NOTE:
³ Note that a new battery's full performance is
achieved only after two or three complete charge
and discharge cycles!
· Standby time will be reduced by approximately
1 hour for every 6 minutes of talk time.
» The battery can be charged and discharged hun-
dreds of times but it will eventually wear out.
When the operating time (talk-time and standby
time) is noticeably shorter than normal, it is time to
buy a new battery.
¿ Use only batteries approved by the phone manu-
facturer 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 overcharg-
ing may shorten its life. If left unused a fully
charged battery will discharge itself in about a
week at room temperature.
´ For good operation times, discharge the battery
from time to time by leaving your phone switched
on until it turns itself off (or by using the battery
discharge facility of any approved accessory
available for your phone). Do not attempt to
discharge the battery by any other means.
