IMPORTANT INSTRUCTIONS TO USERS
Your IT-A2500 model has been approved by the Federal Communications Commission (FCC) as not
being harmful to the telephone network when connected directly to the telephone lines. In order to
fully comply with the Rules of the FCC, the following instructions should be read carefully and followed
completely
where applicable:
1 The FCC Rules require that all direct connection to the telephone fines must be made through
standard plugs and jacks as called out in the Rules.
No connection can be made to party lines or coin lines.
a. Upon request from your telephone company, you must provide the 14 digit FCC Registration
Number and Ringer Equivalence Number (REN), both of which are on a label located on the
outer surface of your telephone.
b. Inform your local telephone company that the jack (connector) required for your device is USOC
RJTIC.
c. After the telephone company has installed the jack listed above, you can connect your IT-A2500
model by inserting the mating plug of your equipment into the jack.

and still have all of those devices ring when your number is called. In most, but not all areas, the
sum of the RENs of all devices should not exceed five (5.0). To be certain of the number of
devices you may connect to your line, as determined by the REN, you should call your local
telephone company to determine the maximum REN for your calling area.
