This Help Guide is provided commonly for two models: ECM-W3 and ECM-W3S. For illustrations applied to the
descriptions common to both models, those of ECM-W3 are used.
Compatible cameras
This unit is compatible with a camera that has a Multi Interface Shoe such as a Sony Interchangeable Lens Digital
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 of this unit are factory-set to communicate with each other. Therefore, operations
usually needed for Bluetooth devices such as pairing and passkey entry are not necessary. With any Bluetooth device
other than the receiver and the microphone of this unit, on the other hand, communication is not possible.
For camera models compatible with this unit, view the following. (Another window will open.)

Slide switch (ANALOG/OFF/DIGITAL)
Select “ANALOG” (analog audio output), “OFF” (power off), or “DIGITAL” (digital audio output).
If your camera is compatible with the digital audio interface of the Multi Interface Shoe, set the switch to
“DIGITAL.”
Digital signal transmission from the receiver to the camera has the following merits over analog signal
transmission that is enabled by the switch being set to “ANALOG.”
Audio recording with less noises
Less audio delay during recording
Recording with 24-bit audio (only available in combination with the compatible camera)
Note

Movies recorded with 24-bit audio may not be played back normally on devices or software incompatible with 24-bit
audio, resulting in unexpectedly loud volumes or no sound.
If your camera is not compatible with the digital audio interface of the Multi Interface Shoe, set the switch to
“ANALOG.”
When the message “This accessory is not supported by the device and cannot be used.” is displayed on the
camera, set the switch to “ANALOG.”
If this does not help, see here.
When a TRS audio cable with the 3.5 mm diameter plug (commercially available) is connected, the receiver
outputs analog signals via the cable.
When a device with a USB audio input capability is connected, the receiver outputs digital signals.
When you do not intend to use the receiver, set the switch to “OFF” to conserve the battery power.
Mode switch (SEP/MIX) (ECM-W3)
By selecting a receiver mode with this switch before you start video recording with the camera, you can make
recordings with audio from either of the two microphones individually as the left or right channel audio; or recordings
with mixed audio from the two microphones.

Charging the built-in batteries
Each of the receiver, the microphone, and the charging case contains a built-in lithium-ion rechargeable battery. Connect
the charging case and a power source with a USB Type-C cable (commercially available) for battery charging.
Note
Before charging the built-in batteries, be sure to turn off the receiver and the microphone.
Battery charging can go on while the receiver and the microphone are turned on. However, placing the receiver and the
microphone in the charging case automatically turns them off. This means that the next time you use the receiver and the
microphone, you must select “OFF” once with the slide switch on the receiver and with the power switch on the microphone, and
then turn them back on.
In the event that the receiver and the microphone are removed from the charging case after battery charging is conducted while
the receiver and the microphone are turned on, placing them back in the charging case without changing the switch selection
does not start battery charging.
Place the receiver and the microphone in the charging case.
Note
Be sure to push in the microphone until it clicks into place. When the microphone is properly seated, its power lamp lights in
orange, indicating that the battery charging has started.

About the battery charging time
In the event of charging the built-in batteries while the receiver and the microphone are housed in the charging case, the
built-in batteries of the receiver, the microphone, and the charging case are simultaneously charged via the USB
connection.
About 10 minutes of battery charging enables about 30 minutes of use of the receiver and the microphone.
Time period required to fully charge the built-in batteries of the receiver and the microphone: about 2 hours*
Time period required to fully charge the built-in battery of the charging case: about 2 hours and 30 minutes*
Charging the built-in batteries of the receiver and the microphone while on the go
The charging case contains a rechargeable battery. By having it charged in advance, you can charge the batteries of the
receiver and the microphone when you have no access to a power source, for example, while you are on the go.
ECM-W3
The fully charged battery power of the charging case is sufficient for about 1 time charging for all the built-in batteries
of the receiver, the microphone No. 1, and the microphone No. 2 from the empty state to the fully charged state.
ECM-W3S
The fully charged battery power of the charging case is sufficient for about 2 times charging for the built-in batteries
of the receiver and the microphone from the empty state to the fully charged state.
Notes on charging the built-in batteries of the receiver and the microphone while on the go
In the event that the charging lamp on the charging case is blinking in orange when the receiver and the microphone are
removed from the charging case, the rechargeable battery of the charging case is running out of power. Charge the
battery of the charging case.
When the receiver and the microphone are properly housed in the charging case, close the lid of the case.
Connect the USB Type-C port on the back of the charging case and a power source with a USB Type-C
cable for battery charging.
The charging lamp ( ) on the charging case lights in orange, indicating that battery charging has started.
When the built-in battery of the charging case is fully charged, the charging lamp on the charging case goes out
regardless of the battery charging states of the receiver and the microphone housed in the charging case. When
the USB Type-C cable is disconnected at this point, battery charging for the receiver and the microphone continues
with the battery power of the charging case.

Time period required for charging the empty rechargeable batteries via the USB charging port (CDP - Charging Downstream Port) on the
computer to full capacity. It may vary depending on the using condition.
