OPERATION MANUAL

INTRODUCTION:

Thank you for choosing our WAT-535EX CCD camera.
Watec hopes that both the quality and design satisfy your requirements.
Before proceeding to install or operate the WAT-535EX, please read the contents of the Operation Manual thoroughly to ensure
proper usage and understanding of our product. For future reference we also advise safe-keeping of this manual.

CAUTIONS:

1. Use only the AD-901 or equivalent power adaptor for the WAT-535EX. (Power supplied without voltage stabilization and/or

voltage range maintained at ±10% 12V DC may cause damage.)

2. Do not expose the WAT-535EX to wetness or high moisture conditions. The WAT-535EX is designed and approved for
indoor use only. For outdoor use or outdoor like conditions, we recommend that a special camera housing is installed for
adequate protection.

3. Avoid striking the unit with hard objects or dropping the unit.

4. Do not disassemble and/or modify the WAT-535EX, or its component parts or accessories. Watec can not be held responsible
for equipment operation failure or any damage and/or trouble caused by such action.

5. Do not install the WAT-535EX near heat sources, such as radiators or heating air ducts, or in a place subject to direct sunlight
※, excessive dust, mechanical vibration or shock.

6. When installing the WAT-535EX in an industrial or commercial environment (i.e., within equipment housing, near other
electronic device, etc.) make sure to avoid any strong electromagnetic field, otherwise, the video output may be distorted and
monitor clearness compromised.

7. Do not connect any power supply directly to the terminal of the VIDEO OUT/SYNC IN connector. This may cause damage.

8. When a cable operation system is being used (video signal/power coaxial cable transmission), check the specifications of
your monitor for proper connection to the video signal terminal of the camera.

9. Do not make connections and/or operate the WAT-535EX with wet hands.
Should the WAT-535EX not work properly, switch off the power and then, check all the required connectors, power cable,

*The WAT-535EX is compatible with both a Video iris lens and a DC driven iris lens. (Patent pending)

3. Connect ⑦VIDEO OUT on the WAT-535EX with the monitor, using a coaxial cable with 75Ωimpedance, such as an

RG-58/U or an RG-6/U.

IMPORTANT NOTE: Select a monitor with the same transmission mode as the WAT-535EX, there are two versions, NTSC

and PAL. A monitor with more than 700TV lines is recommended.

CAUTION: Do not use a monitor which uses a video signal/power coaxial transmission cable.

4. Insert the power jack of the power adaptor to ⑧POWER IN on the back panel of the WAT-535EX.
NOTE: Confirm that the power adaptor is not connected before insertion of the power jack into ⑧POWER IN.

The optional Watec power adaptor, AD-901 (DC 12V, 250mA) is recommended.

IMPORTANT NOTE: When not using a recommended Watec Power Adaptor:
A. Use a stabilized power adaptor with a voltage range of 12V DC, ±10% and a current capacity of

more than 250mA.

B. Use the additional DC power jack, when the shape or polarity of the power jack of the DC power

adaptor can not be inserted into ⑧POWER IN on the WAT-535EX.

C. Wire the DC Power jack as appropriate. Use the drawing on the right to guide you.

5. Switch on the WAT-535EX, monitor and all other allied equipment.

Remove the power jack of the AD-901, AC adaptor at once whenever the picture does not appear on the monitor.

6. Focusing the lens of the WAT-535EX is achieved by adjusting the lens while looking at the monitor screen.

N.B. In cases when the WAT-535EX can not be focused manually, use the focusing adjustment method set out below.
・Attach the required lens on the WAT-535EX and loosen the three hexagonal focusing adjustment screws.

*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 ④Hexagonal focusing adjustment screws when focusing is completed.

7. GAIN CONTROL: Turn according to your requirements.
The optimal picture can be obtained under various environments when GAIN CONTROL on the back panel is turned
clockwise or anti-clockwise as shown below on the left;

・Gain corresponding to the brightness of an object is automatically adjusted in a range between 5dB - 32dB when GAIN

CONTROL is locked in the AGC position.
*When AGC is set at AGC LO, brightness of an object is automatically adjusted to a range between 5dB - 20dB.

・When using the MGC function (after unlocking GAIN CONTROL clockwise ), the gain can be manually fixed in a range

between 5 - 32dB.

・When a high S/N is required in low fluctuating brightness situations, lower the gain by

turning GAIN CONTROL anti-clockwise so as to be able to obtain the best optical
picture, then adjust the iris function on the lens to the lighting conditions.

・When there is a dark environment, in low fluctuating brightness situations, increase

the gain by turning GAIN CONTROL clockwise.

・When a wide depth of field is required, first turn the lens iris towards the closed

position, then adjust the gain using GAIN CONTROL.

8. Select any required shutter speed by the Sutter speed selector to one of its 9 positions when required.

*When an object with high brightness is focussed upon (especially on shutter operation), smearing phenomena may appear on

the monitor. This does not mean damage has occurred to the WAT-535EX.

9. Select any required functions by setting four Function Switches at upper or lower positions.

Note: How to dismount the lower housing cover of the WAT-535EX

・Switch off the power.
・Remove the four fixing screws from the housing cover.
・Slowly side the housing cover away downwards from the main unit.
・For replacement, repeat the above procedure in reverse.

CAUTION: Change any required switch setting firmly to avoid any operational or functional instability of the camera.

How to set

Function SW:

・For producing the best possible results, adjust the switches to meet your requirements while taking

into consideration the use of the WAT-535EX, the environment and the desired picture quality.

10. When external synchronization is required, insert the synchronization signal jack into the ⑨SYNC IN, BNC terminal.

*The signal required for input is C.SYNC or C. Video using 0.2 to 4Vp-p.
*The input resistance of the WAT-535EX is 10K Ω, but when 75Ω is required, the external synchronization signal

cable must be terminated to earth. In this case, the input voltage is the same as the above.

*The WAT-535EX is set at internal synchronization. When a synchronized signal is received by the camera it will

adjust automatically to external synchronization.
