Clear-Com HME DX200 Wireless Intercom System provides private, secure communication. Each base station can register up to fifteen BP200 Beltpacs and/or WH220 All-in-one Wireless Headsets. Any combination of Beltpacs and/or WH220 Headsets can be registered. Four of the fifteen can transmit simultaneously. However, by connecting two or more base stations together, these numbers can be increased. For example, two base stations can support thirty Beltpacs/ Headsets, of which eight can transmit simultaneously. Beltpacs or Headsets may be used either in the push-to- talk or hands-free mode. The base station operator can stop all Beltpacs/Headsets from transmitting.
