Precautions

On safety
Do not put any foreign objects in the DC IN 3V jack.

Road safety

Do not use headphones/earphones while driving, cycling, or operating any motorized vehicle. It may create a traffic hazard and is illegal in many areas. It can also be potentially dangerous to play your recorder at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations.

On power sources

Use house current, nickel metal hydride rechargeable battery, LR6 (SG) battery, or car battery. For use in your house: For the supplied battery
charging stand, 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.
Preventing hearing damage
Avoid using headphones/earphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce the volume or discontinue use.

Polarity of the plug

Make sure to connect the AC power adaptor to a wall outlet that is within easy reach, and disconnect it quickly if an unusual condition arises. 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.

Caring for others

Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate of the people around you.
On the MiniDisc cartridge
When carrying or storing the MiniDisc, keep it in its case. Do not break open the shutter. Do not place the cartridge where it will be subject to light, extreme temperatures, moisture or dust.

Quick Random Access

Explanations

What is Net MD?

Net MD is a format of that allows the highspeed transfer of audio data from a computer to a MiniDisc device over a USB (Universal Serial Bus) cable using the highly sophisticated OpenMG and MagicGate copyright protection technology. Since this format entails no change in the MiniDisc recording system, it supports the use of existing MiniDiscs and the playback of transferred (checked-out) audio data on existing MiniDisc devices.* This format also allows the use of the OpenMG Jukebox software for easy editing or input of characters on your personal computer.
Audio data transferred in LP mode must be played on MiniDisc devices that support MDLP mode.
Like CDs, MDs offer instantaneous random access to the beginning of any music track. Premastered MDs are recorded with location addresses corresponding to each music selection. Recordable MDs are manufactured with a User TOC Area to contain the order of the music. The TOC (Table of Contents) system is similar to the directory management system of floppy disks. In other words, starting and ending addresses for all music tracks recorded on the disc are stored in this area. This lets you randomly access the beginning of any track as soon as you enter the track number (AMS), as well as label the location with a track name as you would a file on a diskette.
How the MiniDisc got so small
The 2.5-inch MiniDisc, encased in a plastic cartridge that looks like a 3.5-inch diskette, uses a new digital audio compression technology called ATRAC (Adaptive TRansform Acoustic Coding). To store more sound in less space, ATRAC extracts and encodes only those frequency components actually audible to the human ear.

MZ-N1 SECTION 4 TEST MODE

Outline

This set provides the Overall adjustment mode that allows CD and MO discs to be automatically adjusted when in the test mode. In this overall adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be automatically adjusted. Operation in the test mode is performed with the set. A key having no particular description in the text, indicates a set key. For the LCD display, the LCD on the remote commander is shown, but the contents of LCD display on the set are same.

Rewriting the Patch Data at Replacement of Main Board or Nonvolatile Memory (IC802)
This set requires the patch data in the nonvolatile memory (IC802) to be rewritten using the application, when the MAIN board or nonvolatile memory (IC802) was replaced. Caution: The application that meets the microcomputer version in this set must be used when rewriting the patch data. Rewriting the patch data using the application not suitable for the microcomputer version could cause the set to malfunction. For a checking method of the microcomputer version, see SECTION 4 TEST MODE (page 13). Preparation 1. USB cradle (attached to the set) 2. USB cable (attached to the set) 3. Personal computer in which the Net MD Driver has been installed. (For further information, see System requirements (page 4) in SECTION 1 SERVICING NOTES) 4. Application PatchWriter for patch data rewriting How to get the application PatchWriter for patch data rewriting Contact our service technical support division to get the application. Pre-check 1. Check the microcomputer version in this set. (For a checking method of the microcomputer version, see SECTION 4 TEST MODE (page 13).) 2. Check that the Net MD Driver has been installed in the personal computer. 3. Make sure that the set is in the Normal mode.
