Instructions for Use / Technical Description
Ultrasonic Unit SonicWeld Rx
Guidance and manufacturer's declaration – Electromagnetic interference emission
®
The SonicWeld Rx is intended for use in an electromagnetic environment as specified below. The user
should assure that it is used in such an environment.

Conducted RF 3 V
according to 150 kHz to
IEC 61000-4-6 80 MHz
Radiated RF 3 V/m
according to 80 MHz to
IEC 61000-4-3 2.5 GHz
Note 1 At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
Note 2
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 stations and AM and FM radio and TV stations, 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 device is used exceeds the applicable RF compliance level specified above,
the device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the device.
b
Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – Guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the device
(including cables) than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance:
=
d . 1 17 P
=
for 80 MHz to 800 MHz
d . 1 17 P
=
for 800 MHz to 2.5 GHz
d . 2 33 P
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
should be less than the compliance level in each
b
frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol.
