ETSI Compatibility as of January 1, 2015

的 European Telecommunications Standards Institute (ETSI) has mandated a change in the way wireless products operate in the 2.4 ghz频段. This new directive, EN 300 328 v1.8.1, requires 十大正规体育平台 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频段. 的 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 2.4 ghz乐队.

 
How will this affect 十大正规体育平台 DX-Series products?

十大正规体育平台 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 .合规亚洲最大体育平台:
  • 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.
