The Clear-Com CP-242 is a 4-channel wireless BeltStation that operates in conjunction with the CM-244 Tempest2400 BaseStation. The Clear Com CP 242 has 3 modes of operation - Normal, Split and Shared. By switching to Shared or Split Mode, an unlimited number of BeltStations can be registered to each BaseStation using shared resources. Each BeltStation user may simultaneously Talk/Listen on A or B and C or D or toggle between A and B or C and D in ?Single Listen? mode. Volume is set the by rotating the CH A/B or CH C/D rotary control. Each full-duplex Clear Com CP-242 establishes a unique audio path (point-to-point) with the associated CM-244 BaseStation delivering an individualized mix minus signal to other BeltStations in the system. Therefore, each Clear Com CP-242 can monitor a unique mix of intercom channels and other audio sources. The CP-242 BeltStations are made of a weather-resistant ABS co-polymer blend with a high performance polyurethane over-mold. Tempest2400 Seamless Roaming is the ability for one or more Clear Com CP-242 BeltStations to move freely from one BaseStation to another without any intervention from the end user. This allows the implementation of a Tempest2400 wireless intercom system which can cover large areas with multiple zones or areas in a facility that would not be adequately supported by a single antenna installation. A Clear Com CP 242 BeltStation can roam between as many as 16 different BaseStations (coverage areas or zones). In addition, all Tempest operational modes (Normal, Shared and Split) are supported for seamless roaming.
