Your hearing instrument is
"on" any time a functioning
battery is properly placed in
the compartment and the
battery door is closed.
Some hearing instruments
are programmed to have a
power on delay. Your hearing professional will
check the box below if your hearing instruments
have this feature.
Your hearing instruments have a power
on delay.
The power on delay means that your hearing
instruments will take several seconds to turn on once
the battery door has been closed. This feature allows
you to get the hearing instruments in your ear before
they start to amplify sound.
