directly connected to the charger. The navigation device can be connected via the supplied USB cable to the power
output of
FastMute
Sonic Bike
.
b. VOX-control
The integrated VOX-control (Voice Operated eXchange)
prevents interference
between the audio playback. The
audio amplifier is
only activated when an incoming audio
signal is detected. After audio playback the amplifier is
switched to mute
. This prevents unpleasant noise in helmet. The
audio trigger threshold
can be adjusted
individually.
