Problem Possible Solutions
The remote
control does not
work.
• Verify that the remote control is in “Cable”
mode.
• Verify that there are no obstructions between
the remote control and the DCH receiver. Aim
the remote control directly at the DCH receiver
front panel, not the TV or VCR.
• If using an external IR senor connected to the
EXT IR input on the rear panel, ensure the cable
is properly connected to the rear panel input and
that there is a clear line-of-sight from the remote
to the sensor.
• The angle between the remote control and the
DCH receiver may be too large. Stand in front of
the DCH receiver and not too far to either side.
• Press and release operation keys one at a time,
firmly and deliberately.
• Check the batteries in the remote control. Install
new batteries if needed.
There is no
audio when
viewing cable
channels.
• Verify that the Mute button on the remote
control has not been pressed. Press mute on
the remote control to restore sound.
• If the DCH receiver audio output is connected to
the TV, verify that the Mute button on the TV has
not been pressed.
• If the DCH receiver audio output is connected to
a home theater receiver, verify that the receiver
is set to the appropriate input source and the
Mute button on the receiver has not been
pressed.
• Verify that you have the correct cables for the
audio connections.
• Verify that the audio cables are firmly connected
between the DCH receiver and the audio
playback device (TV, receiver, DVD player, etc.).
