FCC Statement˖
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 accept any
interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate
the equipment.
NOTE: 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.
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
co-located 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: 2ADBMLS6-7620A
or Contains FCC ID: 2ADBMLS6-7620A
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.
(2) This device must accept any interference received, including
interference that may cause undesired operation.
2. Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate
the equipment.
The devices must be installed and used in strict accordance with the
manufacturer's instructions as described in the user documentation
that comes with the product.

Storage Conditions
The calculated shelf life in a sealed bag is 12 months if stored between 0 °C and
40 °C at less than 90% relative humidity (RH). After the bag is opened, devices that
are subjected to solder reflow or other high temperature processes must be handled in
the following manner:
ǂ Mounted within 168 hours of factory conditions, i.e. < 30 °C at 60% RH.
ǂ Storage humidity needs to maintained at < 10% RH.
ǂ Baking is necessary if the customer exposes the component to air for over 168
hrs, baking conditions: 125ć for 8 hrs.
