Use of Sony wireless devices is regulated by the Federal Communications Commission as described in Part 74 subpart H of the FCC regulations and users authorized thereby are required to obtain an appropriate license. You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment. IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user's authority to operate this device. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. FCC Radiation Exposure Statement:
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 to 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. Notice for customers in Canada:
Use of Sony wireless devices is regulated by the Industry Canada as described in their Radio Standard Specification RSS-123. A license is normally required. The local district office of Industry Canada should therefore be contacted. When the operation of the device is within the broadcast band, the license is issued on no-interference, no-
protection basis with respect to broadcast signals. Operation of this device 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. The term IC: before the radio certification number only signifies that Industry Canada technical specifications were met. IC Exposure of Humans to RF Fields The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada's website:

Notes on Microphone System Operations Inserting into the supplied soft case Insert the unit into the supplied soft case with the rear side up, and close the flap.
To operate with two or more channels, maintain a distance of at least 30 cm (one ft.) between each pair of transmitters.
Ensure that the tuners set to channels not being used are either turned off or set to the minimum output level.
When turning the transmitter on or off, to keep the noise to a minimum, turn down the audio output level from the tuner or mixer to a minimum level.
Turning on the transmitter without checking the channel selection first may interfere with the operation of other microphones/transmitters, if the current setting is already being used.
To prevent noise generation, set the RF output power level to L (50 mW) when multiple channels are used simultaneously, and keep the transmitters at least 6 m (20 feet) away from the antennas.
When there is a strong interference signal around the microphone system, such as an interference caused by an active cellular phone, noise may occur on the microphone system.
Before attaching/detaching the microphone or cable, turn down the volume of the equipment connected to the tuner. Otherwise, noise will be produced.
