RF emissions CISPR 11
Group 1
The Breathy uses RF energy only for its internal function. Therefore, its
RF emissions are very low and are not likely to cause any interference in
nearby electronic equipment.
RF emissions CISPR 11
Class B
The Breathy is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low-voltage
power supply network that supplies buildings used for domestic purposes.

Portable and mobile RF communications equipment should be used no

separation distance calculated from the equation applicable to the frequen

cy of the transmitter. Recommended separation distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz 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 metres (m).

should be less than the compliance level in each
frequency range. b Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2: 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 Breathy is used exceeds the applicable RF compliance level above, the Breathy should be observed
to verify normal operation. If abnormal performance is observed, additional measures my be necessary, such as re-orienting or
relocating the Breathy.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance between portable and mobile RF communications equipment and the Breathy
The Breathy is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the Breathy can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Breathy 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 metres (m) can be
estimated using the equation applicable to the frequency of the transmitter, where p is the maximum output power rating of the transmit
-
ter in watts (W) according to the transmitter manufacturer.
NOTE1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
