levels of RF energy for the general population. The guidelines are based on standards that were developed by in-
dependent scientific organizations through periodic and thorough evaluation of scientific studies. These guidelines
include a substantial safety margin designed to ensure the safety of all persons, regardless of age and health.
The exposure standard for routers employs a unit of measurement known as the Specific Absorption Rate, or SAR.
The SAR limit set by public authorities such as the Federal Communications Commission of the US Government
(FCC), or by Industry Canada, is
1.6
W/kg averaged over 1 gram of body tissue. Tests for SAR are conducted using
standard operating positions with the router transmitting at its highest certified power level in all tested frequency
bands.
Although the SAR is determined at the highest certified power level, the actual SAR level of the router while operat-
ing can be well below the maximum value. This is because the router 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 power output of the router. Before a router model is available for sale to the public, compli-
ance with national regulations and standards must be shown.
The highest SAR value for this model router when tested is
1.198
W/Kg
for use close to the body.
While there may be differences between the SAR levels of various routers and at various positions, they all meet the
government requirement for RF exposure. For body-worn operation, the router meets FCC RF exposure guidelines
provided that it is used with a non-metallic accessory with the handset at least
10
mm from the body. Use of other
accessories may not ensure compliance with FCC RF exposure guidelines.
Additional information on SAR can be found on the Cellular Telecommunications & Internet Association (CTIA) Web
site: http://www.ctia.org/
The World Health Organization (WHO) considers that present scientific information does not indicate the need for
any special precautions for use of routers. If individuals are concerned, they might choose to limit their own or their
children’s RF exposure by limiting the length of calls, or using “hands-free” devices to keep routers away from the
head and body. (fact sheet n°193). Additional WHO information about electromagnetic fields and public health are

Note: This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference to radio or television reception, which can be determined by turning the
equipment off and on. The user is encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/ TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
For receiver devices associated with the operation of a licensed radio service (e.g. FM broadcast), they bear the fol-
lowing statement:
This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not
cause harmful interference.
For other devices, they bear the following statement:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference
(2) this device must accept any interference received, including interference that may cause undesired operation.
Your router is equipped with a built-in antenna. For optimal operation, you should avoid touching it or damaging it.
As routers offer a range of functions, they can be used in positions other than against your ear. In such circumstanc-
