Delayed activation
Please be aware that your hearing instrument may
take several seconds to boot up.
Your hearing care professional may have activated
a further delayed activation timer. This function delays
the activation of the hearing system for 9 or 15
seconds after the battery door is closed in order to
avoid any disturbance while placing it into your ear.
An acoustic signal confirms when your hearing
system is switched on.
