Special Notes

" " " " " US and foreign patents licensed from Dolby Laboratories. The AC adaptor supplied with the MD-DR470H must not be used with other equipment. When recording important selections, make a preliminary test to ensure that the desired material is properly recorded. SHARP is not liable for damage or loss of your recording arising from malfunction of this unit. The letters in brackets contained in the model number indicate the colour of the product only. Operation and specifications are unaffected.

Features

! A Portable MD player with "Mobile 1-bit digital amplifier"
" The 1-bit digital signal is sent to a constant voltage circuit directly from a high-order modulation circuit. The amplifier transmits and amplifies the signal, and allows extremely natural and clear sound with little deterioration. " High-quality sound is achieved by vast improvements in the sound resolution. The speed and the smoothness of rise of the sound are consequently ensured.
! "4-pole plug headphone" optimizes "Mobile 1-bit digital amplifier"
" SHARP has adopted "4-pole plug" headphones and a remote control that completely separate right and left sound. Enjoy the high quality sound of the "Mobile 1bit digital amplifier".

! About ATRAC

The ATRAC (Adaptive TRansform Acoustic Coding) system compresses the sound data into 1/5 by cutting out the inaudible sound. Since the sound is selected based on psychoacoustics masking, the sound quality is not impaired. This unit is equipped with the ATRAC3 compressing system that can reduce the sound data to 1/10 or 1/20 of its original size. By employing this system, 2 times and 4 times long recordings are enabled in stereo mode.

What is a MiniDisc for stamping?

Other Features and Caution

! Resuming auto play

When you stop playback and replay the MiniDisc without removing it, playback starts from the point you stopped it.

! Rechargeable battery

" A rechargeable nickel-metal hydride battery is the only kind that can be used. Even if the battery is not used, you should charge it at least once every three months because of the special quality of this battery. " The rechargeable battery can be charged approximately 300 times. " 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 (ADN55BT). " When the battery is charged for the first time or is charged after not being used for a long period, the operating time may be shorter than normal. The battery life will recover with normal use i.e. charging and discharging. " To avoid shortening the service life of the battery only recharge the battery after it is completely discharged. " If the rechargeable battery is used in a cold environment, the operating time will be reduced. " Do not carry the battery in your pocket or a bag together with metal objects (keys, coins, jewelry, etc.). The battery may short out and generate significant amounts of heat. " Do not short-circuit the terminals as they will become very hot and will damage the battery. " Do not drop or subject the battery to shock. " Do not insert objects (metal etc.) into the battery compartment of this product or into the rechargeable battery.
-Other Features and Caution-
Once you remove the MiniDisc, playback starts from the first track.

The continuous recording time is for analogue inputs when the volume level is set to "VOL 0". The continuous play time shows the value when the volume level is set to "VOL 15". The above values are the standard values when the unit is charged and used at an ambient temperature of 25C (77F). The operating time when using an alkaline battery may be different, depending on the type and manufacturer of the battery, and on the operating temperature. " The setting for the REMOTE LCD is set to "AUTO OFF" (page 55).
