Cautions for Safety
The WAT-250D2 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-250D2.
•
Do not operate the WAT-250D2 with wet hands.
•
Use only the AD901-120/230 or equivalent power adaptor
for the WAT-250D2
The recommended voltage is DC+12V
±
10%.
•
Do not expose the WAT-250D2 to wetness or high
moisture conditions.
The WAT-250D2 is designed and approved for indoor use only.
The WAT-250D2 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-250D2 from condensation.
Keep the WAT-250D2 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-
250D2.
The WAT-250D2 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-250D2 with any monitor using a
video/power single transmission terminal. The WAT-250D2 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-250D2 in a position subject to
direct sunlight.
Sunlight shinning directly onto the WAT-250D2 lens can cause
damage to the CCD.
•
Select a stable place for installation of the WAT-250D2.
Use a support of durable strength around an installation
position on a ceiling or wall when a camera stand or tripod is
used.
•
Do not move the WAT-250D2 with the cables connected.
Before moving the WAT-250D2, always remove the video
cable and power cable from the rear of the camera first.
•
Avoid using the WAT-250D2 near any strong
electromagnetic field.
After installing into main equipment, if the WAT-250D2 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-250D2,
•
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-250D2
•
An object becomes embedded or a quantity of liquid seeps into the
camera housing
•
More than the recommended voltage or/and amperage has been applied
to the WAT-250D2 by mistake
•
Anything unusual occurring to any equipment connected to the
WAT-250D2
Disconnect the camera immediately according to the following
procedures:
①
Switch off the main power supply to the camera.
②
Remove the power and video cables connected to the WAT-250D2.
③
Contact the distributor or dealer from which the WAT-250D2 was
purchased.

the right).
The wiring on the connector must be exact.
Be careful no to touch the other terminal while wiring.
Protect the wiring portion by using insulation tape after
wiring. If the above care and attention is not adhered to,
damage to the WAT-250D2 and power adaptor may
occur and may also cause fire.
