Main Features
This is the first microphone created with 2.4G Digital Wireless Technology, avoiding interferences issues
stipulated in wireless microphone that you can enjoy high-quality sounds now.
First innovative 2.4G Digital Wireless Technology in Industry is featured with its high-speed
transmission and 60m linear reception; it used for no-harassment in management of channels with audio
quality in perfection rendered!
2.4G Technology is featured on its extremes of energy saving; it use of alkaline battery (1.5V AA x2) that
is endurable more than 30 hours successively.
The exterior streamlined design, in line with visible pearl black paint and further thermal UV treatment, is
free of paint falling everlastingly which highlights its high quality.
The dustproof cover, made of high-stiffness of steel, presents higher level of protective effects from
extremely precise electroplating treatment and coating on the surface; the closely integrated design in the
microphone and dustproof cover is excellent in drop and shock resistance which significantly reduces extra
sound generated from shakes.
Volume Adjuster is uniquely attached that + - buttons on the microphone enables to adjust volume
remotely with ease.
The ultra-thin design of mini receiver at 200g enables you to hand carry in convenience or include it into
decoration at home simply or use with a power bank outdoors.
The set is equipped with thick, solid bass and clear pitches that highly sensitive microphone component
enables presentation of genuine human voice which is applicable to multiple purposes such as singing,
giving speech, conference and teaching.
Within echo sounds effects perfectly sing in Karaoke.
Need not to connect an audio mixer, background music and microphone sound mix down automatically.

II. Battery Installation
1. As shown on above chart：
Rotate bottom side of microphone counterclockwise until the sleeve is removed.
2. Please put into 2 batteries (1.5V AA Alkaline Battery) correctly into the battery compartment that negative
pole is toward the microphone head.
3. Rotate the bottom side of microphone back clockwise once Item 2 is done.
4. The batteries shall be removed if not use microphone for a long time, avoiding damages of springs and
circuit inside arisen out of battery fluid flowed.
5. Match Key(above the battery)：It is used for match between microphone and receiver (It is default paired
already).
III. Operation
Frequency of receiver and microphone has been matched while in delivery, please operate as follows:
1. Power on the microphone by Power Switch. At this time, the green light is on. At the mean time, volume
light of receiver is on, referring to volume of microphone.
(Note：If the pairing light is off, means receiver and microphone is not match which needs to be
done anew.)
2. Please operate as follows for matching microphone anew if necessary：
a. Power on the receiver and microphone; remove bottom sleeve of microphone.
b. Press match key of microphone and power light is flashing, then press match keys of receiver (MIC1 or
MIC2) that the receiver is entering into status of searching frequency now. When the pairing light of
receiver is on, means they are matched.
c. Under normal situation, the above matching should be done within 15 seconds. If not, the flashing will turn
off automatically.
