Guidance and manufacturer’s declaration – electromagnetic immunity
The Programmer System is intended for use in the electromagnetic environment specified below. The customer or
the user of the Programmer System 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 Programmer System,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.

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,
a
should be less than the
compliance level in each frequency range.
b
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.
a
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 Programmer
System is used exceeds the applicable RF compliance level above, the Programmer System should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the Programmer System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
