number.
The maximum on-line time during two audio
sessions is disabled.
The line card listen in duration settings
overrides any control panel listen in
duration settings.
When pressing [CAN] during the two-way audio
session, the receiver prompts the operator to enter the
line number for stopping the two-way audio. Ensure
the D6600 is not in Menu Mode during this operation.
The OL/LF LED flashes green during the audio
session.
The D6600 prints the audio status on the printer with
the physical line number and sends the audio status to
the automation firmware with the physical line
number.
The D6600 decodes the first digit of the account
number to determine when to start two-way audio
operation. If the first digit of the account number
matches the selection, two-way audio activates.
