Q-Series Safety Instructions

DO
Microwave Radiation
Regulations concerning microwave radiation may vary from country to country. Users are
urged to become informed, and comply with, local regulations in the country where the com-
munications equipment is used. A general recommendation is to not stand in the direction of
transmission (near or in front of the antenna) during transmission.
WARNING
An example of a radiation hazard zone for the Q-Series at maximum EIRP is calculated based
on the guidelines of the American FCC and EU directive regarding electromagnetic fields. The
zone includes the area that should be cleared of people, due to the levels of microwave radia-
tion that might be present. This does not mean that the area just outside the zone is free from
microwave radiation, but levels should not pose a danger for anyone temporarily in the area.
The calculations indicate that:
• At the back of the antenna, there is no radiation hazard, but the area should be shielded to pre-
vent touching the reflector surface or rim.
• To the side of the antenna, no radiation hazard exists outside 0.5 m from the rim of the reflector
dish (above and below the dish 0.3 m).
• As a general rule, a distance of 1.2 m from the Q-Series (sideways) is recommended, as indi-
cated on each unit. In front of the antenna, the safety distance will change, depending on eleva-
The safe operation of a DataPath system and the associated SatCom
solution, depends on thorough understanding of the safety and security
hazards, and how to mitigate or avoid them, using the precautions listed
here.
Do not use the DataPath system unless you have familiarized
yourself with this chapter!
Always maintain at least the minimum recommended distances from the antenna,
based on the elevation angle, as illustrated in Figure 1.
Under no circumstances should the system be tested with transmission
indoors or near reflective surfaces such as walls.
