Velocitek S5 Instructions

Thank you for purchasing the Velocitek S5 GPS Race Computer! 

The S5 can provide you with the following information: 

•

Upwind and downwind velocity made good (VMG) in knots 

• 

Absolute maximum speed in knots 

• 

Fastest 10 second average speed in knots 

Speedometer Mode Operation 

1.  Open the waterproof case and turn on the S5 using the black plastic switch.  Make sure that you are looking 

at the LCD display when you activate the switch. 

When you first activate the switch, the display will show a number between 0 and 99 for about 3 seconds.  

This represents the amount of energy left in the device’s batteries.  99 represents fresh batteries and 0 

represents dead ones. 

2.  The display will then switch to showing the letters “OP” for Operating Mode.  This is a prompt for you to 

select the operating mode.  If you put your thumb over the “MAX / U”  button at startup when the device is 

showing the letters “OP”, the display will switch to the letters “SP” for Speedometer Mode (MAX / U 

stands for MAXimum Recall / Store Upwind reference point).  If you hold this button for one second until 

the display reads “00” the device will be configured to display speed in knots.   

You will be prompted to choose an operating mode every time you turn the S5 on.  If you do not press any 

buttons for three seconds once the “OP” prompt is displayed, the device will automatically revert to the 

mode used the last time the device was switched on.
