Configure and verify a short field recording
8 steps
Inspect power and storage
Set the switch to USB/OFF, fit the batteries in their marked orientation and insert a supported microSD card. Back up card contents before any reformatting.
Check: Battery contacts and storage are correctly fitted.

Connect in USB/OFF mode
Connect the data cable with the switch still in USB/OFF. Open the official Configuration App and identify the connected recorder.
Check: The application reads the intended device.
Set the clock
Use the application to set the recorder time from the computer. Check the computer clock and record the time basis, including UTC handling.
Check: The device has a valid current time rather than an unset epoch value.
Choose a conservative test configuration
Select an audio sample rate and gain appropriate to the sounds of interest. Configure a short recording period and review the app storage and energy estimates.
Check: The chosen settings fit the card and battery plan; estimates are not treated as guarantees.
Apply and disconnect
Apply the configuration, confirm it was accepted, and disconnect USB. Keep the device in a quiet, known test location.
Check: The configuration is stored and the recorder is ready for a standalone test.
Record a short sample
For an immediate continuous test use DEFAULT. For testing the saved schedule use CUSTOM with the clock and any required acoustic-chime condition satisfied.
Check: The switch mode matches whether an immediate recording or a schedule is being tested.
Stop and inspect the WAV
Return to USB/OFF before removing the card. Open the resulting WAV on the computer and check duration, timestamp, audibility and clipping.
Check: A readable, correctly timed file contains the expected sound.
Document the deployment baseline
Record firmware, sample rate, gain, time setting and test result. Fit the appropriate protective enclosure and check its acoustic opening before later field placement.
Check: A tested configuration and deployment record exist.
