    1-1 Introduction Thank you for purchasing the AR-ONE Ultra Wide Band Communications receiver. The AR-ONE is designed using the very latest technology to ensure the highest levels of performance and reliability. To get the best possible results from your AR-ONE, we strongly recommend you to read this manual and familiarize yourself with the receiver.

  • Page 6: Taking Care Of Your Radio

    Always keep the AR-ONE free from dust and moisture. Use a soft, dry cloth to gently wipe the set clean, never use abrasive cleaners or organic solvents which may damage certain parts.

  • Page 7: Attention While Operating

    SAFETY NOTICE – Always disconnect the power supply from the AC outlet when not in use. If used mobile, it should be noted that the AR-ONE has NOT been manufactured or tested to meet any specific mobile safety requirements. The AR-ONE has no internally user adjustable parts.
  • Page 8 & scan functions to operate. This is because the AR-ONE believes that it has found an active frequency when the squelch opens and “S” ‘squelch open’ icon is displayed to the left of the signal meter.

    AR-ONE receiver DC power cable Operating manual 1-5 Controls & functions Controls are located on the front with most connectors on the rear of the AR-ONE, a brief identification is given here: Front Panel 1. Volume control plus isolate power On/Off 2.
  • Page 10 The REMOTE RS-232C connectors (17 & 18 above) are designed for connection directly to a RS-232C serial port of a PC. By daisy chaining the units, control of up to 99 AR-ONE receivers is possible from one PC. No interface is required, just a standard RS-232C straight cable.

  • Page 11: 1-5-1Keypad

    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. To force the squelch open so that you may manually intervene to ensure that no weak signals are missed.

    CONFIG menu. Baud rates (transfer speed) can be set to 9600, 19200 (default) or 38400 bps. Since there are two independent RS-232C ports with the AR-ONE, it is possible to set an ‘address’ to facilitate connection of up to 99 AR-ONE receivers to a single PC.

  • Page 14: Getting Started

    2-1-3 Connect power Connect power to the DC power jack on the rear panel of the AR-ONE. For optimal performance use a regulated DC power supply (12 ~ 14 V with capacity 2A). Do not connect to a 24 V system.

  • Page 15: Squelch Circuit

    The AR-ONE will take approximately 4 - 5 seconds before information appears on the LCD. This is normal, while the AR-ONE microprocessor 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.

  • Page 16: Vfo Selection

    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 tunable data store which contains frequency, step, step-adjust, attenuator etc.

  • Page 17: Changing Frequency Using The Main Tuning Dial

    For your convenience, receive mode and tuning step size have been pre-programmed into the AR-ONE auto-mode band plan data at the factory to simplify operation of the receiver, especially while you familiarize yourself with all functions. Should you wish, the defaults may be manually overridden at anytime so that you may select an alternative receive mode and tuning step on any frequency.

  • Page 18: Auto Mode Selection

    WFM – Wide Band Frequency Modulation – used by VHF and UHF broadcast stations as excellent audio quality is available due to the relatively wide frequency bandwidth employed. Used only for local services such as VHF band stereo (received as mono on the AR-ONE) and UHF TV sound channels.

  • Page 19: Receive Mode Selection

    Note: Auto-mode is cancelled as soon as the receive mode, tuning step or other related data is changed. Remember that auto-STEP and auto-MODE are linked, reselect AUTO-MODE if either have been adjusted and you require the auto band plan selection. 2-5-2 Receive mode selection Any receive mode may be selected at any frequency within the receiver’s frequency coverage.

  • Page 20: If Bandwidth

    The bottom line of the LCD displays the icon “STEP SET” to indicate that the AR-ONE is Waiting for you to change the step size. Use the main tuning dial or arrow key to select the desired step size. To accept the displayed tuning step size, push the ENT key.

  • Page 21: Manually Selecting If Bandwidth

    An appropriate IF filter is automatically selected when auto mode is engaged. However any combination of IF filter and receive mode is possible in manual mode. When you have manually selected an IF filter bandwidth, auto mode will be disengaged, but the receive mode, step size, etc will be retained until they are changed manually.

  • Page 22: Att (Attenuator)

    When MANU is selected, a desired parameter can be entered between 0 ~ 255 in the Configuration Menu. 2-9 ATTENUATOR Activating the attenuator reduces signals to the RF input stages of the AR-ONE to prevent overloading, for example when the receiver is used in close proximity to strong transmissions.

  • Page 24: Offset

    2-11 OFFSET This function enables the receive frequency to be quickly SHIFTED by a predetermined value, this makes it easy to track duplex-transmissions or check repeater inputs/outputs. The locations for frequency offset storage are numbered 00 to 47 with 00 acting as OFF, this makes 47 locations available.

  • Page 25: Memory Channels And Banks

    Think of memory channels as pages in a notebook, each of which is numbered to identify it. Data may be written to each new page (memory channel) and each page may be overwritten with new data, they can be used over and over again. The AR-ONE has 1,000 memory channels and one priority channel.

  • Page 26: Storing Vfo Frequency And Data Into Memory

    100 channels. The memory banks are identified by the first BANK number 0, 1, 2, 3, 4, 5, 6. 7, 8 and 9 and the individual channels are numbered from 00 to 99. Examples are “000” for the first channel location in memory bank “0” and “099” for the last memory channel in memory bank “0”.

  • Page 28: Deleting Memory Channels

    The AR-ONE will display memory channel, mode, text comment (if one was used). The memory channel last used (for memory write or recall) will initially be displayed. If the desired memory channel is not immediately displayed, it may be recalled by keying in the required three digit location.

  • Page 29: Scan - Scanning Memory Channels

    During SCAN, the AR-ONE automatically recalls memory channels which contains data in numeric order and monitors them looking for activity. When an ‘active’ memory channel is located (when a signal is found and the squelch is open), the AR-ONE will temporarily stop scanning.

  • Page 30: Selecting A Scan Bank

    When SCAN has been selected, only the currently displayed memory bank WHICH CONTAINS DATA will be SCANNED, receive mode and frequency are unimportant. Any memory channels which contain no data (empty) will be ignored (skipped). 4-3 Selecting a scan bank The memory bank identifier (such as “3”) will be displayed on the middle right of the LCD.

  • Page 31: Search Mode

    To stop select scan, push the VFO key. 5 Search mode In search mode, the AR-ONE is programmed to automatically tune between two specified frequency limits looking for activity. Please refer to section 1-3 of this manual if you do not fully understand the function of SEARCH.
