- Telex Model BTR-80N Base Station
- 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 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.
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.
