4 Charging the Batteries
Initial Setup
and Operation
Charge the batteries approximately 6 to 7 hours before initial
use of the handset. This protective measure extends the ser-
vice life of the batteries.
The maximum power output is only attained after three to five
charging and discharging cycles.
Place the handset regularly in the charger thus ensuring opti-
mum charging of the batteries.
When replacing the batteries, pay attention to the correct
polarity. It is essential to make sure that only battery types
approved by the manufacturer are used.
Use only rechargable AAA NiMh battery of 800 mAh, 1.2 V. The
manufacturer does not accept liability for malfunctions or dam-
age caused by using other battery types or normal batteries.
