Charging
This phone is charged through the smaller Nokia standard interface (2.0 mm plug). The old standard charger
(3.5 mm) can be used together with the CA-44 charger adapter.

Charging is controlled by energy management, and external components are needed to protect the baseband
module against EMC, reverse polarity and transient frequency deviation.
Test pattern
The production test pattern is placed on the main board, accessible when the battery is removed from the
phone. The test points can be used for service and test purposes.
