Chapter 1 Safety

 Recommended separation distances between portable and mobile RF

communications equipment and the SONOACE R7

This product is intended for use in an electromagnetic environment in which radiated RF disturbances

are controlled. The customer or the user of this product can help Prevent electromagnetic interference

by maintaining a minimum distance between portable and mobile RF communications equipment

(transmitters) and this product 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]

150kHz to 80MHz

80MHz to 800MHz

800MHz to 2.5GHz

V1=0.01Vrms E1=3 V/m E1=3V/m

0.01 35.00 0.11 0.23

0.1 110.68 0.36 0.73

1 350.00 1.16 2.33

10 1106.80 3.68 7.37

100 3500.00 11.66 23.33

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 of the transmitter in watts (W) according to the transmitter

manufacturer.

NOTE 1) At 80MHz and 800MHz, the separation distance for the higher frequency range applies.

NOTE 2) These guidelines may not apply in all situations. Electromagnetic propagation is aected by

absorption and reection from structures, objects and people.

 Electromagnetic environment – guidance

The Ultrasound System must be used only in a shielded location with a minimum RF shielding eectiveness

and, for each cable that enters the shielded location. Field strengths outside the shielded location from

xed RF transmitters, as determined by an electromagnetic site survey, should be less than 3V/m.

It is essential that the actual shielding eectiveness and lter attenuation of the shielded location be veried

to assure that they meet the minimum specication.

CAUTION: If the system is connected to other customer-supplied equipment, such as a local area

network (LAN) or a remote printer, Samsung Medison cannot guarantee that the remote equipment

will work correctly in the presence of electromagnetic phenomena.
