BAdditional information
Precautions
On safety
• Make sure to keep the player in the supplied carrying pouch. If the
terminals on the player, battery charging stand, or battery case are
accidently brought into contact with a metallic object, they may short-
circuit and begin to heat up.
• Keep the terminals on the player or on the battery case away from
metallic objects or surfaces. Such contact may short-circuit the
terminals and cause dangerous heat generation. When carrying the
player with you, always keep the battery case attached to the player
and the player in the supplied carrying pouch.
• When you carry the supplied rechargeable battery, be sure to put it in
the supplied rechargeable battery carrying case. Carrying the
rechargeable battery without the case may cause a short-circuit with
metallic objects such as coins, key rings, or necklace. As a result, heat
may be generated.
• Do not put any foreign objects in the DC IN 3V jack.
• Do not carry or store the dry battery or battery case in the same place
with metallic objects such as coins, key rings, or necklaces. This may
cause a short-circuit to occur and heat to generate.
• Incorrect battery usage may lead to leakage of battery fluid or bursting
batteries. To prevent such accidents, observe the following
precautions:
— Install batteries with the + and – poles aligned correctly.
— Do not charge dry batteries.
• If a battery leak should develop, carefully and thoroughly wipe away
battery fluid from the battery compartment before inserting new one.
• If you are not going to use this player for a long time, be sure to
disconnect the power supply (AC power adaptor, dry battery,
rechargeable battery, or battery charging stand). To remove the AC
power adaptor from the electrical outlet, grasp the adaptor plug itself;
never pull the cord.
On the AC power adaptor (for the supplied
battery charging stand)
• For use in your house: Use the supplied AC power adaptor
AC-E30HG. Do not use any other AC power adaptor since it may
cause the player to malfunction.
Polarity of the plug
• Position the player within easy reach of the electrical outlet. Should
you notice an abnormality in the player, disconnect the AC power
adaptor from the electrical outlet immediately.
On charging
• The supplied battery charging stand can be used only with the
MZ-E501. It cannot be used to charge all other models.
• Do not use the MZ-E501 to charge any other battery besides the one
designated for it.
• Though the battery charging stand and the battery may become hot
during the charging procedure, this poses no danger.
• Because of the battery’s character, the capacity of the battery may be
smaller than normal when it is used for the first time or after a long
period of disuse. In this case, charge and discharge the battery several
times. The normal battery life will be restored.
• If the capacity of the rechargeable battery becomes half the normal life,
replace it with a new one.
• As soon as charging is complete, remove the player from the battery
charging stand and disconnect the battery charging stand from the
electrical outlet. Leaving it connected may result in reduced battery
performance.
• The CHARGE lamp will go off about 6 hours of after you place the
player on the battery charging stand. If you remove the player from
the battery charging stand for 3 seconds or more while it is charging,
the CHARGE lamp will go off. It will then take about 6 hours for the
lamp to go off from the time you next place the player on the battery
charging stand.
On Handling
• Do not drop or bump the player. This may cause the player to
malfunction.
• Do not pull on the remote control or headphones/earphones cords.
• Do not place the player in the following places:
— An extremely hot place (over 60°C (140°F))
— A place exposed to direct sunlight or near a heater
— In a car with the windows rolled up (especially in the summer)
— In a damp place such as a bathroom
— Near a source of electromagnetic fields such as a magnet, speaker, or
TV
— In a dusty place
On heat build-up
Heat may build up in the player if it is used for an extended period
of time. This, however, is not a malfunction.
On mechanical noise
The player gives out mechanical noise while operating, which is
caused by the power-saving system of the player. This is not a
malfunction.
On installation
• Never use the player where it will be subjected to extremes of light,
temperature, moisture or vibration.
• Never wrap the player in anything when it is being used with the AC
power adaptor. Heat build-up in the player may cause malfunction or
injury.
On the remote control
The supplied remote control is designed for use with the MZ-E501
only. Note also that the player cannot be controlled by remote
controls for other models.
On the MiniDisc cartridge
• Do not touch the internal disc directly. Forcing the shutter open may
damage the internal disc.
• When transporting a minidisc, keep it in its case.
• Do not place the cartridge where it will be subjected to light,
temperature, moisture or dust.
• Do not affix the lable outside of the specified area on the MD. Make
sure the lable is placed within the recessed space on the disc.
On the headphones/earphones
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 player at
high volume while walking, especially at pedestrian crossings. You
should exercise extreme caution or discontinue use in potentially
hazardous situations.
• If you experience an allergic reaction to the supplied headphones/
earphones, stop using them at once and consult a doctor or a Sony
service center.
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.
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 battery case
The supplied battery case is designed for use with the MZ-E501 only.
On cleaning
• After wiping the player casing with a soft cloth slightly moistened with
water, wipe it again with a dry cloth. Do not use any type of abrasive
pad, scouring powder or solvent such as alcohol or benzene as it may
mar the finish of the casing.
• Wipe the disc cartridge with a dry cloth to remove dirt.
• Dust on the lens may prevent the unit from operating properly. Be
sure to close the disc compartment lid after inserting or ejecting an
MD.
• A dirty plug may cause noise or intermittent breaks in the sound
during playback. To maintain good sound quality, use a soft cloth to
clean the plugs of the headphones/earphones and remote control.
