Even if the battery supplied with the unit is not used, you should charge it at least once every three months because of the special quality of this battery. ÖThe rechargeable battery can be charged approximately 300 times. ÖDo not use any battery other than that specified. Use of other batter- ies maycause malfunctions. ÖWhen the operating time is reduced to about half the normal amount of time, even after a full charge is per- formed, replace the battery with a new one. ÖWhen charging or when using the rechargeable battery, use it within an ambient temperature range of 5˚C to 35˚C. ÖIf the rechargeable battery is used in a cold environment, the operating time will decrease.Since the rechargeable battery is vulnerable to damage, please note the following. ÖDo not carry the battery in your pocket or a bag together with metal objects (keys, coins, jewelry, etc.). The battery may short out and gen- erate significant amounts of heat. ÖDo not short-circuit the terminals as they will become very hot and will damage the battery. ÖDo not dip the battery in water, do not dispose of it in a fire, and do not take it apart. To avoid damaging the battery and shortening its service life, please note the following. ÖDo not drop or subject the battery to shock. ÖDo not insert objects (metal etc.) into the battery compartment of this product or into the rechargeable bat- tery. Do not get the terminals dirty. If the rechargeable terminals are dirty, the operating time may be shortened or it may not be possible to charge the battery. ÖAfter the rechargeable battery is charged or used, it will get slightly warm. This is normal. 7 Notes about the rechargeable battery DMC-J7R(K) COVER1,1P( 98.11.30 1:44 PM y[W 6
