Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Automatic Monitoring And Charging Of The Battery
The charge level of the battery (e.g. lithium ion battery) in the Bluetooth handset is established automatically by charge management in the eject box as soon as the Bluetooth handset is engaged in the eject box. The battery is then only charged when the charge management detects that the charge is below a specific level. The on-board supply voltage must also be available (from terminal R ON or during the run-on time).
