LOCAL OPERATION
WJ-8711A DIGITAL HF RECEIVER
3-40
A lockout frequency can be added to the list during a paused scan by setting the tuned
frequency display to the desired frequency, then press the FREQUENCY LOCKOUT key. The scan setup
display does not have to be entered to store a new lockout frequency. After the lockout frequency is stored,
the message "LCKOUT STORED" is displayed for a period of three seconds, after which time the
Memory/Scan display returns to the previous display. If no lockout channels are available (i.e., 100 lockouts
are already entered), the message "MEMORY FULL" is temporarily displayed.
A lockout frequency can also be deleted from the list. To delete a lockout, scroll through the
scan setup display until the lockout frequency is displayed, then press the CLEAR key.
Foldout FO-4
provides an example of setting up and executing an F1
→
- F2 scan operation
including steps for entering and clearing lockout frequencies.

PLACING THE RECEIVER IN SCAN MODE
Once a scan setup has been entered, the receiver can be placed into the scan mode. To start a
scan, first select the type of scan with the SCAN TYPE key, then press the SCAN key. The scan is started
when the SCAN key LED is lit.
NOTE
When the channel scan is started, both Auxiliary
Parameter displays are blanked until a signal is acquired.
3.8.4
PAUSING AND RESTARTING SCANS
An active scan operation can be paused by pressing the PAUSE key. When the scan is
paused, the PAUSE key LED is lit and the displays indicate the current tuned frequency and auxiliary
parameters of the receiver. The scan can be restarted by pressing the PAUSE key again, extinguishing its
LED. When a paused scan operation is restarted, the scan operation resumes at the next step in the scan
sequence after which it was paused. For example, when a channel scan operation is paused, the channel to
which the receiver is currently tuned is displayed. When the scan is restarted the scan resumes at the next
channel in the scan sequence.
When paused, the receiver acts as if it is in the Manual mode. Receiver parameters can be
adjusted to look more closely at a received signal. When a scan is restarted, tuned frequency adjustments are
ignored and the scan resumes according to the programmed scan setup. However, changes and adjustments to
auxiliary parameters are maintained.
Also, when paused, scan setup parameters can be changed. Lockout frequencies can be added
with the FREQUENCY LOCKOUT key or can be deleted in the scan setup menu. The step size can be
changed with the STEP SIZE key or in the scan setup menu.
