AOR AR8000 Operating Manual page 66

It is strongly recommended that NEWUSER mode is used during
familiarisation of the AR8000, use EXPERT status only if you have
fully familiarised yourself with all operations.
To select EXPERT configuration the CONFIGURATION menu is used. To
access the menu press [FUNC] [LOCAL] and the "INITIAL SET" menu will be
displayed.
Select the NEWUSER/EXPERT option of the fourth line of the LCD, the cursor
will be to the right of the "NEWUSER" setting which is the default. To change
the setting to "EXPERT" rotate the [DIAL] (on the top panel) one click, the
direction is unimportant. The legend "EXPERT" confirms selection.
The new setting may be saved by pressing [ENT] at this point.
If you have selected "EXPERT" status then further options become available by
pressing the [DOWN] key. These include AUTO-STORE, POWER-SAVE and
REMOTE. These options are covered later in the operating manual.
To access the additional options of "SET M-SCAN"
Once in EXPERT status five additional options are available. To access the
"SET M-SCAN" menu first place the receiver into SCAN mode ("SCAN"
displayed in the top left of the LCD) then press [FUNC] [SCAN].
Press the [DOWN] key three times (only one press is required if bank link is
OFF) to select the first of the five options. Continue using the [DOWN] key
until the required option is selected. When you are happy with the changes
press [ENT] to accept the changes and the receiver will revert to SCAN mode.
Note: Make small changes and assess the effect as incorrect setting may
degrade the effectiveness of SCAN capabilities. If things appear to go
wrong, return the settings to their defaults or return to NEWUSER mode
which forces the AR8000 back to SCAN defaults.
In extreme cases, reset the microprocessor which will revert the scan
options back to defaults by placing the receiver into NEWUSER mode.
SCAN - DELAY time
The DELAY scan parameter affects the time the receiver 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 fore between a control tower / aircraft which may take a few
seconds. If you are scanning duplex channels then a small delay or no delay at
all may be preferable.
The limits are 0.0 to 9.9 seconds with 0.0 being interpreted as DELAY OFF.
