Message Meaning Solution
EEP ERROR An error has occurred in the backup memory data. Contact your point of purchase or Sony service
representative.
PLL ERROR An error occurred in the PLL synthesizer circuit. Restart the unit. If the message persists, contact your
point of purchase or Sony service representative.
NO TONE Audio signal output has been muted, because a tone
signal different from the compander mode configured
on the tuner was received.
Configure the appropriate compander mode based on
the transmitters you are using “Setting the compander
mode (COMPANDER)” (page 25).
When operating in conjunction with UWP-D series
transmitters (UTX-B40, UTX-M40, etc.), set the tuner
and the transmitters to the same compander mode.
