15. ELECTROMAGNETIC COMPATIBILITY (EMC)

Electrical medical devices are subject to special precautionary measures regarding electromagnetic compatibility. This device can be affected by
other electrical devices.
This device was tested with accessories from the accessory list for electromagnetic compatibility. Other accessories can be used only if the
electromagnetic compatibility is not interfered with. Use of noncompliant accessories can cause amplified electromagnetic emissions or decreased
electromagnetic interference resistance in the device.
WARNING
Hazard due to inadequate safety distance
If high-frequency mobile communication devices are used to close to this device, malfunctions can occur that may endanger the patient.
A safety distance of at least 0.3 m (1 foot) must be maintained.
Electromagnetic environment
The device is only to be used in environments indicated in the "Intended use" section of the operating manual.
The medical device is intended only for operation in the electromagnetic environment indicated below.

Electromagnetic environment
CAUTION
The emissions characteristics of this equipment make
it suitable for use in industrial areas and hospitals
(CISPR 11, Class A). If it is used in a residential
environment (for which CISPR 11 Class B is normally
required), this equipment might not offer adequate
protection to radio-frequency communication services.
The user might need to take mitigation measures,
such as relocating or reorienting the equipment.
Electromagnetic environment
Floors made of wood, concrete or ceramic tile are
preferred. For a synthetic floor covering, the relative
humidity should be at least 30%.
The quality of the supply voltage should correspond
to that of a typical business or hospital environment.
Devices with unusually strong line-frequency
magnetic fields (transformer stations, etc.) should not
be operated near the medical device.
Near equipment marked with the following symbol,
disturbances are possible:
