For pairing methods and precautions when using with a Windows PC, please refer to the User Guide (https://go.amivoice.com/l/83072/2022-11-29/dxvk4x/83072/1669707349nzHUe5m1/WT01_usersguide.pdf)please look at.
Generally in a Windows environment, after connecting to Bluetooth, the Bluetooth settings screen will be displayed after pairing in order to use it as Bluetooth audio or a headset, so you will need to "connect" before using it.
When pairing, if headset (HFP) and communications (SPP) profiles are displayed, we recommend pairing with HFP only if you are not using SPP.
After that, you can use them by setting "Bluetooth Audio" as the "Default device" for the playback device and "Bluetooth Audio" as the "Default device" from the Sound Control Panel.
The names and settings of each settings screen will vary depending on the Windows OS version, type of Bluetooth device, etc.
We do not provide support for inquiries about connection methods using a Bluetooth adapter built into your PC or a commercially available USB-connected Bluetooth adapter. Please contact the respective manufacturer.

・Mode: 1 (GATT/SPP)
・Microphone sensitivity: 10
・Speaker volume: 9
AGC: ON
AGC (Auto Gain Control) is a function that adjusts the speaker volume as needed.
If you want to produce a louder volume from your speakers, we recommend setting it to OFF (when playing an audio file that is quieter than -12dBFS, the volume will be louder with the AGC setting set to ON than with the AGC setting set to OFF).
When using in IP calls, we recommend setting this to ON to prevent noise from getting into the microphone.
・SPNS: ON
SPNS (Send Path Noise Suppression) is a microphone noise suppression process.
ON enables it, OFF disables it. If you connect an external microphone with noise suppression processing to "AmiVoice Front WT01", we recommend turning it OFF to prevent noise suppression from working twice.

The device name is "WT01-xxxxxx" displayed on the back of the unit.
"xxxxxx" is a six-digit alphanumeric code.

The old version had a physical switch that allowed you to adjust the microphone sensitivity, but since the new version is digital, this is no longer used.
It's a remnant of an older version.

Equipped with two microphones, it processes the input sound and obtains spatial information about the sound that cannot be obtained with a single microphone, allowing it to control directionality and estimate the direction from which the sound is coming.

If there are three metal parts on the end of the plug on the earphone side, it is a three-pole connector, and if there are four, it is a four-pole connector.
There are two 4-pole standards: OMTP and CTIA. Starting from the top of the connector, they are as follows:
[OMTP] 1. Left 2. Right 3. Mic 4. Ground
[CTIA] 1. Left 2. Right 3. Ground 4. Mic

It is not waterproof, but splash-proof.
It can be used outdoors in light rain, but do not pour water directly on it or immerse it in water.

This is one of the Bluetooth standards.
[GATT (Generic ATTribute)]
This is a communication standard that uses Bluetooth Low Energy (BLE), which has a medium communication speed and emphasizes power saving, allowing it to operate for several years on a single button battery.
[SPP (Serial Port Profile)]
This is a communications standard that uses Bluetooth like a serial port to send and receive low-level data.

The battery voltage of the "AmiVoice Front WT01" starts at 3.7V, and when it falls below 3.2V it goes into "Battery Low", and when it reaches 3.1V it goes into "Power Off".
Looking at the discharge characteristics of a lithium-ion battery, the voltage drops rapidly at the end, so expressed as a percentage, it is estimated that there is about 2% remaining when the "Battery Low" state is reached.
Once the battery reaches low, the device will power off after about 5 to 10 minutes if in use, or after a few hours if in standby.
