are using the AVR-
4310CI, 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-4310CI in a place having good ventilation.

Power switches off 
suddenly while you 
are using the AVR-
4310CI, 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-
4310CI’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.

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-4310CI and at an angle of within 30°.
Remove the obstacle between the AVR-4310CI 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.
Set the remote control unit’s function button properly.
