14 RF Regulatory 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 used for certification of the module has been qualified and approved for use under the Modular Approval certification.
This antenna is to be compatible with the RF impedance and frequency range of the AWS24S.
The antenna has been selected and specifically tested with the AWS24S, and has been certified through the regulatory agencies in
the US, Canada, and European Union for authorized use. Use of a different antenna in the AWS24S may void the MA grant for that
AWS24S if the same parameters are not adhered to. Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this
equipment. Such modifications could void the user’s authority to operate the equipment.
For more details on the proper installation requirements please review Artaflex User Manual “UMAWS24S”.
