 Multiple Applications
The Wireless Cable TVs Systems are designed to be used in applications where more 
than one system is needed.  There are two different applications and a solution for each.
1.    
If you have two or more locations where a wireless TV solution is needed and those 
locations are not used simultaneously, then all you need is one complete system and 
multiple receivers.  All receivers will display the same channel.
2.    If you have two or more locations where a wireless TV solution is needed and those 
locations are used simultaneously, then you will need complete systems to keep all wireless 
systems completely independent. 
Note:  Each system comes with 4 RF channels.  When using multiple systems for 
independent applications, the systems must be on different RF channels and  you must turn 
“Synchronization” OFF  in the on screen menu.

Troubleshooting
Why does my remote control not change the channels?
1.  The Wireless Cable TVs has built in synchronization. If the TX and the RX have not synchronized, the remote control will not 
work the Channel function. And pls do above firstly
  a) Pull up flexible antenna
  b)  Used RF splitter. Don't connected to " RF out " ( Because some cable supplier will carr\
ier electrical power inside. This is 
another type interfere for us.)
To test for synchronization, set the RF channel on the transmitter and re\
ceiver to channel 4. If you connections are correct, you should 
see a TV picture
Once you have a picture, point the remote control at the receiver and press the RF button. The RF channel should change to RF 1 and 
the Picture should follow. If you lose the picture, they are not synchronized and the remote will not work.
Put the receiver back on RF channel 4 so that you see your picture. 
Now, go to the transmitter room and move the transmitter one way or the other. By moving the tranmitter, this allows the receiver try 
and synchronize. You may have to change the position of the transmitter several times to gain synchronization. Once you find the right 
position for the transmitter, leave it in that position.
If you still have problems getting the remote control to work, try moving the transmitter to a diferent cable drop if available. 
Why am I not getting a picture?
1. Make sure both units are on the same RF Channel (1,2,3 or 4)
2. Make sure that if you are using the system in TV mode, that the top light on both units are ON
3. If you connected the remote TV using coaxial cable, make sure your TV is ON and is on Channel 3
4. Make sure you follow the instructions on page 8 of the owners manual when connecting your transmitter to your incoming cable..
