The Drive Medical #15901C/15902C is intended for use in the electromagnetic environment specified below. The
customer or the user of the Drive Medical #15901C/15902C should ensure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the Drive Medical #15901C/15902C
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 80MHz to 800MHz
𝑑 = 1,2 𝑃 800MHz to 2,5MHz
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 from
fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less
than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE I At 80MHz and 800MHz 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 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 Drive Medical #15901C/15902C is used
exceeds the applicable RF compliance level above, the bed should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the Drive Medical #15901C/15902C.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V
