ADMONISHMENTS
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times.
These warnings are flagged by use of the triangular alert icon (seen below), and are listed in
descending order of severity of injury or damage and likelihood of occurrence.
GENERAL SAFETY PRECAUTIONS
-
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
Warning: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically-powered equipment. To prevent electrical shock, never install or
use electrical equipment in a wet location or during a lightning storm.
Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transceiver of any digital unit or exposure to laser radiation may
result. An optical power meter should be used to verify active fibers. A protective cap or hood
MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid
the potential of dangerous amounts of radiation exposure. This practice also prevents dirt
particles from entering the adapter or connector.
Caution: This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot
(91.4 cm) minimum clearance from the antenna while the system is operating. Wherever
possible, shut down the RAN before servicing the antenna.
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails
without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent
or curved to a radius of less than 2 inches (5.1 cm).
Caution: Exterior surfaces of the RAN may be hot. Use caution during servicing.
