Possible cause and suggested remedy

( page 5).
Check that the transmitter’s DIGITAL ANALOG control is set correctly for
the connected equipment ( page 12).
Switch the transmitter’s ATT control to “0 dB” ( page 11).
If the transmitter is connected to the headphone jack, turn up the volume
on the connected equipment ( page 10).
Turn up the volume on the headphones ( page 13).
The MUTING function is activated ( page 13).
• Check that there are no obstacles between the transmitter and the
headphones.
• Use the headphones near the transmitter.

from the plasma display ( page 11).
