General Description The HME System 800 is a UHF Wireless Intercom System which provides hands»iree (full-duplex) communication with up to four belt-pass. or push-to-talk (hall-duplex) com- munication With an unlimited number of belt-pacs. Combining lull and hall-duplex, up to three wireless belt-pacs can be operated in the lull-duplex mode with an unlimited number in the halt-duplex mode. The BHBOO Belt-Pat: COMMUNICATOR®5 transmit to and receive communication from the RWBOO Base Station. An auxiliary input on the RWBOO Base Station allows everyone using the System 800 to hear cues from a mixer or other sound equipment. A cabled intercom can also be connected to the base station. and can be operated in combination with the wireless system. The RWBOO's modular construction simplifies service and expansion ol the system. C. Special Features ' Loop-around sidetones are desrgned into the system to assist in maintaining reliable com- munication among belt-pac stations. The sidetones ensure that your own voice. as you hear it in the headset. is being received at the base station and heard by other belt-pac users. it you do not hear your own voice in your headset, no one else can hear it ' The system is companderizeo to ensure clean. low-noise operation. ' Two System 8005 can be linked to provide up to eight wireless belt-pacs in the iull-duplex operating mode Three System 8005 provide up to twelve wireless belt-pacs. ' Suoaudible—lone coding is utilized in both transmission directions to prevent outside inter- lerence. ' A twoway beltclip has been designed to allow the user to either place the belt clip in the down position and secure it with two screws lor normal-clip operation. or place the belt clip in the up Dos-tron and secure it with two screws lor use With a webbed belt or equrvalent. - Electret or dynamic microphone headsets can be used with the beltoacs and/or base stations.

Full-Duplex Full~duplex operation provides continuous twcrway communication between the base station and BHBOO Belt~Pac COMMUNICATOHes, The Communicators each transmit to the base station on independent irequencies. represented by channels A thru 0 on the base station. Half-Duplex Halt—duplex operation provides push-to-talk (PTI’) communication between the base sta— tion and an unlimited number oi Communicators. The Communicators typically all transmit to the base station on the same channel/irequency. since only one Communicator can transmit at a time. an unlimited number at Communicators can be set up on any of the channels ior this type operation However, it one operator pushes the PTI' button on his/her Communicator while the PT'I' button on another Communicator on the same channel is being pushed, interference will occur Combined Full and Half-Duplex Combined operation permits use with any number of belt-pacs in the halt-duplex mode. and up to three bett-pacs in full-duplex. In combined use. one channel is designated ior hall-duplex, and the three remaining channels are used for iulI-duplex operation. All of the FlWBOO Base Station functions still apply. and the sidetone capability is maintained. VI. INSTALLATION AND OPERATION A.
