Data Sheet

9 U.S. FCC Statement
• The module shall be only used with the external antenna(s) that has been originally tested and certified
with this module.
• The antenna must be either permanently attached or employ a ‘unique’ antenna coupler.
As long as the conditions above are met, further transmitter test will not be required. However, the host
manufacturer is still responsible for testing their end-product for any additional compliance requirements
required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
7. Label and compliance information
Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID:
2AC7Z-ESPPICOMINI” with their finished product.
8. Information on test modes and additional testing requirements
• Operation Frequency:WiFi 2412 ~2462 MHz;BT: 2402 ~ 2480 MHz
• Number of Channel:WiFi:12 ;BT: 40
• Modulation: WiFi:DSSS/OFDM ;BT:GFSK/�/4-DQPSK/8DPSK
Host manufacturer must perform test of radiated & conducted emission and spurious emission, etc.,
according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple
simultaneously transmitting modules or other transmitters in a host product. Only when all the test results
of test modes comply with FCC requirements, then the end product can be sold legally.
9. Additional testing, Part 15 Subpart B compliant
The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.247 & 15.209 and that the
host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification. If the grantee markets their product as being Part
15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall
provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with
the modular transmitter installed.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part15 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 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.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that may cause undesired
operation.
