Portable and mobile HF communications equipment should
be used no closer to the KaWe MedCenter® 5000 (including
its power cords) than the recommended separation distance.
The separation distance is calculated using various equations
depending on the transmission frequency.
Recommended separation distance:
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 GHz
“P” is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer. “d”
is the recommended separation distance in meters (m).
Field strengths from fixed transmitters, as determined by an
electromagnetic survey of the site are less than the COMPLI-
ANCE LEVEL in each frequency range.
Interference may occur in the vicinity of equipment marked
with the following symbol:
NOTE 1: For 80 MHz and 800 MHz, the larger of the two values applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted with accuracy in theory. It is recommended that in order to assess the
ELECTROMAGNETIC ENVIRONMENT caused by fixed HF transmitters, an electromagnetic site survey should be conducted. If the measured
field strength at the location at which the KaWe MedCenter® 5000 is used exceeds the applicable compliance level stated above, the equip-
ment should be checked at each of its locations of use in order to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the KaWe MedCenter® 5000.
For frequencies ranging from 150 kHz to 80 MHz, the field strength is less than 3 V/m.
Recommended Separation Distances Between Portable and Mobile HF Communications Equipment and the
Wall Station KaWe MedCenter® 5000
The KaWe MedCenter® 5000 is intended for use in an ELECTROMAGNETIC ENVIRONMENT in which radiated HF disturbances are controlled.
The customer or the user of the equipment can help prevent electromagnetic interference by ensuring that the minimum distance
(shown below) between communications equipment (transmitters) and the KaWe MedCenter® 5000 is maintained. The minimum distance
is dependent on the maximum output power and the frequency of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance can be determined using the
equation applicable to the frequency of the transmitter. P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
NOTE 1: An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the frequency bands
between 80 MHz and 2.5 GHz in order to decrease the likelihood that mobile/portable communications equipment could cause interference
if they are inadvertently brought into PATIENT areas.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
