. Safety
Any personnel involved in installation, operation or service of Allgon
repeaters must understand and obey the following:
•
Allgon 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
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 contains dangerous voltage that can cause
electric shock. Disconnect the mains prior to any work in the 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
•
Repeaters equipped with an optional remote communication control
unit (RCC) have a dummy load in the directional coupler (DCC) that
contains beryllium oxide (BeO). Beryllium oxide is poisonous if present
as dust or smoke which can be inhaled. Do not file, grind, machine, or
treat this part with acid.
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.
•
A lithium battery is permanently mounted on the repeater board. Due
to the risk of explosion, this battery must only be removed from the
board by an Allgon authorized service technician.
