The power turns off
suddenly.
When the auto power standby function is enabled, the unit
automatically turns off in any of the following situations:
- No operations have been performed for 8 hours
- BLUETOOTH or HDMI is selected as the input source,
but no audio has been input to the unit or no operations
have been performed with the unit for more than 20
minutes.
Turn on the unit again. If the auto power standby function is not
used, disable the function (p. 35).
The protection circuitry has been activated. (The
DD /
DTS indicator on the center unit flashes.)
After confirming that all connections are made properly, turn on
the unit again. If the power still turns off frequently, unplug the
power cable from the AC wall outlet and contact the nearest
authorized Yamaha dealer or service center.
The Bluetooth connection was terminated by a Bluetooth
device with the unit’s Bluetooth standby function enabled.
Disable the Bluetooth standby function (p. 33).
The power cannot be turned
on.
The protection circuitry has been activated three times
consecutively. (If you try to turn on the power in this
condition, the

flash.)
To protect the product, the power cannot be turned on. Unplug
the power cable from the AC wall outlet and contact the nearest
authorized Yamaha dealer or service center.
