Federal Communication Commission Interference Statement

 

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. 

Industry Canada Statements

 

This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and 
(2) this device must accept any interference, including interference that may cause undesired operation of the device. 

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 HOBO MX 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.

 

NCC Statement 

經型式認證合格之低功率射頻電機,非經許可,公司、商號或使用者均不得擅自變更頻率、加大功率或變更原設計之特性及功能。

 

低功率射頻電機之使用不得影響飛航安全及干擾合法通信;經發現有干擾現象時,應立即停用,並改善至無干擾時方得繼續使用。前項合法通信,指依電信法規定作
業之無線電通信。低功率射頻電機須忍受合法通信或工業、科學及醫療用電波輻射性電機設備之干擾。

Article 12 

Without permission granted by the NCC, any company, enterprise, or user is not allowed to change frequency, enhance transmitting power or alter original characteristic as well 
as performance to an approved low power radio-frequency device. 

Article 14 

The low power radio-frequency devices shall not influence aircraft security and interfere with legal communications. If found, the user shall cease operating immediately until no 
interference is achieved. The said legal communications means radio communications is operated in compliance with the Telecommunications Act. The low power radio-
frequency devices must be susceptible with the interference from legal communications or ISM radio wave radiated devices. 

KC Statement 

해당 무선설비는 전파혼신 가능성이 있으므로 인명안전과 관련된 서비스는 할 수 없음 

Translation: 

The service related to human safety is not allowed because this device may have the possibility of the radio interference.
