Precautions
On safety
• As the laser beam used in the CD player
section is harmful to the eyes, do not
attempt to disassemble the casing. Refer
servicing to qualified personnel only.
• Should any solid object or liquid fall into
the player, unplug the player, and have it
checked by qualified personnel before
operating it any further.
• Discs with non-standard shapes (e.g.,
heart, square, star) cannot be played on
this player. Attempting to do so may
damage the player. Do not use such discs.
Cleaning the cabinet
• Clean the cabinet, panel and controls with
a soft cloth slightly moistened with a mild
detergent solution. Do not use any type of
abrasive pad, scouring powder, or solvent,
such as alcohol or benzine.
On power sources
• For AC operation, use the supplied AC
power cord; do not use any other type.
• The player is not disconnected from the
AC power source (mains) as long as it is
connected to the wall outlet, even if the
player itself has been turned off.
• Unplug the player from the wall outlet
when it is not to be used for an extended
period of time.
• For battery operation, use six size D (R20)
batteries.
• When the batteries are not to be used,
remove them to avoid damage that can be
caused by battery leakage or corrosion.
• The nameplate indicating operating
voltage, power consumption, etc. is
located at the bottom.
On placement
• Do not leave the player in a location near
heat sources, or in a place subject to direct
sunlight, excessive dust or mechanical
shock.
• Do not place the player on an inclined or
unstable place.
• Do not place anything within 10 mm of
the side of the cabinet. The ventilation
holes must be unobstructed for the player
to operate properly and prolong the life of
its components.
• If the player is left in a car parked in the
sun, be sure to choose a location in the car
where the player will not be subjected to
the direct rays of the sun.
• Since a strong magnet is used for the
speakers, keep personal credit cards using
magnetic coding or spring-wound watches
away from the player to prevent possible
damage from the magnet.
On operation
• If the player is brought directly from a
cold to a warm location, or is placed in a
very damp room, moisture may condense
on the lenses inside the CD player section.
Should this occur, the player will not
operate properly. In this case, remove the
CD and wait about an hour for the
moisture to evaporate.
• If the player has not been used for a long
time, set it in the playback mode to warm
it up for a few minutes before inserting a
cassette.
