2.3.1 Charging and Discharging
The battery can be charged and discharged hundreds of times, but it will even-
tually be used up. When the operating time (i. e. talk and stand-by time) has
become noticeably shorter than normal, the battery should be replaced.
In order to achieve long operating times, you should discharge the battery at
intervals by not placing the handset in the charging station and leaving it
switched on until it switches itself off. Only use this method to discharge the
battery.
Extreme fluctuations in temperature have an effect on the charging capacity of
the battery.
2.4 Charging the Battery
2.4.1 Commissioning
Charge the batteries for approx. five to six hours before using your handset for the
first time. This safety measure extends the lifetime of your batteries. The maximum
performance of the batteries is only reached after three to five charging/dis-
charging cycles.
Place the handset in the charging station regularly in order to reach the optimum
battery charge.
Be careful to observe the correct polarity when replacing the batteries. It is abso-
lutely essential that you only use rechargeable batteries authorised by the manu-
facturer. The manufacturer does not accept any responsibility for malfunction or
damage when other types of rechargeable battery or normal batteries are used.
