TS-800/900
Infrared Wireless Conference System
COOKBOOK
GENERAL DESCRIPTION
(1) Objectives
• With the aim of enhancing the lineup of the TS-700 Series currently on the
market, two series of conference system that employ the infrared
communication method are offered.
• Like the TS-700 Series, the new series target small-scale, temporary, or
committee meeting conference rooms. Designed to meeting the
requirements arising from recent merger wave among municipalities, they
are most suitable for new installation at city halls as well as tentative
installation needs to cope with a temporary increase in the number of
assemblymen at the time of the merger.
• The TS-800 Series represents a cordless version of the TS-700 Series.
Thus, its functions are almost identical with those of the TS-700.
• The TS-900 Series, a high-end model, is equipped with additional
functions such as a voting function.
General Description
(2) Wh y infrared comm unication method?
• The infrared communication method frees users from worries about
eavesdropping and radio interference inherent to radio wave-based
wireless communications.
• Place a single wall in between, and what is being discussed in the
conference room will never be heard outside. For the same reason,
it is possible to use two or more systems simultaneously in adjoining
conference rooms.
(3) Advantages of the cordless system
• Installation work is simplified. Wiring between the Central unit and the
Transmission/Receiver unit is all that's necessary. Wiring is easily done
with a single coaxial (BNC-BNC).
•A cordless system allows easy system installation and removal, greatly
reducing the workload associated with relocation and layout changes.
• Because no wiring to the conference units is necessary, the system is free
from troubles, such as deterioration and a break in the wiring, that are
caused by repeated installations and removals.
• The Transmitter/Receiver unit can be mounted on a microphone stand, to
create a tentative system without requiring installation work.

GENERAL DESCRIPTION
The number of the Chairman and Delegate units can be varied according to fit the
●
number of participants. (TS-800 Series: up to 64 units; TS-900 Series: up to 96 units)
Up to 16 Transmitter/Receiver units (when using TS-905 units only) and up to 12
●
TS-907 units (including instances where TS-905 and TS-907 are used in combination)
can be installed to create stable communication environment even in a large
conference room.
Designed for use in a high-ceilinged room, the TS-907 Transmitter/Receiver is capable
●
of communications in a room with ceiling height of more than 5 meters and less than 7
meters.
The Speaker Restriction function (1, 2, or 4) prevents confusion resulting from
●
simultaneous speeches by participants.
The speech system selection (first-in-first-out, last-in-first-out, or last-in-first-out after
●
2nd unit) enables the system to handle conferences in a wide range of situations.
The Chairman unit features a priority speech function. By talking while pressing the
●
priority speech key, the Chairman unit can override Delegate units.
Features
To prevent a howl, the monitor speaker of both Chairman and Delegation units is
●
turned off while the units are in use.
The Central unit can be used in combination with wired microphones or output source
●
equipment, depending on the purpose.
The 900 Series features a threefold vote function, which facilitates voting and counting
●
of "Yes," "No," and "Abstention" votes.
Both Chairman and Delegate units work either on the rechargeable lithium-ion battery
●
or AC current. With a fully charged battery, the unit operates for about 10 hours.
(assuming that the speech time amounts to one-third of the whole length of the
conference)
Dedicated microphones for Chairman and Delegate units are available in two types:
●
"standard" (primarily for use in a sitting position) and "long" (primarily for use in a
standing position).

Care should be taken to ensure the Chairman/Delegate Units are within the optimal
coverage area of the Infrared Transmitter/Receiver unit.
The Infrared Transmitter/Receiver unit must not be installed behind a user or any other
obstacle, as infrared signals will be unable to reach it. The Infrared Transmitter/Receiver units
must be installed to ensure that two or more units will always be in straight sightlines from
the Chairman/Delegate units.
If only one Infrared Transmitter/Receiver unit is used for communication, reception may be
interrupted if the infrared signals are blocked, either by an individual or obstacle. A minimum
of two Infrared Transmitter/Receiver units is required for an installation to enable the
Chairman/Delegate to always be able to communicate with them.

EQUIPMENT THAT AFFECT THE OPERATION
TS-800/900 SERIES
Equipment that affect the operation of the
Conference System units
Equipment that cannot be used in the same location as the System units.
• Plasma displays
Plasma displays emit a large amount of infrared radiation to illuminate the screen. For this reason, if
the Transmitter/Receiver unit is installed near a plasma display, or if terminals are used in front of the
plasma display, communication failure and noise may occur.
• Infrared LANs
• Infrared microphone systems
• Infrared simultaneous interpreting systems
As with the TOA Infrared Conference System, these systems also use infrared light. Thus, if used in
the same location, they could interfere with each other. In some cases, it may be the TOA system that
fails; in other cases, it may be the other system that becomes inoperable.
• etc.
Equipment that might cause unstable operation of the System units.
• Lighting equipment (spotlights and downlights)
When direct light from a spotlight or downlight reaches the infrared signal receiver of the
Transmitter/Receiver unit, communication failure or noise may occur.
Fluorescent lights have little effect on the Transmitter/Receiver unit’s performance. However, if light of
the incandescent lamp (downlight) is very intense, it could result in a slight decrease in the signal
traveling distance or a rise in noise floor. This problem can be avoided by increasing the number of
Transmitter/Receiver units installed.
• Sunlight
When direct sunlight hits the infrared signal receiver of the Transmitter/Receiver unit, communication
failure or noise may result. In general, this problem can be avoided by using (installing) the unit away
from windows or by covering windows with curtains or blinds.

CAUTIONS IN INSTALLING TS-800/900 SERIES
Cautions in installing the
Transmitter/Receiver unit
1. Install the Transmitter/Receiver unit away from windows.
Install the unit 2 – 3 meters away from the nearest
window, so that the effect of sunlight is minimized.
Sunlight
2 – 3 m
Note:
When effective coverage range is sought, installation will naturally be toward the center of the room.
Caution should be exercised when installing the unit close to the wall or near the corner of the room
to make it inconspicuous. If it is not possible to secure the above-mentioned distance, shading
sunlight with curtains or blinds will work.
2. IInstall the Transmitter/Receiver unit away from lighting equipment.
Lighting equipment may emit infrared portion of the light spectrum (especially incandescent lamps).
Installing the unit at least 50 cm away from lighting equipment minimizes the interference.
Ceiling
Fluorescent lights
50 cm or more
Note:
If the lighting equipment is mounted higher than (behind) the Transmitter/Receiver unit, there is no
need to worry (as in a case of the lighting equipment mounted flush with the ceiling).
If light does not directly hit the infrared signal receiver of the Transmitter/Receiver unit, there is no
need to worry. with curtains or blinds will work.
50 cm or more
3. Do not install the unit in pr oximity to the wall, column, and other obstacles.
Avoid installing the Transmitter/Receiver unit in close proximity to the wall, column or obstacles.
The unit could malfunction by detecting own infrared signals that are reflected.
Note:
A distance of 20-30 cm will be adequate to make the unit unaffected. However, caution should be
exercised when highly reflective materials such as a mirror are involved.
In particular, caution should be exercised when installing the unit in a large room with a column
in the center.
