These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: q Reorient or relocate the receiving antenna. q Increase the separation between the equipment and receiver. q Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. q Consult the dealer or an experienced radio/TV technician for help.

PRECAUTIONS

s Important
q Do not wear your headphones when you are crossing streets or near traffic. q Do not use your headphones while driving a motor vehicle, it may create a dangerous traffic hazard and may be illegal. Remember to obey all of the safety rules in your area. q Do not play the unit at a high volume. Hearing experts advise against extended play at high volume levels. q If you experience ringing in your ears, reduce the volume or discontinue use.

s Storing the unit

Avoid using or leaving the unit in the following places. q Places exposed to direct sunlight for many hours (especially in cars with the doors and windows closed) or near heaters. (The cabinet may deform, change color, or malfunction.) q Places exposed to water. q Places exposed to excessive dust. q Places where temperatures are excessively high or low. q Places (bathrooms) where the humidity is extremely high. q Places with strong magnetic fields such as TVs or loudspeakers. q Places exposed to vibration. q Places where sand can easily enter the inside of the unit (beaches etc.). q If the unit is used near radio tuners or TVs, noise and/or picture interference may result. If you experience these problems, move the unit away from such devices.

s Volume setting

If the volume is adjusted according to your usual expectations of noise, you may damage your hearing due to the high volume. Reduce the volume before starting to play. MiniDiscs, compared to ordinary cassette tapes, have very little noise.
s Concern for others when listening to MiniDiscs
While listening to music, the sound escaping from your headphones may disturb people around you. If you are using the unit in particularly crowded places (such as on trains or buses), reduce the volume to avoid disturbing people around you.

s Precautions

To avoid accidental electric shock or other possible problems, observe the precautions listed below. q Do not disassemble or modify the unit. q Do not drop or subject the unit to shock. q Do not use the unit near open flames. q Do not spill liquid on the unit. q Do not use an external power supply, other than the 5V DC power supply packaged with this unit. q SHARP is not responsible for damage due to improper use. Refer all servicing to a SHARP authorized service center.
s Notes about the rechargeable battery
q A rechargeable lithium-ion battery is the only kind that can be used. Even if the battery supplied with the unit is not used, you should charge it at least once every three months to maintain the battery. q The rechargeable battery can be charged approximately 300 times. q Do not use any battery other than that specified. Use of other batteries may cause malfunctions. q When the operating time is reduced to about half the normal amount of time, even after a full charge is performed, replace the battery with a new one. q When charging or when using the rechargeable battery, use it within an ambient temperature range of 41F (5C) to 95F (35C). q If the rechargeable battery is used in a cold environment, the operating time will decrease.

No sound is heard from the headphones.
When the operation buttons are pressed, the unit does not respond. Some sounds are skipped. The MiniDisc cannot be ejected.
Recording and editing are impossible.

s If trouble occurs

When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction. If such a problem occurs, do the following: 1. Unplug the AC adaptor from the AC outlet. 2. Remove the battery. 3. Leave the unit completely unpowered for approximately 30 seconds. 4. Plug the AC adaptor back into the AC outlet and retry the operation. If strange sounds, smell or smoke come out of the unit or an object is dropped into the unit, remove the AC adaptor from the AC outlet immediately and contact an authorized Sharp service center.
MINIDISC SYSTEM LIMITATIONS
MiniDiscs are recorded using a different system than is used for cassette tapes or DAT recordings. Therefore, the following conditions may be encountered, depending on how the disc has been recorded or edited. These are due to system limitations, and should be considered normal. Even if the maximum recording time of a MiniDisc has not been reached, DISC FULL or TOC FULL may be displayed. When the number of tracks used reaches the limit, regardless of the remaining recording time, further recording will be impossible. (Maximum number of tracks: 254) If a MiniDisc has been recorded or edited repeatedly or if a MiniDisc has scratches on it, it may not be possible to record the maximum number of tracks on it. If there are scratches on a disc, the unit will automatically avoid recording in those areas. The recording time will be reduced. When the remaining recording time of a disc is displayed, short tracks less than 8 seconds long may not be included in the total. For MiniDiscs on which repeated recording and editing operations were performed, the COMBINE function may not work. A cluster (about 2 seconds) is normally the minimum unit of recording. So, even if a track is less than 2 seconds long, it will use about 2 seconds of space on the disc. Therefore, the time actually available for recording may be less than the remaining time displayed. If there are scratches on discs, those sections will be automatically avoided (no recording will be placed in those sections). Therefore, the recording time will be reduced. For MiniDiscs on which repeated recording and editing were performed, some sounds may be skipped while cueing and reviewing. If there are scratches or dust on a MiniDisc, the track numbers following that track will be increased by one.

Even if the number of tracks and the recording time have not reached the limit, DISC FULL may be displayed. Even if several short tracks are erased, the remaining recording time may not show an increase. Two tracks may not be combined in editing.
The total of the recorded time and time remaining on a disc may not add up to the maximum possible recording time.
When recorded tracks are played back using the cue and review operations, some sounds may be skipped. While recording, a track number may be created in the middle of a track.
