The easy-to-use HME DX200 System comes complete with synthesized voice prompts, rechargeable batteries, battery charger and rugged, lightweight COMMUNICATOR®s for reliable and cost-effective operation. With digital encryption and frequency-hopping technologies, you'll never have to worry about unauthorized users hearing your conversation. 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. Up to 15 COMMUNICATORs can be assigned to each base station, any four of which can be used in hands-free, full-duplex mode, and a 5th when the base station headset is used. Expandable system enables up to 4 base stations to be used together for a total of 60 COMMUNICATORs with up to 16 in full-duplex, single channel mode. 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 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.
