sunshine or inverter-type fluorescent lights. Relocate if
necessary.
• If the unit is installed in a rack or cabinet with colored-
glass doors or if the doors are closed, the remote
controller may not work reliably.
• After operating the Multi-zone function (for compatible
models only), the remote controller may have switched
to the mode for operating ZONE output audio. Check
"Multi-zone" in "Playback" in the Basic Manual to switch
the remote controller back to the mode for operating in
the main room.
Display
■ The display doesn't light
• The display may go dim while the Dimmer is working,
and may also turn off (for compatible models only).
Press Dimmer button and change the brightness level
of the display.
Others
■ Strange noises can be heard from the unit
• If you have connected another unit to the same wall
outlet as this unit, this noise may be an effect from the
other unit. If the symptoms improve by unplugging the
power cord of the other unit, use different wall outlets for
this unit and the other unit.
■ When performing AccuEQ Room Calibration, the
message "Noise Error" appears
• This can be caused by a malfunction in your speaker
unit. Check if the speakers produce normal sounds.
■ The results of AccuEQ Room Calibration give a
different distance to the speakers than the actual
distance
• There may be some discrepancies in the results
depending on the speakers you are using. If this is the
case, make the settings in "2. Speaker" - "Distance" in
the Setup menu.
Information about products with Wi-Fi/
BLUETOOTH features (for compatible models
only)
■ Radio Wave Caution
Products with Wi-Fi/BLUETOOTH use radio waves in the
2.4 GHz and 5 GHz frequency bands.
There are nations and regions where the use of particular
5 GHz bands are prohibited outdoors, so do not use these
products outside.
2.4 GHz radio waves are used by a variety of devices, as
shown in lists 1 and 2 below.
1. Devices which use a 2.4 GHz radio wave frequency
• Cordless phones
• Cordless facsimiles
• Microwave ovens
• Wireless LAN devices (IEEE802.11b/g/n)
• Wireless AV equipment
• Wireless controllers for game systems
• Microwave oven-based health aids
• Video transmitter
• Specific type of external monitor and LCD display
2. Less common devices which use a 2.4 GHz radio wave
frequency
• Anti-theft systems
• Amateur radio stations (HAM)
• Warehouse logistic management systems
• Discrimination systems for train or emergency
vehicles
If these devices and the AV receiver are used at the same
time, the audio may be undesirably stopped or disturbed
due to a radio wave interference.
Suggestions for improvement
• Switch off the devices which emit the radio wave.
• Place the interfering devices away from the AV
receiver.
• The AV receiver uses radio wave, and a third person
can receive the wave on purpose or accidentally. Do not
use the communication for important or fatal matters.
• We assume no responsibility whatsoever for any error
or damage of network environment or access device

resulting from the use of this apparatus.
Confirm with the provider or access device maker for
more information.
■ Scope of Operation
Use of the AV receiver is limited to home use.
(Transmission distances may be reduced depending on
communication environment.)
In the following locations, poor condition or inability to
receive radio waves may cause the audio to be interrupted
or stopped:
• In reinforced concrete buildings or steel framed or iron
framed buildings.
• Near large metallic furniture.
• In a crowd of people or near a building or obstacle.
• In a location exposed to the magnetic field, static
electricity or radio wave interference from radio
communication equipment using the same frequency
band (2.4 GHz) as the AV receiver, such as a 2.4 GHz
wireless LAN device (IEEE802.11b/g/n) or microwave
oven.
• If you live in a heavily populated residential area
(apartment, townhouse, etc.) and if your neighbor s
microwave oven is placed near your AV receiver, you
may experience radio wave interference. If this occurs,
move your AV receiver to a different place.
When the microwave oven is not in use, there will be no
radio wave interference.
■ Radio Wave Reflections
The radio waves received by the AV receiver include the
radio wave coming directly from the devices and waves
coming from various directions due to reflections by walls,
furniture and building (reflected waves). The reflected
waves (due to obstacles and reflecting objects) further
produce a variety of reflected waves as well as variation
in reception condition depending on locations. If the audio
cannot be received properly due to this phenomenon, try
moving the location of the wireless LAN device a little.
Also note that audio may be interrupted due to the
