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 coasting 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.
