On handling compact discs (CD/CD-R/CD-RW) • Do not touch the surface. • Do not expose the disc to direct sunlight. • Do not affix stickers or labels. • Clean the disc when it is dusty. • Make sure that the disc is smooth and flat. • Do not use commercially available disc accessories. Do not leave the disc in the car or the unit for a long time. Never expose the disc to direct sunlight. Heat and humidity may damage the disc and you may not be able to play it again. Using DVD-Rs/DVD-RWs/DVD+Rs/DVD+RWs • This unit is compatible with discs recorded in the standard DVD-Video format. • Note that discs not finalized (processed to enable to play on playback-only DVD players) cannot be played on this DVD player. • Some discs may not play back, depending on the recording device and disc format. • Discs or files utilising copy protection, may not be playable. Some recording systems may not properly format copied files to enable proper playback. • In the following cases, the disc may not play on this unit: discs recorded by certain DVD recorders, certain irregular discs, flawed discs, dirty discs, when the pickup lens of this DVD player is dirty, or when moisture condensation has occurred inside the unit. • Be sure to follow all cautions included with your DVD-Rs/ DVD-RWs/DVD+Rs/DVD+RWs discs. • Do not put stickers, seals, or tape on the label side of DVD-Rs/ DVD-RWs/DVD+Rs/DVD+RWs. • Compared to the regular discs, DVD-Rs/DVD-RWs/DVD+Rs/ DVD+RWs are more affected by heat, moisture, and direct sunlight. If left in a car, etc., damage may occur and it might not play on this unit. • The operable temperature range for disc playback is as follows: DVD-R/DVD-RW: ­25 to +70°C DVD+R/DVD+RW: +5 to +55°C About the Supported Formats About MP3/WMA/AAC/FLAC CAUTION Except for private use, duplicating audio data (including MP3/WMA/AAC/FLAC data) or distributing, transferring, or copying it, whether for free or for a fee, without permission of the copyright holder is strictly prohibited by the Copyright Act and by international treaty. What is MP3? MP3, whose official name is "MPEG Audio Layer 3," is a compression standard prescribed by the ISO, the International Standardisation Organisation and MPEG which is a joint activity institution of the IEC. MP3 files contain compressed audio data. MP3 encoding is capable of compressing audio data at extremely high ratios, reducing the size of music files to as much as one-tenth their original size. This is achieved while still maintaining near CD quality. The MP3 format realizes such high compression ratios by eliminating the sounds that are either inaudible to the human ear or masked by other sounds. What is WMA? WMA, or "Windows Media™ Audio," is compressed audio data. WMA is similar to MP3 audio data. What is AAC? AAC is the abbreviation for "Advanced Audio Coding," and is a basic format of audio compression used by MPEG2 or MPEG4. What is FLAC? FLAC (Free Lossless Audio Codec) is an audio file codec for lossless compression, developed and offered as open source software. Codecs with lossy compression forms, such as MP3 and AAC, reduce part of the data to improve compression efficiency. However, FLAC can reconstruct compressed data to be an identical copy of the original data by performing lossless compression. The compression ratio of FLAC is about 50%. Method for creating MP3/WMA/AAC/FLAC (USB Flash drive) files Audio data is compressed using software with MP3/WMA/AAC/FLAC (USB Flash drive) codecs. For details on creating MP3/WMA/AAC/ FLAC (USB Flash drive) files, refer to the user's manual for that software. MP3/WMA/AAC/FLAC (USB Flash drive) files that are playable on this device have the file extensions. MP3: "mp3" WMA: "wma" AAC: "m4a" FLAC: "flac"/"fla" WMA is not supported for the following files, Windows Media Audio Professional, Windows Media Audio 10 std or Windows Media Audio 10 Pro Lossless. There are many different versions of the AAC format. Confirm that the software being used conforms to the acceptable formats listed above. It's possible that the format may be unplayable even though the extension is valid. Playback of AAC files encoded by iTunes is supported. Supported playback sampling rates and bit rates MP3 (USB Flash drive/Disc) Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 16 kHz, 12 kHz, 11.025 kHz, 8 kHz Bit rates: 8 - 320 kbps WMA (USB Flash drive/Disc) Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 22.05 kHz, 16 kHz, 11.025 kHz, 8 kHz Bit rates: 48 - 320 kbps AAC (USB Flash drive/Disc) Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 16 kHz, 12 kHz, 11.025 kHz, 8 kHz Bit rates: 16 - 320 kbps FLAC (USB Flash drive) Sampling rates: 96kHz, 88.2kHz, 48kHz, 44.1kHz, 32kHz, 24kHz, 22.05kHz, 16kHz, 8kHz Channel number: 1ch, 2ch This device may not play back correctly depending on sampling rates. 102-EN
