Problems and Trouble Shooting

DangerWarning

Caution• Do not disassemble and/or modify the WAT-902HB series.
• Do not operate the WAT-902HB series with wet hands.
• Use a stabilized power adaptor designed for DC+12V±10%,with a current capacity of more than 250mA for theWAT-902HB series.
The recommended voltage is DC+12V±10%• Do not expose the WAT-902HB series to wetness or highmoisture 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 likeenvironment, 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 andoperation.
• 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
series.
The WAT-902HB series uses high quality electrical parts andprecision 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 avideo/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 todirect sunlight.
Sunlight shinning directly onto the WAT-902HB series lens cancause 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.

Black: Common GND• An optimal picture cannot be obtained, after checking that all the cables andconnections 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 theWAT-902HB series by mistake• Anything unusual occurring to any equipment connected to the WAT-902HBseries.
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 waspurchased.

Cautions for Safety
The WAT-902HB series is designed to be used safely; however, it may lead to aphysical 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.

The wiring on the connector must be exact.
Be careful not to touch the other terminals while wiring. Protect the wired portionby 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■AGC

As shown in the figure on the right. The WAT-902HB series
provides four mounting holes(φ2.2mm), one in each corner ofthe circuit board. Fix the unit securely using M2 screws. Oncethe 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【PowerSupply and Wiring】section.
5) Connect a coaxial cable with 75Ω impedance, such as an RG-58/U or anRG-6/U to the monitor. Select a monitor with the same television system asthe WAT-902HB series: EIA or CCIR. A monitor with more than 600TV lines isrecommended.
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 andfollow 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.
wrench and move the lens forwards until a clear picture is obtained.

・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.

※When the function is returned to electronic iris mode, be sure to reinstall theresistor. Therefore, we recommend safe keeping of the resistor.
