1. Introduction
This wireless HDMI transmitter and receiver set uses baseband technology with
a Wireless High Denition Interface (WHDI) to deliver uncompressed HD video
and audio up to 15~30 metres open eld, while maintaining superb,
wire-equivalent quality and robustness with no latency. The transmitter and
receiver both come with embedded antennas.

• PC: VGA@60/72, SVGA@60/72, XGA@60/70.
• Transmission distance between 15~30 metres open eld depending on
environment, no line of sight required.
• Real time link, less than 1 millisecond latency
• Strong 256-bit AES based encryption for security.

1. Power button: Press to turn the system ON/OFF - paired units will both turn on/
off together when this button is pressed on either unit.
2. Input button: Press to select input source (1/2/3).
3. ID button: Press to initialise ID reset procedure and re-link units if necessary*
*These sets are already paired before they leave the factory so it is usually not necessary for you to
reset them again unless the units have been unpaired.
If you need to re-link the units, press the transmitter “ID” button and hold for two seconds (the Link
LED will start to ash quickly), then press the receiver “ID” button and hold for two seconds and wait
for the system to pair. It is not necessary to press both the transmitter and receiver ID buttons at the
same time.
Press and hold the ID button for more than 10 seconds to switch to a different broadcast mode, the
two modes are unicast and multicast. Unicast mode means that the transmitter transmits to only one
paired receiver. In multicast mode, the transmitter transmits to multiple receivers. A Green power LED
indicates the unit is in Unicast mode and a red power LED indicates it is switched to multicast Mode.
The factory default is Unicast mode. We recommend that you use this mode for household use.
Note: Due to the nature of the transmission, the multicast mode has no uplink and therefore no
bi-directional communication between the Transmitter and Receiver. This results in the following
limitations:
• HDCP protected content can not be transmitted.

• CEC and EDID repeater functionalities cannot be supported.
• Multicast mode is not HDCP compliant.
4. IR sensor.
5. Power LED: The LED will illuminate when power is ON.
6. Link LED: The LED ashes quickly during initial link procedure, ashes
slowly during signal conrmation & remains solid when the link is
established.
7. Input indicator LED: The relevant LED will illuminate to indicate which
input source is currently selected and being routed to the HDMI display.

8. Troubleshooting
Situation Check Point/s
Power LED does not illuminate when power is
ON.
1. Check the right adaptor is being used - 5V/2.6 A is
the correct adaptor.
2. Check all power connectors are plugged in correctly.
3. Press the power buttons to turn on the devices
After powering up Tx & Rx, the Link LEDs are
ashing quickly / slowly without displaying a
picture.
1. Ensure your connected screen is On, and has the
correct HDMI input selected, otherwise the Receiver
unit’s link LED will ash.
2. This is normal if the devices are pairing or learning,
the LED will ash slowly when it is carrying out a signal
conrmation. Once signal lock is conrmed the LED will
remain on.
3. If the LED ashes quickly for more than
3 minutes, perform an ID reset as described on page 3
of this manual.
4. If the LED ashes slowly for more than
3 minutes, check the input selection on the transmitter
and conrm a device is connected to that input.
The Link LED remains on but no image is dis-
played or an unexpected image is displayed.
1. Check if source’s resolution is supported, the device
can support up to 1080i and 1080p 24/30, please
make sure the source is sending a supported resolu-
tion, and conrm that your display can also accept that
resolution.
2. Check that both the source and the display are HDCP
compliant.
3. Check that the TV is on the correct AV channel.
4. Check all hdmi cables have a good physical con-
nection to the Rx/Tx units and connected sources and
display.
Input LEDs do not illuminate. If the display connected to the receiver unit is not
turned on and set to the correct HDMI channel, the
input LEDs will not illuminate.
Different colours on Power LED. A Red Power LED indicates multicast mode
and a Green Power LED indicates Unicast mode.
If the Tx’s power LED is green but the Rx’s is Red. Press
and hold the Rx’s ID key for 10 seconds to change to
Unicast mode. In similar scenarios hold the ID button
down on the appropriate unit to set it to the required
broadcast mode. To change both units from one broad-
cast mode to the other carry out the procedure on both.
