Warning, Cautions, and Notes
Warnings, Cautions, and Notes are found throughout this manual where applicable. The associated icons in
warnings and cautions are used to quickly identify a potential condition that could result in the consequences
described below if precautions are not taken. Notes clarify and provide additional information to assist the
user.

WARNING: The warning symbol means danger. You are in a situation that could cause bodily
injury or death. Before you work on any equipment, be aware of the hazards involved with elec-
trical and RF circuitry and be familiar with standard practices for preventing accidents.

Safety
Any personnel involved in installation, operation, or service of units included in a Powerwave repeater
systemmust understand and follow the points below:
systemmust understand and follow the points below:
Powerwave repeaters are designed to receive and amplify signals from one or more base stations and
retransmit the signals to one or more mobile stations. And, also to act the other way round, that is to
receive signals from one or more mobile stations, amplify and retransmit the signals to the base sta-
tions. Powerwave repeater systems must be used exclusively for this purpose and nothing else.

Units supplied from the mains must be connected to grounded outlets and in conformity with the local
prescriptions.
prescriptions.
For outdoor use, the power cord should meet at least IP65 encapsulation requirements. Do not turn the
main power on until you are ready to commission the equipment.
main power on until you are ready to commission the equipment.
Power supply units supplied from the mains contain dangerous voltage that can cause electric shock.
Disconnect the mains prior to any work in such a unit. Local regulations are to be followed when servic-
ing such units. Only authorized service personnel are allowed to service units while the mains are con-
nected.

When working on an a repeater on high ground, for instance on a mast or pole, be careful not to drop
parts or the entire repeater. Falling parts can cause serious personal injury.
All RF transmitting units, including the Nexus RT Repeater, will generate radio signals and thereby
give rise to electromagnetic fields that may be hazardous to the health of any person who is exten-
sively exposed close to an antenna.

Beryllium oxide (BeO) may be contained in power devices, for instance in dummy loads in directional
couplers (DCC), in combiner units (CMB), and in attenuators on the FON board. Beryllium oxide is poi-
sonous if present as dust or smoke that can be inhaled. Do not file, grind, machine, or treat these parts
with acid.

Coaxial cables used in many Powerwave systems have the insulation made of PTFE, polytetrafluoro
ethylene, that gives off small amounts of hydrogen fluoride when heated. Hydrogen fluoride is poison-
ous. Do not use heating tools when stripping off coaxial cable insulation. No particular measures are to
be taken in case of fire because the emitted concentration of hydrogen fluoride is very low.
