Guidance and manufacturer’s declaration – electromagnetic immunity (Table 4 - IEC 60601-1-2)
The telescopic pillar CPMT is intended for use in the electromagnetic environment specified below.
The customer or the user of telescopic pillar should ensure that it is used in such an environment.

Portable and mobile RF communications equipment should be
used no closer to any part of the telescopic pillar CPMT, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
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
where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is the
recommended separation distance in meters (m). Field strengths
from fixed RF transmitters, as determined by an electromagnetic
site survey
1)
, should be less than the compliance level in each
frequency range
2)
. Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
1)
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 theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the telescopic pillar CPMT is used exceeds the applicable RF compliance level above, the Model 006
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the telescopic pillar
CPMT.
2)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
telescopic pillar CPMT (Table 6 – IEC 60601-1-2)
The telescopic pillar CPMT is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or user of the telescopic pillar CPMT can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the telescopic pillar CPMT as recommended below,
according to the maximum output power of the communications equipment.
