Themodule shall be only used with the internal antenna(s) that has been originally tested andcertified with this module. As long as 3 conditions above are met, further transmitter test will notbe required. However, the OEM integrator is still responsible for testing their end-product for anyadditional compliance requirements required with this module installed (for example, digitaldevice emissions, PC peripheral requirements, etc.).Validity of using the module certification:In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination withthe host equipment is no longer considered valid and the FCC ID of the module cannot be usedon the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.End product labeling:This transmitter module is authorized only for use in device where the antenna may be installedsuch that 20 cm may be maintained between the antenna and users. The final end productmust be labeled in a visible area with the following:“Contains FCC ID: 2ACSVHF-LPT120A”.Information that must be placed in the end user manual:The OEM integrator has to be aware not to provide information to the end user regarding how toinstall or remove this RF module in the user's manual of the end product which integrates thismodule. The end user manual shall include all required regulatory information/warning as show inthis manual.This device must be kept away from all persons by 20cm or more and installations using lessdistance, or installations using antennas with gain greater than that with which this was Certified willrequire additional approvals.Antenna Specification:Type: IntegratedModel: HF-LPT120ABrand: High-FlyingGain: 1.5dBi
