Safety precautions
Safety precautions
Read the safety precautions and the user guide before use.
Explain their content and the potential hazards associated with using the device to
your children.
The device cannot be used in the event of a power failure. It is also not possible to trans-
mit emergency calls.
Emergency numbers cannot be dialled if the keypad/display lock is activated!
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.
Use only the cables supplied for fixed line and LAN connection and connect these to the
intended ports only.
Use only rechargeable batteries that correspond to the specification (see "Technical
data"). 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.
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.
Do not hold the rear of the handset to your ear when it is ringing or when speaker mode
is activated. Otherwise you risk serious and permanent damage to your hearing.
The phone may cause interference in analogue hearing aids (humming or whistling) or
cause them to overload. If you require assistance, please contact the hearing aid supplier.
Using your telephone may affect nearby medical equipment. Be aware of the technical
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 Technical data of your Gigaset product see
"Technical data").
