NTT docomo Optimus LTE L-01D Instruction Manual page 233

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 wireless base station antenna, the lower
the output.
Before a phone 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 U.S.
government-adopted requirement for safe exposure.
The tests are performed on position and locations (for
example, at the ear and worn on the body) as required
by FCC for each model. The highest SAR value for
this model phone as reported to the FCC when tested
for use at the ear is 0.30 W/kg, and when worn on the
body, is 0.55 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 U.S. government requirement.
The FCC has granted an Equipment Authorization for
this model phone with all reported SAR levels evaluated
as in compliance with the FCC RF exposure guidelines.
SAR information on this model phone is on file with the
FCC and can be found under the Display Grant section
at http://transition.fcc.gov/oet/ea/fccid/ after search on
FCC ID ZNFL01D.
For body worn operation, this phone has been tested
and meets the FCC RF exposure guidelines when used
with an accessory designated for this product or when
used with an accessory that contains no metal and that
positions the handset a minimum of 1.0 cm from the
body.
* In the United States, the SAR limit for wireless
mobile phones used by the public is 1.6 watts/
kg (W/kg) averaged over one gram of tissue.
SAR values may vary depending upon national
reporting requirements and the network band.
