Guidance and manufacturer's declaration—electromagnetic immunity
The VPAP device is intended for use in the electromagnetic environment specified below. The customer or the user of the VPAP
device should assure that the device is used in such an environment.

NOTE 1: Ut is the AC mains voltage prior to application of the test level.
NOTE 2: At 80MHz and 800MHz, the higher frequency range applies.
NOTE 3: 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 VPAP device is used exceeds the applicable RF compliance level above, the VPAP device
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the VPAP device.
b
Over the frequency range 150kHz to 80MHz, field strengths should be less than 10 V/m.
Compliance level Electromagnetic environment—guidance
±6 kV contact Floors should be wood, concrete or ceramic tile. If
±8 kV air floors are covered with synthetic material, the relative
humidity should be at least 30%.
±2 kV Mains power quality should be that of a typical
commercial or hospital environment.
Not Applicable
±1 kV differential Mains power quality should be that of a typical
mode commercial or hospital environment.
±2 kV common
mode
< 12V (>95% dip in Mains power quality should be that of a typical
240V) for 0.5 cycle commercial or hospital environment.
96V (60% dip in If the user of the VPAP device requires continued
240V) for 5 cycles operation during power mains interruptions, it is
168V (30% dip in recommended that the VPAP device be powered from
240V) for 25 cycles an uninterruptible power source.
<12V (>95%dip in
240V) for 5 sec
3 A/m Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical
commercial or hospital environment.
Portable and mobile RF communications equipment
should be used no closer to any part of the VPAP
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
3 Vrms
d = 0.35 √P 80MHz to 800MHz
10 V/m
d = 0.70 √P 800MHz to 2.5GHz
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.
