Turning your hearing instrument on and off
Power-on delay
Your hearing instrument is equipped with a "power-on
delay" feature which can be activated by your
Hearing Care Professional. This allows you to turn the
hearing instrument on with an automatic delay of
6/12/18 seconds, so that you may insert the hearing
instrument into your ear without experiencing unpleasant
feedback (whistling).
