■ Listening Modes
0 To enjoy digital surround playback, such as Dolby Digital,
the audio signals need to pass through a connection via
HDMI cable, digital coaxial cable or digital optical cable.
Audio output should be set to bitstream output on the
connected Blu-ray Disc player or other device.
0 Press on the remote controller several times to switch
the display of this unit to check the input format.
Check the following if the above does not fix the problem:
About DTS signals
0 With media that switches suddenly from DTS to PCM,
PCM playback may not start immediately. In such cases,
you should stop your player for about 3 seconds and then
resume playback.
0 With some CD and LD players, you will not be able to
playback DTS material properly even though your player
is connected to a digital input on the unit. This is usually
because the DTS bitstream has been processed (e.g.,
output level, sampling rate, or frequency response
changed) and the unit does not recognize it as a genuine
DTS signal. In such cases, you may hear noise.
0 Playing DTS program material, using the pause, fast
forward, or fast reverse function on your player may
produce a short audible noise. This is not a malfunction.
■ Video
0 Confirm that the connection between the output jack on
the device and the input jack on this unit is correct.
0 Make sure that none of the connecting cables are bent,
twisted, or damaged.
0 When the TV image is blurry or unclear, power code or
connection cables of the unit may have interfered. In that
case, keep distance between TV antenna cable and
cables of the unit.
0 Make sure the switching of input screens is proper at the

displayed. In this case, the TV does not support the
resolution of the video input from the player. Change the

0 Reliable operation with an HDMI-to-DVI adapter is not
guaranteed. In addition, video signals from a PC are not
supported.
Images flicker
