Precautions during use

• The battery is only designed for use with this handset.
• Only use the charging point supplied to charge the battery.
• New batteries are not charged up. Therefore you must charge the battery before using it for the
first time.
• The use of the battery in a cold environment can shorten the expected battery life of a fully
loaded battery. Charge the battery in a place where the temperature is in the region of 10°C to
35°C. Charging in a place outside of this temperature area can lead to charging time being
longer than normal, or could even lead to failure of the charging process.
• A very limited battery life after full charging indicates that the operational life of the battery has
expired. Replace the battery (complete with the battery compartment cover) with a new one.
• Never wipe the battery with thinners, petroleum ether, alcohol or other liquid products, or with
chemically treated wipes. This can lead to deformation of the battery, and to operational fail-
ure.

Initial operation

Charge the battery for approx. 4 to 6 hours before using your handset for the first time. The protec-
tive measure serves to extend the operational life of the battery.
Maximum battery power will first be reached after three to five cycles of charging and running
down.
Regularly place the handset on the charging point to achieve optimum battery charging.
Your handset will only be ready for use after the battery has been charged for the first time. Only
then can calls be received and/or made from this handset.
