Problems & Solutions

* The indicator of the Channel display window is not lighting. Check whether the socket of the power Adapter works well or not, and make sure the power switch is turning on
* The Receiver cannot receive picture or the picture-received flashes
* Please check whether the Wireless Camera have already put through the power
* Whether the distance between Wireless Camera and Receiver is too far or whether there is Electromagnetic shielding Barrier between Wireless Camera and Receiver (eg: Building of steel structure will make much hindrance to transmitting signal)
* In the Range of Receiving, Don't make two Wireless Cameras with the same Frequency work at the same time, otherwise they will cause interfering
* When the transmitting Cameras of different Frequency work at the same time, the distance between the Cameras should be kept about or over 2 meters, otherwise receiving will be interfered
* If there are high-power transmission signals with the same Frequency and Car-mounted Radio working around, they will cause
