Specifications
No 
communicatio
n between the 
sender and 
receiver
• Make sure that the AC adapter is connected to the sender and the power cord is 
connected to the receiver.
• Once the power-on buttons have been held to turn on both sender and receiver 
and both units are in joining mode, the power-on indicators should blink quickly.
• If the power-on indicators on both units are solid on, then a communication link 
has been successfully established between the units. If the power indicators on 
both the units are blinking at a slower rate, press and hold the   buttons on 
either sender or receiver for three seconds. This will put the unit into joining mode 
for about 30 seconds. During this time, press the   button on the other unit for 
three seconds, so that it will also enter joining mode. The system proceeds with 
the connection process between the sender and receiver. During the joining 
mode, the power indicators on both sender and receiver blink at a faster rate. 
When an active link is established between the sender and receiver, the power-on 
indicators on both units are solid on and do not flash.
Note: Try pressing the   buttons again if the power indicators are blinking at a slower 
rate after blinking fast for 30 seconds.
No response 
when you press 
any button
• Try disconnecting the main power to reset the device.
Connecting a 
source device
• If your network is already full with transmitters when joining is attempted, the 
Source LED will blink three times and then turn off. Remove (power down) a 
transmitting device and try again.
Connecting a 
device
• When you try to join a device to a network that has too many nodes, the device 
will stay in joining mode until it times out (30 second timeout). Upon timeout the 
unit should be on and will flash the power ring LED in a slow blink indicating it is 
not connected to the network.
When trying to 
change the 
source on a 
Rocketfish unit 
the Power LED 
flashes 5 times.
• Your RF-RBKIT sender is in four channel lock mode. By design, these channels are 
not available for access by other receivers as they form the rears/surrounds of your 
Home Theater system. If you do wish to use them, then you should remove the 
four channel lock mode by moving the switch on the back of the sender to disable 
four channel lock mode. Both sources will then be available for all receivers.
