Note:   
A.   If there is no signal quality shown, and the Source  & Status LED is blinking in blue, the 
transmitter is most likely out of range. You may ha ve to verify the range and adjust shorten the 
distance between the your HDTV set with the transmi tter and the receiver. (The maximum 
video transmission range is 66 feet in line of sigh t (LOS) scenarios.) < The minimum range is 6.5 
feet. > 
  
B.   If the connection or link is lost, it may be caused  by the following reasons: 
a.   The range is over the maximum transmission distance . 
b.   Either the transmitter or the receiver has been swi tched off. 
 
C.   If the SOURCE LED continues to blink in blue (slowe r than “no signal mode”) and there is no 
video displayed or the video quality suffers, this  is an indication that the video frame rate from 
the source device is not supported, or the transmis sion is out of range.
