Safety precautions
Gigaset SL750H PRO / HSG INT en / A31008-M2752-R121-1-7619 / security.fm / 7/9/15
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 www.gigasetpro.com in the Support category. We thereby help to save
paper while providing fast access to the complete up-to-date documentation at any time.
Use only the power adapter indicated on the device.
Use only rechargeable batteries that correspond to the specification (see "Specifications"). 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.
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 specifications of your Gigaset product see "Specifications").
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.
Your Gigaset is compatible with the majority of digital hearing aids on the market. However, perfect
function with all hearing aids cannot be guaranteed.
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.
The devices are not splashproof. For this reason do not install them in a damp environment such as
bathrooms or shower rooms.
Do not use the devices in environments with a potential explosion hazard (e.g. paint shops).
If you give your Gigaset to a third party, make sure you also give them the user guide.
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.
Emergency numbers cannot be dialled if the keypad/display lock is activated!

Gigaset SL750H PRO / HSG INT en / A31008-M2752-R121-1-7619 / netservices.fm / 7/9/15
Network services
Network services depend on the network provider (service provider) and must be requested
from that provider.
Network services fall into two distinct groups:
•Network services that are activated when in idle status for the following call or all subsequent
calls (for example, "calling anonymously"). These are activated/deactivated via the
Select Services menu.
•Network services that are activated during an external call, (for example,"consultation call",
"swapping between two callers" and "setting up conference calls"). These are made available
during an external call either as an option or by using a display key (e.g. Ext. Call,
Conference).
You will find a description of the features on your network provider's website or at one of their
store branches.
If you require assistance, please contact your network provider.
Calling Line Identification
During a call, the caller's number is transferred (CLI = Calling Line Identification) and may be
displayed on the recipient's display (CLIP = CLI presentation). If the caller's number is withheld,
it will not be displayed to the recipient. The call is made anonymously (CLIR = CLI Restriction).
Caller display for incoming calls
Calling Line Identification
The caller's phone number is displayed. If the caller's number is saved in the directory, the name

To activate/deactivate the features, a code is sent to the telephone network.
