Do not assign more than one transmitter
to the same channel.
The noise generated when the power switch
of the product is turned on may cause dam-
age to the speaker, and an excessively loud
volume that may damage listeners’ ears.
Do not swing the product around on its
strap.
The strap might come off, resulting in person-
al injury or damage to the product.
Insert the battery with correct polarity
(+, –).
If reversed, the battery may explode or bat-
tery fluid leak out, resulting in fire, injury or
soiling.
Do not use NiCd batteries.
These could cause internal damage, result-
ing in a fire.
[Precautions for use]
• Operating temperature:
5 °C - 35 °C {41 °F - 95 °F}
When calculating the battery life, note
that temperatures below 10 °C {50 °F}
shorten the battery duration.
• Do not disassemble the product or touch
internal parts.
• Battery power is slightly consumed even
when the power of this product is OFF. If
the battery is left unused, that may result
in liquid leakage. To prevent this, remove
the battery from the product when
unused for a long time.
• Exercise care when using the product in
high places.
If it falls down, it may cause personal
injury or suffer damage.
• Do not use or leave the battery in places
where it will be exposed to high tempera-
tures, such as in strong direct sunlight, in
a sun-heated car, by the fire, or in front of
a stove.
• Do not touch the battery poles or con-
tacts inside the battery cover with dirty
hands. Otherwise poor contact or noise
may result. If dirty, wipe off with a dry soft
cloth.
The contacts inside the battery cover
tend to get dirty. Clean them regularly
(about once a month) with ethyl alcohol.
Do not use solvents, such as benzine or
thinner, or a metal polish. Otherwise the
contacts may become deformed or dis-
colored, or the brass plating may come
off.
• Do not use a deteriorated or short-circuit-
ed battery. A battery in this condition
may leak fluid, overheat and cause dam-
age.
• The product is not made to drip-proof
specification.
Do not use the product with the wet
hands in a place where it is directly
exposed to water.
• Do not cover the infrared emitter with
hands, clothes, or labels, etc. Otherwise
the sound will be blocked or interrupted.
• Do not swing the product around on the
neck strap. To prevent strangling, the
closure of the strap provided for hanging
the product around the neck is designed
to give way under pressure. If swung
around on the neck strap, the closure will
open and the product will fly away,
resulting in personal injury or damage to
the product.
• Maintain a distance of 50 cm {19-11/16"}
between infrared wireless microphones
and a distance of 2 m {7'} or more
between the infrared wireless micro-
phone and the infrared sensor.
Radio frequencies may cause interfer-
ence.
• The product is designed for indoor use.
• Use the product in a location where it is
relatively shielded from noise produced
by rotating machinery, transformers or
the ignition system or automobiles.
• Do not place the product on top of heat-
generating equipment, such as powered
amplifiers, video monitors or measuring
instruments, and do not leave it in a
closed car in hot summer. When storing
the product, do so in a dry place.

• Walls or people located between the
infrared wireless microphone and the
infrared sensor will block infrared radia-
tion, so that no sound will be heard.
• The product is high-precision adjusted;
exposing it to strong impact or dropping
it on the floor may change its characteris-
tics. Handle the product with due care.
Do not expose the product to shock or
impact as this will cause the audio output
of the infrared receiver to give off noise
on impact.
Product care
• Clean the power source with a dry cloth.
• Do not clean with volatile liquids such as
benzine and thinner.
• When using a chemical cloth for clean-
ing, observe the cautions provided with
that product.
Useful hints
• Noise prevention
Turn off the power of this product, and
turn down the volume of a powered
amplifier, mixer, etc. before replacing,
removing or inserting the battery, as this
might produce a large noise from these
devices.
• For a clear sound without noise content,
use the product at a distance of up to
8 m {26'} from the infrared sensor. When
you get a lot of noise, use the product as
close as possible to the infrared sensor,
within a range of 2 m to 8 m {7' - 26'}.
Using the product within a distance of
2 m {7'} from the infrared sensor may
cause crossover to unused channels and
interference.
• Volume control
When the volume control from this prod-
uct goes wrong, move closer to the
infrared sensor or change positions and
then try again to adjust the volume.

Preface
The product is a pendant type PLL infrared wireless microphone.
It can be used in combination with the following infrared products (hereinafter, receiver). (as of
June 2009)
U.S. and Canadian fields: Infrared Receiver (WX-LR100), Infrared Receiver/Amplifier (WX-
LA20, WX-LA50), Infrared Wireless Powered Speaker (WX-LP100)
European and Asian fields: Infrared Receiver (WX-LR100/A, WX-LR100/B), Infrared Receiver/
Amplifier (WX-LA20, WX-LA50), Infrared Wireless Powered Speaker (WX-LP100)
• The use of a PLL synthesized system allows selecting one out of four available frequencies
(1 of 4 channels).
• The transmitting channel is changed by operating a channel selector.
• The product can derive its power supply from a rechargeable battery (AA size), a dry cell
(AA/LR6 size) or a charger (option). (☞page 30)
• Connection of the charger (WX-LZ150) to this product allows our nickel metal hydride bat-
tery to be charged.
• Connecting an external microphone or any other external sound source to the product’s
microphone input terminal or external input terminal will allow you to transmit audio to the
receiver.
• The audio level (volume) output to the receiver can be adjusted on the microphone.
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 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 intercepting the infrared
intentionally.
In order to handle this problem, you may set up infrared shielding materials such as shade cur-
tains to close the transmitting 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.
