Before first use, fully charge the voice recorder. Connect the included Micro USB cable to the device's Micro USB port and the other end to a USB power adapter (not included) or a computer's USB port. The indicator light will show charging status and turn off or change color when fully charged.
2. Powering On/Off
To power on the device, slide the power switch to the 'ON' position. To power off, slide the switch to the 'OFF' position. The device will automatically save any active recording before shutting down.
Operating Instructions

2. Voice Activated Recording (VAD)
The device supports voice activated recording. When enabled, the recorder will only record when sound is detected, pausing during silence to conserve memory and battery.

Alternatively, connect the device to a computer or smartphone/tablet to play recordings.
4. Connecting to Mobile Devices (OTG Function)
The OTG function allows direct connection to compatible Android smartphones or tablets for instant data transfer and file management. Use an appropriate OTG adapter (not included) to connect the recorder to your mobile device. For iPhones, an additional converter may be required and must be purchased separately.
