the bottom of this equipment is a label that contains, among
other information, the FCC Registration Number and Ringer
Equivalence Number (REN) for this equipment. If requested,
this information must be given to the telephone company.

The REN is used to determine the maximum number of devices
connected to your telephone line that will ring in response to an
incoming call. In most, but not all, areas, the total REN of
devices connected to a line should not exceed five (5.0). To find
out the total permitted in your area, contact your local telephone
company.

If your telephone equipment causes harm to the telephone network,
the telephone company may discontinue your service temporarily.
If possible, the company will notify you in advance. But if advance
notice isn’t practical, you will be notified as soon as possible. You
will also be informed of your right to file a complaint with the FCC.
If your equipment is the cause of the problem, you will be given the
opportunity to correct the problem.

Your telephone company can make changes in its facilities,
equipment, operations, or procedures that could affect the
operation of your equipment. If so, you will be notified in
advance so you can make the changes needed to maintain
uninterrupted service.

vii

If you experience trouble with this telephone equipment,
please contact Simple Technology at 1-800-367-7330 for
information on obtaining service or repairs. The telephone
company may ask that you disconnect this equipment from
the network until the problem has been corrected or until you
are sure that the equipment is not malfunctioning.

This equipment contains no user serviceable parts.
This equipment may not be used on public coin service or party

lines.

FCC Part 15 Requirements

This equipment has been tested and found to comply with the limits
for a class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable pr otection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However , there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measur es:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and
receiver.

• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician
for help.

The user is cautioned that changes and modifications made to
this equipment without the approval of the manufacturer could
void the user’s authority to operate this equipment. There are no
user-serviceable parts in this equipment. The unit must be
returned to the manufacturer for any repairs.

DOC Certification Label

The Canadian Department of Communications (DOC) label
identifies certified equipment. This certification means that the
equipment meets certain telecommunications network protective,
operational, and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it
is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be
installed using an acceptable method of connection. In some
cases, the company’s inside wiring associated with a single
line individual service may be extended by means of a
certified connector assembly (telephone extension cord). The
customer should be aware that compliance with the above
conditions may not prevent degradation of service in some
situations.

Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical
ground connections of the power utility, telephone lines, and
internal metallic water pipe system, if present, are connected
together. This precaution may be particularly important in rural
areas.

CAUTION: Do not attempt to make electrical ground

connections yourself; contact the
appropriate electric inspection authority
or an electrician.

ix

The LOAD NUMBER (LN) assigned to each terminal device
denotes the percentage of the total load to be connected to a
telephone loop which is used by the device, to prevent
overloading. The termination on a loop may consist of any
combination of devices subject only to the requirement that
the sum of the LOAD NUMBERS of all the devices does not
exceed 100.

Etiquette D’Homologation du Ministere
des Communications du Canada

AVIS : L’etiquette du ministere des Communications du Canada
identifie le materiel homologue. Cette etiquette certifie que le
materiel est conforme a certaines normes de protection,
d’exploitation et de securite des reseaux de telecommunications.
Le ministere n’assure toutefois pas que le materiel fonctionnera a
la satisfaction de l’utilisateur.

x

Avant d’installer ce materiel, l’utilisateur doit s’assurer qu’il est
permis de le raccorder aux installations de l’entreprise locale de
telecommunications. Le materiel doit egalement etre installe en
suivant une methode acceptee de raccordement. L’abonne ne
doit pas oublier qu’il est possible que la conformite aux condi­tions enoncees ci-dessus n’empechent pas la degradation du
service dans certaines situations.

Les reparations de materiel homologue doivent etre effectuees
par un centre d’entretien canadien autorise designe par le
fournisseur. La compagnie de telecommunications peut de­mander a l’utilisateur de debrancher un appareil a la suite de
reparations ou de modifications effectuees par l’utilisateur ou a
cause d’un mauvais fonctionnement.

Pour sa propre protection, l’utilisateur doit s’assurer que tous les
fils de mise a la terre de la source d’energie electrique, des lignes
telephoniques et des canalisations d’eau metalliques, s’il y en a,
sont raccordes ensemble. Cette precaution est particulierement
importante dans les regions rurales.

AVERTISSEMENT : l’utilisateur ne doit pas tenter de faire ces
raccordements lui-meme, il doit avoir recours a un service
d’inspection des installations electriques ou a un electricien,
selon le cas.

AVIS : L’INDICE DE CHARGE (IC) assigne a chaque dispositif
terminal indique, pour eviter toute surcharge, le pourcentage de
la charge totale qui peut etre raccorde a un circuit telephonique
boucle utilise par ce dispositif.

L’extremite du circuit boucle peut consister en n’importe quelle
combinaison de dispositifs pourvu que la somme des INDICES
