Cellular Telephone Specific Absorption
Rate (SAR) |
|
|
The SAR is a value that corresponds to the relative amount of RF energy
absorbed in the head of a user of a wireless handset. The FCC limit for
public exposure from cellular telephones is an SAR level of 1.6 watts
per kilogram (1.6 W/kg). Specific Absorption Rate (SAR) for Wireless
Phones and Devices Available at various Web sites.
The easiest way to ascertain SAR for many cellular phones is via the
FCC's links to individual manufacturers' Web sites: http://www.fcc.gov/cgb/sar/ .
On this page you will find links to most manufacturers' Web pages that
include SAR information for their phones, along with instructions on
how to search each site for SAR information.
You can also obtain SAR information on many cellular phones from the
FCC's database if you have the FCC ID number of the phone or device and
if it was produced and marketed within the last 1-2 years.
The FCC ID number is usually shown somewhere on the case of the phone
or device. In many cases, you will have to remove the battery pack to
find the number. Once you have the number proceed as follows. Go to the
following Web site: FCC ID Search .
Once you are there you will see instructions for inserting the FCC ID
number. Enter the FCC ID number (in two parts as indicated: "Grantee
Code" is comprised of the first three characters, the "Equipment
Product Code" is the remainder of the FCC ID). Then click on "Start
Search." The grant of equipment authorization for this particular
ID number should appear. Look through the grant for the section on SAR
compliance, certification of compliance with FCC rules for RF exposure
or similar language. This section should contain the value(s) for typical
or maximum SAR for your phone.
For portable phones and devices authorized since June 2, 2000 , maximum
SAR levels should be noted on the grant of equipment authorization. For
phones and devices authorized between about mid-1998 and June 2000, detailed
information on SAR levels is typically found in the "exhibits" associated
with the grant of equipment authorization. Therefore, once a grant is
accessed these exhibits can be viewed by clicking on the appropriate
entry labeled "View Exhibit."
Electronic records for FCC equipment authorization grants were initiated
in 1998. Therefore, prior to this date FCC records for grants are in
the form of paper records that are not part of our electronic database.
At this time, due to staff limitations, we are unable to routinely search
through FCC paper records to extract SAR information for grants filed
prior to mid- to late-1998.
