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 

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. 

FCC Caution: 

Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment.

Avis de conformité pour l’Industrie Canada 

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) 

l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le 

fonctionnement. 

To comply with FCC and Industry Canada RF radiation exposure limits for general population, the logger 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.
