Charging
Note: The charging voltage and current can be checked by connecting the phone to the service soft-
ware and reading the ad- converter values of the vchar and ichar.
If charging fails when the ACP-9 or the LCH-9 is used, but works with ACP-7, ACP-8, and
LCH-8, check that the charge control pin of the system connector is connected to the
ground.
