turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.

could void the user’s authority to operate the equipment.
FCC Part 68 Telecom
1. This equipment complies with Part 68 of the 47 CFR rules and the requirements adopted by the ACTA.
Located on this equipment is a label that contains, among other information, the registration number and
Ringer Equivalence Number (REN) for this equipment or a product identifier in the format:
For current products: US:AAAEQ##Txxxx.
For legacy products: AU7USA-xxxxx-xx-x.
If requested, this number must be provided to the telephone company.
2. A plug and jack used to connect this equipment to the premises wiring and telephone network must comply
with the applicable 47 CFR Part 68 rules and requirements adopted by the ACTA. It’s designed to be
connected to a compatible modular jack that is also compliant.
3. The Ringer Equivalence Number (REN) is used to determine the number of devices that may be connected to
a telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an
incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the
number of devices that may be connected to a line, as determined by the total RENs, contact the local
telephone company. For products approved after July 23, 2001, the REN for this product is part of the
product identifier that has the format US:AAAEQ##Txxxx. The digits represented by ## are the REN without
a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately shown on the label.
4. If this 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.
