Important Information about the Batteries
Never use the batteries for any purpose other than that for which they were intended. Never use a
battery which is damaged or worn out.
Heat or cold reduces the performance and service life of the batteries. A handset with hot or cold
batteries may be temporarily out of order even if the batteries are fully charged.
Used batteries should be disposed of in accordance with local authority regulations. Please hand
them in for recycling if possible.
Do not throw batteries in a fire.
Charging and Discharging
The batteries can be charged and discharged hundreds of times, but sooner or later they will be
worn out. If the operating time (i.e., talk and standby time) is significantly shorter than usual, then
it is time to replace the batteries.
To maintain the highest operating time possible, the batteries should be discharged now and again
by not placing the handset in the charger cradle but leaving it switched on until it discharges itself.
Only use this method to discharge the batteries.
Extreme temperatures influence the charging capability of the batteries.
Initial Setup and Operation
Charge the batteries approximately six to seven hours before using the handset for the first time.
This protective measure will extend the service life of the batteries.
The maximum capacity is only attained after three to five charging and discharging cycles.
Place the handset regularly in the charger cradle, thus ensuring optimum charging of the batteries.
When replacing the batteries, please pay attention to the correct polarity. It is essential to make sure
that only battery types approved by the manufacturer are used.
The manufacturer does not accept any liability for malfunctions or damage caused by using normal
batteries or other types of rechargeable batteries.
Your handset is only operational after the batteries have been charged. You can then use the hand-
set to make and receive calls.
