  Receiver

1.Channel Indicator LED is not on::

Please check if the power adaptor of the receiver is well connected, and check if the main power is on.

2.No images or imanges are not clear.:

a.

Please check power has been switched;;

b.

Please check if the distance is too long between camera and receiver, or if there are any electromagnetism obstruction around (e.g. steel construction will counteract transmitting signals.Or 2.4Ghz wireless router)

c.

Please check whether the frequency of the transmitter is the same with the receiver’s or not. (Two cameras with the same frequency can not work properly within effective distance, thus interference will be caused)

d.

Please confirm the receiver antenna has been fixed tightly.

e.

Please keep far away from big copper or iron electromagnetism obstruction. High-power transmitter in the same frequency and car broadcasting station may also cause interference.
