Interference Information: Part 15 of FCC Rules

This equipment generates, uses, and can radiate low-level radio frequency energy. It
has been tested and found to comply with the limits for a Class B digital device in
accordance with the specifications in Part 15J of the FCC Rules, which are designed to
provide reasonable protection against such interference in a residential installation. If
this equipment does cause interference to radio or television reception—which can be
determined by unplugging it from the telephone line—the user is encouraged to try to
correct the interference by one or more of the following measures:
Where it can be done safely, reorient the radio or TV receiving antenna.To the extent
possible, relocate the television, radio, or other receiver with respect to the telephone
equipment.

If your telephone product runs on AC power, plug your product into an AC outlet that’s
not on the same circuit as the one used by the radio or television. If necessary, the user
should consult the dealer or an experienced radio/television technician for additional
suggestions.

SAFETY INSTRUCTIONS

4

Your B450D telephone is registered with the Federal Communications Commission and
it complies with part 15J and Part 68 of the FCC Rules and Regulations. Modifying or
tampering with the telephone’s internal components can cause a malfunction and might
invalidate the telephone’s warranty and void your FCC authorization to operate it.

The FCC requires us to provide you with the following information:

1. The FCC requires that you connect to a nationwide telephone network through a
modular telephone outlet that is Part 68 compliant. The B450D telephone cannot be
used with coin service provided by the telephone company. Connection to party
lines is subject to state tariffs. Check with your local telephone company.

2. FCC rules require that upon request you provide the following information to the
phone company:
A. The line (telephone number) to which you will connect the telephone equipment,

and

B. The FCC Registration Number and Ringer Equivalence Number (REN). These

numbers can be found on a label on the back or bottom of you telephone
equipment.
The REN is useful to determine the number of devices you may connect to your
telephone line and still have all devices ring when your telephone number is
called. In most cases (but not all areas), the sum of REN’s of all the devices
connected to one line should not exceed (5) five. The B450D telephone utilizes
high sensitivity ringer circuits, which will function reliably with up to twelve
telephones installed.

3. If it is determined that your telephone equipment is malfunctioning, the FCC requires
that it not be used and be unplugged from the modular outlet until the problem has
been corrected. Repairs to this telephone equipment can be made only by the
manufacturer or its authorized agents, or by others who may be authorized by the
FCC. Unauthorized repairs void registration and warranty.

4. The telephone company may discontinue service if the telephone is determined to
cause harm to the telephone network. In this case, the telephone company will:
A. If possible, notify the customer in advance that the service is being discontinued.
B. Provide the customer with the opportunity to correct the situation.
C. Inform the customer of their right to file a complaint with the FCC.
Your local telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect the proper functioning of your equipment.
If they do, you will be notified in advance to give you an opportunity to maintain
uninterrupted telephone service.

5. The B450D telephone is Hearing Aid Compatible.

6. When programming/testing emergency numbers and/or making test calls to
emergency numbers:
A. Remain on the line and briefly explain to the dispatcher the reason for the call

before hanging up.

B. Perform such activities in the off-peak hours, such as early morning or late

evening.

Your B450D telephone has been designed to give years of trouble-free service.
It is a sensitive electro-mechanical instrument. To assure its longevity, please
read the following maintenance instructions:

1. Keep the B450D away from heat as high temperatures can shorten the life
of the electrical components and distort or melt its plastic parts.

2. The B450D should be kept free of dust and moisture. If it gets wet, wipe it
dry immediately. Liquids can contain minerals that can corrode electronic
circuits.

3. Handle your B450D gently and carefully. Dropping it can cause serious
damage to circuitry or the plastic case, which may result in malfunctions.

4. Do not use any type of chemical or any abrasive powder to clean the outer
casing. Use only mild detergents on a soft, damp cloth to clean the B450D
telephone.

5. The B450D has built-in surge protection circuits that meet or exceed FCC
requirements. However, an incident such as a lightning strike at or near the
telephone lines, could cause serious damage.

6. If the B450D is installed in an area with frequent or severe electrical
storms, it is suggested that the telephone be disconnected during these
storms or that additional surge suppression equipment be added to the
installation.

7. In the case of trouble with the telephone, do not attempt to repair the
telephone yourself. It is the responsibility of users requiring service to
report the need for service to our Service Department. They will make the
necessary arrangements for repair or replacement.
