If the song being recorded has a name, press the NAME EDIT button of DHC-MD555 to edit or copy the name. The track name cannot be

recorded automatically for copyright reasons.

Up to 255 bytes (255 ASCII characters) can be transmitted for one track.
2 bytes are used for one Japanese kana character. As other special symbols are also added, the number of characters that can be transmitted

is almost halved.

*Time required for data transmission
Transmission is performed in packets (7 characters). Transmission of one packet takes about 100 ms for the MD player and about 40 ms for
the MD recorder.

If errors occur during transmission and reception due to effects of noise during data transmission, data will be lost in units of packets. In

this case, the lost data will not be included in the track name displayed.

For example, in the transmission of the track name 1234567ABCDEFG123, three packet data “1234567”, “ABCDEFG”, and “123” will

be sent. Should transmission or reception error at the second packet, the track name will be displayed as “1234567123”.

Illegal characters may be displayed rarely and randomly when the portable MD recorder is used. In this case, correct with the editing

function.

Only at the start of recording, detection that the sound data has exceeded a certain level will be performed, after which recording will be

started. After this, the track number will be set based on track data output from the MD Walkman. For this reason, the level synchro recording
function does not work during recording.

Track numbers may be assigned to positions different from playback when the portable MD recorder is used. In this case, reassign track

position by using the editing function.

When the portable MD player for playback is used, track numbers are assigned to the same position as that during playback.

Bi-directional communication is performed between the MD Walkman and system controller of the system stereo.

Liquid crystal display data is periodically output from the system controller of the MD Walkman. To copy the track name data, the data

transmission request command is output to the DATA terminal from the system controller of the system stereo, and the track name data is
transmitted from the system controller of the MD Walkman.
