8-9  Cyber Scan in SCAN mode
A special facility has been provided to speed up the
scanning process (which is capable of scanning about 25
memory channels per second), typically the speed
increases to about 45 channels per second.
When 
Cyber Scan has been selected the frequency and
text are blanked out from the display while scanning, the
words “CYBER SCAN” are displayed in their place.
While scanning the legend “SCAN” flashes to indicate that
SCAN is in...

9-2  SCAN - DELAY
The scan DELAY parameter affects the time the AR5000
will remain on an active channel in scan mode once the
received signal has disappeared and the squelch closed.
This is particularly useful for customising how long the
receiver will wait for a reply before continuing to scan.
For example, when communications are passed back and
forth between a control tower / aircraft which may take a
few seconds.  If you are scanning duplex channels then a...

selection process.  In fact the  key may be used as
a toggle between OFF and the new setting.
The legend “*” positioned to the right of the word “VOICE”
indicates that the current audio will open the squelch, use
the SUB DIAL to increase the value until the “*” legend
disappears, you can then be sure that the scan voice
setting will ignore and skip over the current frequency.
While in memory recall or scan mode, the LCD legend
“VCS” for voice squelch is displayed...

10-2  SELECT SCAN - while in SCAN
mode (tagging and un-tagging)
While the receiver is scanning, the AR5000 will stop on
active frequencies and you will soon realise that some
are 
interesting and some uninteresting.
To build up 
your select scan list of interesting channels,
start to 
tag the interesting channels while the scan
sequence pauses on active memory channels by pressing
 
The legend “S” will be displayed next to the bank number
of the memory channel to...

The right of the LCD will display the legend “* *” if select
scan channels exist and “- -” if there are none to delete.
To delete all select scan channels
(un-tag them all) press 
, the legend will change to
“- -” to confirm operation.
The memory channels themselves will not be deleted, only
the select scan tags will be removed
.  Press  
to
return to VFO, SCAN or SEARCH, whichever was
previously used.

The PRIORITY feature enables you to...

When the interval menu is selected the legend “P-INTER
05” is displayed (with 05 being the default of 5 seconds).
This numeric value in seconds determines how long the
AR5000 will wait between checking cycles before
re-sampling the priority frequency for activity (once the
priority facility has been activated).  The default is “05”
(5 seconds) and the acceptable range is 01 ~ 60 seconds.
Rotate the MAIN DIAL or SUB DIAL until the desired value is
displayed.  Once...

2  Select VFO-B.  Press the , the legend “VB” is
displayed on the lower right corner of the LCD.  Press
and hold the 
 
key for more than one second so
that the “AUTO” legend is displayed to ensure the AR5000
is in AUTOMODE (as each VFO can retain different mode
information).
Key the upper frequency limit into VFO-B.  In this example
136.000 MHz (the step size, mode etc will be taken care
of automatically as AUTOMODE is engaged).

2  To initiate simple frequency search (while “VC” or “VD”
or “VE” is displayed) press and hold the 
 
key for
more than one second (the 
 
or  
keys may
also be held for more than one second to initiate simple
search).
The squelch MUST be closed for the search process to
operate.
The simple search process will start from the displayed
frequency, the legend “SR” (SeaRch) will be added above
the VFO indication to show that SEARCH is in progress.
The MAIN DIAL, SUB...

VFO SEARCH - LEVEL SQUELCH
The LEVEL SQUELCH parameter causes the receiver
to check the signal strength of 
active frequencies and to
only stop when the signal strength is above a
predetermined level which is programmable in 256 steps.
The limits are OFF and 1 to 255 (default OFF).
Note: It is possible that false signal levels may upset the
operation of LEVEL SQUELCH due to local noise or the
close proximity of computer systems... the lower level
settings may not...
