Problems & Solutions
1:There are screaming voice if the distance between the camera and monitor is near
Answer: This phenomenon is caused by the acoustical feedback,the audio signal of microphone is gleaned by
receiver’s speaker and then the microphone pick the signal again and transmit them together with camera’s
voice,the receiver will have louder voice than before.Therefore,it can cause the formation of self-excited
oscillation round and round ,and result in the screaming voice.However,you can solve this problem by turn
down the speaker volume or insert the headset into the receiver.
2:No response
Answer:Check whether the power adapter is connected well,check whether the battery is installed well.Please
install the battery in correct direction.And check whether receiver power button is ON position
3：LCD can`t display when power on
Answer:Please Check whether the AV line and not connected to insert the TV，whether press the POWER
button is short in auto sleep mode,then press the POWER button in short time to see if the display work or not.
