9.6.4 Electromagnetic immunity environment tested (part 2)
Portable and mobile RF communications equipment should be used no closer to any part of this product, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter.
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
considered.

If the measured field strength in the location in which this product
is used exceeds the applicable RF compliance level, this product
should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary,
such as reorienting or relocating this product.
Minimum separation distance shall be calculated by following
equation:
E is the immunity test level in [V/m]
d is the minimum separation in [m]
P is the maximum power in [W]
RF wireless equipment maximum output power and
separation distance tested (at 30 cm):
TETRA 400: max 1.8 W
GMRS 460, FRS 460: max 2 W
LTE Band 13 and 17: max 0.2 W
GSM 800/900: max 2 W
TETRA 800: max 2 W
iDEN 820: max 2 W
