With each device shipped,there is a label which contains, among other information, the FCC Registration Number and
Ringer Equivalence Number (REN) for this product. You must, upon request, give this information to your telephone
company.
Mounting this device in the final assembly must be made in such a manner as to preserve the high voltage protection
between the TIP/RING connection and the rest of the system. Typically, this may be accomplished by maintaining a
minimum spacing .100 mils between the TIP/RING trace to the RJ-11C Jack and low voltage portion of the system. No
additional circuitry may be attached between TIP/RING and the telephone line connection unless specifically allowed in
the rules.
The REN is useful to determine the quantity of devices you may connect to the telephone line and still have all of these
devices ring when the 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 the line, as determined by
the REN, you should contact the local telephone company to determine the maximum REN for your calling area.
If your system causes harm to the telephone network, the telephone company may discontinue service temporarily. If
possible, they will notify you in advance. If advance notification is not practical, you will be notified as soon as possible.
Your telephone company may make changes in its facilities, equipment, operations or procedures that could affect
proper functioning of your equipment. If they do, you will be notified in advance to give you an opportunity to maintain
uninterrupted service.
