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 51, 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 speaker
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 interference in analog hearing aids. If you require assistance,
please contact the hearing aid supplier.
Do not install the base or charger in bathrooms or shower rooms. The base and
charger are not splashproof (¢page 51).
Do not use your phone 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 bases from use, as these could interfere with other wireless services.
Please note
uNot all of the functions described in this user guide are available in all countries.
uThe device cannot be used in the event of a power failure. In case of a power failure, it is
not possible to make any calls including emergency calls.

Setting up the base and charger (if included)
The base and charger are designed for use in dry rooms in a temperature range of
+41°F to +113°F.
¤Set up the base at a central point in the building on a level, non-slip surface or
mount the base or charger on the wall (¢page 62).
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 2
and insert the cables into the cable
ducts.

uThe power adapter must always be
connected, as the phone will not
operate without a mains connection.
uThe power adapter must always be

nection.

phone cord supplied. Pin connec-
tions on telephone cables can vary
(pin connections, ¢page 52).

been connected or reset.

Initial charging and discharging of the batteries
The correct charge status can only be displayed if the battery is first fully charged
and discharged.
