Anleitung Zusammenfassung
• Do not touch it with wet hands. • Do not place heavy objects on top of it. • Do not forcibly bend it. • Be sure to connect only the AC adaptor provided with the unit. • Disconnect the AC adaptor from the power outlet if the unit is not going to be used for a long time. Unit No altering or remodelling This can cause malfunctioning. No dropping or strong impacts This may damage the unit. Locations to be avoided Avoid using the unit in the following locations since they can cause malfunctioning. 1. Bathrooms and other moisture-prone places. 2. Warehouses and other dusty places 3. Very hot places near heating appliances, etc. Do not leave the unit exposed to direct sunlight for long periods of time This may deform or discolor the cabinet and may also cause malfunctioning. Precautions for Listening with the headphones • Do not play your headset at a high volume. Hearing experts advise against continuous extended play. • If you experience a ringing in your ears, reduce volume or discontinue use. • Do not use while operating a motorized vehicle. It may create traffic hazard and is illegal in many areas. • You should use extreme caution or temporarily discontinue use in potentially hazardous situations. • Even if your headphones is an open-air type designed to let you hear outside sounds, don’t turn up the volume so high that you can’t hear what’s around you. When driving a car In the interest of traffic safety, do not operate the unit while driving. Information on MDs (Minidiscs) This is a new digital audio disc format: it has a diameter of 64 mm and enables up to 80 minutes of playback and recording. The cartridge The diameter of the disc itself is 64 mm, smaller than a CD single. The disc sits inside a 68 . 72 mm cartridge, which also being pocket size, makes minidiscs extremely handy for carrying and storage. Since the disc is protected by the cartridge, dust and dirt cannot easily get into it. And thanks to a shutter which is closed at all times except during use, there is no need to worry about scratches or finger marks, making the handling of minidiscs very simple. Two types of minidisc There are two types of minidisc, “recordable MDs” and “playback-only MDs.” The playback method for each is the same: a laser irradiates the disc and the signal is read from the beam which comes back. However, the recording method for each type is different. Playback-only MD This is the type used for commercially-available pre-recorded MDs, on which recording cannot be done. Like a CD, data is recorded based on the presence or absence of small indentations called pits. A disc recorded with this format is called an “optical disc.” Recordable MDs These are the so-called “blank” MDs you can use to make your own recordings. Data is recorded by magnetism, which is easily processed, so that recording can be done again and again. By using a laser to heat the disc, the magnetism is erased and the magnetic head records the new data. Discs with this type of recording method are called magneto-optical (MO) discs. 13 ATRAC (Adaptive Transform Acoustic Coding) Within recordings, there are sounds which cannot be readily heard. For example, as the volume decreases, high-pitched sounds and low-pitched sounds become difficult to hear. Also, if a quiet sound comes at the same time as or just after a loud sound, it will not be heard. With minidiscs, data is compressed using a technology called ATRAC (Adaptive Transform Acoustic Coding) which selectively chooses sounds based on human sense of hearing characteristics. With this technology, the recorded data is about one-fifth the volume of the original data, allowing it to fit on a compact minidisc.

Even when data cannot be collected properly from the disc due to shaking or vibrations, information is stored in the “sound skip guard memory”, so that there is no break in the sound which is actually delivered. UTOC (User Table Of Contents) In a minidisc, apart from the recorded tracks, there is the “UTOC”. In this area, information such as the position where each track is recorded, the track divisions, and track order are listed. When music search is done, the UTOC is consulted, and the tracks are quickly found and played back. When editing is done, only the UTOC is changed, so there is no need to re-record the tracks. English MD (Minidisc) Messages Message Meaning/Action A disc has been inserted with nothing recorded on it. BLANK DISC You have tried to join tracks which cannot be joined. CANNOT JOIN There is a problem (damage) with the disc. DISC ERROR (Replace the disc.) There is not enough space left on the disc. DISC FULL There are over 254 tracks. The disc is in accidental erasure pro...
