and Charging the Batteries

Before using your handset, place it in the base sta­tion with the display facing upward. After about one
minute, the handset's internal number is shown in
upper left hand corner of display (for example, “1”).

For information on how to register additional
handsets (bought separately), see page 27.

Your Gigaset is now ready for operation. Please set
date and the time (see page 11), so that the time of
incoming calls can be noted correctly.

Press Keys:

Leave the handset for about 12–14 hours in the
base station to charge the batteries. The charging
status symbol flashes on the handset, indicating
that the batteries are being charged:

• Once the initial charging operation is com­pleted, replace your handset into the base
station after each call. Charging is con­trolled electronically. This ensures opti­mum charging and prolongs battery life.

• The batteries heat up during charging. This
is normal and not dangerous.

• The battery charging status is correctly dis­played only after uninterrupted charging/
discharging. You should therefore avoid
opening the battery compartment unnec­essarily.
