For Your Safety 136
value. Because the device is designed to operate at multiple power levels 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. Before a device model
is available for sale to the public, it must be tested and certified to the FCC that it
does not exceed the limit established by the government-adopted requirement for
safe exposure. The tests are performed in positions and locations (e.g., at the ear
and worn on the body) as required by the FCC for each model.
The highest SAR values are:
• Head: 1.02 W/kg
• Body (Body-worn/Hotspot): 1.28 W/kg
(Body measurements differ among device models, depending upon available
accessories and FCC requirements).
While there may be differences between SAR levels of various devices and at
various positions, they all meet the government requirement for safe exposure.
The FCC has granted an Equipment Authorization for this model device with all
reported SAR levels evaluated as in compliance with the FCC RF emission guidelines.
SAR information on this model device is on file with the FCC and can be found under
the Display Grant section of
http://www.fcc.gov/oet/fccid
after searching on FCC ID
ZNFQ710US.
Additional information on Specific Absorption Rates (SAR) can be found
on the Cellular Telecommunications Industry Association (CTIA) website at

.
* In the United States and Canada, the SAR limit for mobile phones used by the
public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard
incorporates a substantial margin of safety to give additional protection for the
public and to account for any variations in measurements.
FCC Hearing-Aid Compatibility (HAC)
Regulations for Wireless Devices
On July 10, 2003, the U.S. Federal Communications Commission (FCC) Report and
Order in WT Docket 01-309 modified the exception of wireless devices under the
Hearing Aid Compatibility Act of 1988 (HAC Act) to require digital wireless devices
be compatible with hearing-aids. The intent of the HAC Act is to ensure reasonable
access to telecommunications services for persons with hearing disabilities.
While some wireless devices are used near some hearing devices (hearing aids
and cochlear implants), users may detect a buzzing, humming, or whining noise.
