Yamaha ATS-CU2070 Bedienungsanleitung Seite 35

Problem
All indicators go out although
the unit is turned on (it may
seem that the unit is turned
off).
The unit does not function
correctly.
The unit turns on by itself.
The TV's 3D glasses do not
work.
The unit cannot be operated
with the HOME THEATER
CONTROLLER app. (The
screen on the Bluetooth
device will not exit the app's
demo mode.)
Cause
The unit is configured so that indicators do not glow or
flash unless the unit is being operated.
The internal microcomputer is frozen, due to an external
electric shock (such as lightning or excessive static
electricity) or to a drop in the power supply voltage.
Another Bluetooth device is being operated nearby.
The unit is blocking the TV's 3D glasses transmitter.
The Bluetooth device on which the app has been installed
is not connected to the unit.
Remedy
Use the DIMMER key to select the desired brightness (p. 27).
Unplug the power cable from the AC wall outlet and plug it again.
Terminate Bluetooth connection with the unit (p. 30).
Confirm the position of the TV's 3D glasses transmitter, and
position the unit so that it does not obstruct the transmitter.
Establish a Bluetooth connection between the Bluetooth device
and the unit to use the app (p. 29).
