Important Information474) Do not dispose of the batteries in a fire. They may explode. Check with local wastemanagement codes for special disposal instructions.5) Do not open or mutilate the batteries. Released electrolyte is corrosive and maycause burns or injury 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 withconductive materials such as rings, bracelets, and keys. The batteries and/orconductor may overheat and cause burns.7) Charge the batteries provided with or identified for use with this product only inaccordance with the instructions and limitations specified in this manual.Important Notice Concerning the Correct Use and Charging of Ni-MHBatteriesBatteries, due to their construction, undergo some wear and tear. The lifetime of a batteryalso depends on correct maintenance. Charging and discharging are the most importantfactors. You should take notice of the following to maintain the life of the battery as longas possible.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 ofthe batteries will be reduced to 15 minutes due to the memory effect. Therefore youshould discharge the batteries completely, i.e. use them in the handset until “ ” on thedisplay starts flashing. Then recharge them as described in the manual. After thememory effect has occurred, it is possible to achieve almost complete capacity of the Ni-MH batteries by charging and discharging several times one after another.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. Highhumidity and high temperatures support the self-discharge. Also long-term storage willlead to self-discharge. A dead Ni-MH battery should not be disposed of normally. Theycontain toxic heavy metal hydride and therefore should be recycled.Safety InstructionsPay special attention to the safety suggestions listed below.Safety1) Power source: The AC adaptor should be connected to a power supply only of thetype as marked on the AC adaptor. The AC adaptor is used as the main disconnectdevice, ensure that the AC outlet is located/installed near the unit and is easilyaccessible.2) Non use periods: When the PS is not being used, turn the power off. When leftunused for a long period of time, the charger should be unplugged from the AC outlet.3) Do not place metal items such as coins or rings on the charger. As they become hot,you might get burned if you touch them.
