Gigaset SX790 ISDN – More than just a telephone
Your ISDN connection offers you two telephone lines simultaneously.
Your telephone sets new standards for the way you communicate at home.
The configuration and user interface of the cordless phone are excellent,
providing you with first-class voice quality in handsfree mode, while the USB port
offers you enormous flexibility.
The large TFT display, user-friendly keypad and clearly laid out menu are very sim-
ple to use.
Your phone can do a whole lot more:
uUse your Gigaset as a PABX and register up to six handsets. Assign each handset
its own phone number (MSN).
uIt is easy to configure your Gigaset thanks to the wizards: these determine the
MSNs for your ISDN connection (provider-specific) and assist you with assigning
send and receive MSNs to the handsets (¢page 16).
uYou can synchronise your directories on your telephone, mobile phone and PC
via the USB port using the Gigaset QuickSync software (¢page 83).
uYou can save appointments (¢page 57) and anniversaries, e.g., birthdays
(¢page 43), in your phone and it will remind you of them in advance.
uYou can designate important people as VIPs to identify important calls from the
ringtone (¢page 40).
uYou can assign a picture to entries in the directory – in future, the picture will
appear every time you receive a call from this number (¢page 40).
uIf you do not want to take calls where the caller has withheld their number, just
set your handset to only ring if Calling Line Identification has not been withheld
(¢page 68).
uIf you do not wish to be disturbed, you can simply set up a time control so that
your phone will only ring when it is convenient (¢page 67). VIP calls are still put
through.
uYou can assign important numbers to the number keys on your phone.
The number is then dialled by simply pressing a key (¢page 64).
uAdapt your Gigaset to suit your handsfree requirements (¢page 67) and adjust
the brightness of your keypad to suit you (¢page 66).
uView your personal pictures as a screensaver slide show (¢page 65).
uSet the display to the large font to increase legibility in particularly important
screens e.g., the directory and lists (¢page 65).
uGigaset Green Home – Be environmentally aware when using your phone.

Following safety precautions
Warning
Be sure to read this user guide and the safety precautions before using your telephone.
Explain their content and the potential hazards associated with using the telephone to your
children.
Use only the power adapter supplied, as indicated on the underside of the base.
Use only rechargeable batteries that correspond to the specification provided on
page 81, as this could otherwise result in significant health risks and personal injury.
Using your telephone may affect nearby medical equipment. Be aware of the tech-
nical conditions in your particular environment e.g., doctor's surgery.
Do not hold the rear of the handset to your ear when it is ringing or when handsfree
mode is activated. Otherwise, you risk serious and permanent damage to your hear-
ing.
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 handset may cause an unpleasant humming or whistling noise in hearing aids
or cause them to overload. If you require assistance, please contact your hearing aid
supplier.
Do not install the base or charger in bathrooms or shower rooms. The base and
charger are not splashproof (¢page 80).
Do not use your phone in environments with a potential explosion hazard
(e.g., paint shops).
If you give your phone to a third party, make sure you also give them the user guide.
Remove faulty bases from use or have them repaired by our Service team, as they
could interfere with other wireless services.
Please note
Not all functions described in this user guide are available in all countries or with all network
providers.

Version 4.1, 21.11.2007
Installing the base
The base is designed for use in closed, dry rooms with a temperature range of +5°C
to +45°C.
¤Set up the base at a central point in the building on a level, non-slip surface or
mount the base on the wall (¢page 87).
The phone's feet do not usually leave any marks on surfaces. However, due to the
multitude of different varnishes and polishes used on today's furnishings, the
occurrence of marks on the surfaces cannot be completely ruled out.
Please note:
uNever expose the telephone to the influence of heat sources, direct sunlight or
other electrical devices.
uProtect your Gigaset from moisture, dust, corrosive liquids and fumes.
Connecting the base
¤First, connect the
telephone jack 1
and insert the cables
into the cable ducts.
¤Then connect the
power adapter 2.
Please note:
uThe power adapter must always be connected, as the phone will not operate
without a mains connection.
uUse only the power adapter and phone cord supplied.
Please note
Pay attention to the range of the base.
This is up to 300 m in unobstructed outdoor areas and up to 50 m inside build-
ings. The range is reduced when Eco Mode is activated (¢page 56).

Setting up the handset for use
The display and keypad are protected by plastic films.
Remove the protective films!
Inserting the batteries and closing the battery cover
Warning
Use only rechargeable batteries (¢page 81) recommended by Gigaset Com-
munications GmbH i.e., never use a conventional (non-rechargeable) battery, as
this could result in significant health risks and personal injury. For example, the
outer casing of the batteries could be damaged or the batteries could explode.
The phone could also malfunction or be damaged as a result of using batteries
that are not of the recommended type.
¤Insert the batteries with
the polarity in the
correct direction.
The polarity is indicated
in/on the battery com-
partment.
¤First, align the protrusions
on the side of the battery
cover with the notches on
the inside of the casing.
¤Then press the cover until
it clicks into place.
To open the battery cover, for
instance to replace the batter-
ies, insert a coin into the cavity
on the left-hand side of the cas-
ing, then pull the battery cover
in an upward direction.

Attaching the belt clip
The handset has notches on each side to attach the belt clip.
¤To attach – press the belt clip
onto the back of the handset so

the clip and the housing and pull
the clip in an upward direction.
Placing the handset on the base
¤Place the handset in the base with its display facing forward.
Each handset is registered with the base at the factory. You do not need to register
the handset again. If you wish to use your handset with a different base or use addi-
tional handsets with your base, you have to register the handset manually
¢page 59.
To charge the batteries, leave the handset in the base.
Please note
The handset may only be placed in the base provided for it.

uAfter the first battery charge and discharge, you may replace your handset
in its base after every call.
uAlways repeat the charging and discharging procedure if you remove the
batteries from the handset and reinsert them.
uThe batteries may warm up during charging. This is not dangerous.
uAfter a while, the charge capacity of the batteries will decrease for technical
reasons.

Connection assistant
The connection assistant will start automatically as soon as the ISDN wizard is
complete. You can use the connection assistant to assign the previously configured
numbers to internal parties as send and receive connections, if necessary.
uReceive connections are numbers (MSNs) on which you can be called. You can
assign the MSNs for internal parties as the receive connection. Incoming calls are
only forwarded to the internal parties to which the relevant receive connection
has been assigned.
uSend connections are the numbers (MSNs) that are sent to the called party. The
network provider calculates charges based on the send connections. You can
assign a fixed MSN as a send connection to each internal party.
uEvery MSN can be both a send and receive connection. You can assign each MSN
to multiple handsets.
After registration/getting started, the handsets are assigned all MSNs as receive
connections. The base number (usually MSN1) is assigned to the devices as a send
connection.
¤Press the §Yes§ display key if you
wish to display or amend the send
and receive connection settings for
