Pre-installation Considerations
Review the following pre-in tallation con ideration before in talling a Harmony
802.11a network adapter.
Regulatory Warnings
FCC Guidelines
Model 815 8 2.11a PCI Card Users:
It i the re pon ibility of the in taller and u er of the Harmony 802.11a PCI Card
Model 8150 to guarantee that the antenna are operated at lea t 20 centimeter from
any per on. Thi i nece ary to in ure that the product i operated in accordance
with the RF Guideline for Human Expo ure which have been adopted by the Federal
Communication Commi ion.
Radio Frequency Interference Requirements
The Harmony 802.11a CardBu Card, Model 8450, and the Harmony 802.11a PCI Card,
Model 8150, operate in the frequency range of 5.15 to 5.35 GHz; they are re tricted to
indoor u e due to their operation in the 5.15 to 5.25 GHz frequency range.
FCC 15.407(e) require that the e device be u ed indoor in the frequency range of
5.15 to 5.25 GHz to reduce the potential for harmful interference to co-channel Mobile
Satellite y tem . Therefore the device hould be u ed indoor only for channel 36,
40, 44, and 48 and when 2X mode i enabled, channel 42 and 50.

In tallation 13
High power radar are allocated a primary u er of the 5.25 to 5.35 GHz and 5.65 to
5.85 GHz band. The e radar tation can cau e interference with and/or damage the
Harmony 802.11a CardBu Card and/or Harmony 802.11a PCI Card.
DECLARATION OF CONFORMITY

Industry Canada Guidelines
Model 815 8 2.11a PCI Card Users:
The Harmony 8150 802.11a PCI Card ha been de igned to operate with an antenna
having a maximum gain of 3 dBi. Antenna having a higher gain i trictly prohibited
per regulation of Indu try Canada. The required antenna impedance i 50 ohm . To
reduce potential radio interference to other u er , the antenna type and it gain
hould be o cho en that the equivalent i otropically radiated power (EIRP) i not
more than that required for ucce ful communication. The in taller of thi radio
equipment mu t en ure that the antenna i located or pointed uch that it doe not
