Regulatory Compliance
The ADSP-BF526 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-BF526 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-BF526 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: Z600ANA2.030 dated June 4,
2008.

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