Page 5: Understanding Safety Alert Messages
Understanding safety alert messages Safety alert messages call attention to potential safety hazards and tell you how to avoid them. These messages are identified by the signal words DANGER, WARNING, CAUTION, or NOTICE, as illustrated below. To avoid possible property damage, personal injury, or in some cases possible death, read and comply with all safety alert messages. -
Page 6: Safety Symbols
Safety symbols The generic safety alert symbol calls attention to a potential personal injury hazard. It appears next to the DANGER, WARNING, and CAUTION signal words as part of the signal word label. Other symbols may appear next to DANGER, WARNING, or CAUTION to indicate a specific type of hazard (for example, fire, or electric shock). -
Page 7: Antenna Installation Safety
• Striking or cutting underground cables, pipes, or electric lines can cause personal injury or property damage. Only Hughes-certified installers may install or service Hughes antennas and their components. Installers must expressly acknowledge the Hughes requirements for Hughes installations. Antenna installation safety... - Page 8 • Do not work in high wind or rain, or if a storm, lightning, or other adverse weather conditions are present or approaching. • Do not attempt to assemble, move, or mount the antenna on a windy day. Even a slight wind can unexpectedly create sudden strong forces on the antenna surface.
- Page 9 • The antenna must be mounted such that no object that could reasonably be expected to support a person is within 6 ft 7 inches of the edges of a cylindrical space that projects outward from the antenna reflector toward the satellite and has the same diameter as the reflector.
- Page 10 If the antenna or mount assembly begins to fall during the installation, do not attempt to catch it . Move away and let it fall. Note: Some installations may require additional precautions. See the appropriate site preparation and mount installation guide for more information. Antenna installation safety 1039384-0001 Revision C...
