Selecting fine audio equipment such as the unit youve just purchased is only the start of your musical enjoyment. Now its time to consider how you can maximize the fun and excitement your equipment offers. This manufacturer and the Electronic Industries Associations Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your hearing comfort level adapts to higher volumes of sound. So what sounds normal can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
Start your volume control at a low setting. Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
Set the dial and leave it there. Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Associations Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.
Decibel Level Example Quiet library, soft whispers Living room, refrigerator, bedroom away from traffic Light traffic, normal conversation, quiet office Air conditioner at 20 feet, sewing machine Vacuum cleaner, hair dryer, noisy restaurant Average city traffic, garbage disposals, alarm clock at two feet.
THE FOLLOWING NOISES CAN BE DANGEROUS UNDER CONSTANT EXPOSURE 180 Subway, motorcycle, truck traffic, lawn mower Garbage truck, chain saw, pneumatic drill Rock band concert in front of speakers, thunderclap Gunshot blast, jet plane Rocket launching pad

Cautions regarding use of rechargeable battery
(Rechargeable Nickel Metal Hydride Battery NB -150)
Do not use any battery other than the specially provided rechargeable battery. Use of another battery will damage the unit. The battery is a rechargeable Nickel Metal Hydride battery. Because of the properties of this battery, it must be recharged at least once every 2 months, even if it is not used. The battery can be recharged about 500 times. If the battery is repeatedly recharged before its charge is completely used up, the battery service time may gradually decrease. This is due to the properties of the battery and does not indicate a malfunction. Allow the battery to be used up completely and then charge it fully. If this procedure is repeated several times, the rechargeable battery will display its proper performance. Replace the rechargeable battery with a new one when its service time is short even after it has been charged. (Use the separately sold NB-150S battery.) A small amount of power is used even when the unit is turned OFF. If the unit is not used for a long time, therefore, remove the battery and store it in a safe place. During battery charging or use of the unit, the battery may become warm. This is normal and does not indicate a malfunction.

In case of difficulty

If you think the unit is not operating properly, check the symptoms before requesting service.

Simple care

When dirty
Wipe with a dry, soft cloth.If the unit is very dirty, moisten the cloth slightly and wipe off the dirt. Afterwards, make sure you wipe the unit dry with a dry cloth.

Troubleshooting

Symptom Unit fails to turn ON. Cause The disc holder is not securely closed. The battery is depleted. HOLD status is engaged. The volume is at minimum level. The remote control or headphones are disconnected. HOLD status is engaged. The battery is depleted. The remote control or headphone plug is not securely inserted. The disc holder is not securely closed. The disc is scratched or damaged or the recording is not good. The unit is in a place where there is excessive vibration. Remedy Close disc holder securely. Charge the battery. Deactivate HOLD status. Increase the volume. Insert plug securely. Deactivate HOLD status. Charge the battery. Insert plug securely. Close disc holder securely. Replace the MD. Move the unit to a place where there is little vibration or set to PS off. Use the special rechargeable battery (NB-150) Wait until the unit has cooled to normal temperature. Use the accessory AC adaptor.
Taking care of plugs etc.
Always keep the plugs of headphones etc. clean. Dirtyplugs can cause noise or failure of remote control operation. 1. Do not use chemicals like benzine, thinner, etc., as they can cause deterioration and discoloration. 2. Do not apply oil to the unit, for this will cause it to malfunction.

There is no sound.

The unit does not respond to key operation.

Handling of Mini Disc

Since the MD is in a cartridge, it can be handled without worrying about dirt or fingerprints. But soiling, warping, or other damage to the cartridge will result in faulty operation. Take the following precautions to ensure that you will always be able to enjoy the music on your MDs.

Sound skips.

Do Not Touch the MD Directly

Battery indicator

For handy reference, the remaining battery life is indicated on the display while the unit is in operation. When the remaining battery power drops, the battery indicator on the main unit display blinks and the LCD display on the remote control unit is reversed. If the unit continues to be used after this condition, the remote control unit LCD shows LoBATT and the power is turned off automatically.
Do not open the shutter and directly touch the MD. Forcing the shutter open will damage it.

Storage Location

Care and Maintenance
Using a dry cloth, wipe dirt or dust off the cartridge at regular intervals.
Do not store MDs in direct sunlight or in hot locations such as car interiors or in humid locations. Do not leave MDs on a beach or other location where sand or dirt can enter the cartridge.
