The Ameda Penguin Warmer is intended for use in an
electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Ameda Penguin

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.

electromagnetic site survey should be considered. If the measured
field strength in the location in which the Ameda Penguin Warmer is
used exceeds the applicable RF compliance level above, the Ameda
Penguin Warmer should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Ameda Penguin
Warmer.

Electromagnetic environment – guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
Ameda Penguin Warmer,
including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 1,2√P
d = 1,2√P 80 MHz to 800 MHz
d = 2,3√P 800 MHz to 2,7 GHz
Where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended 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.
