CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure.

On power sources

•Use house current, LR6 (size AA) battery.

•For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfunction.

Polarity of the plug

Notes on chip component replacement

•Never reuse a disconnected chip component.

•Notice that the minus side of a tantalum capacitor may be dam- aged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 ˚C dur- ing repairing.

•Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

•Be careful not to apply force on the conductor when soldering or unsoldering.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

•Unleaded solder melts at a temperature about 40 ˚C higher than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to about 350 ˚C .

Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!

•Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.

•Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

MZ-S1 specifications

The Sony MZ-S1 is a portable MiniDisc recorder that reflects Sony's commitment to innovation in the realm of digital audio technology. Launched in the early 2000s, this model stood out for its sophisticated design and advanced features, catering to audiophiles and casual listeners alike. The MZ-S1 was particularly popular for its ability to record audio in a compact format, making it an attractive option for those who desired high-quality sound in a portable package.

One of the defining characteristics of the MZ-S1 is its use of MiniDisc technology, which allowed users to record and store audio with impressive sound quality. It leveraged Sony’s ATRAC (Adaptive Transform Acoustic Coding) compression, ensuring that recordings maintained clarity while efficiently utilizing disk space. The MZ-S1 supported various recording modes, including SP (Standard Play) and LP (Long Play), providing flexibility in terms of sound quality and recording duration. This capability made the MZ-S1 an ideal choice for musicians looking to record rehearsals, as well as for consumers wanting to create custom playlists.

The MZ-S1 features a sleek, compact design that embodies the portability and aesthetics of early 2000s electronics. Its user-friendly interface is complemented by an LCD display that provides essential information such as track numbers, remaining recording time, and battery life. Additionally, the MZ-S1 was equipped with various connectivity options, including a line-in for direct recording from external sources and a headphone jack with volume control for private listening.

Powering the device was a rechargeable battery, which allowed for extended use without the need for constant replacements. The MZ-S1 also featured a durable construction, appealing to users who needed a reliable audio recorder for travel or outdoor use. This model proved particularly popular among students, journalists, and music enthusiasts, as its compact size and high-quality output made it an indispensable tool for capturing audio on the go.
