Recommended Separation Distances Between Portable And Mobile Rf Communications Equipment And The Device; Symbols - ResMed AirCurve 10 ST-A Clinical Manual

Recommended separation distances between portable and mobile RF communications
equipment and the device
The device is intended for use in an environment in which radiated RF disturbances are controlled.
The customer or the user of the device can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the device 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 determined 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.
Notes:
• At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
