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, nickel metal hydride rechargeable battery, LR6 (size AA) battery, or car battery.

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

Polarity of the plug

Connect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnormality in the AC power adaptor, disconnect it from the AC outlet immediately.

The recorder is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the recorder itself has been turned off.

If you are not going to use this recorder for a long time, be sure to disconnect the power supply (AC power adaptor, dry battery, rechargeable battery, or car battery cord). To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.

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-N510CK specifications

The Sony MZ-N510CK is a sophisticated mini-disc player that epitomizes the blend of portability and high-fidelity audio technology. Introduced in the early 2000s, this device became a favorite among audiophiles and casual listeners alike due to its compact design and impressive features. One of the standout characteristics of the MZ-N510CK is its ability to record in both SP and LP mode. SP mode offers crisp, CD-quality sound, while LP mode allows users to store more audio tracks onto a single disc, providing flexibility for users who prioritize capacity over audio fidelity.

The MZ-N510CK is equipped with Sony’s ATRAC (Adaptive Transform Acoustic Coding) technology. This lossy compression algorithm was designed to reduce the size of audio files without significantly compromising sound quality. With ATRAC, users can enjoy extended playtime on their mini-discs while maintaining an enjoyable listening experience. This makes the device particularly useful for long trips or extended listening sessions.

Another key feature of the MZ-N510CK is its superb battery life. Sporting an efficient power management system, the player can provide several hours of playback on just a single charge. This is especially advantageous for users who frequently travel, as it minimizes downtime waiting for the device to recharge.

The MZ-N510CK also boasts a sleek, user-friendly interface that enhances its overall usability. The easy-to-read LCD screen allows users to navigate through tracks seamlessly. Additionally, this model comes with a skip-free playback feature, which is particularly helpful during activities like jogging or walking, where bumps and jostles might typically disturb audio playback.

For connectivity, the MZ-N510CK includes a USB port, facilitating easy transfer of music files from a computer to the mini-disc. This connectivity feature was relatively advanced for the time, making the device more versatile in an era where digital music was rapidly on the rise.

In essence, the Sony MZ-N510CK presents an impressive package of features: high-quality audio recording options, cutting-edge compression technology, long battery life, a convenient interface, and strong connectivity options. Its combination of portability and performance makes it a remarkable device that continues to be appreciated by those who value high-quality sound in a compact format.
