The exposure recommendations for mobile phones use a
measurement unit known as the Specific Absorption Rate
(SAR). The SAR limit recommended by the ICNIRP for the
mobile phones used by the general public is 2.0W/kg averaged
over ten grams of tissue and, is 1.6W/kg averaged over
one gram of tissue by IEEE STD 1528 for the head.
Tests for SAR have been conducted using recommended
operating positions with the mobile phone transmitting at its
highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power
level, the actual SAR levels of the mobile phone while
operating are generally below the maximum SAR 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 base station
antenna, the lower the power output.
While there may be differences between the SAR levels of
various phones and at various positions, they all meet the
international protection standards for exposure to radio
waves.
The SAR limit of USA (FCC) is 1.6 W/kg averaged
over one gram of tissue. Device types
CTW337P97706EK (FCC ID: VQRCTW337P97706EK)
has also been tested against this SAR limit. The
highest SAR value reported under this standard
during product certification for use at the ear is 0.995
W/kg and when properly worn on the body is 1.032
W/kg. This device was tested for typical body-worn
operations with the back of the handset kept 1.0cm
Safety & Precaution 30
from the body. To maintain compliance with FCC RF
exposure requirements, use accessories that maintain
a 1.0cm separation distance between the user's body
and the back of the handset. The use of belt clips,
holsters and similar accessories should not contain
metallic components in its assembly. The use of
accessories that do not satisfy these requirements
may not comply with FCC RF exposure requirements,
and should be avoided.
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.
NOTE: The manufacturer is not responsible for any
radio or TV interference caused by unauthorized
modifications to this equipment. Such modifications
could void the user's authority to operate the
equipment.
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
