SDM-9XXX Series Hardware Installation Guide
B-14 Memotec Inc.
Operation in a residential area may cause unacceptable interference to radio and TV
reception requiring the owner or operator to take whatever steps necessary to correct the
interference.
The SDM-9220 and the SDM-9230 meet the applicable Industry Canada technical
specifications.
The Industry Canada label identifies certified equipment. The certification means that the
equipment meets certain telecommunications network protective, operations, and safety
requirements as prescribed in the appropriate Terminal Equipment Technical
Requirements document(s). The Industry Canada 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. 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 a Memotec Inc. authorized maintenance
facility. 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.
Users should not attempt to make such connections themselves, but should contact
the appropriate electric inspection authority, or electrician, as appropriate.
The Ringer Equivalence Number (REN)
The Ringer Equivalence Number assigned to each terminal device provides an indication
of the maximum number of terminals allowed to be connected to a telephone interface.
The termination on an interface may consist of any combination of devices subject only to
the requirement that the sum of Ringer Equivalence Numbers of all the devices does not
exceed 5.
