. Safety
Any personnel involved in installation, operation or service of Allgon
repeaters must understand and obey the following:
• Allgon AR repeaters are designed to receive and amplify signals from
one or more base stations and retransmit the signals to one or more
mobile stations. Also, the repeaters are designed to receive signals from
one or more mobile stations, amplify and retransmit to the base
stations. The AR repeaters must be used exclusively for these purposes
and nothing else.
• Repeaters supplied from the mains must be connected to grounded
outlets and in conformity with any local regulations.
• The power supply unit in repeaters supplied from the mains contains
dangerous voltage that can cause electric shock. Disconnect the mains
prior to any work in such a repeater. Any local regulations are to be
followed when servicing repeaters.
Authorized service personnel only are allowed to service repeaters while
the mains is connected.
• The repeater cover must be secured in opened position, e.g. by tying it
up, at outdoor repeater work. Otherwise, the cover can be closed by the
wind and cause your fingers getting pinched or your head being hit.
• When working on a repeater on high ground, e.g. on a mast or pole, be
careful not to drop parts or the entire repeater. Falling parts can cause
serious personal injury.
• Any repeater, including this repeater, will generate radio signals and
thereby give rise to electromagnetic fields that may be hazardous to the
health of any person who is extensively exposed to the signals at the
immediate proximity of the repeater and the repeater antennas.
BERYLLIUM OXIDE
• CHA channel board power transistors, PA amplifier board power
transistors, combiners (CMB), and FON board attenuators (at the P101
port) may contain beryllium oxide (BeO) that is poisonous if present as
dust or smoke which can be inhaled.
Do not file, grind, machine, or treat these parts with acid.
Warning signs are applied on units containing beryllium oxide. These
warning signs are shown in the next section.
HYDROGEN FLUORIDE
• The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene,
that gives off small amounts of hydrogen fluoride when heated.
Hydrogen fluoride is poisonous. 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.
