Maintenance and precautions About the AVCHD format What is the AVCHD format? The AVCHD format is a high definition digital video camera format used to record a high definition (HD) signal of either the 1080i specification*1 or the 720p specification*2 using efficient data compression coding technology. The MPEG-4 AVC/H.264 format is adopted to compress video data, and the Dolby Digital or Linear PCM system is used to compress audio data. The MPEG-4 AVC/H.264 format is capable of compressing images at higher efficiency than that of the conventional image compressing format. The MPEG-4 AVC/ H.264 format enables a high definition video signal shot on a digital video camera recorder to be recorded on 8 cm DVD discs, hard disk drive, flash memory, memory card, etc. Recording and playback on your camcorder Based on the AVCHD format, your camcorder records with the high definition image quality (HD) mentioned below. In addition to high definition image quality (HD), your camcorder is capable of recording a standard definition (STD) signal in the conventional MPEG-2 format. Video signal*3: MPEG-4 AVC/H.264 1920 1080/60i, 1440 1080/60i Audio signal: Dolby Digital 2ch Recording media: Internal memory, memory card *1 1080i specification A high definition specification which utilizes 1,080 effective scanning lines and the interlace system.

About the memory card A memory card formatted by a computer (Windows OS/Mac OS) does not have guaranteed compatibility with your camcorder. Data read/write speed may vary depending on the combination of the memory card and memory card compliant product you use. Damaged or lost data may occur in the following cases (the data will not be compensated for): If you eject the memory card, or turn off your camcorder while your camcorder is reading or writing image files on the memory card (while the access lamp is lit or flashing) If you use the memory card near magnets or magnetic fields It is recommended that you make a back-up of important data on the hard disk of a computer. Do not attach a label or the like on memory card or memory card adaptor. Do not touch, or allow metallic objects to come into contact with the terminals. Do not bend, drop or apply strong force to the memory card. Do not disassemble or modify the memory card. Do not let the memory card get wet. Keep the memory card out of the reach of small children. There is danger that a child might swallow it. Do not insert anything other than the compliant size of memory card into the memory card slot. Doing so may cause a malfunction. Do not use or keep the memory card in the following locations: Places subject to extremely high temperature, such as a car parked outside in the summer Places under direct sunlight Places with extremely high humidity or subject to corrosive gases
