(constant power without the key on) See
the Preferences section for details.

After the SC55’s start-up sequence is
completed, the display will provide a
speed and compass screen. Once your
vehicle is moving, your vehicle speed and
heading will be provided.
If you prefer, you can select alternate
power-on indicators. See Preferences.
NOTE: You must be moving and
have an acquired GPS signal for this
information to be presented.

The GPS icon is visible on the right side of
the SC55 display, and indicates whether it
is receiving GPS signals. At start-up, this
icon will flash on and off until GPS data is
received. Once it receives the signals, this
icon will stop flashing and remain on the
display

a speed (30-95 mph) as a reminder of how

reached, an audible alert and warning
message will appear
.
