7.3.3 Key Sound Volume
/ Switch
The switch on the left can
turn the key sounds on or
off. Key sounds are audible
confirmations of either pressing
hardware buttons or tapping the
touch screen. When key sounds
are turned on, the slider on the
right will adjust their loudness.
In its leftmost position the key
sounds are suppressed; in
its rightmost position they are
played at the master volume
level.
NOTE :
The sound effects of this
Navigator are context
sensitive. They will be different
if, for example you open or
close a window, or you enable
or disable a setting. It will
even let you know if you have
entered enough letters of a
street name to have a short
list of matches on the screen.
7.3.4 Dynamic Volume
When driving at high speed,
the noise in the car may be
too loud to clearly understand
the voice guidance messages
and perceive the key sounds.
Using Dynamic Volume you
can instruct this Navigator
to increase the volume to its
highest level when your speed
exceeds a certain minimum and
macimum speed (determined
by the Master volume slider in
sound settings).
Tap the Dynamic volume button
to turn on the feature. This will
also open the screen where
you can set the minimum and
maximum speeds.
7.3.5 Attention Tone
If this is set to Disabled, the
voice guidance will sound
without a preceding attention
tone. Setting it to Single Tone
will initiate a single attention
tone before the instructions,
while Double Tone will use a
double tone.
