IMPORTANT: ZERO TORQUE Frequently the torque must be zeroed to ensure the most accurate power information is displayed. If the current power display is positive or negative while coasting the the torque must be zeroed. This operation must be done while stopped with no tension on the chain, no tension placed on the pedals, and the transmission icon must be illuminated. To zero torque:
1) Press [MODE] to scroll the cursor to the top line of the main display. 2) Press [SELECT] until current power function is displayed.
3) Hold [SELECT] until the word “WATTS” begins to flash to enter the torque function.
4) Hold [SELECT ] again until “0” is shown.
5) Press [SELECT] to return to current power.The current power function will now read zero while coasting.
