To Adjust the Audio Input Level
If the sound from the Digital Audio Player connected to the LINE IN jack is too loud or too 
quiet, you can change the audio input level through the LINE IN jack (without changing 
the volume level).

Press and hold for more than 2 seconds while “LINE” is selected as the source.

You can select one of three levels as follows:

Basic and Common Operations (see page 3)
•  Pressing one of the source buttons also turns on the System 

and starts playing back.

Playing Back a Disc/USB Mass Storage Class Device 
(see page 4)
•  This System cannot play “packet write” discs.
•  For MP3/WMA playback...
  – In this manual, “file” and “track” are interchangeably used 

for MP3/WMA operations.

  – This System can show the Tag data (Version 1).
  – MP3/WMA discs are required a longer readout time than 

regular CDs. (It depends on the complexity of the group/
file configuration.)

  – Some MP3/WMA files cannot be played back and will be 

skipped. This result from their recording processes and 
conditions.

  – When making MP3/WMA discs, use ISO 9660 Level 1 or 

Level 2 for the disc format.

  – This System can play back MP3/WMA files with the 

extension code <.mp3> or <.wma> (regardless of the 
letter case—upper/lower).

  – It is recommended that you make each MP3/WMA file at a 

sampling rate of 44.1 kHz and at bit rate of 128 kbps. This 
System cannot play back files made at bit rate of less than 
64 kbps.

  – Playback order of MP3/WMA tracks may be different from 

the one you have intended while recording. If a folder 
does not include MP3/WMA tracks, they are ignored.

•  For the USB mass storage class device playback...
  – When connecting a USB mass storage class device, also 

refer to its manual.

  – Connect one USB mass storage class device to the System 

at a time. Do not use a USB hub.

  – This System is compatible with USB 2.0 Full Speed.
  – You can play back MP3/WMA files in a USB mass storage 

class device (maximum data transfer rate: 2 Mbps).

  – You cannot play back a file larger than 2 Gigabyte.
  – This System cannot recognize a USB mass storage class 

device whose rating is other than 5 V and does not exceed 
500 mA.

  – This System may not play back some USB mass storage 

class devices and does not support DRM (Digital Rights 
Management).

•  This System can recognize up to 511 tracks in a disc/USB 

mass storage class device. Also, the System can recognize 
up to 150 tracks per group and up to 99 groups in a disc/
USB mass storage class device (for MP3/WMA).

  – Playable files which do not belong to any groups are 

handled as Group 1.

Setting the Clock and Daily Timer (see page 5)
•  You can set the clock and Daily Timer while the Save mode 

is turned on. While setting the clock or Daily Timer, the 
display is turning on.

•  The clock may gain or lose 1 to 2 minutes per month. If this 

happens, readjust the clock.

•  When you unplug the AC power cord or if a power failure 

occurs, the clock and the timer will be canceled. You need 
to set the clock first, then the timer again.

Timer Priority:
•  If you set the Sleep Timer after Daily Timer starts playing the 

selected source, Daily Timer is canceled.

Listening to Digital Audio Player (see page 6)
•  When the sound signal from the Digital Audio Player is too 

weak, QP Link may not function correctly.

  In this case, turn up the volume of the Digital Audio Player 

so that the System can detect the sound signal properly.

•  Changing from “LINE” to another source while QP Link works 

will deactivate QP Link temporarily.

  In this case, the following reactivate QP Link:
  – Pressing and holding QP LINK on the remote control.
  – When no sound signal comes from the LINE IN jack for 

about 30 seconds after the System is turned off.

•  If you press 

 button to turn the System off or if preset 

Timer turns the System off while QP Link works, the System 
deactivates QP Link temporarily. In such cases, the following 
reactivate QP Link:

  – When no sound signal comes from the LINE IN jack for 

about 30 seconds after the System is turned off.

  – When you turn on the power again.
