FCC CAUTION
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
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.
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.
Radio Frequency (RF) Exposure Warning
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. 1.9GHz Wireless Pendant
Microphone, model K-STD14 has been tested and found to comply with FCC radiation exposure
limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF)
Exposure Guidelines.
Notice
FCC ID can be found on the battery compartment of the units.
