Regulatory Compliance
The ADSP-21479 EZ-Board is designed to be used solely in a laboratory
environment. The board is not intended for use as a consumer end prod-
uct or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The ADSP-21479 EZ-Board has been certified to comply with the essen-
tial requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.
The ADSP-21479 EZ-Board has been appended to Analog Devices, Inc.
EMC Technical File (EMC TF) referenced DSPTOOLS1, issue 2 dated
June 4, 2008 and was declared CE compliant by an appointed Notified
Body (No.0673) as listed below.
Notified Body Statement of Compliance: Z600ANA2.036, dated

The EZ-Board evaluation system contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent dam-
age may occur on devices subjected to high-energy discharges. Proper ESD
precautions are recommended to avoid performance degradation or loss of
functionality. Store unused EZ-Boards in the protective shipping package.
