2.4 Start up
The SmartLine D711/721 is connected to an ISDN S
0
DSS1 point-to-multi-
point connection or to a corresponding telecommunications system.
Note: Please note that the S
0
bus must be terminated on both ends with
2 x 100 Ohm.
Location
Avoid placing the telephone in the direct proximity of other electronic devi-
ces such as HiFi units, office machines or microwave units, thus ruling out
mutual influences. Do not place the telephone close to heat sources such
as radiators.
Today's furniture is coated with a vastly diverse amount of lacquers and
plastics and is treated with diverse care agents. Therefore, it cannot be
ruled out that some of these substances may contain components that will
be aggressive to the telephone's plastic feet and will soften them with the
result that they leave behind unpleasant traces.
Connecting
Connect the handset to the housing with the coiled handset cord. Insert the
end with the shorter uncoiled portion in the socket on the handset. Then
connect the telephone to the telephone network by means of the telephone
connecting lead. The telephone starts with a display test, during which time
all pixels and pictograms are displayed for about 10 seconds. You can now
make telephone calls.
