Do not use the stretcher in areas with active high-
frequency equipment (e.g. RF surgical instruments) and
high EM interference (e.g. shielded MRI rooms where EM
interference is high).
Avoid using the stretcher next to or in a block with other
devices, as incorrect operation may be induced. If such
use is necessary, observe both the stretcher and the
devices for normal operation.
Modifying the stretcher can cause injury and damage.
Use the stretcher only as designed by manufacturer.
No deviations from the requirements of IEC 60601-1-2 ed. 4
No other measures are known to maintain basic safety based
on EMC phenomena.
