  • Page 3: Installing Batteries

    Installing Batteries The S10 uses two AAA batteries. Commonly available rechargeable Nickel Metal Hydride (NiMH) batteries are recommended. Two 750mAh NiMH cells will provide approximately 10 hours of battery life. Disposable alkaline batteries will also work although they will have a somewhat shorter life.
  • Page 4 Turning on the S10 for the First Time Open the waterproof case and turn on the S10 using the black power switch. The figure “Inside the Waterproof Case” at the beginning of this document shows the location of this switch.
  • Page 5: Operating Modes

    Operating Modes The S10 has the following two operating modes: • Speedometer Mode • VMG mode The decimal point after the second digit in the display is used to indicate which mode the device is in. To change modes: In VMG mode, performing this same procedure will return the device to speedometer mode.
  • Page 6 Speedometer Mode In speedometer mode the device will show your speed in knots, updated every second. The device also records your maximum speed and your best 10 second average speed. Note: If your maximum speed is greater than 9.9 knots the display will blink back and forth between the whole number and decimal portions of your maximum speed.

  • Page 8: Vmg Mode

    VMG Mode The S10 calculates your VMG based on a wind direction that you set using upwind and downwind reference points. When the wind shifts from the direction you set, the accuracy of the S10’s VMG measurements is reduced. For shifts of less than 10 degrees in either direction, however, optimizing the value displayed by the S10 will still get you very close to optimizing your true VMG.
  • Page 9 Using Reference Points to Enter the Wind Direction Enter the wind direction into the S10 as follows: You have now given the device two reference points that define the wind direction. The device has stored the geographical coordinates of the two reference points and assumes that the wind direction is the same as the heading from the downwind point to the upwind point.
  • Page 10 Logging GPS Data Whenever the S10 is turned on and has a GPS solution (i.e. when the display is showing speed or VMG and not flashing “00”) it will record the following data in its built in flash memory at two second intervals: •...
  • Page 11 Section of this document below. Clearing GPS Data from Flash Memory To erase all the GPS data in the S10’s flash memory and make room for new data: 1. Open the plastic case and turn the device off. 2. Press and hold the black plastic pushbutton in the bottom left corner of the circuit board.
  • Page 12: Frequently Asked Questions

    Frequently Asked Questions What is VMG? A good way to understand Velocity Made Good (VMG) is to imagine a power boat and a windsurfer traveling from a leeward (downwind) mark to a windward (upwind) mark together. The powerboat travels along a straight line between the marks while the sailor tacks back and forth to get upwind.
  • Page 13: Fcc Compliance Statement

    In speedometer mode the accuracy of the S10 is better than +/- 0.2 knots (0.36 km/h). In VMG mode accuracy of the S10 depends on what angle to the wind you are sailing but is generally better than +/- 1 knot (normally closer to +/- .3 knots).
