I have this new transmitter that I can't seem to connect to a Lumenier DX800 DVR. The DVR has automatic channel search but does not connect to anything from the transmitter. The transmitter also does some unexpected behavior, when adjusting channels, some times two or three LEDs will light, and sometimes blink too. If I restart the tx, the LEDs settle down and there is only one channel indicated. Could I have a bad transmitter? Both of these items are new and this is the first time powering them up and trying to get the RF link working.

Thanks for any advice.
