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.

3Adjust the volume.
Adjust the volume of the receiver with the audio volume controls. After adjusting the volume
level at the infrared receiver and any connected external devices, the speaker can make
fine adjustments, such as level differences. (☞page 16, 17)
Turn off the power of the microphone and the infrared receiver after use.
Important:
• Do not assign more than one infrared wireless microphone to the same channel.
The noise may cause damage to the speaker, and an excessively loud volume may dam-
age your ears when the power switch of the microphone is turned on.
• While using the microphone, do not take the microphone close to the wireless powered
speaker (WX-LP100) (such as when adjusting the volume controls of the powered speak-
er).
Loud noises such as feedback may damage your hearing.
Note:
• Also read the operating instructions of the infrared receiver (WX-LR100, WX-LR100/A, WX-
LR100/B), the infrared receiver/amplifier (WX-LA20, WX-LA50), and the infrared wireless
powered speaker (WX-LP100).

Adjusting the volume
The microphone can control the volume of audio signals that are output from the infrared
receiver (WX-LR100, WX-LR100/A, WX-LR100/B), the infrared receiver/amplifier (WX-LA20, WX-
LA50), and the infrared wireless powered speaker (WX-LP100), and the volume of audio sig-
nals input to the line input terminal of the infrared receiver/amplifier (WX-LA50) and the infrared
wireless powered speaker (WX-LP100) (as of June 2009).
After adjusting the volume level at the infrared receiver and any connected external devices,
the speaker can make fine adjustments, such as level differences, by performing the following
operations on the microphone.
1Press the selector button
When the selector button is pressed for the first time after turning on the power, the [OWN]
selection indicator lights, and after that the selection indicator for the preceding selection
([OWN], [OTHER], [LINE]) will light. Then press the selector button repeatedly to select the
desired selection. The selection indicators light in the following order:
* The selection indicator lights for 5 seconds. If no operation takes place within this period,
the indicator turns off automatically.
2Press the volume button [D/C]
While the selection indicator for the selection made in 1 is lit, either press the volume button
or keep it pressed.
Pressing the volume button [D] will increase the volume, pressing [C] will decrease it. The
adjustment range is +6 dB to –16 dB, and every pressing corresponds to a change of
2 dB.
The selection indicator goes off 5 seconds after the volume button was pressed for the last
time.
• When [OWN] is lit
Adjust the audio volume of this microphone (input from the microphone opening, exter-
nal input and microphone input).
* Adjustment is not possible while muted ([OWN] selection indicator is blinking).

If you want to temporarily stop the audio transmitted from this microphone to the receiver for
one reason or another, without turning off the microphone, you can temporarily mute the audio
signals.
1Press the [PWR/MUTE] button.
When pressing the[PWR/MUTE] button once, the [OWN] selection indicator starts blinking
and the audio transmitted from the microphone to the receiver is muted. While muting is
activated, audio input of the [OWN] microphone (audio input from microphone opening,
external input and microphone input terminal) is muted. To cancel muting, press the
[PWR/MUTE] button again.
Note:
• After muting is maintained for approx. 5 minutes, the microphone is turned off automatical-
ly.
• In the muted state, volume control of the [OWN] microphone is disabled, but [OTHER] and
[LINE] are enabled.
• The muting operation may become disabled under certain circumstances. (☞page 12)

This function allows you to use an external microphone instead of the microphone opening of
this microphone. Connect an external microphone (for example, an electret condenser micro-
phone) to the microphone input terminal of the microphone, and transmit the audio to the
receiver.
1Turn off the power of the microphone.
2Using the ø3.5 mini-plug, connect the external microphone (for example, a commer-
cially available electret condenser microphone) to the microphone input terminal.
3Turn on the power of the microphone.
Important:
• Do not connect external devices (CD players or MD players) to the microphone input termi-
nal. Loud noises may damage your hearing. When an external device is mistakenly con-
nected, turn off the power of the microphone and the external device, disconnect the plug,
and connect the device to external input terminal.
Note:
• Once the ø3.5 mini-plug is plugged into the microphone input terminal, priority is given to
this audio transmission from an external microphone and the audio from the microphone
opening will not be transmitted.
• The microphone input terminal of the microphone is a monaural terminal. If a stereo exter-
nal microphone is plugged into the microphone input terminal, either the right or the left
channel audio will be transmitted.
• When fine-tuning the volume of external microphone using this microphone, select [OWN]
by pressing the selector button. For fine tuning, refer to "Adjusting the volume" (☞page 16,
17).
• Use a unidirectional microphone. The use of an omnidirectional microphone may cause
feedback.
• In addition to this manual, refer to the operating instructions of the external microphone to
be connected.
