The on-board computer of your Carqon is powered by the Bosch battery. Your Carqon bike might be equipped with a Bosch Purion display or a Bosch Intuvia Display. There is a slight difference in charging the Bosch Purion display, compared to the Bosch Intuvia display.
Bosch Intuvia Display
If the on-board computer is removed from the holder, the energy is supplied via an internal battery. If the internal battery is weak and the on-board computer is switched on, <Attach to bike> will appear on the text indicator for 3 seconds. The on-board computer will then turn off again. To charge the internal battery, put the on-board computer back in the holder. The on-board computer will recharge while riding.
Please note; the Bosch Intuvia Display has an internal battery, that will be recharged automatically, while riding your bike.
Bosch Purion Display
If the on-board computer shows LOW BAT on the display, remove the on-board computer from the handlebars by unscrewing the fastening screw of the on-board computer. Open the battery compartment cover using a suitable coin, remove the used batteries and insert new CR2016 batteries. You can obtain the batteries recommended by Bosch from your Carqon dealer. When inserting the batteries, ensure that the polarity is correct.
