OPERATOR SAFETY
Watch for the rotating antenna:
The radar antenna will start to rotate without notice. For your safety, keep away from
the area in the vicinity of the radar antenna.
Be aware of RF Radiation Hazard:
The active radar antenna radiates powerful RF energy. Continuous exposure to RF
energy may cause harmful effects to the human body. It also causes Cardiac
Pacemaker to malfunction. A person who uses a Cardiac Pacemaker should under no
circumstances be exposed to RF radiation.
Most countries accept that RF power density levels below 100 W/m
significant RF hazard.
