FCC/IC NOTICE
This device complies with part 15 of FCC Rules and Industry Canada’s licence-exempt RSSs.
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.
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.
This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter
except Canon accessories supplied or designated for this product.
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/ISED radiation exposure limits set
forth for an uncontrolled environment and meets the FCC radio frequency (RF)
Exposure Guidelines and RSS-102 of the ISED radio frequency (RF) Exposure rules.
5.15-5.35GHz band is restricted to indoor operations only.
Frequency Tolerance:20 ppm
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 other words,
this device automatically discontinue transmission in case of either
absence of information to transmit or operational failure.
