Allen® Advance Table User Manual (D-720686-A6) 81
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The A-71100-XX/A-71101-XX and A-71705-XX are intended for use in the electromagnetic
environment specified below. The customer or the user of the A-71100-XX/A-71101-XX or
A-71705-XX should make sure it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the A-71100-XX/A-71101-XX or A-
71705-XX, including cables, than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance:
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 in
metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
survey

Interference may occur in the vicinity of
equipment marked with the following
symbol.
a. F
ield 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 A-71100-XX/A-71101-XX
or A-71705-XX is used exceeds
the applicable RF compliance level above, the A-71100-XX/A-71101-XX or A-71705-
XX should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating
the A-71100-XX/A-71101-XX
or A-71705-XX.
b.
Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3
V/
m.
Note 1: At 80 MHZ and 800 MHz, the higher the 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.
