This equipment complies with Part 68 of the 
FCC rules and the requirements adopted by 
the ACTA. On the bottom of this equipment 
is a label that contains, among other 
information, a product identifier in the 
format US:ACJ----------.
If requested, this number must be provided 
to the telephone company.
L Registration No.............(found on the bottom of the unit)
L Ringer Equivalence No. (REN).......0.1B
A plug and jack used to connect this 
equipment to the premises wiring and 
telephone network must comply with the 
applicable FCC Part 68 rules and 
requirements adopted by the ACTA. A 
compliant telephone cord and modular plug 
is provided with the product. It is designed 
to be connected to a compatible modular 
jack that is also compliant.
The REN is used to determine the number 
of devices that may be connected to a 
telephone line. Excessive RENs on a 
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. For products approved after July 
23, 2001, the REN for the product is part of 
the product identifier that has the format 
US:AAAEQ##TXXXX. The digits 
represented by ## are the REN without a 
decimal point (e.g., 03 is a REN of 0.3).
If this equipment causes harm to the 
telephone network, the telephone company 
will notify you in advance that temporary 
discontinuance of service may be required. 
But if advance notice isnt practical, the 
telephone company will notify the customer 
as soon as possible. Also, you will be 
advised of your right to file a complaint with 
the FCC if you believe it is necessary. The telephone company may make changes 
in its facilities, equipment, operations or 
procedures that could affect the operation of 
the equipment. If this happens the 
telephone company will provide advance 
notice in order for you to make necessary 
modifications to maintain uninterrupted 
service.
If trouble is experienced with this 
equipment, for repair or warranty 
information, please contact a Factory 
Service Center or other Authorized Servicer. 
If the equipment is causing harm to the 
telephone network, the telephone company 
may request that you disconnect the 
equipment until the problem is resolved.
Connection to party line service is subject to 
state tariffs. Contact the state public utility 
commission, public service commission or 
corporation commission for information.
If your home has specially wired alarm 
equipment connected to the telephone line, 
ensure the installation of this equipment 
does not disable your alarm equipment. If 
you have questions about what will disable 
alarm equipment, consult your telephone 
company or a qualified installer.
This equipment is hearing aid compatible as 
defined by the FCC in 47 CFR Section 
68.316.
When you hold the phone to your ear, noise 
might be heard in your Hearing Aid. Some 
Hearing Aids are not adequately shielded 
from external RF (radio frequency) energy. If 
noise occurs, use an optional headset 
accessory or the speakerphone option (if 
applicable) when using this phone. Consult 
with your audiologist or Hearing Aid 
manufacturer about the availability of 
Hearing Aids which provide adequate 
shielding to RF energy commonly emitted 
by digital devices.

WHEN PROGRAMMING EMERGENCY 
NUMBERS AND(OR)  MAKING TEST 
CALLS TO EMERGENCY NUMBERS:
1) Remain on the line and briefly explain to the dispatcher the reason for the call.
2) Perform such activities in the off-peak  hours, such as early morning or late 
evenings.
This device complies with Part 15 of the 
FCC Rules. Operation is subject to the 
following two conditions:
(1) This device may not cause harmful 
interference, and (2) this device must 
accept any interference received, including 
interference that may cause undesired 
operation.
Privacy of communications may not be 
ensured when using this phone.
CAUTION:Any changes or modifications not expressly 
approved by the party responsible for 
compliance could void the user’s authority 
to operate this device.
NOTE:This equipment has been tested and found 
to comply with the limits for a Class B digital 
device, pursuant to Part 15 of the FCC 
Rules. These limits are designed to provide 
reasonable protection against harmful 
interference in a residential installation. This 
equipment generates, uses, and can radiate 
radio frequency energy and, if not installed 
and used in accordance with the 
instructions, may cause harmful 
interference to radio communications. 
However, there is no guarantee that 
interference will not occur in a particular 
installation. If this equipment does cause 
harmful interference to radio or television 
reception, which can be determined by 
turning the equipment off and on, the user is 
encouraged to try to correct the interference 
by one or more of the following measures:
– Reorient or relocate the receiving  antenna.
– Increase the separation between the  equipment and receiver.
– Connect the equipment into an outlet on a  circuit different from that to which the 
receiver is connected. – Consult the dealer or an experienced 
radio/TV technician for help.
Some cordless telephones operate at 
frequencies that may cause interference to 
nearby TVs and VCRs. To minimize or 
prevent such interference, the base of the 
cordless telephone should not be placed 
near or on top of a TV or VCR. If  
interference is experienced, move the 
cordless telephone further away from the TV 
or VCR. This will often reduce, or eliminate, 
interference.
FCC RF Exposure Warning:
L This product complies with FCC radiation  exposure limits set forth for an 
uncontrolled environment. 
L To comply with FCC RF exposure  requirements, the base unit must be 
installed and operated 20 cm (8 inches) 
or more between the product and all 
person’s body (excluding extremities of 
hands, wrist and feet). 
L This product may not be collocated or  operated in conjunction with any other 
antenna or transmitter.
L The handset may be carried and operated  with only the specific provided belt-clip. 
Other non-tested belt-clips or similar 
body-worn accessories may not comply 
and must be avoided.
Notice
L FCC ID can be found inside the battery  compartment or on the bottom of the 
units.
