Warnings and Cautions
Radar and other forms of RF radiation can cause Cardiac Pacemakers to malfunction. If you
use a Cardiac Pacemaker and suspect a malfunction, leave the vicinity of the radar system
immediately and seek medical advice.
Most countries accept that there is no significant radiation hazard at RF power density levels
of up to 10 mW/cm2.
WARNING! – LETHAL VOLTAGE HAZARD
Lethal voltages may be exposed when access covers are removed.
Some capacitors take several minutes to discharge their stored
voltages after the equipment is switched OFF: this is a lethal voltage
hazard. Always set the supply switch-fuse to OFF and remove the
fuses before removing the access covers of the equipment.
WARNING! – HEALTH HAZARD
When cleaning the inside of the equipment, take care not to inhale
dust. The dust is a temporary health hazard, depending on individual
allergies.
WARNING! – RADIATION HAZARD
Keep outside the hazard zone around an antenna or open waveguide
radiating power. Refer to the table below for hazard zones. When you
need to work on the Scanner Unit, make sure the radar is switched
OFF, and that both the Mains Isolator and the Scanner Control Unit
are turned to the OFF position.
Never look directly into an open waveguide.
Table 1: Hazard Zones
Antenna Length 10 mW/cm2 1 mW/cm2
1.2m X-band 1.7m 17m
1.8m X-band 1.05m 10.5m
2.4m X-band 0.75m 7.5m
2.7m S-band 0.73m 7.3m
3.7m S-band 0.55m 5.5m
WARNING! – ELECTROSTATIC SENSITIVE DEVICES (ESSDS)
The equipment contains ESSDs. Take care not to damage these
devices by discharge of electrostatic voltages.
