Table 204: Guidance and manufacturer’s declaration –
electromagnetic immunity
The PERITONE product is intended for use in the electromagnetic environment specified below.
The customer or the user of the PERITONE product should ensure that it is used in such
an environment.
(a) Field strengths from fixed transmitters, such as base statio ns fo r radio
(cellu la r/cordle ss) tele phones and la nd mobile radios, amateur radio, AM and FM
radio broadcast and TV broadcast cannot be predic ted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be cons
id ered. If the measured field strength in the
lo cation in whic h PERITONE product is used exceeds the applicable RF
compliance le vel above, the PERITONE product should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorie nting or relo cating the P ERITONEproduct.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be le ss
than 3 V/m.
p
Portable and mobile RF communications
equipment should be used no closer to any
art of the PERITONE product, including
cables, than the recommended separation
distance calc ulated from the equation
applic able to the fr equency of the
transmitter.
Recommende d separatio n distance
d = 1.2 P (150 kHz to 80 MHz),
d = 1.2 P (80 MHz to 800 MHz),
d = 2.3 P (800 MHz to 2.5GHz),
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 le ss than the compliance le vel
in each frequency range;
(b) in terference may occur in the vicinity of
equipment marked
with the following
