GUIDELINES AND MANUFACTURER'S
DECLARATION FOR ELECTROMAGNETIC
EMISSIONS (EMC)
Guidelines and manufacturer's declaration – electromagnetic emissions
Model MD 10544 is designed for operation in an environment as described below: The customer or
user of Model MD 10544 should ensure that it is operated in such an environment.
Interference emission
measurements
In line with
Electromagnetic environment guidelines
HF emissions
according to CISPR 11
Group 1
Model MD 10544 uses HF energy
exclusively for its internal operation. Therefore
its HF emission is very low and it is
unlikely that nearby electronic
devices should suffer interference.
HF emissions
according to CISPR 11
Class B
Emission of
harmonics
according to IEC 61000-3-2
Not applicable
Emission of
voltage fluctuations/flicker
according to IEC 61000-3-3
Not applicable
Model MD 10544 is intended for use in all premises
including residential areas and those that are directly
connected to public supply networks
that also supply buildings that are used for residential
purposes.
Guidelines and manufacturer's declaration – electromagnetic interference immunity
Model MD 10544 is intended for operation in an electromagnetic environment as described below: The customer
or user of Model MD 10544 should ensure that it is operated in such an environment.

± 2 kV for supply lines
± 1 kV for input and
output lines
Not applicable
The quality of the power supply should
match that of a typical business or
hospital environment.

Not applicable
The quality of the power supply should
match that of a typical business or
hospital environment. If
the user of Model MD 10544
requires continued operation even if
power supply drop-outs occur,
we recommend supplying Model MD 10544
from an uninterruptible
power supply or a battery
.
