radiation exposure compliance requirements, a separation distance of at least 2.5 cm (1.0 inch) must be
maintained between the antenna of the device and all persons.
The installer of this radio equipment must ensure that the antenna is located or pointed such that it does
not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6,
obtainable from Health Canada’s website www.hc-sc.gc.ca/rpb.
This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment. End
users must follow the specific operating instructions for satisfying RF exposure compliance. This equipment
should be installed and operated with minimum distance 2.5cm between the radiator and your body.
This product must maintain a minimum body to antenna distance of 2.5 cm. Under these conditions this
product will meet the Basic Restriction limits of 1999/519/EC [Council Recommendation of 12 July 1999 on
the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz)].
