Precautions
 General
 Do not place anything on top of the unit.
 Do not expose the unit to moisture, to temperatures higher than
60 ˚
C (140
˚
F) or to extremely low temperatures.
 If your system does not work properly, disconnect the AC power
lead from the wall socket. Plug the AC power lead back in, and
then turn on your system.
 No naked flame sources, such as lighted candles, should be
placed on the apparatus.
 Attention should be drawn to the environmental aspects of battery
disposal.
 This unit should only be used within the range of 5˚C - 35˚C
(41˚F - 95˚F).
Warning:
The voltage used must be the same as that specified on this unit. Us-
ing this product with a higher voltage other than that which is speci-
fied is dangerous and may result in a fire or other type of accident
causing damage. SHARP will not be held responsible for any dam-
age resulting from use of this unit with a voltage other than that which
is specified.
 Volume control
The sound level at a given volume setting depends on speaker effi-
ciency, location, and various other factors. It is advisable to avoid ex-
posure to high volume levels. Do not turn the volume on to full at
switch on and listen to music at moderate levels.
 Use the unit on a firm, level surface free from
vibration.
 Keep the unit away from direct sunlight,
strong magnetic fields, excessive dust,
humidity and electronic/electrical equip-
ment (home computers, facsimiles, etc.)
which generate electrical noise.
 In case of an electrical storm, unplug the
unit for safety.
 Hold the AC power lead by the head when
removing it from the wall socket, as pulling
the lead can damage internal wires.
 The AC power lead is used as disconnect
device and shall always remain readily
operable.
 Do not remove the outer cover, as
this may result in electric shock. Re-
fer internal service to your local
SHARP service facility.
 The ventilation should not be impeded by
covering the ventilation openings with
items, such as newspapers, tablecloths,
curtains, etc.

Preparation for Use
Operation with AC power
Check the setting of the AC voltage selector located on the rear
panel before plugging the unit into a wall socket. If necessary,
adjust the selector to correspond the AC power voltage used in
your area.
AC plug adaptor:
In areas (or countries) where a wall socket as shown in illustration 2
is used, connect the unit using the AC plug adaptor supplied with the
unit, as illustrated. The AC plug adaptor is not included in areas
where the wall socket and AC power plug can be directly connected
(see illustration 1 ).
Notes:
 If the unit will not be used for a long period of time, remove the AC
power lead from the wall socket.
 Connection of the AC power lead to the unit disconnects the
batteries.
 Use only the supplied AC power lead. Using other power leads
may cause an electric shock or fire.
Operation with batteries
Battery replacement:
Replace the batteries when they become weak and/or recording or
playback is impaired. This may occur even though radio broadcasts
are audible.
Notes:
 Replace all old batteries with new ones at the same time.
 Do not mix old and new batteries.
 Remove the batteries if they are weak or if the unit will not be
used for long periods of time. This will prevent potential damage
due to battery leakage.
 Batteries are not included.
Caution:
Do not use rechargeable batteries (nickel-cadmium battery, etc.).

Listening to a CD or MP3/WMA
disc
This system can play back a standard CD, CD-R/RW in the CD format

for MPEG Audio Layer 3.
MP3 is a type of audio code which is processed by significant
compression from the original audio source with very little loss
in sound quality.
 This system supports MPEG 1 Layer 3, MPEG 2 Layer 3, and
VBR files.
 Bitrate which is supported by MP3 is 32 ~ 320 kbps.

information on an MP3 or WMA disc.
 Bitrate which is supported by WMA is 64 ~ 160 kbps.
