Commissioning the System
Important:
Do not expose the devices to constant sunlight or other strong sources of heat.
Do not expose the devices to strong electro-magnetic fields (e. g. electric motors,
TVs, video, radio and other household appliances). The voice quality might be
affected in that case.
Installation Location
When installing the COMfortel DECT system, you need to make sure to select the best possible loca-
tion with regard to the propagation of radio waves. Rooms in the basement are generally unsuitable
for an installation. The transmitting and receiving devices of the COMfortel DECT system should be
installed at a height of above 2 m so that the radio signal will not be affected by people walking by.
However, they should not be mounted too high, either, especially if there are steel beams in the cei-
ling. If outdoor areas are to be covered as well, seasonal changes need to be taken into account (e. g.
leaves on the trees).
To install the COMfortel DECT 900 base, you only need a connection to an internal S
0
port on the
PBX. You do not need to ensure a 230-V power supply.
When installing a repeater (COMfortel DECT Repeater.2), you need to have a freely accessible 230-
V Schuko socket in the immediate vicinity of the mounting location. A repeater always needs to be
located within the reception range of the base station or another repeater. You cannot cascade more
than two repeaters (see
Abb. 9 on page 65).
To bridge larger ranges, we recommend the use of directional antennas (COMfortel DECT Antenna).
They allow distances of up to 1000 m to be bridged (outside enclosed rooms and with intervisibility).
The directional antenna is connected to a repeater and directed to the nearest repeater or directly to
the base station (see
Abb. 13 on page 68).
The COMfortel DECT system devices are meant to be mounted on a wall. You can find the required
drilling templates on
Page 88 (COMfortel DECT 900 Base), on Page 90 (COMfortel DECT Repea-
ter.2) and on the back of the outer package (COMfortel DECT Antenna).
