4) Connect ⑦VIDEO OUT on the WAT-525EX2/535EX2 with the monitor,
using a coaxial cable with 75Ω impedance, such as an RG-59 or an
RG-6/U. Select a monitor with the same television system as theWAT-525EX2/535EX2: EIA or CCIR. A monitor with more than 600TV
lines is recommended.
5) Insert the power plug of the power adaptor to ⑧POWER IN on the backpanel of the WAT-525EX2/535EX2. Confirm that the power adaptor is
not connected before insertion of the power plug into ⑧POWER IN.
6) Turn on the power to the WAT-525EX2/535EX2, the monitor and all otherallied equipment. When a picture cannot be obtained on the monitor, or a
problem occurs, 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 ④FOCUSING ADJUSTMENT SCREWS

Power Supply
Use a stabilized power adaptor designed for DC+12V±10%, with a current
capacity of more than 250mA.
Use the optional DC plug if the shape or polarity of the DC plug of the power
adaptor to be used is not compatible with the camera (See the drawing on
the right below).
CautionThe 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 afterwiring. If the above care and attention is not adhered to,damage to the WAT-525EX2/535EX2 and power
adaptor may occur and may also cause fire.

10) Set the gain control to any required environment.
For AGC, turn the AGC control anti-clockwise to thelocking position. AGC automatically adjusts to arange between 5 to 32dB(HI)/5 to 20dB(LO).
With MGC, gain is manually adjusted in a range
between 5 to 32dB. In a low light environment,
when illumination of the object is important,increase the manual gain. Lower the gain control
for a clearer picture with less noise.
11) When the external sync. function is required, input the composite videoor the composite sync. signal to ⑨SYNC IN. The range of the level forcomposite sync. is 0.2 to 5.0V(p-p). The camera has a resistance of10kΩ. When more than 75Ω termination is required for impedance
matching, add the additional Ωs to the external sync. signal line.
