Safety:
1. Do not open or repair the device without professional assistance to avoid electrical
shock.
2. Do not expose this unit to water, moisture or any liquid.
3. Position the unit in a well ventilated area to prevent the unit from overheating.
4. Only use the supplied 5VDC, 1A power adaptor. If you use any third party power
supplies, ensure the voltage is the same to prevent the unit from damage.
Solution
Ensure the HDMI input and output is correct. The audio extractor
mode should have the source device in the HDMI input and the TV in
the HDMI Output. The ARC mode should only have the TV connected
to the HDMI output.
Check to see if your source device and TV's/monitors are all switched
on .
Change the HDCP switch to the opposite side. Old devices using
HDMI versions such as 1.4 require the HDCP 1.4 version to be select-
ed. Newer devices using HDMI 2.0 should have HDCP 2.2 selected. If
using HDCP 2.2 then your HDMI cables should be HDMI 2.0 or above.
Check to see if the mains power adaptor is connected properly and
switched on.
Reconnect the HDMI cables on both the HDMI input and output de-
pending on which mode you're in.
If you're using the 3.5mm audio output; it can only support 2.1
channel sound so if your device is 5.1 then it may not work.
Ensure the coaxial and TOSLINK outputs are not being used at the
same time. This device can only support one of the coax and TOS-
LINK outputs at a time.
Check the audio is up and the power is turned on for your external
speakers, headphones or sound bar.
When in ARC mode, check the HDMI is connected to the HDMI ARC
port of the TV.
Ensure all the cables are HDMI 2.0 if using HDCP 2.2 on newer devic-
es.
Reconnect the HDMI cables on both the transmitter and receiver and
make sure the HDMI cables are functioning correctly.
