Only use approved accessories. 

 

For pluggable equipment, the socket-outlet 
shall be installed near the equipment and shall 
be easily accessible. 

 

Don’t rely on your phone as a primary device 
for emergency communications.   

 

 

 

 

 

 

 

 

 

 

 

 

 

Specific Absorption Rate (SAR)

Your mobile device is a radio transmitter and receiver. It

 

is designed not to exceed the limits for exposure to radio

 

waves recommended by international guidelines. These

 

guidelines were 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

 

Specific Absorption Rate, or SAR. The SAR limit for

 

mobile devices is

 

1.6

 

W/kg and the highest SAR value for

 

this device

 

when tested at the head was

 

1.169

 

W/kg*,

 

and

 

when tested at the body was

 

0.589

 

W/kg*

 

with

 

15

 

mm distance. As mobile devices offer a range of
functions, they can be used in other positions, such as on

 

the body as

 

described in the user manual**.

As SAR is measured utilizing the device’s highest

 

transmitting power, the actual SAR of this device while

 

operating is typically below that indicated above. This is

 

due to automatic changes to the power level of the device

 

to ensure it only uses the minimum power required to
communicate with the network.

* The tests are carried out in accordance with

 

IEEE

1528-2013, ANSI C95.1:1992, IEEE C95.1:1991.

** Please see body worn operation

 

in the user manual.
