Cordless phones: KX-TG4051/KX-TG4071/KX-TG4051C
LThis unit is pre-registered to the base unit.
LThis leaflet only describes the steps needed to install and use the unit. Refer to the 
base unit’s operating instructions for the accessory information, important 
information for safety, FCC information (for U.S.A. users only), and Industry 
Canada Notices and other information (for Canada users only).
For best performance
Placement
LWe recommend installing the unit to a raised position (such as on a wall), which is 
well within range of the base unit.
LAvoid positioning the unit close to objects that will interfere with reception, such as 
thick walls, radiators, metal shelving, etc.
LFor maximum distance noise-free operation, place the unit away from electrical 
appliances such as TV, radio, personal computer or other telephone equipment.
LKeep a minimum distance of 5 m between this unit and the base unit.
(The minimum distance may vary depending on the location.) If the unit is installed

FCC and other 
information
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 expressl
y
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 digit
a
device, pursuant to Part 15 of the FCC 
Rules. These limits are designed to provid
e
reasonable protection against harmful 
interference in a residential installation. Thi
s
equipment generates, uses, and can radiat
e
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 i
encouraged to try to correct the interferenc
e
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.

_8_
– 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.
