The HME DX100 allows up to 4 full duplex or 15 push-to-transmit shared users to speak to each other via headsets without any interconnecting cables. Much better than walkie-talkies – you can seamlessly communicate in hands-free mode or have a private conversation on a secured channel. You can even use AA/rechargeable batteries, NiMH, or 12-14VDC/automotive power. Simple and expandable, the HME DX100 comes complete with everything you need for reliable, cost-effective operation for any application. Now you can mix and match two COMMUNICATOR® models: the WH200 ComLink all-in-one, wireless headset or the BP200 beltpack with your choice of plug-in headset. System Highlights: *2.4 GHz license-free operation *Digital frequency hopping spread spectrum *Portable, compact design *Flexible battery-powered operation *Expandable systemETSI Compatibility as of January 1, 2015The 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 HME 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 inteference 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 HME DX-Series products?Clear-Com has modified its HME DX-Series wireless intercom products to be v1.8.1 compliant and created new model numbers for products sold in EU countries.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.
