Step 6: Switching off your sona:vogue intro
You can turn off your sona:vogue intro by opening the
battery door.
Step 7: Replacing the battery
If the battery needs to be replaced, sona:vogue intro
will play an acoustic signal (two beeps, each 1 second
long). This signal is repeated until the battery is
completely empty. The duration between the first warning
signal and the end of operation can vary. Therefore,
we suggest that you replace the old battery immediately
after the first warning signal.
