Cause
• The power plug is disconnected.
• The protection circuit may have been
activated.
• Something is obstructing the rear panel
ventilation device.
• The speaker wires are frayed or sticking out
of the jack, and are touching the back of the
receiver or another set of wires.
• The receiver has a serious problem.
• The protection circuit has been activated
because the lowest actual impedance of the
speakers (as opposed to the speakers rated
impedance) is dangerously low.
• Static electricity caused by dry air.
• The receiver has a serious problem.
• Something is obstructing the fan.
• The fan is malfunctioning.
• The internal temperature of the unit has
become too high.
• The thermistor (temperature sensor) is
broken.
Remedy
• Connect the power plug to the wall outlet.
• Disconnect the power plug from the outlet, and insert
again.
• Unplug the receiver from the wall and call a Pioneer
authorized independent service company.
• Reinsert the speaker wires, making sure there are no
stray strands of wire and that they are inserted fully.
• Unplug the receiver from the wall and call a Pioneer
authorized independent service company.
• Turn down the volume.
• When it's convenient, go to Acoustic Calibration EQ on
page 88 and lower the 63 Hz and 125 Hz equalizer levels
using the manual setting.
• Turning the digital safety feature on may allow you to
turn up the volume a little more. To switch between
SAFETY ON and SAFETY OFF, put the receiver into
STANDBY/ON button while
standby, then press the
holding down the MULTI JOG CONTROL SET UP button
on the front panel.
• Switch the unit off, then on again.
• Disconnect the power plug from the outlet, and insert
again.
• After about a minute (you won't be able to switch the
unit on during this time), switch the receiver back on. If
the message persists, call a Pioneer authorized
independent service company.
• Remove the obstruction and try switching the receiver
back on. If the fan is still not working, or you can't remove
the object, unplug the receiver from the wall and call a
Pioneer authorized independent service company.
• Unplug the receiver from the wall and call a Pioneer
authorized independent service company.
• After allowing the unit to cool down in a well-ventilated
place, try switching the receiver back on. Make sure you
follow the guidelines for improving heat dispersal in the
safety precautions on pages 2–3.
• Turn the receiver off, unplug from wall and call a Pioneer
authorized independent service company to look at the
problem.
