iii. Resetting ELSA timer
ELSA continuously assesses the volume levels you listen at, the
moment you switch on the headphones. To reset ELSA timer and data,
restart the headphones by powering it OFF and then switching it ON.
Listening volume level is NEVER constant. All audio content have
louder and softer parts.
User will be exposed to ALL volume level ranges. Please expect time
taken for ELSA to adjust volume to vary during each session.
