Cause
• The protection circuit will be
activated depending upon the
temperature rise in the internal
parts of the unit.
• Use speakers having impedance
less than that specified.
• If speaker cable core wires touch
each other or the core wires
become disconnected from their
terminals, the protection circuit
will be activated in the event of
core wires coming into contact
with the AVR-1610 rear panel.
• The AVR-161O amplifier circuit
has failed.
• Batteries are worn.
• You are operating outside of the
specified range.
• Obstacle between main unit and
remote control unit.
• The batteries are not inserted in
the proper direction, as indicated
by the polarity marks in the
battery compartment.
• The set's remote control sensor
is exposed to strong light (direct
sunlight, inverter type fluorescent
bulb light, etc.!.
• The device selection switch is
not set to the proper position.
• Perform the remote control unit
device mode setting operation.
Countermeasure
• Please switch off power at once,
and re-apply the power after
the body temperature has fallen
sufficiently.
• Please re-install AVR-1610 in a
place having good ventilation.
• Please use speakers which have
the specified impedance.
• Unplug the power cord, then
after twisting the core wires
together tightly again, or effecting
termination treatments etc,
please reconnect once again.
• Switch off the power and please
contact the DENON service
adviser.
• Replace with new batteries.
• Operate within the specified
range.
• Remove the obstacle.
• Insert the batteries in the
proper direction, following the
polarity marks in the battery
compartment.
• Move the set to a place in which
the remote control sensor will
not be exposed to strong light.
• Set the device selection switch
to the proper position, according
to the purpose for operating the
switch.
• Before operating the remote
control unit, set the device mode
for the device to be operated.
