Facilidade de uso
If the surfaces are extremely dirty, use a soft cloth lightly moistened with a mild detergent solution. Do not use strong solvents, such as alcohol, benzine, or thinner, as these might damage the surface of the unit. To obtain a clear picture The DVD player is a high-tech, precision device. If the optical pick-up lens and disc drive parts are dirty or worn down, the picture quality will be poor. Regular inspection and maintenance are recommended after every 1,000 hours of use. (This depends on the operating environment.) For details, please contact your Aiwa dealer. INTRODUCTION En CONTINUE CONTINUE ENGLISH 7 Before Use (continued) Cleaning discs Remote control Fingerprints and dust on the disc can cause poor picture quality and sound distortion. Before playing, clean the disc with a clean cloth. Wipe the disc from the center out. Do not use strong solvents such as alcohol, benzine, thinner, commercially available cleaners, or anti-static spray intended for analog records. Storing discs After playing, store the disc in its case. Do not expose the disc to direct sunlight or sources of heat, or leave it in a parked car exposed to direct sunlight, as there may be a considerable temperature increase inside the car. Notes on copyright It is forbidden by law to copy, broadcast, show, broadcast via cable, play in public, or rent copyright material without permission. This product features the copy protection function developed by Macrovision. Copy protection signals are recorded on some discs. When recording and playing the pictures of these discs on a VCR, the picture noise will appear. This product incorporates copyright protection technology that is protected by method claims of certain U.S. patents and other intellectual property rights owned by Macrovision Corporation and other rights owners. Use of this copyright protection technology must be authorized by Macrovision Corporation, and is intended for home and other limited viewing uses only unless otherwise authorized by Macrovision Corporation. Reverse engineering or disassembly is prohibited. Installing batteries Detach the battery cover on the rear of the remote control, and insert two LR03 (size AAA) batteries with 0and 9 aligned correctly. LR03 (AAA) When to replace the batteries The maximum operating distance between the remote control and the sensor of the unit is approximately 7 meters (23 feet). If the operating range decreases, replace the batteries with new ones. NOTES •When operating with the remote control, point the top of the remote control toward the DVD player. • If the unit is not going to be used for an extended period of time, remove the batteries to prevent possible electrolyte leakage. • The remote control may not operate correctly when: -There is an intense light, such as sunlight, in the line of sight between the remote control and the DVD player. -There is fluorescent lighting near the remote sensor in the display window of the unit. -Other remote controls are used nearby (those of a TV, etc.). 8 ENGLISH General information on progressive scan General information on progressive scan This unit includes a progressive scan conversion circuit. This generates high-resolution progressive scan video, with a lower flicker rate, allowing you to see the movie at its original quality. What is a progressive scan? The conventional television system has 525 scan lines making up a frame, but these are scanned in alternate interlaced passes of the 262.5 odd scan lines and the 262.5 even scan lines (in the case of the NTSC color system). Since its frame rate is 30 frames per second, one of these passes, termed a field, occurs every 1/60 second. With larger screens, since the whole screen is only refreshed every 1/30 second, there can be noticeable flickers. In distinction to this, a progressive scan is one where all of the lines are scanned successively in a single pass. By saving a field in memory, it is possible to convert an interlaced video signal to a progressive scan, which then allows the image to be refreshed every 1/60 second, reducing flickers on a large screen. Conventional interlaced scan (525 lines) Progressive scan INTRODUCTION 262.5 lines 525 lines Scan of one field (1/60 second) Advantages of progressive scan conversion in the DVD player Since the DVD player converts the video signal to a progressive scan before digital-analog conversion, the total number of conversions the signal undergoes is reduced, compared with using a progressive scan conversion in the television (see following figure). This reduces signal degradation, and allows higher quality video playback.
