Charging and discharging the battery
• Your phone is powered by a rechargeable battery.
• Note that a new battery's full performance is achieved only after two or three complete charge and
discharge cycles!
• The battery can be charged and discharged hundreds of times but it will eventually wear out. When
the operating time (talk time and stand-by time) is noticeably shorter than normal, it is time to buy
a new battery.
• Use only batteries approved by the phone manufacturer and recharge your battery only with the
chargers approved by the manufacturer.
• When a charger is not in use, disconnect it from the power source. Do not leave the battery
connected to a charger for longer than a week, since overcharging may shorten its life. If left
unused a fully charged battery will discharge itself over time.
• For good operation times, discharge the NiMH battery from time to time by leaving your phone
switched on until it turns itself off. Do not attempt to discharge the battery by any other means.
• Temperature extremes will affect the ability of your battery to charge: allow it to cool down or
warm up first.
• When the battery is running out of power and only few minutes of talk time remain, a warning tone
is heard and Battery low is briefly displayed. When no more talk time is left, Battery empty is
displayed and a warning tone is sounded and the phone switches itself off.
