For use in the United Kingdom and in Australia, use the optional
adapter TMEA P1-10 UK, Australian mains adapter. Connect the
adapter to the printer (see fig. 30). The indicator is now flashing slowly
with short gaps: the battery is being charged. When the red indicator is
permanently lighted, the battery is fully charged.
Note!
The printer can also be charged when turned OFF. In this case the red
indicator does not light.
