Canadian Limitations Notice
Notice:
The ringer equivalence number (REN) assigned to each terminal device provides an
indication of the maximum number of terminals allowed to be connected to a telephone
interface. The termination of a interface may consist of any combination of devices subject only
to the requirement that the sum of the ringer equivalence numbers of all the devices does not
exceed 5.
Notice:
The Industry Canada label identifies certificated equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and
safety requirements. The Industry Canada does not guarantee the equipment will operate to
the users 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. 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:
Users should not attempt to make such connections themselves, but should contact
the appropriate electric inspection authority, or electrician, as appropriate.
Compliance with BABT Requirements
Approved for connection to telecommunications system specified in the instructions for use
subject to the conditions set out in them.
Warning:
Interconnection directly, or by way of other apparatus, of ports marked "SAFETY
WARNING see instructions for use" with ports marked or not so marked may produce hazardous
conditions on the network. Advice should be obtained from a competent engineer before such a
connection is made.
It is a condition of approval that the power required by the host and the total of all adapter cards
installed within the host environment, together with any auxiliary apparatus, does not exceed the
power specification as stated in the Technical Reference Material of the host apparatus.
The power requirements for the MULTIMODEMISI are:
Modem operating voltages: +12V D.C., -12V D. C., +5V D.C.
Modem Power Consumption: 8 Watts
In order to maintain the independent approval of this card, it is essential that when other option
cards are introduced which use or generate a hazardous voltage, the minimum creepages and
clearances specified in the following table are maintained. A hazardous voltage is one which
exceeds 42.4V peak a.c or 50V d.c. If you have any doubt, seek advice from a competent
engineer before installing other adapters into the host equipment.
The equipment must be installed such that with the exception of connection to the host,
clearance and creepage distances shown in the following table are maintained between the card
and any other assemblies which use or generate a voltage shown in that table. The larger the
distance shown in brackets applies where the local environment within the host is subject to
