C-3Girae Warmer
International Electronic Commission (IEC) guidance and manufacturer’s
declaration regarding electronic immunity
The Girae warmer is intended for use in the electronic environment specied below. The user of the
Girae warmer should ensure that it is used in such an environment.
Electromagnetic immunity
Immunity Test
IEC 60601 Test

Compliance level Electromagnetic environment guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the Girae warmer, including
cables, than the recommended separation
distance calculated from the equation
applicable for the frequency of the
transmitter.

Radiated RF can aect the accuracy of
in-bed-scale readings. However, the
in-bed-scale is not critical to the
performance of the Girae warmer unit
(see Note 1).
P2.1d =
= 26 MHz to 800 MHz
P3.2d 
= 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 xed RF transmitters
as determined by an electromagnetic site
survey (see Note 3a) should be less than
the compliance level in each frequency
range (see Note 3b).
Interference may occur in the vicinity of
