Power switches off
suddenly while you
are using the AVR-
4810CI, the power
indicator will flash
in red at intervals
of approximately 2
seconds.
The protection circuit will be activated depending upon the
temperature rise in the internal parts of the unit. Please switch off
power at once, and re-apply the power after the body temperature
has fallen sufficiently.
Please re-install AVR-4810CI in a place having good ventilation.

Power switches off
suddenly while you
are using the AVR-
4810CI, the power
indicator will flash
red at intervals of
approximately 0.5
seconds.
Please use speakers which have the specified impedance.
The protection circuit has been activated because the core wires
of different speaker cables have touched each other or a core
wire has slipped out of the terminal and is touching the AVR-
4810CI’s rear panel. Unplug the power cord, then after twisting
the core wires together tightly again, or effecting termination
treatments etc, please reconnect once again.

GRemote Control UnitH
Symptom Cause / Countermeasure Page
Set does not work
properly when remote
control unit operated.
Batteries are worn. Replace with new batteries.
Operate the remote control unit within a distance of about 7 m
from the AVR-4810CI and at an angle of within 30°.
Remove the obstacle between the AVR-4810CI and the remote
control unit.
Insert the batteries in the proper direction, checking the q and
w marks.
The set’s remote control sensor is exposed to strong light (direct
sunlight, inverter type fluorescent bulb light, etc.). Move the set
to a place in which the remote control sensor will not be exposed
to strong light.
Make sure the remote control IDs of the main unit and remote
control unit match. If the IDs do not match, “AVAMP z” (z is
the main unit’s remote control ID) appears on the AVR-4810CI
display when the remote control unit is operated.
Set the remote control unit’s function button properly.
