You have intermittent loss of
audio or video. Check the cable connections and reconnect them.
Loss of audio or video can be caused by using overly rigid or thick cables. Make sure
the cables are flexible enough for long term use. If mounting the product to a wall, we
recommend using cables with 90 degree connectors.
You see small particles when
you look closely at the edge of
the frame of the product. This is part of the product’s design and is not a defect.
