PRECAUTIONS FOR THE BATTERY PACK When a fully charged battery pack is attached, the approximate continuous operating time is as shown in the table on the left. ● Battery operating time may differ depending on the number of times the battery has been charged, charging conditions and the operating environment, etc. Regard the values in the table on the left as approximate reference times. ● Operating time is reduced in areas with a cold environment. ● Operating time is reduced when the power zoom lens is used frequently and when start/stop of recording is performed frequently. ● When the battery pack is not in use, it must be stored in a cool, dry place. Do not leave the battery pack in a place where it might be subject to high temperatures (under direct sunlight in a car, etc.), as this could cause battery leakage or shorten the service life. ● When the terminal section of the battery pack gets dirty, the operating time will be shortened. ● If the operating time becomes greatly reduced even immediately after recharging, the service life of the battery pack is nearly finished. Purchase a new battery pack. Recharging ● Recharge the battery pack after completely discharging it. Repeated recharging with residual charge remaining could result in reduced battery capacity. ● If the battery capacity is reduced by repeating incomplete recharging, or recharging without discharging, once discharge the battery pack completely, then recharge it to restore the battery capacity. ● If the battery pack is recharged with its internal temperature raised immediately after use, recharging may not be performed completely. 35
