Compatible cameras
The Wireless Microphone ECM-W2BT (referred to below as “this unit”) is compatible with a camera
that has a Multi Interface Shoe such as a Sony Interchangeable Lens Digital Camera (referred to
below as “camera”).
- Even if your camera has a Multi Interface Shoe, you may be unable to use it with this unit or some
functions may not work.
- The receiver and the microphone are factory-set to communicate with each other. Therefore,
operations usually needed for Bluetooth devices such as pairing and passkey input are not
necessary. Communication is not possible with a receiver and microphone not sold as a pair,
multiple microphones, or any other Bluetooth device such as a smartphone, computer, etc.
For camera models compatible with this unit, view here. (Another window will open.)

Charging the receiver
Connect the receiver to a computer to charge the receiver's built-in battery.
Note
While charging the battery, keep the receiver turned off. Turning on the receiver while charging makes the receiver ready for
power supply and stops charging.
Do not apply force to the receiver when you connect the receiver to a computer. This may cause damage to the receiver or the
computer.
When you connect the receiver to a notebook computer that is not connected to an AC power source, the battery of the notebook
computer may be depleted rapidly. Do not leave the receiver connected to the computer for a long time.
Charging the battery or the connection with customized or hand-built computers is not guaranteed. Depending on the type of
USB device used, charging may not function properly.
Operation with all computers is not assured.

Recording
Use the receiver attached to a camera and the microphone attached to the subject's clothing for recording sound.
Note
Depending on your camera, the “DIGITAL” audio output may not be supported. For the camera models that support the
“DIGITAL” audio output, visit our website at:
https://www.sony.net/dics/w2bt/
Turn on the power of the camera and set it in standby mode.
1
Turn on the receiver and the microphone.
Select your desired audio output with the slide switch (MIC OUT ANALOG/Power OFF/DIGITAL) on the receiver.
Select “ON” with the power switch on the microphone.
Immediately after both the receiver and the microphone are turned on, the LINK lamps on both devices start
blinking slowly in blue. This indicates that each of the devices is making a series of attempts to detect, connect to,
and authenticate the other device. When a communication connection is established between the devices and clear
audio recording is available, the LINK lamps on both devices stop blinking and stay lit in blue.
If no connection is established, bring the microphone 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 LINK lamp on the receiver is lit, and press the record start button on the camera.

When the audio output that is not supported by your camera is selected by the slide switch on the receiver, a cautionary message
may appear on the camera's finder screen. In such a case, select the supported audio output.
While recording is in progress, changing the receiver mode with the mode switch may cause a failure in switching the receiver
mode, a failure in audio recording due to disconnected communication, or noise in a recording. Before selecting a receiver mode
with the mode switch, be sure to stop the recording.
While recording is in progress, changing the audio recording volume with the ATT switch may cause operation sounds of the
switch to be recorded. Before selecting an audio recording volume with the ATT switch, be sure to stop the recording.
To avoid the possibility of the confirmation beep (Audio signals) at the start of a recording being picked up by this unit, it is
recommended that you set [Audio signals] to [Off] on your camera. For further details, refer to the operating instructions of your
camera.
When using this unit in the MIX mode, if the receiver and microphone pick up the same sound, it causes an echo or clipping
noise. Place the microphone farther away from the receiver not to pick up the same sound.
When using this unit in the MIX mode, if the power of the microphone turns off or the receiver and microphone are not connected
when you start recording, noise or no sound may be recorded. Ensure that the LINK lamps of the receiver and microphone are lit
in blue and connection is established, and then start recording.
The receiver receives power supply from the camera as well. Depending on your camera, however, it may not be capable of
supplying power. For the camera models that support power supply to the receiver, visit our website at:
