CR300 series-RF data loggers include radio options. The RF407-series frequency-hopping spread-
spectrum (FHSS) radio options include the RF407, RF412, RF422, and RF427. RF407-series are
designed for license-free use in several countries:
l
The RF407 option has a 902 to 928 MHz operating-frequency range appropriate for use in
the United States and Canada (FCC / IC compliant).
l
The RF412 option has a 915 to 928 MHz operating-frequency range appropriate for use in
Australia and New Zealand (ACMA compliant).
l
The RF422 option has an 863 to 873 MHz operating-frequency range appropriate for use in
most of Europe and some of Asia (ETSI compliant).
l
The RF427 option has a 902 to 907.5 MHz/915 to 928 MHz operating-frequency range
appropriate for use in Brazil.
NOTE:
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required to correct the
interference at his or her own expense.
Radio options cannot be mixed within a network. An RF407 can only be used with other RF407-
type radios, an RF412 can only be used with other RF412-type radios, an RF422 can only be used
with other RF422-type radios, and an RF427 can only be used with other RF427-type radios.
Throughout these instructions, RF407-series represents each of the RF407, RF412, RF422, and
RF427 radio options, unless otherwise noted. Similarly, the RF407-series standalone, or
independent radio represents each of the RF407, RF412, RF422, and RF427 models, unless
otherwise noted.
