23
This unit will only work in conjunction with a tone signalling
(DTMF) telephone, but some telephones are not compatible.
Since noise or speech from the telephone can upset dialling
from this unit, errors may result if the devices are used together
in other than quiet conditions.
24
Where it is necessary to dial prefix digits, such as a Caller
Display override code (“0196” or “0197”), this unit will have to be
used in conjunction with an associated tone signalling (DTMF)
telephone.
25
Note that some telephones are not compatible with this unit and
dialling errors may result if the two devices are used together in
other than quiet conditions. The Telecom Faults Service is not
to be called should such problems arise. In such cases, it is
recommended that the prefix and wanted number are dialled
manually.
26
This equipment may not provide for the effective hand-over of a
call to another device connected to the same line.
