Yamaha R-N803 Owner's Manual

If a warning message is displayed after the measurement, you can still save the measurement results.
However, we recommend you perform YPAO again in order to use this unit with the optimal speaker settings. 

• If more than one warning is detected, use the cursor keys (

B

 / 

C

) to check another warning message.

• To return to the previous state after checking the warning message, press the cursor key (

D

)).

A speaker cable may be connected with the 
reverse polarity (+/-).

check the cable connections (+/–) of the 
speakers.
If the speaker is connected incorrectly, turn off 
this unit and then reconnect the speaker cable.
Depending on the type of speakers or room 
environment, this message may appear even if 
the speakers are connected correctly. In this 
case, you can ignore the message. 

A speaker is placed more than 24 m (80 ft) from 
the listening position

Move the speaker within 24m (80 ft) of the 
listening position.

There are significant volume differences 
between the speakers.

Check the usage environment and cable 
connections (+/–) of each speaker, and the 
volume of the subwoofer. We recommend using 
the same speakers or speakers with 
specifications that are as similar as possible.
