RF Exposure (500C12 model)
General Statement on RF energy
Your Notebook or Tablet PC contains a transmitter and a receiver. 
When it is ON, it receives and transmits RF energy. When you 
communicate with your Notebook or Tablet PC, the system 
handling your connection controls the power level at which your 
Notebook or Tablet PC transmits.
Specific Absorption Rate (SAR) certification information
This Notebook or Tablet PC embedded with wireless WAN or 
wireless LAN is included a radio transmitter and receiver. It is 
designed not to exceed the limits for exposureto 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 a measurement known as the Specific 
Absorption Rate, or SAR. The SAR limit for mobile devices is 
2.0 W/kg and the highest SAR value for this device when tested at 
the body was 0.07 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 
the power level of the device to ensure it only uses the minimum 
level required to reach the network.
The World Health Organization has stated that present scientific 
information does not indicate the need for any special precautions 
for the use of mobile devices. The note that if you want to reduce 
your exposure then you can do so by limiting the length of calls to 
keep the mobile devices away from the head and body.
Limiting exposure to radio frequency (RF) fields
For individuals concerned about limiting their exposure to 
RF fields, the World Health Organisation (WHO) provides the 
following advice:
Precautionary measures: Present scientific information does not 
indicate the need for any special precautions for the use of the 
Notebook PC. If individuals are concerned, they might choose 
to limit their own or their children’s RF exposure by limiting the 
length of connections, or using ‘hands-free’ devices to keep your 
Notebook PC away from the head and body.
