Connections
Warning!: please, before you start any connections
refer to section “Safe and Efficient Use” on page 49
in this guide and contact your network operator if
you have any questions.
Warning!: to get a good FCT protection against
electrical discharges and the best audio quality, a
good grounding of the power supply is strongly
recommended.
Installing the FCT as a telephone line
The FCT is designed to provide a telephone line
(RJ11 connector) to which up to 3 Fixed Line devices
can be connected in parallel. The FCT provides a
single telephone line, which means that only one
communication can take place simultaneously, in the
same way as the ordinary fixed line (you cannot, for
example, receive or originate a telephone call while
sending or receiving a fax).
Warning!: in order to avoid GSM interferences
(noise), place the FCT at least 3 meters (horizontal)
away from electronic devices, including the
telephone equipment connected to the FCT, or other
household electronic devices such as televisions or
radio receivers. The difference in height should be
at least 2 meters (vertical). This is not necessary if
you use telephone devices that fulfil the Immunity
Characteristics settled by the IEC CISPR-24
standard. In this case, a minimum security distance
of 20 cm is recommended.
