FCC INFORMATION  
SAFETY INSTRUCTIONS  
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.  
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:  
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:  
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.  
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.  
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.  
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.

2. Do not dispose of the batteries in a fire. The cells may explode. Check with local codes for possible special disposal  
instructions.  
3. Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may  
be toxic if swallowed.  
4. Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets and  
keys. The battery or conductor may overheat and cause burns.  
5. Do not attempt to recharge the batteries that are with or identified for use with this product. The batteries may leak corrosive  
electrolyte or explode.  
6. Do not attempt to rejuvenate the batteries provided with or identified for use with this product by heating them. Sudden  
release of the battery electrolyte may occur causing burns or irritation to eyes or skin.  
7. When replacing batteries, all batteries should be replaced at the same time. Mixing fresh and discharged batteries could  
increase internal cell pressure and rupture the discharged batteries.  
8. When inserting the batteries into this product, the proper polarity or direction must be observed. Reverse insertion of  
batteries can cause charging, which may result in leakage or explosion.  
9. Remove the batteries from this product if the product will not be used for a long period of time (several months or more)  
since during this time the batteries could leak, damaging the product.  
10. Discard “dead” batteries as soon as possible since they are more likely to leak in a product.  
11. Do not store this product, or the batteries provided with or identified for use with this product, in high temperature areas.

CARE AND MAINTENANCE  
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:  
Use the [L] and [M] buttons to adjust the volume:  
If the speakerphone is turned on, press [L] and [M] to adjust the  
speakerphone volume up and down.  
If the handset is picked up, press [L] and [M] to adjust the handset volume

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.

starting on page 15), the phone will receive VMI (or visual message indication)  
for one or none of the four lines.

casing. Use only mild detergents on a soft, damp cloth to clean the B450D  
telephone.

requirements. However, an incident such as a lightning strike at or near the

storms, it is suggested that the telephone be disconnected during these  
storms or that additional surge suppression equipment be added to the  
installation.  
Note: This function requires voice mail subscription  
from the local telephone company. Furthermore, the local phone  
company must provide a type of voice mail signaling called FSK”  
(Frequency Shift Key). Not all telephone companies have the visual  
message waiting feature (or the deactivate signal) available. Please  
contact your local telephone company to check if this is available in  
your area.  
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.  
If it is necessary to manually cancel VMI indication:  
1. While MESSAGE WAITINGis on the display, press [ DEL].  
2. The B450D will display CANCEL MSG WAIT?”
