8.1 FCC Operating Requirements in North America
Customer should make sure that maximum power setting i.e PA7 is only used between CH06-65. For Channels
outside CH No. 06-65 i.e CH No. 01-04 and 66-79 the maximum power level allowed is PA3. Any configuration other
than what’s mentioned above will violate the FCC grant issued for this hardware.
8.2 ETSI Operating Requirements for EU
Device can operate between CH No. 01-79 only with Power setting equal or below PA3. Using any setting above PA3
will violate the ETSI regulations for max output power.
9 RF Exposure Requirements
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer
than this distance is not recommended.
The antenna is integrated in the module and has been qualified and approved for use under the Approval certification. This antenna
may not be modified or altered in any way from the original design as represented by Artaflex Inc.
The integrated antenna has been specifically tested with the AWAC24U, and certified through the regulatory agencies in the US,
Canada, and European Union for authorized use. Use of an altered antenna in the AWAC24U will void certification. Changes or
