4. Operating Instructions
4.1. Recording
To begin recording, ensure the device is powered on. The recording process starts automatically when sound is detected if Voice Activated Recording (VAR) is enabled. If VAR is off, recording begins immediately upon power on. The built-in professional noise reduction chip enhances audio clarity during recording.
4.2. Voice Activated Recording (VAR)
When Voice Activated Recording (VAR) is active, the device will automatically start recording when sound is present and pause when there is no sound. This feature helps conserve battery life and memory space by only recording relevant audio.
4.3. Playback
Connect the provided earphones to the watch's 3.5mm audio jack for private listening. The watch supports MP3, WMA, and WAV audio formats for playback. Use the '+' and '-' buttons on the side of the watch to adjust the volume during playback.
4.4. Timestamp Function
Each recording is automatically marked with an accurate generation time and end time. This feature is useful for organizing and referencing recorded audio files.
4.5. Fast Forward and Fast Backward
During audio playback, use the '+' button to fast forward through the track and the '-' button to fast backward. These buttons also control the volume level.

This diagram illustrates the location and function of the control buttons on the side of the watch. The '+' button serves for fast forward and volume up, while the '-' button is for fast backward and volume down.
5. Maintenance
5.1. Cleaning
Wipe the surface of the recorder watch with a soft, dry cloth. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the device.
5.2. Storage
When not in use for extended periods, store the device in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Ensure the device is powered off before storage.
6. Troubleshooting
- Device not turning on: Ensure the battery is sufficiently charged. Connect the device to a power source using the USB cable and attempt to power it on again.
- Cannot record: Verify that the device has sufficient internal memory. If memory is full, connect to a computer and delete unnecessary files. Confirm the power switch is in the 'ON' position.
- Poor audio quality: Ensure the microphone is not obstructed. Record in a quieter environment to minimize background noise. While the device features noise reduction, extreme noise levels may still affect recording clarity.
- Cannot connect to computer: Try using a different USB port on your computer or a different USB cable. Ensure the watch is powered on when attempting to connect to the computer.
- No sound during playback: Check that the earphones are securely connected to the 3.5mm jack. Ensure the volume is not set to its minimum level. Verify that the audio files are not corrupted.
