Immunity to interference
The UNIT is intended for operation in the electromagnetic environment
specified below.
The customer or user of the UNIT should make sure that it is used in
such an environment.
Interference immunity

Floors should be made of wood or
concrete or finished with ceramic
tiling. If the floor is covered with syn-
thetic material, the relative humidity
should be at least 30%.

Voltage dips, short inter-
ruptions and variations
of the power supply ac-
cording to
IEC 61000-4-11
Voltage dips:

300 periods at 60 Hz
The quality of the line power supply
should be that of a typical commer-
cial or hospital environment.
If the user of the UNIT requires it to
continue functioning following inter-
ruptions of the power supply, it is
recommended to have the UNIT
powered by an uninterruptible power
supply or a battery.
Magnetic field of power
frequencies (50/60 Hz)
according to
IEC 61000-4-8
30 A/m
30 A/m
Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical commer-
cial or hospital environment.
Note: U
T
is the AC supply voltage prior to application of the test level.
Portable and mobile radio equipment
must not be used within the recom-
mended working clearance from the
UNIT and its cables, which is calcu-
lated based on the equation suitable
for the relevant transmission fre-
quency.
Recommended working clearance:
