Bio Compression Systems SC-3004-DL Operating Instructions Manual page 18

The model SC-3004-DL is intended for use in the electromagnetic environment specified below. The customer or the user of the model SC-3004-DL should assure
that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 15 kHz to 80 MHz
Radiated RF 3 V/m
80 MHz to 2.5 GHz
IEC 1000-4-3
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply to all situations. Electromagnetic propagations is affected by absorption and reflections from structures, objects and peo-
ple.
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 model SC-3004-DL is used exceeds
the applicable RF compliance level above, the model SC-3004-DL should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the model SC-3004-DL.
b
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 model SC-3004-DL
The model SC-3004-DL is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer of user of the model
SC-3004-DL can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the model SC-3004-DL as recommended below, according to the maximum output power of the communications equipment.

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 80 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.
Guidance and manufacturer's declaration — electromagnetic immunity
Compliance level
3 Vrms Portable and mobile RF communications equipment should be used no closer to any part of the
model SC-3004-DL, than the recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
3 V/m
Recommended separation distance
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 frequency range.
