④ Link LED: When the system is in search mode the④blue LED will flash repeatedly, and when it is in
signal linking mode it will slowly flash. When the LED⑥is on and there is no flashing it means the system isready and audio or video can be sent.
①⑤ ID: Press this button with the receivers “ID” button
for two seconds to connect the systems. Before
they left the factory the systems were alreadyconnected so there is no need for the user toreset the connection unless the systems cannot②
link up properly. Press the ID button for more thanten seconds to switch between Broadcast and③
Unicast mode. When the green LED is on it means
the system is in Unicast mode and when the Red⑤
LED is lit the system is in Broadcast mode. The⑥
default mode for this system is Unicast and it isrecommended to use this for home use. It is notnecessary to press both the transmitter and receiver
buttons at the same time.
Note: Due to the nature of Broadcast mode, which
has no uplink, there can be no communication
between Transmitter and Receiver, the result is thefollowing:• HDCP protected content should not betransmitted.
• CEC and EDID repeater functions cannot besupported.
• Broadcast mode is not HDCP compliant.
• Only supports single transmitter link with multiplereceivers.
⑥ Power: The LED will illuminate when power is on.

11. Troubleshooting
Issue
Power LED does not lightup when power is on.

Recommendation
1. Check if the right adaptor is used.
Transmitter: 5V/6A and Receiver: 5V/2.6A
2. Check that all power connectors are plugged incorrectly.
3. Push the power buttons to turn on the devices.

After powering on Tx &Rx boxes the links LED isﬂashing quickly/slowly
without an image being
displayed.

1. This is normal when the devices are in searchor signal linking mode. Once a link has been
established and the signal is reliable it will nolonger ﬂash.
2. If the LED has been ﬂashing repeatedly for morethan 3mins it is recommended to re-connect
the devices by pressing the “ID” button for twoseconds.
3. If the LED has been slowly ﬂashing for morethan 3mins make sure the input cable of thetransmitter is properly connected.

The link LED is turnedon and consistent,
but without an image
displayed or an
unexpected image.

1. Check if the source is compatible with thedevice. The device supports up to 1080i, so
please be sure that the source is sending acompatible signal for the display and the display
can also accept that signal.
2. Check if both source and the display are HDCP/
CEC complaint.
3. Check if TV is in HDMI mode.
4. Check if both source and display areconnected stably.

Input LED does not turnon.

1. When linking for the first time, if the output
display is not properly connected, the red LED
will not turn on; therefore check if the HDMI
output is connected.

Different color on PowerLED.

1. Red Power LED means system is in Broadcast
mode and Green Power LED means Unicast
mode.
If Tx has green LED but Rx has red LED, press Rx’s
ID button for ten seconds. But when Broadcast
mode is demanded press Tx’s ID for ten seconds
to switch to Broadcast mode.
