If this product contains an internal modem it is
compliant with Part 68 of the Federal Communications
Commission Rules and Regulations and there will be a
label on the product showing the FCC ID Number and
the REN, Ringer Equivalence Number. The REN is used
to determine the quantity of devices which maybe
connected to the telephone line. Excessive RENs on the
telephone line may result in the device not ringing in
response to an incoming call. In most but not all areas,
the sum of the RENs should not exceed 5.0. To be
certain of the number of devices that may be connected
to the line, as determined by the total number of RENs,
contact the telephone company to determine the
maximum REN for the calling area.
If the modem causes harm to the telephone network,
the telephone company will notify you in advance;
however, if advance notice is not practical, you will be
notified 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 its
acilities, equipment, operations or procedures that
could affect the operation of the modem. If this happens
the telephone company will provide advance notice so
you may make any necessary modifications to maintain
uninterrupted service.
