equipment. Users should ensure for their own protection that the earth ground
connections of the power utility, telephone lines and internal metallic water pipe

Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or
electrician, as appropriate.
Note:
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

Type of Service
The TX3 is designed to be used on standard device telephone lines. It connects to

Telephone Company Procedures
The goal of the telephone company is to provide you with the best service it can.
In order to do this, it may occasionally be necessary for them to make changes in
their equipment, operations or procedures. If these changes might affect your
service or the operation of your equipment, the telephone company will give you
notice, in writing, to allow you to make any changes necessary to maintain
uninterrupted service.
In certain circumstances, it may be necessary for the telephone company to
request information from you concerning the equipment which you have
connected to your telephone line. Upon request of the telephone company,
provide the FCC registration number and the ringer equivalence number (REN);
both of these items are listed on the equipment label. The sum of all of the RENs
on your telephone lines should be less than five in order to assure proper service
from the telephone company. In some cases, a sum of five may not be useable on
a given line.
