Notes on playing MP3 discs
Do not save other types of files or unnecessary folders on a disc that has MP3 files. Folders that have no MP3 files are skipped. MP3 files are played back in the order that they are recorded onto the disc. The system can only play MP3 files that have a file extension of.mp3. Even when file name has the.mp3 file extension, if the actual file differs, playing this file may generate a loud noise which could damage the speaker system and the system may malfunction. The maximum number of: folders is 150 (including the root folder). MP3 files is 255. MP3 files and folders that can be contained on a single disc is 300. folder levels (the tree structure of files) is 8. Compatibility with all MP3 encoding/writing software, recording device, and recording media cannot be guaranteed. Incompatible MP3 discs may produce noise or interrupted audio or may not play at all.

Precautions

Discs that this system CAN play Audio CD CD-R/CD-RW (audio data/MP3 files) Discs that this system CANNOT play CD-ROM CD-R/CD-RW other than those recorded in music CD format or MP3 format conforming to ISO9660 Level 1/Level 2, Joliet CD-R/CD-RW recorded in multisession that have not ended by closing the session CD-R/CD-RW of poor recording quality, CD-R/CD-RW that have scratches or are dirty, or CD-R/CDRW recorded with an incompatible recording device CD-R/CD-RW which is finalized incorrectly Discs containing files other than MPEG 1 Audio Layer-3 (MP3) files Discs of non-standard shape (for example, heart, square, star) Discs that have adhesive tape, paper, or sticker attached to them Rental or used discs with attached seals where the glue extends beyond the seal Discs that have labels printed using ink that feels tacky when touched
Notes on discs Before playing, wipe the disc with a cleaning cloth from the centre out to the edge. Do not clean discs with solvents, such as benzine thinner, or commercially available cleaners or anti-static spray intended for vinyl LPs. Do not expose discs to direct sunlight or heat sources such as hot air ducts, nor leave it in a car parked in direct sunlight. On safety Completely disconnect the power cord (mains lead) from the wall outlet (mains) if it is not going to be used for an extended period of time. When unplugging the unit, always grip the plug. Never pull the cord itself. Should any solid object or liquid get into the system, unplug the system, and have it checked by qualified personnel before operating it again. AC power cord must be changed only at the qualified service shop.

On placement Do not place the system in an inclined position or in locations that are extremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation, or subject to vibration, direct sunlight or a bright light. Be careful when placing the unit or speakers on surfaces that have been specially treated (for example, with wax, oil, polish) as staining or discoloration of the surface may result. If the system is brought directly from a cold to a warm location or is placed in a very damp room, moisture may condense on the lens inside the CD player, and cause the system to malfunction. In this situation, remove the disc, and leave the system turned on for about an hour until the moisture evaporates.
On heat buildup Heat buildup on the unit during operation is normal and is not cause for alarm. Do not touch the cabinet if it has been used continuously at a high volume because the cabinet may have become hot. Do not obstruct the ventilation holes. On the speaker system This speaker system is not magnetically shielded, and the picture on nearby TV sets may become magnetically distorted. In this situation, turn off the TV, wait 15 to 30 minutes, and turn it back on. If there is no improvement, move the speakers far away from the TV. Cleaning the cabinet Clean this system with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as thinner, benzine, or alcohol.
To prevent a tape from being accidentally recorded over (MHCEC99T/EC79T/EC69T only) Break off the cassettes overwrite protection tab from side A or B as illustrated.
