• HDMI cables must be 5 meters or less in length.
• If watching 3D source, make sure the display is 3D enabled.
Video and Audio do not match.
• Check that the proper video source is selected for each input.
• Check that the group delay (lip-synch) setting is not mis-adjusted.
Clicking or popping sounds when switching inputs
• The unit uses relay switching to preserve maximum sound quality. The
mechanical clicking of the relays is normal.
• Switching between HDMI sources may cause delays as HDMI two way
communications "handshake" must be established between the source
and display. The time required for the handshake varies depending
on the attached equipment.
Controls do not operate
• Make sure that fresh batteries are installed in the remote.
• Make sure that the IR sensor on the front panel is not blocked. Aim the
remote control at the sensor.
• Make sure the sensor is not receiving strong IR light (sunlight, halogen
lighting, etc.).
• Unplug the unit from the AC outlet, wait 30 seconds, and plug it
back to reset.
• Confirm the IR Codeset set in the remote control and RAP-1580 are
matched to either Codeset 1 or Codeset 2.
