Section 2 — FCC Information
2.1 Part 68 Compliance
The DAI-2 complies with Part 68 of the FCC rules. On the rear panel of the DAI-2 is a label that contains, among other
information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this
information must be provided to the telephone company.
The REN is used to determine the quantity of devices that may be connected to the telephone line. Excessive RENs
on the telephone line may result in devices not ringing in response to an incoming call. In most areas, the sum of the
RENs should not exceed 5.0. Contact the local telephone company to determine the maximum REN for the calling
area.
The DAI-2 is designed for use with standard modular (RJ11C) telephone jacks.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect
the operation of the DAI-2. If this happens, the telephone company will provide advance notice in order for you to
make the necessary modifications to maintain uninterrupted service.
If the DAI-2 causes harm to the telephone network, the telephone company will notify you in advance of service
disconnection. 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.
Please contact Sine Systems, Inc., for repair and/or warranty information if you suspect that the DAI-2 has
malfunctioned. If a defective device is causing harm to the telephone network, the telephone company may request
you remove that device from the network until the problem is resolved.
The DAI-2 cannot be used on public coin service lines provided by the telephone company. Connection to Party Line
Service is subject to state tariffs. Contact your state public utility commission, public service commission, or
corporation commission for information.
The DAI-2 is registered with the Federal Communications Commission and is certified to meet specific safety
requirements. It is extremely important that the DAI-2 not be modified in any way. Modification of this equipment will
void the FCC certification, void the warranty, and perhaps pose a hazard to the user of this equipment or to
maintenance personnel of your local telephone company.
Service should be performed only by qualified technical personnel who are familiar with the implications of FCC Part
68 registration. Extreme caution should be used if the DAI-2 case is opened while still connected to the telephone
line. High voltages may be present on telephone lines.
