Features
CONTENTS
This unit is a receiver which integrates both a sensor receiving infrared light from the infrared wireless microphone (MTD-09,
MHH-09) and a receiving component. Integration of a receiving component and a sensor allows an infrared wireless micro-
phone system to be simply constructed by mounting this unit on the ceiling. Use of the supplied conversion box provides
extension between the receiver and an amplifier, and accordingly leads to flexibility in installation locations.
This unit also includes the feedback blocker to decrease feedback generated when the microphone and speaker approach
each other.
• As the unit uses infrared light, it is not affected by interference from adjacent rooms.
• The microphone is available as a handheld model (MHH-09) and as a pendant “teardrop” model (MTD-09). The
2-channel microphone of this unit and the audio level of the line can be controlled with the pendant type.

Caution about interception of transmission
This product is a wireless system using infrared, and the transmission and reception of audio signals are possible within
the range that the infrared light can reach.
If any third party is within the range of the infrared, the audio signals can reach anywhere unless there are obstacles (such
as walls). Therefore, if there is no action taken to prevent interception, malicious third parties may listen to content by inter-
cepting the infrared intentionally.
In order to handle this problem, you may set up infrared shielding materials such as shade curtains to close the transmit-
ting and receiving range to reduce the interception.
We would like you to fully understand the risks of using this product without taking precautions for interception, and we
recommend you take your own preventative measures.
If interception occurs due to negligence or the specifications of the infrared wireless, we shall not take any responsibility for
the damages that are caused thereby.
Caution about external-device control function
This product is not intended for a security application.
Never use the external-device control function of the product for security use.
We shall not take any responsibility for damages resulting from troubles or malfunction due to cable disconnection.
Caution about feedback blocker
The feedback blocker, with which this product is equipped, is not intended to suppress the feedback howling completely.
A sudden large noise may be produced even when the feedback blocker is activated.
When installing speakers and a sensor, make sure that the feedback howling is not produced.

The installation should be carried out following local standards for electric products.
Warning
• Be sure to contact your dealer for installation.
Before installing, turn off the power of the connecting product. In addition, be sure to read "Precautions" carefully and
follow the instructions. Moreover, be sure to read operating instructions of the connecting product as well.
•Power
Connect the power plug of the AC adaptor by using a circuit breaker in any of the following ways:
Install this product near the power outlet.
Connect this product with the breaker of a distribution board which has a contact point of not less than 3.0 mm
{3/32 inches}.
Use a breaker that can block all the poles except for protective earth conductors.
Connect this product via the outlets of devices that can block power such as a power control unit.
•Static Electricity
Discharge any static electricity charged in your body by touching a metallic area before installing in order to prevent
damage caused by static electricity.
•Install the infrared sensor within a range that the microphone can reach and in a location that can be
seen in moving range.
•Be sure the connector and coaxial cable are connected in the correct way.
If the process and connection are incomplete, receiving sensitivity may be reduced and product will be more easily
affected by external noises.
•Do not install in locations where strong light or sunlight strikes the infrared sensor directly.
If the product is installed near a window, the product is subject to the solar light even if the solar light does not strike
it directly, which may reduce the receiving sensitivity and shorten the range. Install the product as far from strong light
as possible (more than 5 m {16 feet}). If the situation is still not improved, it may be better to install it farther from
window side or use a curtain or window shade.
•Avoid installing near a warm air flow path. In addition, if the product is installed in locations with an
abundance of moisture, dust or vibration, there is a risk of damage.
•In locations with a large amount of dust, the dust may accumulate on the Infrared Sensor Cover, which
may interfere with reception of the infrared signal. As a result, the range may be reduced. Therefore,
avoid installing in locations with a lot of dust.
•Do not install and use in following locations:
①Locations directly affected by rain or water (including spaces under the eaves).
②Locations such as a pool where medical agents are used.
③Locations such as a kitchen or factory workshop where there is a lot of vapor or oil and special environments such
as in flammable atmospheres.
④Locations where radiation or X-rays and strong electric fields or magnetism arise.
⑤At sea or along the coast, and locations such as hot springs where corrosive gases arise.
⑥Locations with a lot of vibrations caused by large vehicles or ships (this is not a product for vehicles).
⑦Locations where water drops made by condensation will splash.
Precautions for installation

12
•Plasma television screens generate infrared interference. It is not recommended to use a plasma
display in the same room where the TLD100 is installed.
However, if a plasma screen must be used, install it in the following way and after confirming
operation, use it very carefully.
①Install the infrared sensor in a location where side and back of plasma display cannot be seen, and install it as far
away as possible (more than 10 m {33 feet}).
②The distance between the infrared sensor and microphone should be as short as possible (within 3 m {10 feet})
while in use.
③
④
Do not put any blocks (including the human body) between the infrared sensor and microphone while in use.
Even after following these recommendations, interference may still occur.
•The distance between a fluorescent lamp and the infrared sensor should be as far apart as possible
(more than 1 m {3.3 feet}) in installing.
•If a remote controller such as an audio-visual device or air conditioner is controlled by an infrared
sensor, noise or sound breaks may occur.
•If there are any other devices making strong noises, product may sometimes be impossible to use.
In that case, install the product farther away until it can be used.
•Ceiling height is expected to be 2 m {7 feet} to 4 m {13 feet}. If it is out of this range, the arrival range
may be shortened.
•The base color of wall, floor, and ceiling should be white or light colors. With black or dark color
surfaces, the arrival range may be shortened.
•A reflection from the wall is used in the arrival range. If the wall is far away from the area of use, the
arrival range may be shortened.
•Sound breaks may occur near windows or in rooms with a lot of windows. In this case, it may be
useful to use light-colored curtains or window shades.
•If a microphone is used near and facing a wall, sound breaks may occur.
•For tightening bolts and screws, pay attention to the following points:
①Torque control is necessary for tightening the bolts and screws.
②Torque wrench and torque driver are necessary for controlling the torque.
③Never use any impact driver or electric drill because torque control is difficult even if they have a clutch. Their use
may result in damage to the mounting part.
•After mounting, confirm visually that the product is firmly and stably fixed. If the product is properly
installed, it will not wobble or make noise.
•In installing this infrared sensor, be aware of the following:
①Be sure that the installation is carried out by qualified personnel when installing at high locations.
②Before installation, confirm that there is nobody around.
③In order to carry out the installation safely and surely, pay close attention to the safety control.
•The supplied safety strap shall be used.
Be sure to firmly secure the safety strap to the ceiling mount bracket at installation.
•Precaution for installation place and securing of the conversion box:
The conversion box shall be installed on a stable place such as on a shelf and secured with screws as necessary.
•Do not apply strong force to this unit. Failure to observe this may damage this unit.

Note:
• Settings of the DIP switch No. 1 - 6 are recognized when the power of this unit is turned on. Therefore, change of set-
tings after turning on the power does not update the settings of this unit. When settings of the DIP switch are
changed, the power needs to be turned off and on again.
The functions settable with the DIP switch can also be changed through RS-232C (page 29).
In this case, the communication control can change settings even after the power is turned on.
• The internal circuit is physically changed by the DIP switches No. 7 and 8. It is impossible to change the circuit
through RS-232C. Be sure to set these switches manually to ON or OFF.
• Improper setting for the DIP switch No. 8 may shorten the transmission range.
* Default setting
In this illustration, the side with
each switch number is OFF.
