are automatically detected, and
then recorded to the camera.

[ATTENTION]

1) Make sure that the lens is completely shielded from light before
correction of the white blemishes. If the lens is not covered properly
and light can enter into the lens on to the CCD face, the correction of
the white blemish may not be detected correctly.

2) Make sure that ⑦WHITE BALANCE MODE SELECTOR ”MWB or
PWB” is selected. If any other position is selected; the data cannot
be saved to the camera.
