Cautions for Safety
The WAT-902HB series is designed to be used safely; however, it may lead to a
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-902HB series.
Danger
• Do not operate the WAT-902HB series with wet hands.
• Use a stabilized power adaptor designed for DC+12V±10%,
Warning
with a current capacity of more than 250mA for the
WAT-902HB series.
The recommended voltage is DC+12V±10%
• Do not expose the WAT-902HB series to wetness or high
moisture conditions.
The WAT-902HB series is designed and approved for indoor use
only. The WAT-902HB series 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-902HB series from condensation.
Keep the WAT-902HB series 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 WAT-902HB
Caution
series.
The WAT-902HB series uses high quality electrical parts and
precision components.
• Do not connect any power supply directly to the video
out terminal of the unit.
Do not connect the WAT-902HB series with any monitor using a
video/power single transmission terminal. The WAT-902HB series
is not designed for use with this type of equipment. We also advise
you to read the operation manual of the monitor you plan to use
before any connections are made.
• Do not install the WAT-902HB series in a position subject to
direct sunlight.
Sunlight shinning directly onto the WAT-902HB series lens can
cause damage to the CCD.
• Select a stable place for installation of the WAT-902HB series.
Always fix the camera securely. See【Mounting Holes】section.
• Do not move the WAT-902HB series with the cables
connected.
Before moving the WAT-902HB series, always remove the video
cable and power cable from the camera first.
• Avoid using the WAT-WAT-902HB series near any strong
electromagnetic field.
After installing into main equipment, if the WAT-902HB series is
exposed to electromagnetic waves causing the monitored image to
become distorted, we recommend the camera be shielded by
appropriate protective casing.
Problems and Trouble Shooting
If any of the following problems occur when using the WAT- WAT-902HB
series,
• An optimal picture cannot be obtained, after checking that all the cables and
connections are correctly in place
• Smoke or any unusual odor emerges from the WAT-902HB series
• An object becomes embedded or a quantity of liquid seeps into the camera
• More than the recommended voltage or/and amperage has been applied to the
WAT-902HB series by mistake
• Anything unusual occurring to any equipment connected to the WAT-902HB
series.
Disconnect the camera immediately according to the following procedures:
①Switch off the main power supply to the camera.
②Remove the power and video cables connected to the WAT-902HB series.
③Contact the distributor or dealer from which the WAT-902HB series was
purchased.

Description of Parts
①LENS FRONT FACE
・The light receiving face of the lens
(Dirt, water or oil deposits on the lens will cause an unclear picture on the
monitor. Attach the lens cap to protect the lens from contamination and
damage.)
②LENS MOUNT
・Mount for the lens (Thread type)
③FINE FOCUS ADJUSTING SCREWS
・There are 3 hex. adjustment screws each placed at intervals of 120゜for fine
focusing of the lens.
④POWER IN/VIDEO OUT
・The terminal for power input and video signal output. Use the attached
connector with cables for this purpose.
⑤TERMINAL FOR AUTO-IRIS LENS (VIDEO CONTROL)
・The terminal for a Video-driven auto-iris lens. Do not connect a DC-driven
auto-iris lens to this terminal.
⑥MOUNTING HOLES
・Holes for mounting the camera.
⑦AGC SELECTION SWITCH
・Switch for setting AGC HI or LO
Power Supply and Wiring
Use a stabilized power adaptor designed for DC+12V±10%, with a current
capacity of more than 250mA.
The wiring on the connector must be exact.
Be careful not to touch the other terminals while wiring. Protect the wired portion
by using insulation tape. If the above care and attention is not adhered to,
damage to the WAT-902HB series and power adaptor may occur and may also
cause fire.

Mounting Holes Mounting Holes
As shown in the figure on the right. The WAT-902HB series
provides four mounting holes(φ2.2mm), one in each corner of
the circuit board. Fix the unit securely using M2 screws. Once
the board is secured proceed with the following steps below.
Set-up and Operation
1) Ensure that the power to the WAT-902HB series and the peripheral equipment
is turned off before making any connections.
2) Remove the lens mount cap from the WAT-902HB series.
3) When an auto iris lens is being used, connect the cable to ⑤TERMINAL FOR
AUTO-IRIS LENS.
※Do not connect a DC control iris lens to this camera.
4) Connect the attached cable to ④POWER IN/VIDEO OUT. See the【Power
Supply and Wiring】section.
5) Connect a coaxial cable with 75Ω impedance, such as an RG-58/U or an
RG-6/U to the monitor. Select a monitor with the same television system as
the WAT-902HB series: EIA or CCIR. A monitor with more than 600TV lines is
recommended.
6) Turn on the power to the WAT-902HB series, monitor and all other allied
equipment. When a picture cannot be obtained on the monitor, check and
follow the procedure mentioned in the【Problems and Trouble Shooting】
section.
7) After following the procedure below and the picture is still out of focus, open
the iris fully and loosen ③FOCUSING ADJUSTMENT SCREWS with the hex.
