Problem Cause & Solution PageThe sub monitor, the ACadaptor, or the charger iswarm.R This is normal. (It may feel a little warmer in summer than in winter.)→ If it feels very hot, disconnect the AC adaptor from the power outletand contact an authorised service centre.-Camera (sensor operations)Problem Cause & Solution PageMonitoring can beperformed with thecamera but sensornotifications are notreceived.R The camera (sensor detection) is turned off.→ Touch ®OffOn . 24R The camera’s [Sensor selection] setting is set to [Off] (not makedetections).→ Set [Sensor selection] to a setting other than [Off].26Sensors do not makedetections.R The motion detectionand heat sensor donot workMotion detection/heat sensorR The sensors do not operate when [Sensor selection] is set to [Off] or[External sensor only].→ Check the settings.26Motion detection does not workR Motion detection does not operate at night when [Motion detection] isset to [Day only].→ Check the settings.26R Detections may not be made when the object makes smallmovements.→ Change the [Motion detection sensitivity] setting to a highersensitivity.26R Detections are hard to make when it is dark.→ Use the heat sensor for detections or install lights to illuminate thearea around the object.-Heat sensor does not workR The heat sensor does not operate at midday when [Heat sensordetection] is set to [Night only].→ Check the settings.26R Detections may not be made in the following situations.– when reflective objects are in front of the camera and can interferewith the heat detection, such as glass– when snow is on the surface of the heat sensor– when people move towards the front of the cameraR When the outside temperature is close to the body temperature, it ishard to make detections. It is also hard to make detections whenpeople wear thick clothes.→ Change the [Heat sensor sensitivity] setting to a higher sensitivity.264711. Troubleshooting
