If youconnect the compact power adapter to the camcorder while a battery pack is attached, the camcorder will drawpower from the power outlet.Attaching the Ferrite CoreAttach the enclosed ferrite core before you connect the compact power adapter to the camcorder. Attaching theferrite core to the compact power adapter cable is necessary to suppress RF interference.1 Attach the ferrite core to the cable about 6 cm (2.4 in.) from the DC plug(the plug to be connected to the DC IN terminal).2 Pass the cable through the center of the core and wrap it around the core(as shown in the illustration), then close the unit until it clicks shut.Charging a Battery PackYou can power the camcorder using the supplied BP-820 Battery Pack or the optional BP-828 Battery Pack.Both battery packs are compatible with Intelligent System so you can check the approximate remaining batteryusage time (in minutes) on the screen. For more accurate readings, when using a battery pack for the first time,charge it fully and then use the camcorder until the battery pack is completely depleted.1 Connect the compact power adapter to the camcorder and plug the power cord into a power outlet.2 Attach the battery pack to the camcorder.
