About CD-R and CD-RW discs
CD-R discs can be recorded once only. Once they have been used for recording, they cannot be erased or re-recorded. However, if space is available on the disc, additional material can be recorded. The pack-aging of CD-R discs will include one of the following logos: CD-R and CD-RW discs are sensitive to the effects of heat and ultraviolet rays. It is important that they are not stored in a location where direct sunlight will fall on them, and which is away from sources of heat such as radiators or heat-generating electrical devices. Always store CD-R and CD-RW discs in their cases to avoid dirt and dust accumulating on their surfaces. By contrast, a CD-RW disc can be used in much the same way as a CD-R disc, but the last track or tracks recorded can be erased before the disc has been finalized, and the space on the disc can be re- used for other recordings. The packaging of CD-RW discs will include the logo one of the following logos:

HighSpeed

When labeling CD-R and CD-RW discs, always use a soft oil-based felt-tipped pen to write the information. Never use a ball-point or hard-tipped pen, as this may cause damage to the recorded side. Always keep the recording sides of the discs away from grime and dust to avoid a reduction in sound quality. To clean a disc, wipe gently with a soft dry cloth from the center towards the outside edge. Do not use thinner, gasoline, benzene or LP cleaning fluid, as these will damage the disc and cause the disc unplayable. Do not put labels or protective sheets on the discs and do not use any protective coating spray. If you are in any doubt as to the care and handling of a CD-R and CD-RW discs, read the precautions supplied with the disc, or contact the disc manufacturer directly.

However, you should note that an audio CD created using a CD-RW901 disc may not play back satisfactorily on every audio CD player. It will, naturally, be playable on the CD-RW901. This is in no way a limitation of the CD-RW901 itself, but of the difference between the different types of media and the methods used to read them. There are precautions that you should take when handling CD-R and CD-RW discs. Avoid touching the recording (non-label) side of a disc on which you will be recording. Recording on a disc requires a cleaner surface than playing back, and fingerprints, grease, etc. can cause errors in the recording process.

About finalizing

Although audio data may be written on a CD-R or CD-RW disc, a standard CD player will not be able to read the data (i.e. play back the audio) until a final *TOC has been written at the start of the disc.
*TOC:Table of contents Information of recorded data, which contains titles, starting and ending addresses, and etc.
data can be written to the disc. See Finalizing on page 31 for details. In the case of a CD-RW disc which has been finalized, the whole of the disc may be erased, or the disc may be refreshed, and the disc re-used. In addition, a CD-RW disc that has been finalized may be unfinalized, i.e. only the TOC is removed. This allows further tracks to be recorded to the disc, provided that there is space on the disc.
The process of writing this table of contents is known as finalizing. Once this has been done, no further

Recordable discs

In this manual, we use the term recordable disc to describe a CD-R or CD-RW disc that has not been finalized, i.e. further recording is possible on the disc.
Environmental considerations
The CD-RW901 may be used in most areas, but to maintain top performance, and prolong operating life, observe the following environmental conditions: The nominal temperature should be between 5C and 35C (41F and 95F). Relative humidity should be 30 to 90 percent. As the unit may become hot during operation, always leave sufficient space above the unit for ventilation. Do not install this unit in a confined space such as a bookcase, and do not put anything on top of the unit. Avoid installing this unit on top of any heat-generating electrical device such as a power amplifier. Make sure that the unit is mounted in a level position for correct operation.
The voltage supplied to the unit should match the voltage as printed on the rear panel. If you are in any doubt regarding this matter, consult an electrician.
Handling of compact discs
The CD-RW901 has been designed for the playback of CD-DA (standard audio) format discs and MP3 files recorded on the discs using the ISO9660 format: In addition to ordinary 5-inch and 3-inch CDs, it can also play properly recorded CD-R and CD-RW discs. Always place the compact discs in the trays with their label facing upward. To remove a disc from its case, press down on the center of the disc holder, then lift the disc out, holding it carefully by the edges. Do not affix any labels or stickers to the label side of the disc. Do not write on the disc with a ballpoint pen. Do not insert discs that have adhesive remaining from tape or stickers that have been removed. If they are inserted into the player, they could stick to the internal mechanism, requiring removal by a technician. Do not use cracked discs. Only use circular compact discs. Avoid using noncircular promotional, etc. discs.

3.1. Command format overview The command format is as follows. Byte 1 LF Byte 2 ID Byte 3 Byte 4 Command Byte 5 Data 1 Byte 6 Data 2 Byte 7 Data 3 Byte 8 Data 4 Byte n CR
Commands begin with a "line feed (LF)," end with a "carriage return (CR)," and are based on the ASCII format. The type following the LF is the machine ID. The machine ID is described later. Commands are expressed by two ASCII bytes. The byte string following the command expresses the data, and is between 0 bytes (for a command that has no data) and a maximum of 98 bytes. For details on the data, refer to the detailed explanation for each command. For commands that use 0--9 and A--F as data values, uppercase characters are used for A--F. Example commands Example 1: Transmitting a PLAY command to a controlled device of ID=0 When the controlled device is in Stop or Ready mode, this command will initiate playback on the controlled device. The PLAY command is [12], and is transmitted as follows. ID Command ASCII LF 2 CR HEX 0Ah 30h 31h 32h 0Dh Example 2: Telling a controlled device of ID=0 to perform a direct search for track 123 The command "DIRECT TRACK SEARCH PRESET [23]" is transmitted to perform this action. The data bytes consist of ASCII in two-byte units. For the "DIRECT TRACK SEARCH PRESET" command, the track number is specified as follows. Data 1 Tens digit of the specified track number Data 2 Ones digit of the specified track number Data 3 Thousands digit of the specified track number Data 4 Hundreds digit of the specified track number Thus, the transmitted command will be as follows. ID Command Datatrack 123 ASCII LF 1 CR HEX 0Ah 30h 32h 33h 32h 33h 30h 31h 0Dh Example 3: Writing a title to track 23 of a controlled device whose ID=0 The command "TEXT PRESET [29]" is transmitted to perform this action. This command allows up to eighty single-byte characters to be transmitted. For example, the command to write a title "Test" would be as follows. ID Command Track 23 Title Test ASCII LF 1 T e s HEX 0Ah 30h 32h 39h 32h 33h 30h 30h 54h 65h 73h

3.4. Command sequence In most cases the controlled device will not send an ACK in response to transport control or data preset commands sent from the external controller. The controlled device will send back a return command in response to data sense commands that request a data value specified on the controlled device. When the status of the controlled device changes, such as from Stop to Play mode, or when an error etc. occurs, the controlled device will send a command indicating this to the external controller. Examples of the command sequence are given below. You must leave an interval of at least 20 ms between commands. Example 1: Controlling the transport of the controlled device This example describes the Play operation. When the controlled device receives the PLAY command and enters Play mode, it will transmit a CHANGED STATUS command. ACK is not transmitted for the PLAY command. Command State of controlled device External controller Controlled device Stopped PLAY -> <- CHANGED STATUS Transmit when starting Play Example 2: Presetting data This example describes setting the AUTO CUE LEVEL. When the controlled device receives the AUTO CUE LEVEL PRESET (Preset) command, it will set its AUTO CUE LEVEL. ACK is not transmitted for this command. Command State of controlled device External controller Controlled device AUTO CUE LEVEL set to AUTO CUE LEVEL -> -54dB PRESET (Preset -54dB) Example 3: Obtaining specified data This example describes obtaining the currently-set AUTO CUE LEVEL. When the controlled device receives the AUTO CUE LEVEL PRESET (Sense) command, it will return the currently-set AUTO CUE LEVEL. Command State of controlled device External controller Controlled device AUTO CUE LEVEL -> PRESET (Sense) AUTO CUE LEVEL <RETURN Example 4: Checking the status of the controlled device, and performing the next operation When the operating status of the controlled device changes, it will transmit CHANGED STATUS. By using CHANGED STATUS as a trigger for sending MECHA STATUS SENSE, the new operating status can be determined. This example shows how to check the record-ready status of the controlled device and then initiate recording. Command State of controlled device External controller Controlled device Stopped RECORD (Record Ready) ->

<MECHA STATUS SENSE -> <RECORD (Record) -> <-
