Table 3
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The PRO-II
® and PRO-III ® devices are intended for operation in the electromagnetic
environment specified below.
The customer or user of the PRO-II ® or PRO-III ® device must ensure that it is used in
such an environment.

Portable and mobile RF
communications equipment
should be used no closer to
any part of the PRO-II ® and
PRO-III ® devices, incl.
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 for 80 MHz to
800 MHz
d= 2.3 √P for 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
meters (m).
Field strength from fixed
RF transmitters, as
determined by an
electromagnetic site
survey a , should be lower
than the compliance level
in each frequency range. b
Interference is possible in
the vicinity of devices
bearing the symbol shown
below.
