Exposure to radio frequency radiation
This device and its antenna must not be co-located or operated in
conjunction with any other antenna or transmitter. To comply with RF
exposure requirements, use only the supplied antenna.
The radiated output power of this internal wireless radio is far below
radio frequency exposure limits. Nevertheless, the wireless radio
shall be used as described in the manual.
The internal wireless radio operates within guidelines found in radio
frequency safety standards and recommendations, which reflect the
consensus of the scientific community.
Plantronics therefore believes the internal wireless radio is safe for
use by consumers. The level of energy emitted is far less than the
electromagnetic energy emitted by wireless devices such as mobile
phones. However, the use of wireless radios may be restricted in
some situations or environments, such as on board aeroplanes. If
you are unsure of restrictions, you are encouraged to ask for authori-
sation before turning on the wireless radio.
NOTE: Modifications not expressly approved by Plantronics, Inc.
could void the user’s authority to operate the equipment.
