devices or connection of the
speaker cables is faulty.
• Check the connections.

Power turns off
suddenly and
power indicator
flashes red.
• Protection circuit activated due
to rise of internal temperature.
• Core wires of two speakers are
touching each other or a core
wire is sticking out of the terminal
and touching the set’s rear panel,
activating the protection circuit.
• Speakers with an impedance
other than specified are being
used.
• Set is damaged.
• Turn off the power, wait for the
set to fully cool down, then turn
the power back on.
• Place the set in a well-ventilated
place.
• First unplug the power cord,
then twist the core wires tightly
or terminate the speaker cables,
then reconnect.
• Use speakers with the specified
impedance.
• Turn off the power and contact a
DENON service center.
