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. If not, a second label must be placed on the outside of the final device that contains the
following text：
“Contains FCC ID：
SIM340E FCC label is shown as：
UDV-0606020080701”
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
2
cm is 0.8594 mW/cm
.（850MHz）
This equipment complies with part15 of FCC Rules. Operation is subject to the
following two conditions: (1) this device may not caulse harmful interference, and
(2) this device must accep any interference received, including interference that may
cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• 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.
