The following are taken from the U.S. FDA - Center for
Devices and Radiological Health consumer update on
wireless phones.

The available scientific evidence does not show that any
health problems are associated with using wireless
phones. There is no proof, however, that wireless
phones are absolutely safe. Wireless phones emit low
levels of radiofrequency energy (RF) in the microwave
range while being used.They also emit very low levels of
RF when in the stand-by mode. 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 may occur, but such findings
have not been confirmed by additional research. In some
cases, other researchers have had difficulty in
reproducing those studies, or in determining the reasons
for inconsistent results.

Under the law, FDA does not review the safety of
radiation-emitting consumer products such as wireless
phones before they can be sold, as it does with new
drugs or medical devices. However, the agency has
authority to take action if wireless phones are shown to
emit RF energy at a level that is hazardous to the user.

Before a phone model is made available for sale to the
public, it must be tested and certified by 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., worn on the body) as required
by the FCC for each model. The highest SAR value for this
Pocket PC phone tested when being worn on the body, as
described in this User’s Guide, is 1.32 W/kg. (Body-worn
measurements differ among phone models, depending
upon available accessories and FCC requirements). While
there may be differences between the SAR levels of various
phones and at various positions, they all meet the
government requirement for safe exposure.
The FCC has granted an Equipment Authorization for this
Pocket PC phone with all reported SAR levels evaluated as
in compliance with the FCC RF exposure guidelines. SAR
information on 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 for FCC ID
PU5SP230A.
Additional SAR information can be found on the Cellular
Telecommunications & Internet Association (CTIA) web site
