DMP Audio Playback
Q. Why would audio playback be silent when my signal cable type is HDMI?
A.
Make sure that your DMP has attributed an authentically HDMI-standard resolution value — such as
“HDMI_1080p60” — to your presentation system (CSCsk29797). The HDMI standard does not
support audio playback through any system whose settings ignore or contradoct HDMI standards.
Thus, you cannot use HDMI to play audio through a presentation system whose resolution setting
is, for example, “VESA_1360x768x60.”

DMP Remote Control
Q. How can I improve the effectiveness of a DMP remote control?
A.
Compensate for known factors.
DMP-attached Touchscreens
Q. What can cause a properly calibrated touchscreen to operate as if it is not calibrated?
A.
If this happens to you, unplug the serial cable (or USB cable) that connects this touchscreen to
your DMP. Then, plug that cable back in again.

Your DMP is equipped with an infrared (IR) sensor that receives, recognizes, and
reacts to the signals from a DMP remote control.
reacts to the signals from a DMP remote control.
However, the way that you mount your DMP can limit how well it responds to these
signals. For example, the mounting method might block the IR sensor. This in turn
might cause you to attach an IR extension cable to your DMP, as a workaround.

might cause you to attach an IR extension cable to your DMP, as a workaround.
But even when you mount the receptor from this extension where it is not
obstructed — and even though this method improves the reception of IR signals that
are blocked otherwise — IR extension cables are not perfect. The physics that
underlie their design ensure that these cables always have some signal loss,

Furthermore, greater cable length contributes greater signal loss. Thus, the field
(angle) of transmission becomes narrower for a remote control and the range
(distance) becomes shorter in direct proportion to the length of the IR extension cable.

Prevent sunlight from shining directly on your DMP’s IR sensor. And take further
steps as needed to stop halogen bulbs from shining at the sensor.
