The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated as in
compliance with the FCC RF exposure guidelines. SAR information on this model phone is on file with the FCC and
can be found under the Display Grant section of www�fcc�gov/oet/ea/fccid after searching for FCCID: 2ACCJN033
for 4053S.
Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while
operating can be well below the maximum value. This is because the phone is designed to operate at multiple
power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless
base station antenna, the lower the power output of the phone. Before a phone model is available for sale to the
public, compliance with national regulations and standards must be shown.
The highest SAR value for 4053S when tested is .87W/Kg for use at the ear and 1.11W/Kg for use close to the body.
While there may be differences between the SAR levels of various phones and at various positions, they all meet the
government requirement for RF exposure.
For body-worn operation, the phone meets FCC RF exposure guidelines provided that it is used with a non-metallic
accessory with the handset at least 15 mm from the body. Use of other accessories may not ensure compliance with
FCC RF exposure guidelines.
Additional information on SAR can be found on the Cellular Telecommunications & Internet Association (CTIA) Web
site: http://www�ctia�org/
The World Health Organization (WHO) considers that present scientific information does not indicate the need for
any special precautions for use of phones. If individuals are concerned, they might choose to limit their own or their
children’s RF exposure by limiting the length of calls, or using “hands-free” devices to keep phones away from the
head and body. Additional WHO information about electromagnetic fields and public health are available on the
