Priority Operation; Engaging Priority Operation - AOR AR8000 Operating Manual

(12) Priority operation

The PRIORITY feature enables you to carry on scanning, searching or
monitoring while the AR8000 checks a frequency taken from one of the 1000
memory channels (A00 default) every 5 seconds (default) for activity.
The priority checking is accomplished by momentarily moving to the priority
frequency to see if it is "active". If activity is found, the receiver remains on the
frequency until the signal disappears. If no activity is detected, the receiver
returns to the VFO frequency, scan channel or search bank from where it
originated.
The priority facility has a large number of applications and is particularly useful
for keeping an eye on a distress frequency while scanning or searching another
frequency band.
Note: Depending upon the frequency and mode stored as priority, an
audible "click" may be heard when the priority facility is in operation.
This is quite normal and is caused by the internal switching of circuitry
necessary to accomplish the frequency change as two frequencies
cannot simultaneously be monitored by the receiver.
The priority mode is automatically suspended during entry of frequencies via
the keypad, this prevents the receiver from changing frequency while you are
busy programming.
Note: Selecting priority operation while displaying the BAND SCOPE will cause
the band scope to be cancelled and will return the receiver to 2VFO mode twin
frequency display.
12-1 Engaging PRIORITY channel
Once engaged, the default channel used for PRIORITY is "A00" and the
frequency is checked for activity every 5 seconds.
First ensure that there is data stored in memory channel "A00".
To engage the priority facility press [FUNC] [4]. This may be carried out while
in SCAN, SEARCH or VFO modes. The legend "P" appears toward the centre
of the top line of the LCD to indicate that PRIORITY IS ENGAGED (switched
On).
Once priority has been activated, the data contents of the memory channel
used (default A00) may be altered without affecting
the data used for PRIORITY operation which is
stored separately and assumes an identity of its own
irrespective of the data contents of memory A00.
Should you subsequently wish to alter the priority
data, you will have to use the "SET PRI CH" menu
detailed in 12-2 of this manual.
