Reference
Guidance and manufacturer's declaration - electromagnetic immunity
The ACP-8 is intended for use in the electromagnetic environment specified below.
The customer or the user of the ACP-8 should assure that it is used in such an environ-
ment.

Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the ACP-8, includ-
ing cables, than the recommended
separation distance calculated from
the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance
d = 1.2
d = 1.2 80MHz to 800MHz
d = 2.3 800MHz to 2.5GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufac-
turer and d is the recommended sepa-
ration distance in meters (m).
Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic site survey,
a
should be less than
the compliance level in each fre-
quency range.
b
Interference may occur in the vicinity
of equipment marked with the follow-
ing symbol:
NOTE 1
NOTE 2
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.

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 con-
sidered. If the measured field strength in the location in which the ACP-8 is used exceeds
the applicable RF compliance level above, the ACP-8 should be observed to verify nor-
mal operation. If abnormal performance is observed, additional measures may be neces-
sary, such as reorienting or relocating the ACP-8.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
