FCC/IC NOTICE 

HD Camcorder, XA25 / XA20 VIXIA HF G30 systems 

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. 

Note: 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 or more 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. 

Use of shielded cable is required to comply with class B limits in Subpart B of Part 15 of FCC Rules. 

Do not make any changes or modifications to the equipment unless otherwise specified in the manual. If such changes or modifications should 

be made, you could be required to stop operation of the equipment. 

Model ID0025 (including WLAN Module Model RF400, FCC ID: AZD400) 

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. 

This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. 

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no 

proof, however, that these low power wireless devices are absolutely safe. Low power wireless devices emit low levels of radio frequency 

energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of 

low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not 

found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed 

by additional research. This model has been tested and found to comply with FCC/IC radiation exposure limits set forth for an uncontrolled 

equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65 and RSS-102 of the IC radio frequency (RF) 

Exposure rules. 

 

Compliance with FCC requirement 15.407(c) 

Data transmission is always initiated by software, which is the passed down through the MAC, through the digital 

and analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the 

only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the 

packet. Therefore, the transmitter will be on only while one of the aforementioned packets is being transmitted. In
