to the operating situations of your camcorder. To use the battery pack effectively • Battery pack performance decreases when the ambient temperature is 10 °C (50 °F) or below, and the length of time you can use the battery pack becomes shorter. In that case, do one of the following to use the battery pack for a longer time. - Put the battery pack in a pocket to warm it up, and install it in your camcorder right before you start taking shots. • Make sure to turn off the camcorder when you are not recording or playing back. The battery pack is also consumed when your camcorder is in recording standby or playback pause. • Have spare battery packs ready for 2 or 3 times the expected recording time, and make trial recordings before making the actual recording. • Do not expose the battery pack to water. The battery pack is not water resistant. About the remaining battery indicator • Check the level with the following indicators and % displayed on the LCD screen. Battery remaining indicator % 81% to 100% 51% to 80% 21% to 50% 1% to 20% - • The displayed level may not be correct under certain circumstances. • When the power goes off even though the remaining battery percent indicator indicates that the battery pack has enough power to operate, charge the battery pack fully again. Remaining battery percent will be indicated correctly. Note, however, that the battery indication will not be restored if it is used in high temperatures for a long time, or if left in a fully charged state, or when the battery pack is frequently used. Use the remaining battery percent indication as a rough guide only. About storage of the battery pack • If the battery pack is not used for a long time, fully charge the battery pack and use it up on your camcorder once a year to maintain proper function. To store the battery pack, remove it from your camcorder and put it in a dry, cool place. • To discharge the battery pack on your camcorder completely, leave your camcorder in recording standby until the power goes off. About battery life • The battery has a limited lifespan. Battery capacity decreases over time and through repeated use. If decreased usage time between charges becomes significant, it is probably time to replace it with a new one. • Each battery's life is governed by storage, operating and environmental conditions. About charging the battery pack • Use the AC Adaptor (supplied) to charge the designated batteries only. If you charge other types of batteries, those batteries may leak, heat up, burst, or give an electric shock, resulting in burns or injury. • Remove the charged battery from the AC Adaptor. • The CHG lamp of the supplied AC Adaptor flashes in 2 patterns as follows: Fast-flashing: Turns on and off rapidly at about 0.15-second intervals. Slow-flashing: Turns on and off alternately for about 1.5 seconds, and turns off completely for about 1.5 seconds. The lamp repeats this sequence. • If the CHG lamp is fast-flashing, remove the battery that is being charged, and then re-attach the same battery again firmly. If the CHG lamp continues fast-flashing, the cause could be that the battery is damaged, or the battery is not a designated type. Check the battery to confirm whether it is a designated type or not. If it is a designated type, remove the battery first, and then attach a brand-new battery or another known-to-be-good battery to see if the AC Adaptor is working correctly. If the AC Adaptor is working correctly, the cause could be that the battery is damaged. • If the CHG lamp is slow-flashing, the AC Adaptor is in standby mode and charging is suspended.
