The PERICALM™ productis intended for use in the electromagnetic environment specified below.
The customer or the user of the PERICALM™ 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
(cellula r/cordle ss) tele phones and land 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 consid ered. If the measured field strength in the
lo cation in whic h PERICALM™
product is used exceeds the applicable RF
complia nce le vel above, the PERICALM™ product should be
observed to verify
normal operatio n. If abnormal performance is observed, additional measures may be
necessary, such as reorie nting or relo cating the PERICALM™product.
(b) Over the frequency range 1 50 kHz to 80 MHz, field strengths should be le ss
than 3 V/m.

Portable and mobile RF communic atio ns
equipment should be used no closer to any
part of the
PERICALM™ product, including
cables, than the recommended separation
distance calculated from the equation
applic able to the frequency of the
transmitter.
Recomme nded separation 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 electrom
agnetic site
survey,
(a) should be le ss than the compliance le vel
in each frequency range;
(b) interference may occur in the vicinity of
equipment marked with the fo llowing
