Before you start

Charge the recorder and have a compatible phone with the CozyLife companion app ready. Use the app identified in the device documentation. The setup video shows the demonstration interface in Chinese. Menu labels may differ with the app version or language.

The recorder saves audio on the device. File transfer creates a copy on your phone. Transcription and summaries are separate processing steps in CozyLife. For the first test, use a short, non-sensitive recording.

Watch the setup and recording demonstration

1. Add the recorder in CozyLife

  1. Hold the recorder’s power button to turn it on.
  2. Enable Bluetooth on your phone. Open CozyLife and start a nearby-device search.
  3. Choose the recorder card from the results and complete the prompts in the app.
  4. Open the device page and confirm it shows the recorder as connected.

If the phone asks for Bluetooth or nearby-device permission, allow it for CozyLife. Keep the recorder close to the phone during setup.

2. Save a short test recording

From the app, start a recording, watch the elapsed time, then tap Stop or End. On the recorder, double-press the recording button to start, press it once during recording to pause, and double-press again to finish. Check the device display and confirm the saved clip appears in the recorder’s file list.

Record a few clear sentences, end the session, then check the displayed duration. A recording that is still running or paused may not appear as a finished file.

3. Download and verify the audio

  1. Open the recorder’s file list in CozyLife and select the finished clip.
  2. Download it to the phone. For larger files, enable the recorder’s Wi-Fi transfer mode and join its hotspot when the app prompts you.
  3. Return to CozyLife and wait for the transfer to finish. Play the downloaded file and check that the duration and audio match the recording.
  4. When finished, turn off the recorder’s Wi-Fi transfer mode and reconnect the phone to its normal internet connection as needed.

The recorder hotspot is for file transfer. Your phone may show that the hotspot has no internet access. Keep that connection during transfer if the app requests it.

4. Create a transcript, summary or mind map

  1. Open the downloaded recording in CozyLife and choose the language spoken in the audio.
  2. Select the available processing options and submit the file.
  3. Open the transcript when processing finishes. Check names, figures and action items against the audio.
  4. Choose a summary format such as meeting minutes, class notes or interview summary. Review the mind map if the option appears.

To ask questions about a recording in AI Chat, finish generating its summary first. For live translation, open the translation feature, choose the source and target languages and start a separate session. Processing features and available languages depend on the app and service.

5. Fix common problems

The recorder does not appear in CozyLife

Confirm it is powered on and near the phone. Check CozyLife’s Bluetooth or nearby-device permission, then retry the search from inside the app. If it is already connected to another phone, disconnect that session before retrying.

The file is missing or Wi-Fi download stalls

End the recording first and refresh the device’s file list. For Wi-Fi transfer, confirm the phone joined the recorder’s hotspot and stayed connected. Return to CozyLife and retry with a short test clip. Verify local playback before removing the original recording.

The audio plays but transcription fails

Check that the downloaded file plays all the way through. Reconnect the phone to an internet connection, confirm the spoken language and retry a short clip. If the processing option is missing, check the current app version and service availability.
