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. Although carefully designed, this receiver (like all receivers) suffers from a degree of internal noises known as spurious emission. They are a product of the receiver’s circuitry, and therefore, it does not represent a fault. Apparent faults may be due to accidental misoperation of the receiver. If you believe there is a problem, carefully read
6 all of the manual before deciding to contact your dealer for advice. It is acknowledged that sections of this manual are repetitive, this is to enable the manual to be used as a reference book (you don’t have to read it all from cover to cover in one go). Due to the international nature of the product, some graphics contain Japanese characters. Every effort has been made to make this manual correct and up to date. Due to continuous development of the receiver. and by error or omission anomalies may be found and this is acknowledged. © This manual is protected by copyright AOR, LTD. 2003. No information contained in this manual may be copied or transferred by any means without the prior written consent of AOR, LTD. AOR and the AOR logo are trademarks of AOR, LTD.

1-2 Take care of your radio
There are no internal operator adjustments. In the unlikely event of servicing being
required, please contact your dealer for technical assistance.
Do not use or leave the receiver in direct sunlight (especially the LCD). It is best to avoid
locations where excessive heat, humidity, dust and vibration are expected. 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.
Treat the AR-ONE with care, avoid spillage or leakage of liquids into the receiver and
associated power supply. Special care should be taken to avoid liquid entering around
the controls, through the speaker grille or via the connection jacks.
The AR-ONE is designed for operation from a good quality regulated DC supply of 12
to
14 V, which should be capable of supplying 1.5 amps. Never connect the AR-ONE
directly to the AC outlet.
The DC input jack is configured Center Positive, the chassis of the receiver is at
negative ground. Where provided (depending upon world market location), the power
supply is pre-wired and provides a nominal 12 V DC output with suitable connectors
being fitted as standard for the AC power input and connection to the AR-ONE.
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.
If using the AR-ONE in a base station situation, the best short wave reception is usually
achieved by the fitting of a separate external earth rod, however, consider the
implications carefully if your AC building supply uses a Protective Multiple Earth (PME)
system. If in doubt consult an expert electrician. Never earth to a gas pipe!
The AR-ONE has a single N type antenna connector for all frequencies. This is intended
for connection to a 50 ohm (unbalanced) coaxial fed antenna such as a discone, dipole,
8 unipole, Yagi, etc. When sighting the antenna, avoid power cables. Ensure that you do not confuse the antenna and other IF output connectors as they are closely located. Operating anomalies Should the AR-ONE appear to behave strangely, normal operation may be easily achieved by resetting the microprocessor. Two scenarios may be encountered due to power transients etc: 1. Symptom: LCD remains on, no control of the keypad. Action: Remove any connection to external power and leave it for approximately 30 seconds. Reconnect power and switch on again. Normal operation should be restored but the last used frequency will be lost, the AR-ONE will restore the last but one frequency to display. 2. Symptom: The AR-ONE fails to power up. Action: Try the suggestions given in (1) then hold the ESC key while powering up the AR-ONE to ‘Soft reset’ the microprocessor. 1-3 Attention while operating 1. Certain key operation are acted upon when the key is RELEASED, not while it is pressed. Allow time for the AR-ONE to register such actions before pressing another key. 2. The keylock (LOCK) is intentionally made to be difficult to operate to prevent accidental operation. To release keylock, the LOCK key has to be held for more than one second, the key icon on the LCD confirms operation. The LOCK is disabled during keying sequences (such as when entering frequencies). 3. If a key sequence is not completed, the microprocessor will automatically abort most operations after about 90 seconds of keypad inactivity. 4. Currently displayed VFO data is saved at power down (to increase speed of operation and to reduce write cycles). For this reason, if the AR-ONE is powered down using the PWR/VOL control or external power is removed, the last displayed frequency will be lost and the frequency used prior to this will be displayed when next powered up. Terminology – Search & Scan
9 If you have not used a wide band receiver before or not familiar with the terminology used, it is very important to understand the difference between SEARCH and SCAN modes. SEARCH: The AR-ONE provides several operations where transmissions (active frequencies) may be automatically located by sweeping the receiver over a wide frequency range, either from the currently displayed frequency traveling upwards (or downwards) in a specified tuning increment (step) or by sweeping over-and-over between two specified frequency limits. This process is known as SEARCHING, as the little implies, it can take a long time to find transmissions due to their ‘often intermittent’ and brief nature. For this reason it is best to slice large frequency ranges into smaller, more manageable pieces where they may be intensively studied. When examining large frequency bands, it is common to find that 90% of frequencies are inactive and only a small number of the remaining constitute what you really want. Searching still remains the best way to initially locate active and interesting transmissions (in conjunction with a good frequency listing and band plan). SCAN: Once active transmission have been identified (either by searching or by using a good frequency guide), it is more efficient to store the data into memories which can be rapidly and automatically monitored in succession stopping when activity is encountered. This forms a much more efficient means of monitoring the most wanted frequencies as you have targeted 100% what you most want to hear, by contrast searching is very inefficient for say-to-day monitoring. Note: It is very important that the squelch is advanced to cancel background noise for the search & 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. Advance the squelch control clockwise until the background noise is just cancelled, this is known as the threshold position. If the squelch control is advanced too far, weaker signals may be missed. No noise and no “S” icon displayed (with squelch advanced clockwise
