Safety
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.
