tus of FWT after power-off. The power supply icon
and a blinking battery icon indicate that the battery is
being charged.

If you are not in a call, you can answer the call.

you are ready to dial or are dialing a phone num-
ber.

not in a conversation, you can answer the call.
There is only the battery icon on the display
screen.
