3.2.8 Software Architecture 4 AT command （please see the AT command document） 5 FCC Labeling Requirement Please note： When the SIM340E is integrated into a final product, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel，door or cover is easily removed.
6 FCC RF exposure requirements The maximum measured power output is 770 mW（1900MHz）/1440mW（850MHz）, the maximum antenna gain is 3 dBi. The maximum permissible exposure is defined in 47 CFR 1.1310 with 1 mW/cm2. The transmitter is using indoor antennas that operate at 20cm or more from nearby persons. the power density at 20 cm is 0.4596 mW/cm2.（1900MHz），the power density at 20 cm is 0.8594 mW/cm2.（850MHz） This equipment complies with part15 of FCC Rules.
• • • Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.
