APPENDIX B
MODEL 571/581 INTERNATIONAL ELECTROTECHNICAL
COMMISSION (IEC) COMPLIANCE
Meets IEC standards 801.2, 801.4 and 801.5 (CE Mark)
Effective January 1996 the European Economic Community will require that all electronic devices be tested and comply with all applicable International standards relating to the product type and category of use. Electromagnetic Compatibility Directive 89/336/EEC specifically addresses communication line surge protection devices, since conformity to immunity standard
*Note: All test results are for the Model 571/581 alone, not including the standard 6 inch (15.25) patch cable that is shipped with the unit.
