Start recording and check the controls
M2 starts recording with one action on the body. The supplier sheet lists a wired multifunction control for playback and deletion, along with an LED playback indicator. Check the exact supplied control cable and button sequence on the approved sample before writing instructions for your market.
A short trial recording confirms the microphone position, operating mode and file save before a long meeting or interview.

Plan battery and memory separately
The 380mAh battery is listed for up to 60 hours of continuous recording. The 8GB configuration is listed to hold up to 90 hours of audio at the stated recording setting. The battery may finish before the memory fills, so plan both limits for the intended session.
M2 also lists optional voice activation, automatic file splitting and 60-day standby. Voice activation depends on the sound level and the position of the recorder; test it near the intended speaker.

Place the 4.5mm body on a suitable surface
The magnetic housing can hold on a suitable steel surface. Check the strength on the actual panel before leaving the recorder unattended. Keep the microphone opening away from fabric, paper and vibrating metal; each can affect the recorded sound.
The brushed aluminum body measures 69 × 41 × 4.5mm. Compare that size with the space available in the planned installation or carry position.

Choose storage and review the sample
The supplier quotation lists 8GB, 16GB, 32GB and 64GB versions. The four USD quantity prices on this page use the 8GB cost. Ask for the selected memory version on the sample, then confirm the file format, transfer method, charging cable, wired control and package contents before a bulk order.
The source sheet lists MP3, WMA and WAV playback. If a particular file format is required by your customers, record a test file and play it on their intended computer or phone.
