Regulatory Compliance

The ADSP-21489 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-21489 EZ-Board is currently being processed for certification

that it complies with the essential requirements of the European EMC

directive 89/336/EEC amended by 93/68/EEC and therefore carries the

“CE” mark.

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.
