Host requirements
Only Hartvik Engineering AB determines what host that can use this module trough testing to
ensure the host comply to the supply voltage requirements and the host/module combination will be
tested to correspond to all the regulations noted in the module grant including RF exposure
evaluation.
The host manufacturer is responsible for compliance to any other FCC-rules that apply to the host,
this module only complies to the rules stated in the module grant.
Together with the host manufacturer a number of testmodes can be setup to further evaluate the
hosts ability to comply to all applicable FCC rules and the module approval is sustained.
Testing must be done according to FCC Modular transmitter integration guide KDB 996369 D04.
A ”Class II Permissive Change” must be filed to the FCC when a new host is approved.
