3.7 Understanding the indicator light
When switching PilotOne II on,
the indicator light will illuminate
for two seconds indicating that
PilotOne II is ready to use.
The indicator light remains on as long as a button is
pressed.
If the indicator does not blink when a button is
pressed, PilotOne II needs to be programmed rst
by your hearing care professional.
The indicator light will be either
green or red depending on the
battery status.
Green: Battery ok
Red: <10 % left. Replace the battery
immediately
