Design Considerations of EMW3239
7. FCC Statement
When this modular approved transmitter is integrated into a final host device, and the FCC ID is not visible
from the outside, than the host device must be labeled with an auxiliary label stating
“Contains FCC ID: P53-EMW3239”.
from the outside, than the host device must be labeled with an auxiliary label stating
“Contains FCC ID: P53-EMW3239”.
Following statement shall be placed on the final host device:
“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.”
When the device is so small or for such use that it is not practicable to place this statement on it, the
“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.”
When the device is so small or for such use that it is not practicable to place this statement on it, the
statement shall be placed in a prominent location in the instruction manual supplied to the user.
The user manual or instruction manual for an intentional or unintentional radiator shall caution the user
that changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
In addition, Class B digital devices shall have following statement in the user manual:
“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:

Important Notes:
After integrating this modular approved transmitter according to these instructions in this manual,
following points have to be considered:
After integrating this modular approved transmitter according to these instructions in this manual,
following points have to be considered:
- The end-product incl. this modular approved transmitter must comply with the FCC regulations.
The host manufacturer/integrator is required to show compliance with 15B (§15.107 + 15.109) while
the module is installed and operating. In addition, the module should be transmitting and the
evaluation should confirm that the module’s intentional emissions (15 C) are still compliant
(fundamental and out-of-band emission). Verify that there are no additional unintentional emissions
other than what is permitted in 15B or emissions compliant with the transmitter rule. Any additional
non-compliant emissions are unintentional which means that the host is not compliant.

- Additional antennas may be used with this modular approved transmitter, provided they are from
same type, have equal or less gain and have identical in- and outband characteristics as the certified
ones. Other antenna types or antennas with higher gain require appropriate equipment authorization.

- Due to its output power the integration is strictly limited into mobile/fixed categorized host devices
and the user manual of the host device has to include appropriate RF exposure information/warning.
