Recommended separation distances between portable and mobile RF communications
equipment and the Z1 CPAP System
The
Z1
CPAP System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the
Z1
CPAP System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the
Z1
CPAP System 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 separa-
tion 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 transmitter in watts (W)
according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 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.
WARNING:
Please note that mobile RF communications equipment can
effect medical electrical equipment.
Wireless Quality of Service for Z1 Bluetooth Communication with
Z1
Mobile App
The
Z1
and Mobile App utilize only a very small fraction of the available bandwidth and through-
put. Based on this, the
Z1
and Mobile App are highly tolerant of reductions in wireless quality of
service and performance will not be affected until service is essentially lost; Wireless connectivity
is not part of the essential performance of the
Z1
performance. All functions of the
Z1
can be
performed on the
Z1
unit itself; The Mobile App and
Z1
are tested for coexistence with other in-
band radio frequency sources; The Bluetooth hardware module is FCC listed, and complies with
FCC PART 15 SUBPART C.
