Regulatory
Information
SECTION 1ELECTROMAGNETIC INTERFERENCE (EMI)
WARNING
This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
SECTION 2INCIDENCE OF HARM
If the System is malfunctioning, it may also be causing harm to the telephone network.
The Telephone system should be disconnected until the source of the problem can be
determined and until repair has been made. If this is not done, the Network Provider
may temporarily disconnect the service.
SECTION 3HEARING AID COMPATIBILITY
The NEC Multiline Terminals that are provided for this system are hearing aid
compatible. The manufacturer of Single Line Telephones for use with the system must
provide notice of hearing aid compatibility to comply with ACA Technical Standards.
SECTION 4SERVICE REQUIREMENTS

Chapter 1

Chapter 1 - 2 Regulatory Information
NEC Business Solutions Ltd XEN Topaz
Doc. No. 8802 - Release 2.0 April 2005
SECTION 6 CONNECTION REQUIREMENTS FOR EARTHING THE TOPAZ KSU
Because this Topaz KSU has been ACA approved as an Earthed-SELV Customer
Switching System for connection to a telecommunications network, the KSU Earth
terminal E(on the 308M System Mainboard) MUST be permanently connected to
Earth by connecting a minimum of 2.5mm2 green/yellow conductor cable.
This cable MUST be connected between a Multiple Earth Neutral (MEN) Bonding Bar
at the nearest convenient mains Switch Board to the KSU. This cable must serve no
other purpose than installing the KSU.
CAUTION: If this cable is not installed or requires disconnection, then the
telecommunication network connection(s), namely CO and/or ISDN, must be
disconnected first from the KSU.
Liability for this installation rests solely with the licensed installer/dealer. It is
recommended that the installer provide their label and it is to be placed in the Main
Switch Board, certifying that the installation complies with the safety earthing
installation manual instructions for the Topaz KSU Section 3.1.
(Technical References: AS/NZS 60950:2000, ACIF S009:2001. See Protective
Earthing Conductor requirements.)
SECTION 7 VOICE ANNOUNCEMENT/MONITORING
CAUTION
The use of monitoring, recording or listening devices to eavesdrop, monitor, retrieve or
record telephone conversations or other sound activities, whether or not
contemporaneous with its transmission may be illegal in certain circumstances under
federal or state laws. Legal advise should be sought prior to implementing any practice
that monitors or records any telephone conversation. The telecommunications
(Interception) Act 1979 (Cth), The telecommunications Act 1997, The Privacy Act 1988
and State and Territory Listening Devices Legislation are all relevant. Some federal and
state laws require some form of notification to all parties to the telephone conversation,
such as using a beep tone or other notification methods, or require the consent of all
parties to the telephone conversation, prior to monitoring or recording a telephone
conversation. Some of these laws incorporate strict penalties. Section 6 of the Industry
Guidelines recommend pre-recorded messages or verbal notification to alert callers
that the calls may be monitored:
For example: “Your call may be listened to and recorded for quality and coaching
purposes. Please tell the consultant if you don’t want this to happen.”
Section 6 of the Industry Guidelines also make recommendations in relation to
notifications in writing.

About This Manual
SECTION 1FEATURES
Before Reading This Section
This section provides detailed information on the system's features. If you don't know
what the various features are, review the Table of Contents for this section and the
manual's Index. After reviewing, turn back to this section for the specifics.
Using This Section
The features in this section are in alphabetical order, like a dictionary. This section
subdivides each feature definition into headings as follows:
The Compatibility Chart at the top of each feature shows you if the feature is
available for each system and what system software is required.
Description tells what the feature is and describes its benefits. Along with the
Description are the Conditions and Default Setting. Conditions provides the feature's
operational limits (if any). Default Setting outlines how the feature works with the
default programming. When initially installed, the system uses the default setting. For
specific default settings on each program, refer to the chart at the end of this book.
Programming explains the system programming that lets you customize the feature.
Some features require programming; other's don't. If you decide to customize a
feature, use Section 2 to enter the change into the system.
Related Features presents the feature interaction.
Operation consists of instructions on how to use each feature.
Read These Notes
Simplifying System Phone Operation with One-Touch Keys
A system phone user can access many features through Service Codes (e.g., Service
Code 841 answers a Message Waiting indication from a co-worker). To streamline the
operation of their phone, a system phone user can store these codes under One-Touch
Keys. This provides one-button operation for almost any feature. To find out more, turn
to the One-Touch Calling and One-Touch Serial Operation features.
Programmable Keys
When reading an instruction using programmable keys, you will see a notation similar
to (PGM 15-07 or SC nnn). This means that the key requires function code nnn, and
you can program this code through Program 15-07 or by dialling Service Code 851 or
852. Refer to the Programmable Function Keys feature for more information.
