- SR.MODE
Pressing the  key places the receiver into program
search mode.  There are twenty search banks in total
numbered from 00 to 19.  To change the bank number
rotate the SUB DIAL, the bank number appears in the top
right of the LCD.  If the receiver stops on an unwanted
busy channel during search, it can be forced onward using
the 
  keys or MAIN DIAL.  To cancel search
press 
 again or press 
The key sequence   activates a sub menu
where bank link, pause,...

- OFFSET
Figure FIVE for the numeric input of frequencies, bank,
channel numbers etc.
The sequence 
  initiates FREQUENCY
OFFSET where the receiver will automatically jump to a
pre-programmed frequency offset, this is very useful for
checking the other side of duplex transmissions such as
the input frequency of amateur radio repeaters or VHF
marine traffic.
The sequence 
 
then hold the  key for more
than one second activates the FREQUENCY OFFSET
menu where new...

- CONFIG
This key is used to accept frequency input via the numeric
keypad in kHz format.  For example: To key in a frequency
of 954 kHz key 
    the LCD will display
954.000 kHz.  This has the same effect as keying
0.954MHz or .954MHz
Note: keying a decimal 
 before the number causes a
preceding zero to be added automatically.
The kHz method of frequency entry reduces the number
of key presses required when working with low frequencies
and simplifies operation...

The  key also allows selection On/Off of certain
options while in menus (such as step-adjust) and selects
defaults in other menus.
 - 
[MHz] [ENT] - TXT (Cyber Scan)
This key has three main applications:
MHz - the key is used to enter frequencies as MHz while
in VFO mode.  For example to enter a frequency of 88.300
MHz follow the key sequence 
    
There is no need to add the trailing zeros to the right,
once the 
 key has been used, the AR5000
microprocessor...

If held for more than one second while in VFO mode, a
frequency search is initiated.  If held for more than one
second while in memory recall mode, the scan process
will start.
INCREMENT - the key will often increment menu options
such as DTMF to T.ELMT etc.  While in TEXT write mode,
the 
 key will move the cursor one space to the left.

5-16  EXT SP - external speaker socket
This 3.5mm mono jack socket provides audio output to
drive an external speaker unit.  Connection to this socket
automatically disables the internal speaker but not a
headphone if connected to the front panel socket.
An external speaker should...

5-21  ANT 2
This is the secondary aerial (antenna) input for the AR5000
receiver.  It may be controlled from the front panel or
programmed to switch automatically.
The socket is a 50 OHM SO239 type and
the corresponding plug is the PL259.  Many off the shelf
inter-series adapters are available for connection to BNC,
N-type or other types of aerial termination.

This is the primary aerial (antenna) input for the AR5000
receiver.  It may be controlled...

VFO-E  Accept the frequency from the scan mode
If a frequency is keyed in to VFO-E and the  key
held for more than one second the search process will
commence from the displayed frequency.
If 
 is pressed while in SCAN MODE, the active
frequency will be transferred to VFO-E, the AR5000 will
switch to VFO-E automatically where you may monitor
and tune from the selected frequency.
Note:  If you press the VFO key for one second
or longer, SEARCH will be activated....

Providing the AUTOMODE facility has been engaged
(so that the “AUTO” legend is displayed above the right
hand digit of frequency readout), you may monitor the
frequency or tune the receiver using the MAIN DIAL or
SUB DIAL.  The AR5000 microprocessor will automatically
select the appropriate tuning increment, mode and I.F.

pre-programmed into the receiver (specific to each world
market area).  If automode is not...

Note:  The MAIN DIAL is a mechanical encoder and as
such small variations in tuning may be experienced or the
frequency may move slightly after rotation, this is normal.
To ensure the best life span and smoothest operation,
rotate the control from time to time to ensure the encoder’s
track remains clean.
SUB DIAL
The SUB DIAL can also be used to select the receive
frequency in three different ways:
l   Same step size as the MAIN DIAL
l  10 times faster than the...
