Brother MFC-J3720 Product Safety Manual page 16

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.
27 This equipment is not capable, under all operating conditions, of correct operation at the higher
speeds for which it is designed. Telecom will accept no responsibility should difficulties arise
in such circumstances. This condition typically applies to 56 kbit/s modems and facsimile
machines operating at >14.4 kbit/s.
28 When using the Caller Line Identification incorporated in this device, verify the integrity of the
recorded digits prior to dialling.
29 Some parameters required for compliance with Telecom's Telepermit requirements are
dependent on the equipment (PC) associated with this device. The associated equipment shall
be set to operate within the following limits for compliance with Telecom's Specifications:
 There shall be no more than 10 call attempts to the same number within any 30 minute
period for any single manual call initiation.
 The equipment shall go on-hook for a period of not less than 30 seconds between the end
of one attempt and the beginning of the next call attempt.
 Automatic calls to different numbers are spaced such that there is not less than 5 seconds
between the end of one call attempt and the beginning of another.
Equipment shall be set to ensure that calls are answered within 3 and 30 seconds of the

receipt of ringing.
30 In the event of any problem with this device, it is to be disconnected, and a CPE item connected
to one of its terminal ports may be connected directly in its place.
The user should then arrange for the product to be repaired. Should the matter be reported to
Telecom as a wiring fault and the fault is proven to be due to this product, a call out charge will
be incurred by the customer.
31 The Caller ID telephone numbers that are displayed and stored in this equipment include the
caller's area code but not the toll access "0" prefix. When calling back it is necessary to add a
"0" to the telephone number, or if the telephone number is a local number, omit the area code
digit. If the toll services of a service provider other than Telecom are being used then a toll
charge may be incurred if the "0" prefix toll access code and area code are used.
