If you still have difficulties after following the instructions in this section, disconnect 
the base unit’s AC adaptor and turn off the handset, then reconnect the base unit’s 
AC adaptor and turn on the handset.

turn on even after 
installing charged 
batteries.

your service provider/telephone company.
