It will only picks up loud enough decibels voice (any sounds).
So you could adjust the AVR level in record setting->AVR mode, select the best AVR level as you want,
and get the best effect of voice activated recording.
For L53 voice recorder, the AVR level could be selected from level 1 - 5; The lower number means
need higher decibels voice to activated the recorder, and it need louder voice; At level 5, it is very

10) Memory is full
When press REC, it doesn’t record, it shows “memory is full”, that means the voice recorder memory

computer directly
