Climatronics - Model 900MHz -Spread Spectrum Radio for IMP- Series Data Loggers

The P/N 102590 Spread Spectrum Radios reduce susceptibility to RF interference from other spread spectrum devices by providing user-selectable frequency hopping patterns. The P/N 102590 Spread Spectrum Radios spread spectrum radio modems support point-to-point and point-to-multipoint data logger communications. They can serve as a field modem/radio while connected to the data logger or as a base station modem/radio when connected to a computer.

• The operating frequency band of these radio modems may be shared with other non-licensed services such as cordless telephones and with licensed services including emergency, broadcast, and air-traffic control.
• P/N 102590 Spread Spectrum Radios, like all FCC Part 15 devices, are not allowed to cause harmful interference to licensed radio communications and must accept any interference that they receive. Most Climatronics users operate in open or remote locations where interference is unlikely. If there is a problem, interference can be reduced using methods such as moving the device, reorienting or using a different type of antenna, or adding RF shielding. We recommend the use of licensed UHF or VHF narrowband frequencies for critical communication links.
