MD4S
DISC FOR MD4S
It's important that you buy the correct type of disc for use with your MD4S. For 4-track recording and playback, you must use MD DATA discs. Regular MiniDiscs can only be used for 2-track recording and playback (2 TR mode). MD DATA discs are used as a storage media for computers. The MD4S uses the MD DATA audio format to store data on them. Regular MiniDiscs are also referred to as MD discs, although they are used only for music. Type Logo Description MD DATA discs are for computer data storage applications. You can purchase them at computer stores. This is the type of disc you should buy for 4-track recording and playback with your MD4S. Note that there are two types available: playback only and rewritable. Buy the rewritable type. MiniDiscs are used only for music. Two types are available: playback only and recordable. The MD4S can record up to two tracks on the recordable type and play the playback only type.
MD DATA
MiniDisc
New MD DATA discs do not require formatting before use with the MD4S. Discs that have been used to store computer data, however, must first be formatted. Regular MiniDisc decks cannot play MD DATA discs. Regular MiniDiscs recorded on the MD4S can be played on a regular MiniDisc deck. MiniDisc recordings made on a regular MiniDisc deck can be edited on the MD4S. MiniDiscs containing songs that were digitally copied from a commercial CD, however, cannot be edited due to the SCMS (Serial Copy Management System) protection system. Songs that were recorded in 8-track mode on a recorder such as the MD8 cannot be played back on the MD4S.

EPROM(IC104)REMOVAL AND INSTALLATION
1. 1-1 Removing the EPROM Insert a sharp tweezers into the gap of socket and lift the one side of EPROM by hooking it. When the one side is raised, insert the tweezers into other gap and lift the EPROM as well. (Fig. 1, Fig. 2 and Fig. 3) 1-2 Repeat the procedure in 1-1 alternately to remove the EPROM. Note: If the tweezers is hooked too strongly, the EPROM jumps up and breaks. Remove the EPROM by pressing down with a finger as shown in Fig. 2. 2. 2-1 Installation of the EPROM Put the EPROM on the socket, then check that the EPROM moves slightly by moving it gently with a finger. (Fig. 4) 2-2 Set the EPROM into the socket by pressing down until it clicks. (Fig. 5) Note: Be sure to check the following items after the installation of EPROM. 1. Four corners of EPROM are securely fit in the frame. 2. There is no damage with hooks or defective hooking.

The STOP button was pressed, so the Adjust function was cancelled. The MD4S is located at the Blank Top position. The disc is blank. MD4S cannot combine these two songs because they were not split using the Song Divide function, or MD4S cannot edit this type of song. This song cannot be copied because it's copy protected. The MD4S cannot record over this type of song, so you cannot overwrite this song. The MD4S does not have permission to record in this mode, so you cannot rehearse a recording that would overwrite this song. MIDI Clock was turned OFF automatically because you selected the Program Play or Cue List function. The STOP button was pressed, so the Song Copy, Track Copy, Part Copy, or Cue List Copy function was cancelled. A disc scratch or defect was discovered while recording. Replace the disc. The disc is full. You cannot record any more data or additional takes (Multi Take Auto Punch In). The STOP button was pressed, so the Track Erase or Part Erase function was cancelled. This song has been write protected by another recorder. Press the ENTER button to erase or the EXIT button to cancel. A fatal error occurred. Contact your Yamaha dealer. The IN or OUT point is not valid, so you cannot use Auto Punch In/Out. Since this song is not compatible with the MD4S, it cannot be played. The cue list is invalid. No more markers can be inserted because the song contains the maximum of eight, or you tried to insert a marker at the position of an existing marker. The STOP button was pressed, so the Song Move function was cancelled. MTC was turned OFF automatically because you selected the Program Play or Cue List function. No blank area can be found for further recording. No disc is loaded. Because the STOP button was pressed, the off-line punch-in/out function was aborted. The disc's write protect tab is set to protect, so you cannot record. The MD4S is reading the TOC from disc. The MD4S is waiting for you to reload the disc. Not all the Tempo Map steps can be saved because the data area is full. The TOC area is full, so not all of the song title or Tempo Map could be saved. The MD4S is writing the TOC to disc.
