Telex Model BTR-80N Base Station  Owners / Users Manual (Preliminary Information)  General Description:  The Telex model BTR-80N base station transceiver is a component of the BTR-80N wireless intercom system. The BTR-80N is a rack mountable, full duplex, wireless intercom radio for use in a professional installation such as television or cinema production.  Each BTR-80N base station can be used with one to four TR-80N or TR-82N beltpacks.  The BTR-80N transmits within the 482 to 608 MHz range (TV Channels 16-36).  It receives in the 614 to 722 MHz range  (TV Channels 38-55).  The BTR-80N transmitters operate within an 18 MHz wide section of the transmit frequency range.  The receiver also operates with a single front-end that is 18MHz wide and then block down-converts the received frequencies to four IF strips.  The RF coverage range of the BTR-82N communicating to beltpacks may be up to 200 meters (656 ft).  The transmitters have three selectable conducted output power levels; Off, 10mW, 50mW, 100mW and 249mW.  This user selectable power level allows intermodulation reduction plus the lower of transmit power to just meet the communication link’s need.  Operating frequencies can be selected from pre-set groups or the user can select special operating frequencies within the 18 MHz wide allotments.  From the front panel LCD display and buttons the following menus may be obtained:  • Group and Channel • Transmit Frequencies • Receive Frequencies • Volume and Microphone Gain Setting • Transmit power level (Off, 10mW, 50mW 100mW, 249mW) • Receiver Squelch Level • Intercom type • Intercom input/output levels • Auxiliary input/output levels • Stage announce output level  The on/off control, talk button, talk light, low battery indicator, microphone overmod. light, audio channel 1 or 2 button and lights, auxiliary and intercom level indicator lights,  portable station connection buttons are all on the front panel.  The BTR-80N base station can be powered by 100 – 240 VAC, 50 – 60Hz, via an IEC receptacle.  The unit may also be powered via a 12 - 15VDC receptacle on the rear panel.                                 Page 1 of 5

Safety Instruction to Base Station Installers and Users  1. Use only manufacturer or dealer supplied antenna.  Antenna minimum safe distance, as calculated from the FCC requirements, is 9.4cm.  However, the FCC default for the minimum safe distance is 20cm.  Antenna gain: 1.5dBi.  2. The FEDERAL COMMUNICATIONS COMMISSION has adopted a safety standard for human exposure to RF (Radio Frequency) energy, which is below the OSHA (Occupational Safety and Health Act) limits.  3. To comply with current FCC RF Exposure limits, the antenna must be installed at or exceeding the minimum safe distance show here, and in accordance with the requirement of the antenna manufacturer or supplier.  4. Antenna substitution:  Do Not substitute any antenna for the one supplied by or recommended by the manufacturer or radio dealer. You may be exposing person or persons to harmful radio frequency radiation.  You many contact your radio dealer or the manufacturer for further instructions.  5. WARNING:  Maintain a separation distance from the antenna to person(s) of at least 20cm.  You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to ensure that the minimum separation distance (above) is maintained between the antenna and nearby persons for satisfying RF exposure compliance.  The operation of this transmitter must satisfy the requirements of the General Population/Uncontrolled Exposure Environment for work-related use.  Transmit only when person(s) are at least the minimum distance from the properly installed, externally mounted antenna.   Industry Canada The Telex BTR-80N Transmitter/Receiver base station is Certified to Industry Canada RSS-123 rules.  Licensing of Telex equipment is the users responsibility and licensability depends upon the user’s classification, user’s application and frequency selected. Telex strongly urges the user to contact the appropriate telecommunications authority for any desired clarification.  CAUTION: Any changes or modifications made to the above equipment could void the user’s  authority to operate the equipment.  Page 5 of 5
