TONE

T OFF

a)

An error occurred in

backup memory data.

The PLL synthesized

circuit is in trouble.

The operating voltage

exceeds the allowable

value.

As no tone signal is

available or a tone signal

other than 32.768 kHz is

being received, the audio

signal output is being

muted.

The tuner is set in T OFF

mode.

Contact your Sony dealer.

Set the tuner to the T OFF

mode (see page 13) to

output the audio signal.

For details, see “Selecting

and Releasing the T (Tone

Squelch) OFF  Mode" on

page 12.

on the WRR-855A. On the WRR-855B, the message appears
after the version number of your tuner.
Subsequently, the tuner goes to the normal display status.
