Table 5.8 - Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The PachPen is intended for use in the electromagnetic environment specified below. The
customer or the user of the PachPen should assure that it is used in such an environment.

N/A
Portable and mobile RF
communications equipment should
be used no closer to any part of the
PachPen, 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 = 1.2√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
metres (m). Field strengths from fixed
RF transmitters, as determined by an
electromagnetic site survey,

should
be less than the compliance level in
each frequency range.

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