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.
