Power and system
Problem
Cause
Remedy
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. 27).
The protection circuitry has been activated. (The
DD /
DTS indicator 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. 25).
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
DD / DTS indicator will 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.
All indicators go out although
the unit is turned on (it may
seem that the unit is turned
off).
The unit is configured so that indicators do not glow or
flash unless the unit is being operated.
Use the DIMMER key to select the desired brightness (p. 21).
