1-5-1 Keypad 
Keypad conventions 
Most keys have secondary functions , their functions are printed on the panel. However, 
due 
the restriction of available size, not all functions can be shown on the keypad printing.   
For the secondary functions of the AR-ONE, they are indicated with white characters above 
each key. To access the secondary function, push the FUNC key, and then push the 
respective key. 
 
1-5-2 Summary of keys 
 
ESC  
Push this key to cancel entry from the keypad. 
 
LOCK 
This key is intentionally small to reduce the chances of accidental operation. Key lock is 
useful when you do not wish an important frequency to be lost or the AR-ONE to be 
incorrectly set to a different frequency.   
 
MON 
The monitor key is used to force the squelch open so that you may manually intervene to 
ensure that no weak signals are missed.

1-6  Computer control 
 
Connect the AR-ONE to the serial port of a computer using an RS-232C serial cable 
terminated in a 9-pin male connector. The RS-232C parameters may be defined using the 
CONFIG menu. Baud rates (transfer speed) set to either 4800 or 9600 bps. Since there are 
two independent RS-232C port with the AR-ONE, it is possible to set an ‘address’ to 
facilitate connection of up to 99 AR-ONE to a single PC. 
 
The RS-232C parameters are as follows: 
Baud Rate:    4800 or 9600 bps 
De-limiter:      CR, LF 
Data bit:          8 bit 
Stop bit:            2 bit 
Parity:      None 
X parameter: ON 
 
1-7 IF output and Spectrum Display Unit (SDU5500, SDU5600 ) 
The rear panel has a 10.7 MHz IF output designed to drive the optional SDU5500 or 
SDU5600 Spectrum Display Unit. The SDU5500 or SDU5600 provides an excellent tool for 
locating elusive transmission with a PEAK capability to ‘freeze’ the briefest of transmissions 
for later measurement of frequency and level after the event.   
(Note: The IF output frequency is selectable in the 
CONFIG menu. (10.7 MHz or 455KHz).   
 
2 Getting started 
2-1 Making the AR-ONE ready for operation 
2-1-1 LCD (Liquid Crystal Display) 
All relevant operational information is provided via the LCD. The LCD contrast is 
adjustable.  
						

							 17 
 
2-1-2 Connect the antenna 
For reception on the all bands, connect the antenna to the N connector on the rear panel of   
the AR-ONE. An optional SA7000 Super Wideband Receiver is provided for this purpose. 
A receive frequency range of the SA7000 is 30 KHz ~ 2000 MHz. 
2-1-3 Connect power 
Connect the power to the DC power jack on the rear panel of the AR-ONE. Use either a 
supplied AC power adapter. Or a regulated DC power supply (12 ~ 14 V with capacity 2A)   
may be used. Do not connect to a 24 V system.   
 
                         Main Power Switch ___|    |___ DC Power Jack 
 
2-2 Switching On for the first time 
Set the squelch control to the ‘mid point’ . Turn the power switch on the rear panel of the   
AR-ONE. This is a main power switch. The Green LED lit on the switch. Then rotate the 
PWR/VOL control to the ‘mid point’, as you start to rotate the PWR/VOL control, a ‘click’ will 
be heard as the power isolation switch contact switches on. Please be careful NOT to 
switch 
on any receiver with an earphone connected, there may be an audible click when the unit is 
switched on or the volume may be accidentally set too high. 
          Power/VOL control   
                    
        
 
            
    Squelch control   
The AR-ONE will take approximately 1 - 2 seconds before the information appears on the  
						

							 18 
LCD. It is normal, for the microprocessor of the AR-ONE generates the ‘boot up data’ 
required to control the receiver. 
 
2-3 Squelch Circuit 
In normal use, NOISE SQUELCH
 is used. However, LEVEL SQUELCH
 can be selected for 
search and scan operations. The LEVEL SQUELCH
 parameter causes the AR-ONE to   
check the signal strength of 
active frequencies and to only stop when the signal strength is 
above a preset level (which is programmable). 
 
To select LEVEL SQUELCH
, perform the following steps: 
 
 
1.  Push the FUNC
 key. 
2.  Push the “8
” key. 
3.  On the bottom of the LCD, a bar will be displayed. Using the SQL 
control, 
adjust the desired signal level.   
4.  Push the ENT
 key to confirm entry.   
5.  Squelch will open only when the input signal strength is above this set level. 
6. To select NOISE SQUELCH
, repeat above steps. 
 
2-4 VFO selection 
The AR-ONE has ten (10) VFOs being identified as “V-A” through “V-J” on the top left of 
the  
LCD. The term VFO historically means 
‘Variable Frequency Oscillator’ and today refers 
to 
a tuneable data store which contains frequency, step, step-adjust, attenuator etc. Pushing 
the VFO
 key each time will select the one VFO out of 10.    The AR-ONE has an 
AUTOMODE setting, and therefore, in most cases a proper receive mode and frequency  
						

							 19 
step are automatically selected. 
 
2-4-1 Tuning frequency 
2-4-1-1 Entering a frequency using the numeric keypad 
While in VFO mode, enter the required frequency using MHz format followed by the ENT 
key. 
 
 
  Example of frequency entry of 80.8 MHz 
  Push the [8] key. Push the [0] key. Push the [.] key. Push the [8] key. Push the [ENT] key. 
 
  Example of frequency entry of 954 KHz (0.954 MHz) 
  Push the [.] key. Push the [9] key. Push the [5] key. Push the [4] key. Push the [ENT] key. 
 
Aborting frequency input 
If for some reason you do not wish to complete the frequency data input, push the ESC key 
before completing the input sequence with the ENT key. 
 
 
2-4-1-2 Changing frequency using the main tuning dial 
While in VFO mode, the active VFO frequency may be ‘tuned’ in using the rotary main 
tuning 
dial which is mounted on the right side of the front panel. You may rotate the dial ‘clockwise’ 
to increase frequency or turn ‘counterclockwise’ to decrease frequency.   
 
2-4-1-3 Changing frequency using UP arrow key or DOWN arrow key 
The UP arrow key and DOWN arrow key provide a convenient method of frequency 
change.
