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 T770B when tested is 1.12 W/Kg for use
at the ear and 1.22 W/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://

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
may 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
