FCC Part 15 Information
This device complies with Part 15 of FCC rules. Operation is subject to the following two
conditions:
1.  This device may not cause harmful interference.
2.  This device must accept any interference received, including interference that may
cause undesired operations.
This equipment has been tested and found to comply with the limits for a CLASS B
digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy, and if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio/television reception, which can
be determined by 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 the receiver.
·  Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
·  Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment. Shielded RS-232 cables are
required to be used to ensure compliance with FCC Part 15, and it is the responsibility of
the user to provide and use shielded RS-232 cables.
FCC Requirements
This equipment complies with Part 68 of the FCC Rules. On the base unit of this
equipment is a label that contains, among other information, the FCC Registration
Number and the Ringer Equivalence Number (REN) for this equipment.
IF REQUESTED, THIS INFORMATION MUST BE GIVEN TO THE TELEPHONE

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 total RENs, you should contact your local
telephone company to determine the maximum REN for your calling area.
If your equipment causes harm to the telephone network, the telephone company may
discontinue your service temporarily. If possible, they will notify you in advance. But if
