preset number will be automatically tuned in.
•  When storing a station manually, the previously 
preset station is erased when a new station is stored 
in the same preset number.
 Disc operations
Caution for DualDisc playback
•  The Non-DVD side of a “DualDisc” does not comply 
with the “Compact Disc Digital Audio” standard. 
Therefore, the use of Non-DVD side of a DualDisc on 
this product may not be recommended.
General
•  This unit has been designed to reproduce 
CDs/CD Texts, and CD-Rs (Recordable)/CD-RWs 
(Rewritable) in audio CD (CD-DA), MP3/WMA (for 
KD-R306/KD-R305) formats.
•  When a disc is inserted upside down, “PLEASE” and 
“EJECT” appear alternately on the display. Press 
0 to 
eject the disc.
•  KD-R306/KD-R305: MP3 and WMA “tracks” (words 
“file” and “track” are used interchangeably) are 
recorded in “folders.”
•  KD-R306/KD-R305: While fast-forwarding or 
reversing on an MP3 or WMA disc, you can only hear 
intermittent sounds.
Playing a CD-R or CD-RW
•  Use only “finalized” CD-Rs or CD-RWs.
•  KD-R306/KD-R305: This unit can only play back files 
of the same type as those detected first if a disc 
includes both audio CD (CD-DA) files and MP3/WMA 
files.
•  This unit can play back multi-session discs; however, 
unclosed sessions will be skipped while playing.
•  Some CD-Rs or CD-RWs may not play back on this 
unit because of their disc characteristics, or for the 
following reasons:
 –  Discs are dirty or scratched.
 –  Moisture condensation has occurred on the lens 
inside the unit.
 –  The pickup lens inside the unit is dirty.

•  This unit can recognize a total of 512 files, 
255 folders, and 8 hierarchical levels.
•  This unit can play back files recorded in VBR (variable 
bit rate).
 Files recorded in VBR have a discrepancy in the 
elapsed time display, and do not show the actual 
elapsed time. In particular, this difference becomes 
noticeable after performing the search function.
•  This unit cannot play back the following files:
 –  MP3 files encoded in MP3i and MP3 PRO format.
 –  MP3 files encoded in an inappropriate format.
 –  MP3 files encoded with Layer 1/2.
 –  WMA files encoded in lossless, professional, and 
voice format.
 –  WMA files which are not based upon Windows 
Media ®  Audio.
 –  WMA files copy-protected with DRM.
 –  Files which have data such as AIFF, ATRAC3, etc.
•  The search function works but search speed is not 
constant.
Ejecting a disc
•  If the ejected disc is not removed within 15 seconds, 
it is automatically inserted into the loading slot again 
to protect it from dust. Playback starts automatically.
 Title assignment 
•  If you try to assign titles to more than 30 station 
frequencies, “NAME FULL” appears. Delete unwanted 
titles before assignment.
 Menu operations 
•  If you change the “AMP GAIN” setting from 
“HIGH POWER” to “LOW POWER” while the 
volume level is set higher than “VOLUME 30,” the 
unit automatically changes the volume level to 
“VOLUME 30.”
 –  The files on the CD-R/CD-RW are written using the 
“Packet Write” method.
 –  There are improper recording conditions (missing 
data, etc.) or media conditions (stained, scratched, 
warped, etc.).
•  CD-RWs may require a longer readout time since the 
reflectance of CD-RWs is lower than that of regular 
CDs.
•  Do not use the following CD-Rs or CD-RWs:
 –  Discs with stickers, labels, or a protective seal stuck 
to the surface.
 –  Discs on which labels can be directly printed by an 
ink jet printer.
 Using these discs under high temperature or high 
humidity may cause malfunctions or damage to the 
unit.
Playing an MP3/WMA disc (for KD-R306/
KD-R305)
•  This unit can play back MP3/WMA files with the 
extension code  or  (regardless of 
the letter case—upper/lower).
•  This unit can show the names of albums, artists 
(performer), and Tag (Version 1.0, 1.1, 2.2, 2.3, or 
2.4) for MP3 files and for WMA files.
•  This unit can display only one-byte characters. No 
other characters can be correctly displayed.
•  This unit can play back MP3/WMA files meeting the 
conditions below:
 –  Bit rate: 8 kbps — 320 kbps
 – Sampling frequency:
  48 kHz, 44.1 kHz, 32 kHz (for MPEG-1)
  24 kHz, 22.05 kHz, 16 kHz (for MPEG-2)
 –  Disc format: ISO 9660 Level 1/Level 2, Romeo, 
Joliet, Windows long file name
•  The maximum number of characters for file/folder 
names vary depending on the disc format used 
(includes 4 extension characters— or 
).
 –  ISO 9660 Level 1: up to 12 characters
 –  ISO 9660 Level 2: up to 31 characters

Symptoms Remedies/Causes
MP3/WMA playback (for KD-R306/KD-R305)
•  Disc cannot be played back. •  Use a disc with MP3/WMA tracks recorded in a format 
compliant with ISO 9660 Level 1, Level 2, Romeo, or 
Joliet.
•  Add the extension code  or  to the 
file names.
•  Noise is generated. Skip to another track or change the disc. (Do not add the 
extension code  or  to non-MP3 or 
WMA tracks.)
•  A longer readout time is required 
(“READING” keeps flashing on the display).Do not use too many hierarchical levels and folders. 
•  Tracks do not play back in the order you 
have intended them to play.The playback order is determined when the files are 
recorded.
•  The elapsed playing time is not correct. This sometimes occurs during playback. This is caused by 
how the tracks are recorded on the disc.
•  The correct characters are not displayed 
(e.g. album name).This unit can only display letters (upper case), numbers, 
and a limited number of symbols.
•  Microsoft and Windows Media are either registered trademarks or trademarks of Microsoft Corporation in the 
United States and/or other countries.

 How to clean the connectors
Frequent detachment will deteriorate the connectors.
To minimize this possibility, periodically wipe the 
connectors with a cotton swab or cloth moistened with 
alcohol, being careful not to damage the connectors.
 Moisture condensation
Moisture may condense on the lens inside the unit in 
the following cases:
•  After starting the heater in the car.
•  If it becomes very humid inside the car.
Should this occur, the unit may malfunction. In this 
case, eject the disc and leave the unit turned on for a 
few hours until the moisture has evaporated.
 How to handle discs
When removing a disc from its 
case, press down the center holder 
of the case and lift the disc out, 
holding it by the edges.
•  Always hold the disc by the edges. Do not touch its 
recording surface.
When storing a disc in its case, gently insert the 
disc around the center holder (with the printed surface 
facing up).
•  Make sure to store discs in cases after use.
Connectors
Center holder
 To keep discs clean
A dirty disc may not play correctly. 
If a disc does become dirty, wipe it with 
a soft cloth in a straight line from center 
to edge.
•  Do not use any solvents (for example, conventional 
record cleaner, spray, thinner, benzine, etc.) to clean 
discs.
 To play new discs
New discs may have some rough spots 
around the inner and outer edges. If 
such a disc is used, this unit may reject 
the disc.
To remove these rough spots, rub the edges with a 
pencil or ball-point pen, etc.
Do not use the following discs:
Single CD (8 cm disc) Warped disc
Sticker and sticker residue Stick-on label
Unusual shapeC-thru Disc (semi-
transparent disc)
Transparent or semi-
transparent parts on its 
recording area
