29Symptom Cause/solution ReferencepagesThe camera startspanning unpredict-ably.• This may be caused by noise.Check the exogenous noise level around the camera. 11• The protection circuit against high temperature may function.When the digital flip (function to turn the screen upside-down when tilting exceeds a certain angle) continues fora given time in high temperature, the system releasesthe digital flip and operates panning and tilting automati-cally to return the screen to the original position.• The position refresh may be done automatically toimprove the positional accuracy of PAN, TILT and ZOOMwhen turned on in low temperature, which is not a failure.−The LINK indicatordoes not light inorange even whenthe Ethernet cable isconnected to thecamera.• Is the Ethernet cable connected appropriately?Connect the Ethernet cable appropriately.• Is the hub or router connected to the camera operatingappropriately?Check if the hub or router in use is operating appropriately.• Isn’t the Ethernet cable connected to the camera broken?Replace the cable with another one.18Indicators neverlights up.• Is “Off” selected for “Indicator” on the “Basic” page?Select “On” or “On(Access)” for the indicator setting.
