RF Energy & Specific Absorption Rate (SAR)
DIGNO DUAL (YAKF-1) meets MIC* technical regulation for exposure to radio waves.
The technical regulation established permitted levels of radio frequency energy, based on standards
developed by i ndependent s cientific or ganizations t hrough periodic an d t horough ev aluation o f
scientific studies.
The regulation employs a uni t of measurement known as Specific A bsorption Rate, or SAR. S AR
limit is 2 watts/kilogram (W/kg)** averaged over ten grams of tissue.
SAR limit includes a substantial safety margin designed to assure safety of all persons, regardless of
age/health. The value of SAR limit equals international guidelines recommended by ICNIRP***.
The maximum SAR value for this mobile phone is ●●●W/kg under PHS communication and ●●
●W/kg under 3G communication.
While there may be differences between SAR levels of various phones at various positions, all meet
MIC technical regulation.
Although SAR i s d etermined a t hi ghest c ertified p ower l evel, ac tual S AR o f the ph one d uring

FCC RF Exposure Information
Your handset is a radio transmitter and receiver. It is designed and manufactured not to exceed the
emission l imits for exposure t o r adio frequency ( RF) ener gy s et by t he F ederal C ommunications
Commission of the U.S. Government.
The guidelines are based on standards that were developed by independent scientific organization
through periodic and t horough evaluation of scientific studies. The standards include a s ubstantial
safety margin designed to assure the safety of all persons, regardless of age/health.
The exposure standard for wireless handsets employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR l imit s et by t he F CC is 1.6 W/kg. T he tests are performed in
positions a nd l ocations ( e.g. at t he ear an d w orn on t he body ) as r equired by t he F CC f or eac h
model.
The highest SAR value for this model handset as reported to the FCC when tested for use at the ear
is 0.72 W/kg, and when worn on the body in a holder or carry case, is 0.58 W/kg.
Body-worn Operation: This device was tested for typical body-worn operations with the back of the
handset kept 1.0 cm from the body. To maintain compliance with FCC RF exposure requirements,
use accessories that maintain a 1.0 cm separation distance between the user's body and the back of
the handset. The use o f beltclips, h olsters an d s imilar accessories s hould not c ontain m etallic
components in its assembly.
The us e o f ac cessories t hat do not s atisfy t hese r equirements may not c omply w ith F CC RF
exposure requirements, and should be avoided. The FCC has granted an Equipment Authorization
for t his model handset w ith all r eported SAR l evels evaluated as in c ompliance with the F CC RF
emission guidelines. SAR information on this model handset is on file with the FCC and can be found
under t he D isplay Grant s ection of http://www.fcc.gov/oet/ea/ after s earching on F CC I D

developed by the independent scientific organization ICNIRP and include safety margins designed to
assure the protection of all persons, regardless of age and health.
The guidelines use a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR
limit for mobile devices is 2 W/kg and the highest SAR value for this device when tested at the ear
was ●●● W/kg*. As mobile devices offer a range of functions, they can be used in other positions,
such as on the body as described in this User Guide. In this case, the highest tested SAR value is ●
●● W/kg. As SAR is measured utilizing the devices highest transmitting power the actual SAR of
this device while operating is typically below that indicated above. This is due to automatic changes
to t he p ower l evel of the device t o e nsure i t onl y us es t he minimum l evel r equired t o r each the
