Mine has been set to off since day one. Double checked before I record too.
Except all recordings I did at an event, for whatever reasons, my dr-05x has haphazardly combined randomly the recordings in a weird and senseless approach I can't even piece them together.
A recording I did, say an hour ago, 5 seconds of it is mixed with a recording from 30 minutes ago, and vice versa.
Seemingly no pattern, just confused recordings.
My head is even aching from all the audios I've lost from this abnormal behavior. Many interviews I did, verified it is recording and yet, now I just can't even play them as only 5 seconds of them are recorded, and spread across multiple saved files.
What a clown device!
