Fcc Class A Compliance; Canadian Emissions Labeling Re- Quirements - Javad OMEGA User Manual

The following sections provide information on this
product's compliance with government regulations.

FCC Class A Compliance

This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
This device may not cause harmful interference, and
This device must accept any interference received,
including interference that may cause undesired op-
eration.
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful in-
terference when the equipment is operated in a com-
mercial environment.
This equipment generates, uses, and can radiate ra-
dio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. Oper-
ation of this equipment in a residential area is likely
to cause harmful interference in which case the user
will be required to correct the interference at his own
expense.
Canadian Emissions Labeling Re-
quirements
This Class А digital apparatus meets all requirements
of the Canadian Interference-Causing Equipment
Regulations.
Cet appareil numérique de la classe А respecte toutes
les exigences du Réglement sur le matériel brouilleur
du Canada.
RF Exposure evaluation for
multi-transmitter
procedures
In mobile exposure conditions, simultaneous trans-
mission MPE test exclusion applies when the sum of
the MPE ratios for all simultaneous transmitting an-
tennas incorporated in a host device, based on the
calculated power density, is ≤ 1.0, i.e.

Where Si is the Power Density on the given distance
for i=1, 2, 3.....n,
n – number of antennas transmitting simultane-
ously,
(MPE)i is the Limit of MPE for the given transmit-
ting frequency.
The
mined at the minimum test separation distance re-
quired by the operating configurations and exposure
conditions of the host device, according to the ratio
of power density to MPE limit, at the frequency of in-
terest.
Calculation of Power Density at a giv-
en distance
Power Density (S mW/cm
Where
P – Average Power input to the antenna (in mW),
a
P = P×DC
a
DC – Source-based Duty Cycle (numeric)
G – gain of the antenna in the direction of interest
relative to an isotropic radiator (numeric),
d – distance to the center of radiation of the anten-
na (in cm).
Regarding the Javad OMEGA device containing multi-
ple transmitters:
