How to use this manual
This manual mainly explains operations using the remote, but the same operations can also be performed using the buttons on the unit having the same or similar names.
Discs that this system cannot play
CD-ROMs CD-Rs/CD-RWs other than those recorded in the following formats: music CD format MP3 format that conforms to ISO96601) Level 1/Level 2, Joliet or Multi Session2) A disc that has a non-standard shape (e.g., card, heart). A disc with paper or stickers on it. A disc that has the adhesive, cellophane tape, or a sticker still left on it.

CD-R/CD-RW (audio data/MP3 files*)
* MHC-GX750/GX450/RG555/RG551S/RG444S/ RG441/RG333/RG222/RG221/RX550 only
ISO9660 Format The most common international standard for the logical format of files and folders on a CD-ROM. There are several specification levels. In Level 1, file names must be in the 8.3 format (no more than eight characters in the name, no more than three characters in the extension.MP3) and in capital letters. Folder names can be no longer than eight characters. There can be no more than eight nested folder levels. Level 2 specifications allow file names and folder names up to 31 characters long. Each folder can have up to 8 trees. For Joliet in the expansion format (file and folder names can have up to 64 characters) make sure of the contents of the writing software, etc. Multi Session This is a recording method that enables adding of data using the Track-At-Once method. Conventional CDs begin at a CD control area called the Lead-in and end at an area called Lead-out. A Multi Session CD is a CD having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session. CD-Extra: This format records audio (audio CD data) on the tracks in session 1 and data on the tracks in session 2. Mixed CD: This format records data on the first track and audio (audio CD data) on the second and subsequent tracks of a session.
Notes on CD-R and CD-RW
Some CD-Rs or CD-RWs cannot be played on this system depending upon the recording quality or physical condition of the disc, or the characteristics of the recording device. Furthermore, the disc will not play if it has not been correctly finalized. For more information, see the operating instructions for the recording device. Discs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition or the drivers characteristics. CD-R and CD-RW discs recorded in multisession that have not ended by closing the session are not supported. The system may be unable to play MP3 format files that do not have the.MP3 extension. Attempting to play non-MP3 format files that have the.MP3 extension may result in noise or malfunction. With formats other than ISO9660 level 1 and 2, folder names or file names may not be displayed correctly. The following discs take a longer time to start playback. a disc recorded with complicated tree structure. a disc recorded in Multi Session. a disc to which data can be added (nonfinalized disc).
Music discs encoded with copyright protection technologies
This product is designed to playback discs that conform to the Compact Disc (CD) standard. Recently, various music discs encoded with copyright protection technologies are marketed by some record companies. Please be aware that among those discs, there are some that do not conform to the CD standard and may not be playable by this product.
Cautions when playing a disc that is recorded in Multi Session
If the disc begins with a CD-DA session, it is recognized as a CD-DA (audio) disc, and playback continues until an MP3 session is encountered. If the disc begins with an MP3 session, it is recognized as an MP3 disc, and playback continues until a CD-DA (audio) session is encountered. The playback range of an MP3 disc is determined by the tree structure of files produced by analyzing of the disc. A disc with a mixed CD format will be recognized as a CD-DA (audio) disc.

The effective areas of the transmitter
Wireless system that allows you to use your system free from the restriction of speaker cords. The optimum signal reception range is up to approximately 30.5 m (100 feet) without the system picking up some interference. However, the distance may be reduced according to the surroundings and environment. If the system picks up some noise while using it within the above mentioned distance, reduce the distance between the transmitter unit and the main unit, or select another channel.
Make sure the power cord and speaker cords are correctly and firmly connected. Find your problem in the troubleshooting checklist below and take the indicated corrective action.
If the problem persists after doing all of the above, consult your nearest Sony dealer.
When the ?/1 indicator flashes
Immediately unplug the power cord and check the following items. If your system has a voltage selector, is the voltage selector set to the correct voltage? Check the voltage for your region, then make sure the voltage selector is set correctly. Are the + and speaker cords shortcircuited? Are you using only the prescribed speakers? Is anything blocking the ventilation holes on the rear of the system? Check all the above items and fix any problems found. After ?/1 indicator stops flashing, reconnect the power cord and turn on the system. If the indicator still flashes, or if the cause of the problem cannot be found even after checking all the above items, consult your nearest Sony dealer.
The remote does not function. Remove the obstacle. Move the remote closer to the system. Point the remote at the systems sensor. Replace the batteries (R6/size AA). Locate the system away from the fluorescent light. There is acoustic feedback. Reduce the volume. For MHC-RG555, move the microphone away from the speakers or change the direction of the microphone. The color irregularity on a TV screen persists. Turn off the TV set once, then turn it on after 15 to 30 minutes. If the color irregularity still persists, place the speakers farther away from the TV set. The sound from the connected source is distorted (MHC-RG555 only). If VIDEO appears in the display when you press VIDEO/MD on the unit, switch the display to MD (see Listening to audio from a connected component (MHC-RG555 only) on page 30).
