Replacing the Batteries58Caution:To reduce the risk of fire or injury to persons, read and follow these instructions.1. Use only the batteries specified.2. Do not use non-rechargeable batteries.3. Do not mix old and new batteries.4. Do not dispose of the batteries in a fire. They may explode. Check with local waste managementcodes for special disposal instructions.5. Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause burns orinjury to the eyes or skin. The electrolyte may be toxic if swallowed.6. Exercise care in handling the batteries in order not to short the batteries with conductive materialssuch as rings, bracelets, and keys. The batteries and/or conductor may overheat and cause burns.7. Charge the batteries provided with or identified for use with this product only in accordance with theinstructions and limitations specified in this manual.Important Notice Concerning the Correct Useand Charging of Ni-Cd (Ni-MH) BatteriesBatteries, due to their construction, undergo some wear and tear. The lifetime of a battery alsodepends on correct maintenance. Charging and discharging are the most important factors. Youshould take notice of the following to maintain the life of the battery as long as possible.Ni-Cd (Ni-MH) batteries have a kind of memory, the “memory effect”. If fully charged batteries areused several times only for 15 minutes in the handset and then recharged, the capacity of thebatteries will be reduced to 15 minutes due to the memory effect. Therefore you should dischargethe batteries completely, i.e. use them in the handset until “ ” on the display starts flashing.Then recharge them as described in the manual. After the memory effect has occurred, it ispossible to achieve almost complete capacity of the Ni-Cd (Ni-MH) batteries by charging anddischarging several times one after another.Ni-Cd (Ni-MH) batteries can also self-discharge. This self-discharge depends on the ambienttemperature. At temperatures under 0°C, the self-discharge will be the lowest. High humidity andhigh temperatures support the self-discharge. Also long-term storage will lead to self-discharge. Adead Ni-Cd (Ni-MH) battery should not be disposed of normally. They contain toxic heavycadmium (metal hydride) and therefore should be recycled.KX-TCD961CXB(57~68) 99.12.3 2:22 PM Page 58
