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.
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.
• 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.
