FANS AURAL
Works in conjunction with the FANS
AURAL output discrete and controls the
duration of the FANS AURAL alert.
The default value is set to 0MS, which
means that the Alerting device will
remain active until the message that
activated the alert has been viewed.
Therefore, it is recommended to set this
time duration to some other value than
0MS. A value such as 5000MS
(5 seconds) may be suitable in most
cases.
It is recommended to set this time
duration to a specific value required to
support correct operation of the aural
alerting device, for example a
SONALERT or Aural Warning
Generating equipment.
A
value of zero is not recommended as it
can result in the loss of aural alerts from
a new message received if an unread
CPDLC message already exists. A value
such as 5000MS (5 seconds) may be
suitable in most cases
