Note：The final soldering temperature chosen at the factory depends on additional external factors
like choice of soldering paste，size，thickness and properties of the baseboard，etc. Exceeding
the maximum soldering temperature in the recommended soldering profile may permanently
damage the module.

FCC Statement
Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
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
-- Consult the dealer or an experienced radio/TV technician for help receiver is
connected.
This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions (1)this device may not cause harmful interference, and (2)
this device must
cause undesired operation.
FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular cannot
be installed in any portable device, for example, USB dongle like transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be collocated or operating in conjunction with any other
antenna or transmitter.
This modular must be installed and operated with a minimum distance of 20 cm between the
radiator and user body.
If the FCC identification number is not visible when the module is installed inside another
device, then the outside of the device into which the module is installed must also display a
label referring to the enclosed module.
This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID:2ACOE-WG203 Or Contains FCC ID:2ACOE-WG203”
when the module is installed inside another device, the user manual of this device must
contain below warning statements;
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference.
