A screen for recording and playback
The 0.85-inch display shows recording and playback information on the device. The front control pad handles file navigation, while side buttons give quick access to recording functions. M21 also lists voice activation, timed recording and file segmentation in its parameter sheet.
Make a short recording before a meeting to check microphone distance, storage space and the selected mode. A visible screen is useful when the operator needs to confirm that a file has been saved.
Clip placement and battery planning
The rear clip can hold M21 on a notebook cover or clothing. Keep it stable and away from rubbing fabric; movement noise can be louder than the person speaking. The compact body is 55 × 26.5 × 21mm when the clip is included.
The listed 55-hour recording and 28-hour playback times are separate operating figures from the supplier sheet. Screen use, recording format and battery condition affect real use, so check a sample with the settings intended for the order.
Storage and recording settings
M21 is offered with 8GB, 16GB, 32GB or 64GB memory. The sheet lists PCM recording at up to 1536Kbit/s; higher data rates use storage faster. For long sessions, allow room for the full audio file and keep a charged unit available rather than judging capacity from battery runtime alone.
Voice activation, segmented files and scheduled recording can be selected to fit the session. Ask for the exact menu and file-format configuration on the approved sample before writing instructions for retail buyers.
