Do I need to bear anything in mind if I am not using my on-board computer for a long time?
Remove the on-board computer (Intuvia, Kiox, Nyon) from the eBike and charge it fully before you put it away. When it is not being used, the on-board computer battery should be charged every three months to extend its service life as much as possible (if storage mode cannot be exited by pressing the on/off button, then recharge for the first time). You can put your on-board computer into an energy-saving storage mode, which reduces the discharging of the internal battery to a minimum. This resets the date and time. This mode can be activated by holding down the on/off button of the on-board computer (for at least eight seconds). You can turn the storage mode off again by pressing the on/off button and holding it down for at least two seconds.
