Setting up the base station or charging unit
➭
Do not expose the base station or charging unit to direct sunlight.
➭
Protect the base station or charging unit against moisture. Do not position the base
station or charging unit in rooms exposed to condensation, corrosive steam or excessive
dust. Condensation can be present in basements, garages, conservatories or sheds.
➭
The ambient temperature must be between 5 °C and 40 °C.
Position the base station and charging unit in a clean, dry and well-aired location. Choose
a place which is stable, level, and not subject to vibrations. To avoid mutual interference,
do not position the base station or charging unit in the immediate vicinity of electronic
equipment such as hi-fi systems, office equipment or microwave ovens. Avoid positioning
the telephone near heat sources such as heating elements or near obstacles such as
metal doors, thick walls, niches and cupboards.
There is no mains switch on the base station or charging unit. For this reason the socket
to which it is connected must be easy to access.
Listening protection
When you are on the telephone, the base station and handset are connected to each
other over a radio link. The base station handles switching between the telephone net-
work and the handset. To ensure that no-one can eavesdrop or telephone at your cost,
the base station and handset exchange codes. If the codes do not match, the connection
with third-party handsets cannot be set up.
