Electromagnetic Compatibility (EMC)
18.1 EMC
The Hybrid-Power control unit has been
designed to meet the EMC requirements of EN
60601-1-2
however it may still be affected by
or emit harmful radio frequency (RF) energy.
The RF emissions from the mattress control
unit are very low and are not likely to cause any
interference to nearby electronic equipment,
however interference to sensitive equipment is
still possible. Likewise if the immunity limits of
the control unit are exceeded the system may
be seen to operate abnormally.
Interference can be received from fixed
transmitters (e.g. commercial radio and
television towers) and portable / mobile RF
communications equipment (e.g. mobile
phones). Due to the increasing number of
mobile phones and other wireless devices the
possibilities of interference to the control unit
and other surrounding equipment results in
the need for special precautions to be taken
regarding EMC.
If the control unit or any alternative equipment
is found to be operating abnormally turn off
the piece of equipment that is believed to be
causing the interference (if possible) to identify
the source of the RF energy. Once identified,
mitigation measures are to be taken, such as the
separation distances being increased and/or the
device(s) being re-orientated.
The Hybrid-Power mattress system is to be
installed and put into service according to the
information provided within this section to
ensure of reliable operation, however if the
control unit continues to operate abnormally
turn off at the mains supply and contact
Drive DeVilbiss Healthcare Ltd. or your local
distributor.

Instructions for use
Only the Drive DeVilbiss Healthcare Ltd.
approved mains cable for the Hybrid-Power
control unit is to be used.
The use of an unapproved cable could result
in increased electromagnetic emissions or
decreased electromagnetic immunity of this
equipment and result in improper operation.
•
The Hybrid-Power control unit
should not be used adjacent to
or stacked with other equipment
where possible, if adjacent
or stacked use is necessary
the Hybrid-Power should be
observed to verify normal
!
operation in the configuration in
which it is to be used.
•
Portable RF communications
equipment (e.g. mobile/cordless
phones) should be used no
closer than 30 cm (12") to the
Hybrid-Power control unit or
its mains cable, otherwise
degradation of the performance
of this equipment could result.
