FCC Instructions
This product complies with part 68 of the FCC Rules and Regulations. 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, provide this information to
your telephone company.
The mounting of 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 Traces 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 a 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 you 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 telephone service.
If you experience trouble with this device, please contact XECOM at (408) 945-6640 for
information on obtaining service or repairs. The telephone company may ask you to disconnect
this device from the network until the problem has been corrected or until you are sure that the
device is not malfunctioning.
The device may not be used on coin service lines provided by the telephone company (this does
not apply to private coin telephone applications which use standard telephone lines). Connection
to party lines is subject to state tariffs.
