The following program is available in the United States. Please consult local environmental authorities concerning the availability of this or other programs in your area.
The RBRCTM Seal SHARP participates in the RBRCTM* Nickel-Cadmium Battery Recycling Program in the United States. The RBRCTM Seal on our battery pack contained in our product indicates that SHARP is voluntarily participating in an industry program to collect and recycle these batteries. The RBRCTM program provides you with a convenient alternative to placing spent Nickel-Cadmium battery packs into the trash or municipal waste stream, which is illegal in some areas. At the end of their useful life, the Nickel-Cadmium battery can be dropped off at the nearest collection center for recycling. For information on the nearest collection center, call 1-800-8-BATTERY or your local recycling center. If you are located outside the United States, contact your local authorities for information concerning proper disposal and/or recycling of this battery. SHARP's involvement in this program is part of our commitent to protecting our environment and conserving natural resources. [Footnote] *RBRC

2. FEATURES
7" LCD Screen and Stereo Speakers
• A big 7" LCD screen and built-in stereo speakers provide exciting DVD viewing, even without connecting to a TV.
• Dolby Virtual provides high-quality surround sound.
2-WAY Power Supply (Battery pack is sold separately.)
• A 2-way power supply allows operation using the supplied AC adapter for indoor play, or the battery pack sold separately for outdoor play.
Compact, Lightweight Design
• About the size of a movie DVD case, your DVD player is designed to go along just about anywhere.
High-Resolution Images, High-Quality Sound
• A high-resolution 336,960-pixel LCD screen produces images of outstanding quality.
• Digital gamma correction and digital super picture provide more realistic image detail.
• Dolby Virtual ensures richer sound from two built-in speakers.
AV input/output, optical digital output jack equipped as standard
• An optical digital output jack (which doubles as the audio input/output jack) can be used to output a stream of *1Dolby Digital 5.1 channel audio, *2DTS digital audio and Audio MPEG. Connecting a Dolby Digital/DTS/Audio MPEG digital surround processor or amplifier to this jack creates an environment of amazingly powerful surround sound.
• The AV input/output jack can be used to connect a video deck or camcorder to your DVD player. Or you can use these jacks to connect to a TV for big-screen viewing. (Output only is supported for S-video. An S-video signal cannot be input to your DVD player.)

Word selection address: Selection of one word of 16k byte block. These addresses
Block selection address: Selection of 1/32 erase block. These addresses are latched
High order byte data input/output: The function is the same as that of low order byte
Chip enable: Device control logic, input buffer, decoder and sense amp. are activated. Chip becomes active only when CE# is “Low”. Reset/Pow er down: If RP# is set to “Low”, the control circuit is initialized when power is turned on. Hence , the RP#pin is set to “Low”. When power is turned on or off or in case of fluctuation it is kept at “Low” so as to protect data from noise . When RP# is in “Low” state, the de vice is in deep po wer do wn state. 480 ns is required to recover from the deep power do wn state. If the RP# pin becomes “Low”, the whole chip operation is interrupted and reset. After reco very the device is set to arr a y read state. Output enable: When OE# is set to “Low”, data is output from the DQ pin. When OE# is set to “High”, the DQ pin is set to float state. Write enable: Command user interface, data Q register and address Q latch access
are fetched. Ready/busy: The state of internal write state machine is output. In “Low” state it is indicated that the write state machine is in operation. If the write state machine w aits for next operation instruction, erase is suspended or it is in deep power do wn state , the RY/ BY# pin is in float state. Byte enable: When BYTE# is set to “Low”, the device is set to the x8 mode . At this time the DQ
-DQ15 pin becomes float state. Address A-1 selects high order/low order
