Ultrasound System by no less than the distances
calculated/listed below:
D = 1.2 (√ P)
D = 1.2 (√ P) 80 to 800 MHz
D = 2.3 (√ P) 800 MHz to 2.5 GHz
where P is the max power in watts and D is the
recommended separation distance in meters.
Field strengths from fixed transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance levels.
Interference may occur in the vicinity of equipment
containing a transmitter.

Ultrasound System
The Site~Rite
®
8 Ultrasound System is intended for use in the electromagnetic environment in which radiated disturbances are
controlled. The customer or user of the Site~Rite
®
8 Ultrasound System can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF Communications Equipment and the Site~Rite
®
8 Ultrasound
System as recommended below, according to the maximum output power of the communications equipment.
