• Do not remove the unit from the wall nor change
the unit locations. If the unit is reinstalled at
improper location, it may fall or may hit persons
causing injury.

2. FCC REQUIREMENTS

(1) The AI-900 complies with FCC Rules, Part 68. On this equipment is a label which contains, among other

information, the FCC Part 68 registration number.

(2) The ringer equivalence number (REN) is used to determine the quality of devices which may be

connected to the telephone line. Excessive RENs on the telephone line may result in the devices not
ringing in response to an incoming call. In most, but not all areas, the sum of RENs should not exceed five
(5.0). To be certain of the number of devices that may be connected to a line, as determined by the total
RENs, contact the local telephone company.

Note: RENs are associated with loop-start and ground-start ports. It is not used for E&M and digital ports.

The REN assigned to the AI-900 is 0.4. If requested, this information must be given to the
telephone company.

(3) In the event of equipment malfunction, all repairs should be performed by AIPHONE CORPORATION or

an authorized agent. It is the responsibility of users requiring service to report the need for service to
AIPHONE CORPORATION or to one of our authorized agents. Service can be facilitated through our
office at:

AIPHONE CORPORATION
1700-130th Ave., N.E.
Bellevue, Washington 98009
Phone [phone]

The telephone company can ask you to disconnect the equipment from the network until the problem is
corrected or until you are sure that the equipment is not malfunctioning.

4

(4) If the AI-900 disrupts the telephone network, the telephone company can discontinue your service

temporarily. If possible, the telephone company will notify you in advance. If advance notice is not
practical, they will notify you as soon as possible. You are also informed of your right to file a complaint
with the FCC.

(5) The telephone company can make changes in its facilities, equipment, operations, or procedures that can

affect the operation of your equipment. If they do, you should be notified in advance so you have an
opportunity to maintain uninterrupted telephone service.

(6) While the AI-900 is fully compliant with FCC rules and regulations, it is recommended that an alternating

current (ac) surge arrestor of the form and capability suitable for the model purchased be installed in the
ac outlet to which the AIPHONE CORPORATION products are connected. Consult with your distributor as
to the surge protector requirements for your equipment.

(7) The FCC rules require that the following Affidavit be completed by the installer and forwarded to the local

exchange carrier, whenever digital terminal equipment without encoded analog content and billing
protection is used to transmit digital signals containing encoded analog content, which are intended for
eventual conversion into Voiceband analog signals and retransmitted on the network.

(8) The AI-900 has been tested and comply with the limits for a class A digital device, pursuant to Part 15 of

the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction manual,
can cause harmful interference to radio communications. Operation of this equipment in a residential area
is likely to cause harmful interference, in which case the user will be required to correct the interference in
the user's expense.

CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY AIPHONE CORPORATION
COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT.
