Distance to line is the perpendicular distance from the SC-1 to the user defined start-line of the SC-1 in
meters. The distance is calculated off of the GPS unit latitude and longitude measurements.
Button Locking and Unlocking
The Velocitek SC-1 uses touch sensors to accept user input. Splashing water can trigger the touch
sensors. To prevent the device from being inadvertently controlled by splashing water the device locks,
or does not accept button inputs, when the indicated speed exceeds the
speed lock value
. At speeds
below the speed lock value, the buttons are unlocked and will accept user input. The lock feature can
be customized by connecting the SC-1 to a PC. By default the locking is enabled with a speed lock value
of 2.0 knots.
Clearing Start-line
Start-line end locations are cleared every time the SC-1 is powered off or disconnected from a computer.
Clearing the Maximum Speed
Both instantaneous and 10 second maximum speeds are cleared from memory every time the SC-1 is
powered off or disconnected from a computer.
Device Settings
