Appendix 2: Compliance
FCC Part 15 Compliance
The following information applies to the HOBOnode Receiver.
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by Onset Computer Corporation could void the user's authority to operate
the equipment.
To comply with FCC and Industry Canada RF radiation exposure limits for general population, the HOBOnode Receiver and
the HOBOnode Repeaters must be installed to provide a separation distance of at least 20cm from all persons and must not
be co‐located or operating in conjunction with any other antenna or transmitter.
FCC Declaration of Conformity
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may
not cause harmful interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation.

This device has been designed to operate with the antennas listed above, and having a maximum gain of 15 dB. Antennas
not included in this list or having a gain greater than 15 dB are strictly prohibited for use with this device. The required
antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication.
