Hearing Aid Compatibility With Mobile Phones - Sharp PV300G Reference Manual

The available scientific evidence does not show that any health problems are
associated with using low power wireless devices. There is no proof,
however, that these low power wireless devices are absolutely safe. Low
power Wireless devices emit low levels of radio frequency energy (RF) in the
microwave range while being used. Whereas high levels of RF can produce
health effects (by heating tissue), exposure to low-level RF that does not
produce heating effects causes no known adverse health effects. Many
studies of low-level RF exposures have not found any biological effects.
Some studies have suggested that some biological effects might occur, but
such findings have not been confirmed by additional research. In the United
States and Canada, the SAR limit for mobile devices used by the public is
1.6 watts/kg (W/kg) averaged over one gram of tissue. The FCC has granted
an Equipment Authorization for this wireless device with all reported SAR
levels evaluated as in compliance with the FCC RF emission guidelines. SAR
information for this 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: APYNAR0065 for the PV300G model (850/900/1700/1800/1900/2100
MHz).
For body-worn operation, to maintain compliance with FCC RF
exposure guidelines and IC RF exposure rules, keep the PV300G at
least 5/8 inch (15 mm) away from the body, and only use the carrying
cases, belt clips, or holders that do not have metal parts and that
maintain at least 5/8 inch (15mm) separation between the PV300G
and the body. When carrying the device on your person, it is
recommended to turn the screen display in toward the body in order
to minimize RF exposure and maximize antenna efficiency.

Hearing Aid Compatibility with Mobile Phones

When some mobile phones are used near some hearing devices (hearing
aids and cochlear implants), users may detect a buzzing, humming, or
whining noise. Some hearing devices are more immune than others to this
interference noise, and phones also vary in the amount of interference they
generate.
The wireless telephone industry has developed ratings for some of their
mobile phones, to assist hearing device users in finding phones that may be
compatible with their hearing devices. Not all phones have been rated.
Phones that are rated have the rating on their box or a label on the box.
The ratings are not guarantees. Results will vary depending on the user's
hearing device and hearing loss. If your hearing device happens to be
vulnerable to interference, you may not be able to use a rated phone
successfully. Trying out the phone with your hearing device is the best way
to evaluate it for your personal needs.
