It will be activated again by pressing the MODE button or moving the bike. Work mode We select this option using the MODE button. By pressing START we switch from ON to OFF and viceversa. When it is on, the screen displays the symbol and data are gathered to calculate the information displayed on screen in the Elapsed Time, Trip Distance, Max Speed and Average Speed functions. When OFF is selected, it stops capturing data and calculating, but the values are not lost and may be visualised at any time by selecting the corresponding function. The values will be automatically reset by reactivating the Work mode (ON). Elapsed time The Elapsed Time function displays the time passed since the last time the work mode was activated.
