Charging
This phone is charged through the µUSB interface only (there is no separate connector for a charger). Supported
are two charging modes for normal USB2.0 charging and Nokia uUSB AC-50 charger. Charging is controlled by
energy management, and external components are needed to protect the baseband module against EMC, reverse
polarity and transient frequency deviation.
