Declaration Regarding Electronic Immunity
The Giraffe/Panda Warmer is intended for use in the electronic environent specified below. The user of the
Giraffe/Panda Warmer should ensure that it is used in such an environment.
Electromagnetic Immunity
Immunity Test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
IEC 60601-2-21
Note 1: Portable and mobile equipment can affect medical electronic equipment.

Appendix B: Electromagnetic Compatibility
Electromagnetic Environment Guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the Giraffe/Panda Warmer,
including cables, than the recommended
separation distance calculated from the
equation applicable for the frequency of
the transmitter.
Recommended Separation Distance
d = 1.2√ P
Radiated RF can affect the accuracy of in-
bed-scale readings. However, the in-bed-
scale is not critical to the performance of
the Giraffe/Panda Warmer unit. (Refer to
"NOTE 1" on page B-3.)
d = 1.2√ P= 26 MHz to 800 MHz
d = 2.3√ P= 800 MHz 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 meters (m).
Field strengths for fixed RF transmitters as
determined by an electromagnetic site
survey (refer to "NOTE a" on
should be less than the compliance level in
each frequency range (refer to "NOTE b" on
page B-4).
Interference may occur in the vicinity of
equipment. Marked with the following
