directory
The system accesses the telephone's
contacts directory, depending on
its compatibility, and while it is
connected by Bluetooth.

saved in a permanent directory
visible to all, whatever the telephone
connected.

accessible if it is empty.

SRC for access to the directory
or press OK, and
select "Call" and confirm.

contacts.
To modify the contacts saved in the
system, press MENU then select
"Telephone" and confirm.

and confirm.
