Electromagnetic Immunity
The BiliBed is intended for use in the electromagnetic environment specified below. The customer or the user of the BiliBed
should assure that it is used in such environment.

NOTE 1 At 80 MHz and 800 MHz, 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.
a
Field strengths from fixed RF transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the BiliBed is used exceeds the applicable RF compliance level above, the BiliBed should be observed to verify normal
operation. If abnormal operation is observed, additional measures may be necessary, such as reorienting or relocating the BiliBed.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m

Recommended separation distance between portable and mobile RF communications equipment and the
BiliBed
The BiliBed is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the BiliBed can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the BiliBed as recommended below, according to the maximum output power of the com-
munications equipment.

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 trans-
mitter 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.

including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
