Guidance and Manufacturer’s Declaration—Electromagnetic Immunity
The SonixTouch Q+ Ultrasound System is intended for use in the electromagnetic environment specified below. The customer or the user of the SonixTouch Q+
should ensure that it is used in such an environment.

Portable and mobile RF communications equipment should be used no closer to any part
of the SonixTouch Q+ Ultrasound System, including cables, than the recommended
separation distance calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
80 MHz to 800 MHz
800 MHz to 2,5 GHz
where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site
survey

.
Interference may occur in the vicinity of equipment marked with the following symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the SonixTouch Q+ is used exceeds the applicable
RF compliance level above, the SonixTouch Q+ should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the SonixTouch Q+.
a Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and the SonixTouch Q+ Ultrasound System
The SonixTouch Q+ Ultrasound System is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the SonixTouch Q+ can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the SonixTouch Q+, as recommended below, according to the maximum output power of the communications
equipment.
Rated maximum output power of transmitter W
Separation distance according to frequency of transmitter m

10 3,7 3,7 7,4
100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended separation distance (d) in meters (m) can be estimated using the equation
applicable to the frequency of the transmitter, where P is the maximum output power rating in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
