TOWER CONSTRUCTION
Compliance with local zoning and tower construction regulations is recommended when VoiceXtender digital
modem radios require a tower. These regulations generally mandate that permits be obtained before any
tower construction begins. Check with local zoning and aviation authorities for more information.
FCC PART 68 INFORMATION
Federal Communications Commission (FCC) Rules on spread spectrum devices, such as the VoiceXtender,
require that you be notified of the following:
This equipment complies with Part 68 of the FCC Rules. The FCC Part 68 label is located on the bottom of
the enclosure. This label contains the FCC Registration Number for this equipment. If requested, this
information must be provided to your telephone company.
The REN is useful to determine the quantity of devices you may connect to your telephone line and still have
all of those devices ring when your telephone number is called. In most, but not all areas, the sum of the
RENs of all devices connected to one line should not exceed five (5.0). To be certain of the number of
devices you may connect to your line, as determined by the REN, you should contact your local telephone
company to determine the maximum REN for your calling area.
Connection to the telephone network should be made by using standard modular telephone jacks, type
RJ11C or RJ11W. The RJ11C or RJ11W plug and/or jacks used must comply with FCC Part 68 rules.
If this telephone equipment causes harm to the telephone network, the telephone company will notify you in
advance that temporary discontinuance of service may be required. But if advance notice isn’t practical, the
telephone company will notify the customer as soon as possible. Also, you will be advised of your right to file
a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in it’s facilities, equipment, operations or procedures that could
affect the proper functioning of your equipment. If they do, you will be notified in advance in order for you to
make necessary modifications to maintain uninterrupted service.
This equipment may not be used on coin service provided by the telephone company. Connection to party
lines is subject to state tariffs.
