Operation
The DIR911t always operates in one of three modes: MAIN, RECALL, and SYSTEM.
The main mode is where the unit spends most of its time and is the mode in which the
unit enters upon power-up and when the system or recall modes are exited.
The recall mode is used to playback a recorded call under scrutiny. This is where, when
playing back a file, the user may move about the playback, pause the playback, adjust the
filter parameters of the playback, etc. This mode is entered any time the RECALL key is
pressed.
The system mode is used to configure system and line specific parameters. This is where
the LAN is setup, the line recording parameters and triggers are setup, internal firmware
updates are performed, etc. The system mode is entered anytime the SYSTEM key is
pressed (unless the unit is already in SYSTEM mode, in which case it is ignored).
Each of these modes is discussed in detail in the sections that follow.
Main Mode
The main mode is entered when the system is powered on or when either the recall or
system modes are exited. The normal mode screen is shown in Figure #6

Figure 6: Main Screen
The main mode screen contains a few elements worth noting:
• The current date and time is shown in the upper left hand corner of the screen. If
the unit is configured to synchronize its time to the network and it cannot obtain
or maintain synchronization, it will alternately flash the current time and a “No
External Sync” message.
• If system alerts are present an “ALERT” message will be flashing on the top line
between the date and the call number. More details about the alert can be
obtained from the ALERT menu described later in this manual.
