24• When misalignment of the preset positionsoccurred while the camera is in use, misalign-ment will be corrected using the position refreshfunction.The position refresh function can be assigned tothe schedule so that misalignment can be cor-rected periodically.In some situations, reconfigure the preset posi-tions.Network oper-ating instruc-tions (PDF)TroubleshootingBefore asking for repairs, check the symptoms on the following table.Contact your dealer if a problem cannot be solved even after checking and trying the solution or if the problem is notdescribed below.When using DC power supply• Is the provided DC 12 V power cord plug firmlyinserted into the DC 12 V power terminals of thecamera?Confirm that the plug is firmly inserted.When using a PoE device for power supply• Are the PoE device and the network connectoron the rear of the camera connected using aLAN cable (category 5)?Confirm the cable is firmly connected.• Depending on the PoE device, the power supplywill stop when the power demand exceeds thetotal power limit for all PoE ports.Refer to the operating instructions of the PoEdevice in use.• When the camera position is moved after turn-ing on the power of the camera, the cameramay stop in the process of panning/tilting andmechanical noise will come out from the cam-era.Execute the refresh position function from the[Initialization] tab of the "Maintenance" page.• This may be caused by noise.Check the exogenous noise level around thecamera.• This is not malfunction. (This is caused by theshape of the inner cover WV-Q153 or an innercover provided to an optional bracket.)In this case, images may also be washed outwhen "ON" is selected for "AGC".The power cannot be turnedon.The camera does not moveto the preset positions accu-rately.When the camera is pan-ning/tilting, the camera stopspanning/tilting and mechani-cal noise comes from thecamera.The camera starts panningunpredictably.When using an optional innercover, upper side of imagesare hidden (become black)when the tilt angle of thecamera is almost level.Cause/solution ReferencepagesSymptom1616–Network oper-ating instruc-tions (PDF)926Network oper-ating instruc-tions (PDF)
