requirements adopted by the ACTA. A 
compliant telephone cord and modular 
plug is provided with this 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 this 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 isn’t 
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 
Servicenter 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.
