Operating instructions
Symptom Remedy
Noise is output when scanning a DTS CD. This is not a malfunction of the receiver. The scan function of your 
player alters the digital information, making it unreadable, result-
ing in noise being output. Lower the volume when scanning.
When playing a DTS format LD there is 
audible noise on the soundtrack.
Make sure that the input signal type is set to DIGITAL (see Choos-
ing the input signal on page 34 ).
Can’t record audio. You can only make a digital recording from a digital source, and an 
analog recording from an analog source.
For digital sources, make sure that what you’re recording isn’t 
copy protected.
Subwoofer output is very low. To route more signal to the subwoofer, set it to PLUS or set the 
front speakers to SMALL (see Speaker Setting on page 62 ).
Everything seems to be set up correctly, 
but the playback sound is odd.
The speakers may be out of phase. Check that the positive/negative 
speaker terminals on the receiver are matched with the corre-
sponding terminals on the speakers (see Connecting the speakers 
on page 12 ).
The Phase Control feature doesn’t seem 
to have an audible effect.
If applicable, check that the lowpass filter switch on your sub-
woofer is off, or the lowpass cutoff is set to the highest frequency 
setting. If there is a PHASE setting on your subwoofer, set it to 0º 
(or depending on the subwoofer, the setting where you think it has 
the best overall effect on the sound).
Make sure the speaker distance setting is correct for all speakers 
(see Speaker Distance on page 63 ).
Noise or hum can be heard even when 
there is no sound being input.
Check that personal computers or other digital components con-
nected to the same power source are not causing interference.
Can’t select some Input functions by the 
INPUT SELECTOR on the front panel or 
the INPUT SELECT button on the remote 
control.
Check the Input Skip settings in the Input Setup menu (see The 
Input Setup menu on page 24 ).
Check the HDMI Input assignment in the Input Setup menu then 
try OFF (see The Input Setup menu on page 24 ).
There seems to be a time lag between the 
speakers and the output of the subwoofer.
See Automatically conducting optimum sound tuning (Full Auto 
MCACC) on page 23 to set up your system again using MCACC 
(this will automatically compensate for a delay in the subwoofer 
output).
The maximum volume available (shown in 
the front panel display) is lower than the 
+12dB maximum.
Check that the Volume Limit is set to OFF (see Volume Setup on 
page 66 ).
The channel level setting may be over 0.0dB.
The volume level drops automatically. The temperature within the unit has exceeded the allowable value. 
Try moving the unit for better ventilation (see Installing the receiver 
on page 5 ).

Symptom Remedy
The Bluetooth  wireless technology device 
cannot be connected or operated. Sound 
from the Bluetooth wireless technology 
device is not emitted or the sound is 
interrupted.
Check that no object that emits electromagnetic waves in the 2.4 
GHz band (microwave oven, wireless LAN device or Bluetooth 
wireless technology apparatus) is near the unit. If such an object 
is near the unit, set the unit far from it. Or, stop using the object 
emitting the electromagnetic waves.
Check that the Bluetooth wireless technology device is not too 
far from the unit and that obstructions are not set between the 
Bluetooth wireless technology device and the unit. Set the Blue-
tooth wireless technology device and the unit so that the distance 
between them is less than about 10 m and no obstructions exist 
between them.
Check that the Bluetooth ADAPTER and the ADAPTER PORT of the 
unit are correctly connected.
The Bluetooth wireless technology device may not be set to the 
communication mode supporting the Bluetooth wireless technol-
ogy. Check the setting of the Bluetooth wireless technology device.
Check that pairing is correct. The pairing setting was deleted from 
this unit or the Bluetooth wireless technology device. Reset the 
pairing.
Check that the profile is correct. Use a Bluetooth wireless technol-
ogy device that supports A2DP profile and AVRCP profile.
Video
Symptom Remedy
No image is output when an input is 
selected.
Check the video connections of the source component.
For HDMI, or when digital video conversion is set to OFF and a TV 
and another component are connected with different cords (in 
Setting the Video options on page 46 ), you must connect your TV 
to this receiver using the same type of video cable as you used to 
connect your video component.
Make sure the input assignment is correct for components con-
nected using component video or HDMI cables (see The Input 
Setup menu on page 24 ).
Check the video output settings of the source component.
Check that the video input you selected on your TV is correct.
Some components (such as video game units) have resolutions 
that may not be converted. If adjusting this receiver’s Resolu-
tion setting (in Setting the Video options on page 46 ) and/or the 
resolution settings on your component or display doesn’t work, try 
switching Digital Video Conversion (in Setting the Video options on 
page 46 ) to OFF.
