Base
Your handset is registered with a N870 IP
PRO Multicell System, that can comprise
many base stations. When you move
around with your handset within range
of the multi-cell system, the handset
automatically connects to the base
station having the best connection
(roaming). You can also move around
freely during a call without the connec-
tion being interrupted (handover).

tion of base stations, and on registering a
handset with a multi-cell system:

Safety precautions
Read the safety precautions and the user guide before use.
Comprehensive user guides for all telephones and telephone systems as well as for
accessories can be found online at gigaset.com/pro in the Support category. We
thereby help to save paper while providing fast access to the complete up-to-date
documentation at any time.
The device cannot be used in the event of a power failure. In case of a power failure it
is also not possible to make emergency calls.
Emergency numbers cannot be dialled if the keypad/display lock is activated!
Use only rechargeable batteries that correspond to the specification (see list of
permitted batteries www.gigaset.com/service). Never use a conventional (non-
rechargeable) battery or other battery types as this could result in significant health
risks and personal injury. Rechargeable batteries, which are noticeably damaged,
must be replaced.
The handset must not be operated if the battery cover is open.
Ensure that the batteries can not be short-circuited by objects in the battery compart-
ment
Do not use the devices in environments with a potential explosion hazard
(e.g. paint shops).
The devices are not splashproof. For this reason do not install them in a damp environ-
ment such as bathrooms or shower rooms.
Use only the power adapter indicated on the device.
Whilst charging, the power socket must be easily accessible.
Remove faulty devices from use or have them repaired by our Service team, as these
could interfere with other wireless services.
Do not use the device if the display is cracked or broken. Broken glass or plastic can
cause injury to hands and face. Send the device to our Service department to be
repaired.
Keep small cells and batteries, which can be swallowed, out of the reach of children.
Swallowing a battery can lead to burns, perforation of soft tissue and death. Severe
burns can occur within 2 hours of swallowing.
In the case of a swallowed cell or battery, seek medical care immediately.

Safety precautions
7
Using your telephone may affect nearby medical equipment. Be aware of the tech-
nical conditions in your particular environment, e.g. doctor's surgery. If you use a
medical device (e.g. a pacemaker), please contact the device manufacturer. They will
be able to advise you regarding the susceptibility of the device to external sources of
high frequency energy (for the specifications of your Gigaset product see "Technical
data").
If a USB adapter cable is included, only use a USB power supply (5Volt) with USB-A
connection. The use of other voltage sources e.g. PC's with USB connection can cause
damage.
If a plug-in power supply is included, please use this power supply.
