FCC Caution:
(1)Exposure to Radio Frequency Radiation. This equipment must be installed and operated in accordance with
provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other
antenna or transmitter. End-users and installers must be provided with antenna installation instructions and
transmitter operating conditions for satisfying RF exposure compliance.
(2) Any changes or modifications not expressly approved by the grantee of this device could void the user's
authority to operate the equipment.
(3) This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
(4) Changes or modifications to this unit not expressly approved by the party responsible for compliance could
void the user authority to operate the equipment.
(5) the modules FCC ID is not visible when installed in the host, or
(6) if the host is marketed so that end users do not have straight forward commonly used methods for access to
remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to
the enclosed module: Contains Transmitter Module FCC ID: UDV-2013072401 or Contains FCC ID:
UDV-2013072401 must be used.
1. SIM800H Description

Page 10: Antenna Interface
5.1 GSM Antenna Interface There is a GSM antenna pad named RF_ANT for SIM800H the connection of the antenna must be decoupled from DC voltage. This is necessary because the antenna connector is DC coupled to ground via an inductor for ESD protection. - Page 11 SIM800H Document Figure1: GSM antenna matching circuit R101 C101 C102 are the matching circuit, the value should be defined by the antenna design. normally R101 is 0 , C101 C102 are not SMD.
