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

cause no
significant RF hazard.

Dangerous HIGH voltage inside:
Life threatening high voltage is present in the antenna and display units. This high
voltage may be present even after the power switch has been turned off. The high
voltage circuits are provided with protection covers and warning labels to avoid
unintentional contact with these sections. For safety reasons, switch the power off
