ETSI Compatibility as of January 1, 2015

The European Telecommunications Standards Institute (ETSI) has mandated a change in the way wireless products operate in the 2.4GHz bands. This new directive, EN 300 328 v1.8.1, requires Clear-Com to modify its DX-Series wireless intercom products and ship only v1.8.1 compliant products into countries that require CE compliance, beginning January 1, 2015.

What is EN 300 328 v1.8.1?

A new ETSI standard to address interference issues within the 2.4GHz ISM band.

The main changes relate to how devices communicate and allocate radio space when they are in the same area. A new “adaptive mode” is required, which provides a mechanism so equipment can adapt to its environment by identifying other transmissions present in the 2.4GHz band.

How will this affect Clear-Com DX-Series products?

Clear-Com has modified its DX-Series wireless intercom products to be v1.8.1 compliant and created new model numbers for products sold in EU countries.

New HME DX-Series EU Model Numbers available here.

How do I determine if my BP200, BP 210, WH200, WH220 will work with new EU compliant base stations?
Check the G number, which is located on label under the battery, and cross reference to chart above.

Characteristics of new v1.8.1 compliant product:

  • Spectrum-friendly feature will no longer be available.
  • New beltpacks will be backwards compatible with older versions of the base stations.
  • Older versions of beltpacks will not work with new base stations.
  • Testing is more important when installing in order to determine antenna placement and coverage area, particularly when other 2.4GHz equipment is nearby.
