    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. 
     
    FUNC 
    The function key is used to select the secondary function of keypad. 
     
    SCAN

    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.
