Caution : Read this section carefully to ensure safe operation.
Cautions regarding use of rechargeable battery (Rechargeable
Nickel Metal Hydride Battery NB -130)
÷ 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-130 / NB-130S
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.
Checking the remaining battery life and charge status
For handy reference, the remaining battery life is indicated on the display while the
unit is in operation.
÷ When the remaining battery life is low, the scale will disappear. If the battery is
used further, the remaining battery life display will start to flash. If you continue
to use the unit under these conditions, the "LoBATT" indicator on the remote
control will be displayed and the power will automatically be turned off.

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.
Do Not Touch the MD Directly Storage Location

the cartridge at regular intervals.
Affixing the Label
÷ When affixing a label on the cartridge, take the following precautions and affix it
properly.
1 Properly affix the label in its prescribed place.
2 Do not affix a label over another label.
3 Avoid air bubbles and turned-back corners.
÷ If the label is not properly affixed, it may get stuffed into the cartridge, making it
impossible to remove the disc.
÷ If the label is not properly affixed, peel it off carefully and affix it properly.
Caution on condensation
Condensation (of dew) may occur inside the unit when there is a great difference in
temperature between this unit and the outside.
This unit may not function properly if condensation occurs. In this case, leave the unit
for a few hours with the power left ON, and restart the operation after the
condensation has dried up.
Be specially cautious against condensation in a following circumstance:
When this unit is carried from a place to another across a large difference in
temperature, when the humidity in the room where this unit is installed increases,
