Warning:

If you need to operate the unit while driving, be sure to look around carefully or you may be involved in a traffic accident. Battery Products Information for Users on Disposal of Old Equipment and Batteries [European Union only] These symbols indicate that the product and the battery with this symbol should not be disposed as general household waste at its end-of-life. If you wish to dispose of this product and the battery, please do so in accordance with applicable national legislation or other rules in your country and municipality. By disposing of this product correctly, you will help to conserve natural resources and will help prevent potential negative effects on the environment and human health. Notice: The sign Pb below the symbol for batteries indicates that this battery contains lead.
Caution on volume setting:
Digital devices (CD/USB) produce very little noise compared with other sources. Lower the volume before playing these digital sources to avoid damaging the speakers by sudden increase of the output level.

For safety.

Do not raise the volume level too much, as this will block outside sounds, making driving dangerous. Stop the car before performing any complicated operations.
Temperature inside the car.
If you have parked the car for a long time in hot or cold weather, wait until the temperature in the car becomes normal before operating the unit.

Manual presetting (FM/AM)
You can preset up to 18 stations for FM and 6 stations for AM. Ex.: Storing FM station of 92.50 MHz into preset number 04.
The following features are available only for FM Radio Data System stations.
Searching for FM Radio Data System programmePTY Search
You can tune in to a station broadcasting your favorite programme by searching for a PTY code.

Select preset number 04.

The last selected PTY code appears. Select one of your favorite programme types or a PTY code.

or If a station is broadcasting a programme of the same PTY code as you have selected, that station is tuned in. Start searching for your favorite programme.
Using the standby receptions

TA Standby Reception

TA Standby Reception allows the unit to switch temporarily to Traffic Announcement (TA) from any source other than AM. The volume changes to the preset TA volume level if the current level is lower than the preset level (see page 17).
EN02-09_KD-R501_003A_f.indd 8 9/10/08 11:10:48 AM
If the TP indicator lights up, TA Standby Reception is activated. If the TP indicator flashes, TA Standby Reception is not yet activated. (This occurs when you are listening to an FM station without the Radio Data System signals required for TA Standby Reception.) To activate the reception, tune in to another station providing these signals. The TP indicator will stop flashing and remain lit. To deactivate the TA Standby Reception The TP indicator goes off.
When driving in an area where FM reception is not sufficient enough, this unit automatically tunes in to another FM Radio Data System station of the same network, possibly broadcasting the same programme with stronger signals (see the illustration below). When shipped from the factory, Network-Tracking Reception is activated. To change the Network-Tracking Reception setting, see AF-REG on page 17.

More about this unit

Turning on the power
By pressing SRC button on the unit, you can also turn on the power. If the source is ready, playback also starts.
FM Radio Data System operations
Network-Tracking Reception requires two types of Radio Data System signalsPI (Programme Identification) and AF (Alternative Frequency) to work correctly. Without receiving these data correctly, Network-Tracking Reception will not operate correctly. If a Traffic Announcement is received by TA Standby Reception, the volume level automatically changes to the preset level (TA VOL) if the current level is lower than the preset level. When Alternative Frequency Reception is activated (with AF selected), Network-Tracking Reception is also activated automatically.

Turning off the power

If you turn off the power while listening to a track, playback will start from where it had been stopped previously next time you turn on the power.

General

If you change the source while listening to a disc, playback stops. Next time you select CD as the playback source, playback will start from where it had been stopped previously. If no operation is done for about 30 seconds after pressing MENU button, the operation will be canceled.
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.

Tuner operations

During SSM search. All previously stored stations are erased and the stations are stored anew. When SSM is over, the station stored in the lowest 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.
This unit has been designed to reproduce CDs/CD Texts, and CD-Rs (Recordable)/CD-RWs (Rewritable) in audio CD (CD-DA), MP3/WMA formats. When a disc is inserted upside down, PLEASE and EJECT appear alternately on the display. Press 0 to eject the disc. MP3 and WMA tracks (words file and track are used interchangeably) are recorded in folders. While fast-forwarding or reversing on an MP3 or WMA disc, you can only hear intermittent sounds.
EN16-21_KD-R501_003A_f.indd 20 9/10/08 11:11:35 AM

Playing a CD-R or CD-RW

Use only finalized CD-Rs or CD-RWs. 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. 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

This unit can play back MP3/WMA files with the extension code <.mp3> or <.wma> (regardless of the letter caseupper/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 of MP3: 32 kbps 320 kbps Sampling frequency of MP3: 32 kHz, 44.1 kHz, 48 kHz (for MPEG-1) 16 kHz, 22.05 kHz, 24 kHz (for MPEG-2) Bit rate of WMA: 32 kbps 320 kbps Sampling frequency of WMA: 22.05 kHz, 32 kHz, 44.1 kHz, 48 kHz Disc format: ISO 9660 Level 1/Level 2, Romeo, Joliet, Windows extension. The maximum number of characters for file/folder names vary depending on the disc format used (includes 4 extension characters<.mp3> or <.wma>). ISO 9660 Level 1: up to 12 characters ISO 9660 Level 2: up to 31 characters Romeo: up to 64 characters Joliet: up to 32 characters Windows extension: up to 64 characters 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.
