93RQT8857Progressive/InterlaceThe PAL video signal standard has 625 (or 576) interlaced (i) scanlines, whereas progressive scanning, called 625p (or 576p), usestwice the number of scan lines. For the NTSC standard, these arecalled 525i (or 480i) and 525p (or 480p) respectively.Using progressive output, you can enjoy the high-resolution videorecorded on media such as DVD-Video.Your television must be compatible to enjoy progressive video.Panasonic televisions with 625 (576)/50i · 50p, 525 (480)/60i · 60pinput terminals are progressive compatible.ProtectionYou can prevent accidental erasure by setting writing protection orerasure protection.RGBThis refers to the three primary colours of light, red (R), green(G), and blue (B) and also the method of producing video thatuses them. By dividing the video signal into the three colours fortransmission, noise is reduced for even higher quality images.Sampling frequencySampling is the process of converting the heights of sound wave(analog signal) samples taken at set periods into digits (digitalencoding). Sampling frequency is the number of samples taken persecond, so larger numbers mean more faithful reproduction of theoriginal sound.Signal QualityThis is the guide for checking the aerial direction. The numberedvalues displayed do not indicate the strength of the signal, butthe quality of the signal (the signal to noise ratio, or “S/N”). Thechannels you can receive are affected by weather conditions,seasons, time (day/night), region, length of the cable that isconnected to the aerial, etc.ThumbnailThis refers to a miniature representation of a picture used todisplay multiple pictures in the form of a matrix.1080iIn one high-defi nition image, 1080 (1125) alternating scan linespass every 1/50th of a second to create an interlace image.Because 1080i (1125i) more than doubles current televisionbroadcasts of 480i (525i), the detail is much clearer and creates amore realistic and rich image.1080pIn one high-defi nition image, 1080 (1125) scan lines pass at thesame time every 1/50th of a second to create a progressive image.Since progressive video does not alternate scan lines like interlace,there is a minimal amount of screen fl icker.720pIn one high-defi nition image, 720 (750) scan lines pass at the sametime every 1/50th of a second to create a progressive image. Sinceprogressive video does not alternate scan lines like interlace, thereis a minimal amount of screen fl icker.ReferencePlacementSet the unit up on an even surface away from direct sunlight,high temperatures, high humidity, and excessive vibration. Theseconditions can damage the cabinet and other components, therebyshortening the unit’s service life.Do not place heavy items on the unit.VoltageDo not use high voltage power sources. This can overload theunit and cause a fi re.Do not use a DC power source. Check the source carefully whensetting the unit up on a ship or other place where DC is used.AC mains lead protectionEnsure the AC mains lead is connected correctly and notdamaged. Poor connection and lead damage can cause fi re orelectric shock. Do not pull, bend, or place heavy items on the lead.Grasp the plug fi rmly when unplugging the lead. Pulling the ACmains lead can cause electric shock.Do not handle the plug with wet hands. This can cause electricshock.Foreign matterDo not let metal objects fall inside the unit. This can causeelectric shock or malfunction.Do not let liquids get into the unit. This can cause electric shockor malfunction. If this occurs, immediately disconnect the unit fromthe AC mains supply and contact your dealer.Do not spray insecticides onto or into the unit. They containfl ammable gases which can ignite if sprayed into the unit.ServiceDo not attempt to repair this unit by yourself.
