The Nokia 9000 Communicator’s applications for
PC connectivity (File transfer, Install/Remove
software, Backup/Restore, Import/Export con-
tacts, Import/Export calendar data) enable you to
connect to a PC. The Security application lets you
determine the level of system security and
change security codes (see "Security").
Note:
When one of the PC connection applica-
tions or the fax modem application is activated,
the communicator consumes more power than

these applications should be closed when they
are not in use.
