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 coordinated by a representative designated by the supplier. Any repairs
or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications

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.
Telecom Requirements
The Messenger Modem does not fully meet telecom's impedance requirements. Performance limitations may occur
when used in conjunction with some parts of the network. Telecom will accept no responsibility should difficulties
arise in such circumstances.
The transmit level from the Messenger Modem is set at a fixed level and because of this, there may be circumstances
where the device does not give its optimum performance. Before reporting such occurrences as faults, check the
line with a standard telephone. Do not report a fault unless the telephone performance is impaired
NOTICE:
The Ringer Equivalence Number (REN) assigned to each 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 the Ringer Equivalence Numbers of all the
devices does not exceed 5. The Messenger Modem REN is 0.3A.
