Safety precautions
Caution:
Read the safety precautions and the manual before use.
Explain their contents to your children as well as the potential hazards associated with using the
telephone.
u
Only use the mains adapter supplied, as indicated on the underside of the control unit.
This adapter is only intended for use on the Gigaset HC450 and must not be con-
nected to other devices.
Make sure that the mains adapter is accessible at all times.
Do not continue to use broken plugs or plug-in power supply units with broken hous-
ings as they pose a risk of electric shock. Have these parts replaced with genuine spare
parts without delay.
u
The housing of the HC450 control unit and door intercom must not be opened. Unau-
thorised opening of the housing and improper repairs may endanger the user and will
invalidate the warranty.
u
The control unit is designed for indoor operation only. Lay the cables so that nobody
can walk on or trip over them.
u
The control unit includes a radio module in accordance with the DECT standard. The
operation of medical appliances may be affected. Be aware of the technical conditions
in your respective environment, e.g. doctor's surgery.
u
The module must not be installed during a thunderstorm, nor should any cable connec-
tions be plugged in or unplugged, as to do so would expose you to the risk of electric
shock.
u
Do not allow fluids to penetrate the HC450 control unit and door intercom as this could
result in electric shocks or short circuits.
u
Do not use your telephone in environments with a potential explosion hazard, e.g. auto
paint shops.
u
If you give your Gigaset HC450 door intercom to someone else, make sure you also give
them the manual.
u
The entry light may only be installed by a qualified electrician. Please observe the
respective national regulations for the installation of electrical and telecommunica-
tions systems.
u
Only equipment supplying safety extra-low voltage (SELV) and complying with
EN 60950 may be connected to the control unit (actuator output).
