Page 4: Safety Information
Safety information 2.1 FCC guidelines This equipment is to be used by developers for evaluation purposes only, and must not be incorporated into any other device or system. This device must not be sold to the general public. Integrators are responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. -
Page 5: Antenna Restrictions
2.1.4 Antenna restrictions An intentional radiator must be designed to ensure that no antenna (other than that furnished by the responsible party) is used with the device. Using a permanently attached antenna or an antenna that uses a unique coupling to the intentional radiator is considered sufficient to comply with the provisions of this Section. -
