Chapter 7 Working environment and maintenance
Suitable working environment and proper maintenance
methods can extend service life of the equipment
effectively. For maintenance please read the contents of
this section carefully.
7.1 Public areas
In public areas ensure that the cables attached to the
system units, including extension cables, are run and laid
out in a neat and tidy manner where they do not interfere
and hinder public walk ways.
It is recommended that the chairman unit and the
interpreter units are connected at the beginning of a
trunk line and not at the end. In public areas where
connectors and cables could be trampled on, it is
strongly suggested to use protective covers according to
the existing protection specifications.
Due to the directivity of the microphone used in the
discussion units, every speaker should face the
microphone at a convenient distance when speaking, to
achieve both best audibility and intelligibility.
The texture of optical fiber cable is crisp, with low
mechanical strength. A little carelessness may cause
broken. Therefore, when cabling, please pay particular
attention to:

Terminating and maintenance of optical fiber
should be carried out by strictly trained technical
staff;

There must be a complete design and
construction drawings, for the convenient and
reliability for future construction and inspection;

During construction, always pay attention not to
press the optical fiber cable by weight or prick by
hard objects; In addition, traction force shall not
exceed the maximal laying tension;

When turning, the turning radius should be 20
times greater than the diameter of the cable itself;

When pulling through the wall or the floor,
protective plastic tube with protective seal should
be used, and fill the tube with flame retardant filler;
A certain amount of plastic pipelines can also be
laid inside the building;

The length of cabling shall not be too long in one
time (normally 2 KM), and start from the middle to
both sides in traction.
7.2 Technical rooms
It is recommended to meet the following conditions for
technical rooms where HCS-4100/50 central control
equipment is housed:

Ensure that the area is a dust-free environment.

Ensure adequate ventilation.

Ensure adequate lighting. But be sure that the
lighting does not impede the operator in the
control room and the normal system operation.

Do not place objects on the top of units. They
could fall into vents or could cover them and thus
prevent proper cooling of electronic components
inside the units. By falling into a unit, objects could
cause trouble such as fire and electric shock.

To avoid the risk of shock or permanent damage to
the system units, do not expose units to rain or
moisture.

Do not attempt to remove the top cover of the
system main units as you will be exposed to a
shock hazard. The covers should only be removed
by qualified service personnel. If any repair or
maintenance is required, contact the TAIDEN
service center in your region.

Equipment is only for indoor use. Do not expose it
to sunlight.
WARNING: Damage to the power cable may cause fire
or a shock hazard!
7.3 Interpreter booths
Pressure and speed of work at most international
congresses imply that interpreters have to take turns and
to turn about to keep pace and to ensure a steady flow of
smooth interpretation. Therefore every interpreter booth
has to have an adequate size to accommodate at least
two or three interpreters, depending on the present
needs. Following a brief summary, according to the
specifications for interpreter booths as drawn up in the
ISO standards:

In the hall, booths should be set up at the back or
180
