Using the Variable Control Voice Actuator (VCVA)

When the microphone senses that sounds have reached a preset actuation volume level, the built-in Variable Control Voice Actuator (VCVA) starts recording automatically, and stops when the volume drops below the actuation level.

The VCVA feature helps extending recording time and conserves the memory by turning off recording during silent periods. This helps make the playback, with no lulls or dead space, more efficient and convenient.

When the sound volume is lower than the preset actuation sound level, recording automatically stops after 1 second approximately, and “STANDBY” flashes on the display. The record/play indicator lamp glows when recording starts and flashes when recording pauses.
