Extreme fluctuations in temperature have an effect on the charging capacity of the
battery.
Charging the Battery
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/discharging
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 absolutely
essential that you only use rechargeable batteries authorised by the manufacturer.
The manufacturer does not accept any responsibility for malfunction or damage
when other types of rechargeable battery or normal batteries are used.
