Via 3.5mm TRRS audio cable
The receiver can also be connected to a smartphone to provide audio signal input for the
smartphone.
1. Turn off the receiver.
2.
Insert the straight plug of the 3.5mm TRRS audio cable into the earphone jack of the
smartphone.
Insert the 90°plug of the 3.5mm TRRS audio cable into the “LINE OUT” jack of the receiver.

please connect correctly.
When recording videos, not all Android devices support external microphones. You may need to
download a third-party APP and set the sound source to external microphone.
If you are using a tablet, Mac or laptop with an earphone/microphone jack, connect the device
to the receiver through the 3.5mm TRRS audio cable in the same way.
Attaching the microphone to clothing
Attach the transmitter to your clothing.
1. Attach the transmitter to your desired location on the clothing, such as the collar, a breast
pocket, etc., with the clip.
Be sure to attach it to the location best-suited for the recording or sound conditions.
Precautions for Use
Before attaching the transmitter to your clothing, charge the transmitter's built-in battery
sufficiently enough.
If you use a medical electrical device such as a pacemaker, do not attach the transmitter to your
clothes, such as the breast pocket or inner pocket. Using the microphone near a medical device
may adversely affect it.
Pairing the transmitter and receiver
The transmitter(s) and receiver are factory-set to communicate with each other. Therefore, pairing
operation is not necessary, they can be used directly.
If the communication is disconnected or two transmitters are required to communicate with one
receiver simultaneously, please follow the steps below.
1. Turn on the transmitter and receiver.
2. Press and hold the volume buttons “+” and “-” on the receiver for 2 seconds simultaneously,
the receiver enters into the pairing state and the state lamp
blinks in blue quickly (twice
per second).
The receiver will automatically exit the pairing state in 10 seconds.
3. While the state lamp on the receiver is blinking quickly, press and hold the “Pair” button on
the transmitter for 2 seconds, the transmitter enters into the pairing state and pairs with the
receiver.
When the transmitter is in the pairing state, its state lamp blinks in blue quickly (twice per
second).
4. When the pairing is complete, the state lamp
on the receiver stays lit in blue, and the
state lamp
on the transmitter blinks in blue slowly (once per 2 seconds); it indicates
that the pairing is successful and the communication connection between the transmitter and
the receiver has been established.
Precautions for Use
If pairing fails, the state lamp blinks once per second. If this happens, redo the procedure from
the beginning.
One receiver can only communicate with one or two transmitters simultaneously.
Attaching the fur wind screen
Attach the fur wind screen to the transmitter to reduce pop noise caused by breath or strong wind.
1. Place the notched side of the fur wind screen chassis towards the back of the transmitter, and
then attach it down to the top of the transmitter.
2. After attaching, you will hear a click. At this time, the two protrusions on the inner wall of the
chassis of the fur wind screen fit into the jacks on both sides of the transmitter.
Precautions for Use
When attaching or removing the fur wind screen, be sure to hold its chassis.
If the fur wind screen is wet, remove it from the transmitter and let it dry in the shade.
Recording
Recording with the Transmitter (TX)
Use the receiver connected to a camera (or a smartphone) and the transmitter attached to the
subject's clothing for recording sound.
1. Turn on the power of the transmitter, receiver and the connected device.
After both the transmitter and receiver are turned on, the state lamp
on the receiver stays lit
in blue, indicating that a communication connection has been established between the devices and
clear audio recording is available.
If no connection is established – the state lamp on the receiver blinks once per second, bring the
transmitter and the receiver closer to each other for another attempt. The devices may be under
influence of environmental or other factors.
2. Ensure that the state lamp on the receiver is lit, and press the record start button on the camera
(or smartphone).

If the transmitter is placed in close proximity to the camera (or smartphone), noise may also be
recorded due to RF interference. Keep the transmitter at least 1m (3 ft.) from the camera (or
smartphone) during use.
If there is noise or there is no sound because of deteriorating communication, the state lamp
on the receiver blinks once per second. Ensure that the distance between the devices is
not too far, and no obstacles are between them. Continue use when the state lamp
on the
receiver is constantly lit in blue.
When the recording is finished or you do not intend to use WM2, turn off the transmitter and
receiver to conserve the battery power.
Recording with an external microphone
Connect the supplied lavalier microphone to the transmitter for recording.
1. Make sure that the transmitter is turned off, and then connect the lavalier microphone to the
external microphone input jack on the transmitter.
The internal microphone of transmitter automatically turns off and the sound picked up by the
external microphone is recorded.
2. Attach the transmitter to a proper location, such as a belt, with the clip.
3. Clip the lavalier microphone to your desired location on the clothing, such as the collar, a breast
pocket, etc.
External
microphone
Precautions for Use
When the fur wind screen is attached to the transmitter, remove it from the transmitter.
Use an external microphone compatible with the plug-in power. The external microphone is
powered by the transmitter.
Do not touch the external microphone while recording, as this will cause the noise generated
when touching to be recorded.
If the external microphone is placed near speakers/headphones, a high pitched noise may be
heard (howling effect). This is caused by the external microphone catching sound from the
speakers/headphones repeatedly. In this case, place the microphone as far as possible from
the speakers/headphones.
If you are using other types of audio input, such as an electric guitar, connect the device to the
“LINE IN” jack on the transmitter with a matching cable (not supplied).
