4. This device is equipped with pulse dialing, while the Telecom standard is DTMF
tone dialing. There is no guarantee that Telecom lines will always continue to
support pulse dialing.
Use of pulse dialing, when this equipment is connected to the same line as other
equipment, may give rise to ‘bell tinkle’ or noise and may also cause a false an-
swer condition. Should such problems occur, the user should not contact the
Telecom Faults Service.
The preferred method of dialing is to use DTMF tones, as this is faster than
pulse (decadic) dialing and is readily available on almost all New Zealand tele-
phone exchanges.
5. Warning Notice: No ‘111’ or other calls can be made from this device during a
mains power failure.
6. This equipment may not provide for the effective hand-over of a call to another
device connected to the same line.
7. Some parameters required for compliance with Telecom’s Telepermit require-
ments are dependent on the equipment (PC) associated with this device. The as-
sociated equipment shall be set to operate within the following limits for

•The equipment shall go on-hook for a period of not less than 30 seconds be-
tween the end of one attempt and the beginning of the next attempt.
For automatic calls to different numbers:
•The equipment shall be set to ensure that automatic calls to different num-
bers are spaced such that there is no less than 5 seconds between the end of
one call attempt and the beginning of another.
For automatically answered incoming calls:
•The equipment shall be set to ensure that calls are answered between 3 and
30 seconds of receipt of ringing.
8. For correct operation, total of the RNs of all devices connected to a single line at
any time should not exceed 5.
