Guidance and Manufacturer's Declaration—Electromagnetic Immunity
The A-71100-XX/ A-71101-XX are intended for use in the electromagnetic environment
specified below. The customer or the user of the A-71100-XX/A‑ 71101-XX should make
sure it is used in such an environment.

Note 1: At 80 MHZ and 800 MHz, the higher the frequency range applies.
Note 2: These guidelines may not apply in all cases. 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 covered by fixed RF transmitters, surveys
at the electromagnetic sites should be considered. If the measured field strength in
the location in which the A-71100-XX/A-71101-XX is used exceeds the applicable
RF compliance level above, the A-71100-XX/A-71101-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.
b. Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3
V/m.

Compliance Electromagnetic Environment—
Level Guidance
Portable and mobile radio frequency
(RF) communications equipment
should not be used adjacent to any
part of the A-71100-XX/A-71101-XX.
When used, the distance should be
greater than the recommended
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended distance:
�� = ��. ����√��
�� = ��. ����√��
3 Vrms
�� = ��. ����√��
Where P is the maximum output
power rating of the transmitter in
3 V/m
watts (W) according to the transmitter
manufacturer and d is the
recommended distance in metres (m).
It is determined through surveys at the
electromagnetic sites
strength emitted by fixed RF
transmitters should be below the
specified level for each frequency
