1-2 TAKING CARE OF YOUR RECEIVER
There are no internal operator adjustments needed. In the unlikely event a service is required, please
contact us for technical assistance.
Do not use or leave the receiver in direct sunlight. It is best to avoid locations where excessive heat,
humidity, dust, and vibrations are present. Always keep the AR-DV1 free from dust and moisture. Use a
soft, dry cloth to gently wipe the external surfaces clean; never use abrasive cleaners or organic solvents
which may damage certain parts.
Treat the AR-DV1 with care; avoid spilling liquids into the receiver and the associated power supply.
Special care should be taken to avoid liquids from entering the area around the controls and through the
speaker grill or via the connection jacks.
The AR-DV1 is designed to operate from a good quality regulated DC power supply of 10.8 to
16.0 V, which should be capable of supplying 1 amp. Never connect the AR-DV1 directly to an AC power
outlet.
The polarity of the DC input jack is clearly marked; the chassis of the receiver is at negative ground.
SAFETY NOTICE – Always disconnect the power supply from the AC outlet or switch off
the power switch when the receiver is not in use for a long period of time. If used mobile,
note that the AR-DV1 has NOT been manufactured or tested to meet any specific mobile
safety requirements. The AR-DV1 has no user adjustable internal parts.
When using the AR-DV1 as a base station, the best short wave reception is usually achieved through the
use of a separate external earth (or ground) rod. However, consider the implications carefully if your AC
building supply uses a Protective Multiple Earth (PME) system. If in doubt, consult a qualified electrician.
Never earth (ground) to a gas pipe! The antenna connector of the AR-DV1 is intended for connection to a
50 ohm (unbalanced) coaxial fed antenna such as a discone, dipole, Yagi, etc.
Avoid power cables when installing an antenna.
Operating anomalies
Should the AR-DV1 appear to behave strangely, normal operations may be easily achieved by performing
the following steps:
1. Symptom: No control of the receiver
Action: Turn off the power switch on the front panel. Leave it off for approximately 10 seconds.
Turn the power switch back on again. Normal operation should be restored.
2. Symptom: The display freezes.
Action: Turn off the main power switch on the rear panel. Leave it off for approximately 10
seconds. Turn the power switch back on again. Normal operation should be restored.

Terminology
Search & Scan
If this is your first time using a wide band receiver or you are not familiar with the terminology used, it is very
important to understand the difference between SEARCH and SCAN modes.
SEARCH: The AR-DV1 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 name implies, this process 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 intensely monitored.
When examining large frequency segments, it is common to find that 90% of the 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 transmissions 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 is a much more
efficient means of monitoring the most wanted frequencies as you have targeted 100% of what you
most want to hear. By contrast, searching is very inefficient for day-to-day monitoring.
Note: For the search & scan functions to operate properly, it is very important to advance the
squelch to cancel background noise. This is because the AR-DV1 believes that it has found an
active frequency when the squelch opens and the “BUSY” indicator lights up. 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.

GETTING STARTED
3-1 MAKING THE AR-DV1 READY FOR OPERATION
3-1-1 CONNECT THE ANTENNA
For reception on the all bands, connect the antenna to the antenna connector on the rear panel
of the AR-DV1.
3-1-2 CONNECT POWER
Connect the power to the DC power jack on the rear panel of the AR-DV1.
A supplied AC power adapter (part number: AA8600) or a regulated DC power supply (10.7 ~ 16.0 V with
capacity 1A) may be used. Do not connect to a 24 V system.
The clock will be displayed on the LCD.
(Note: To use the clock function, a power adapter must be always connected and applied the power to
the AR-DV1.)
3-2 SWITCHING ON FOR THE FIRST TIME
Press the volume knob on the front panel of the AR-DV1. This is the power switch.
As you push the volume knob, a ‘click’ will be heard.
Please be careful NOT to switch on the receiver with an earphone connected because there may be an
audible click when the unit is switched on and the volume may be accidentally set too high.
15
Opening screen
(Note: The version number may vary.)
After the opening screen appears on the LCD, the main screen will then be displayed.
It will take approximately eight seconds before the main screen appears. This is a normal process to
initialize the AR-DV1.
To power off the AR-DV1, push and hold the power switch on the front panel for about two seconds.
After “AR-DV1 SHUTDOWN” message is displayed, the receiver will automatically power off.
3-3 VOLUME CONTROL
To change the volume (audio) level, rotate the volume control knob clockwise to increase, and
counterclockwise to decrease. The audio level bar will be indicated on the LCD.
16
3-4 SQUELCH CONTROL
To change the squelch level, rotate the squelch control knob clockwise to increase, and counterclockwise
to decrease. The squelch level will be indicated on the LCD.
After setting the squelch level, the LCD will return to original display.
While squelch opens, “B” (busy) will appear in reverse contrast on the middle left of the LCD.
3-5 VFO SELECTION
The AR-DV1 has three (3) VFOs identified as “VFO-A”, “VFO-B” and “VFO-Z” on the middle left of the
LCD.
The term VFO means ‘Variable Frequency Oscillator’, which today refers to a tunable data storage
which contains frequency, step, step-adjust, attenuator etc. Pressing the [VFO] key each time will toggle

(Example) Frequency entry of 81.3 MHz
Press the [8] key. Press the [1] key. Press the [.] key. Press the [3] key. Press the [ENT] key.
(Example) Frequency entry of 1.134 MHz (1134 kHz)
Press the [1] key. Press the [.] key. Press the [1] key. Press the [3] key. Press the [4] key. Press the
[ENT] key.
Correcting frequency input
Press the [CLR] key to delete the entry from the right hand side.
3-5-1-2 CHANGING FREQUENCY USING THE MAIN DIAL
In VFO mode, the active VFO frequency may be ‘tuned’ in by using the tuning dial mounted on the right
side of the front panel. Rotate the dial ‘clockwise’ to increase the frequency or 'counterclockwise’ to
decrease the frequency.
3-5-1-3 CHANGING FREQUENCY USING [UP] KEY OR [DOWN] KEY
The [▼] key and [▲] key provide a convenient way to change the frequency.
The speed the receiver steps up and down will depend on the step size.
In auto- mode, the step size, receiver mode, etc. are taken from the factory pre-programmed band plan
but may be overridden at any time.
Press the [▲] key to tune the receiver upward in the step size selected, and uses the [▼] key to tune the
receiver downward in frequency.
18
3-5-1-4 VFO COPY
In VFO mode, press the [F] key and then the [PASS] key to copy between two VFO’s frequencies.
(While receiving frequency on VFO-Z, copy it to VFO-B)
The original VFO must always be VFO-Z. The destination can either be VFO-A or VFO-B, which can be
selected by rotating the dial knob.
To confirm selection, press the [ENT] key.
3-6 RECEIVE MODE
Due to the necessities of signal bandwidth, channel occupancy, and transmission efficiency, different
receive modes are used by various services. The receive mode and tuning step may vary throughout the
world depending on the country’s international agreements and guidelines. For this reason, it is necessary
to change these settings to monitor various transmissions.
For your convenience, the receive mode and tuning step size have been pre-programmed into the AR-DV1
auto mode band plan data to simplify the operations of this receiver, especially while you familiarize
yourself with its functions. If needed, you may override the defaults and select an alternative receive mode
and tuning step on any frequency.
AM – Amplitude Modulation
Used by broadcast services throughout the world on long-, medium-, and shortwave.
AM is also used by VHF airband, and UHF military airband.
SAM – Synchronous AM
Helps listen to SW (Shortwave) AM broadcast stations with fading signals.
FM – There are two common types of FM (Frequency Modulation):
NFM – Narrow Band Frequency Modulation
Provides high quality communication for relatively short distance operations.
FM uses a greater frequency bandwidth than other modes.
NFM is the most common mode used above 30 MHz with the exception of the airbands. NFM is
widely used on the VHF bands: VHF marine band, 2m amateur band, 70 cm amateur band, PMR
(Private Mobile Radio) and utilities.
19
In the absence of a signal, the background white noise may appear quite loud. For easier listening,
the squelch control should be rotated clockwise until the background noise disappears; this should
be carried out while no signal is present. The point at which the background noise is cancelled is
known as the threshold point. Do not advance the squelch control more than necessary or the
receiver will appear to be desensitized and weaker signals will be missed.
WFM – Wide Band Frequency Modulation
Used by VHF and UHF broadcast stations as excellent audio quality.
This is available due to the relatively wide frequency bandwidth employed.
Used only for local services such as VHF band stereo channels.
LSB – Lower Side Band / A form of SSB (Single Side Band).
Not intended for commercial use but is extensively used by Radio Amateurs on frequencies below 10
MHz. This assists in the separation of Commercial and Amateur users on traditionally shared bands and
prevents them from speaking to each other.
SSB is a very efficient method of transmission as the unwanted second sideband and carrier have
been removed. This allows the full transmitter power to be employed in carrying useful information
within the wanted sideband. As a result, greater distances are possible on SSB and a smaller
frequency bandwidth is required than with most other modes.
USB – Upper Side Band
The same comments apply as for LSB. By convention, Radio amateurs also use USB above 10 MHz.
CW - Continuous Wave
Also referred as Carrier Wave or Morse Code.
Commonly used on the short wave bands by radio amateurs toward the lower end of each band
allocation. Some commercial use is still made by shipping etc although its use is being phased out due to
the introduction of automated stations.
3-6-1 AUTO MODE SELECTION
When in auto mode, the receive mode is automatically set to digital auto mode and analog receive mode
is set to FM by the AR-DV1 microprocessor.
To activate auto mode or reconfirm its selection while in VFO mode, press the [MODE] key.
Then rotate the dial knob to select “AUTO” in the reverse contrast on the bottom of the LCD.
20
Note: Auto-mode is cancelled as soon as the receive mode is changed.
3-6-2 RECEIVE MODE SELECTION
Any receive mode may be selected at any frequency within the receiver’s frequency coverage.
To access the receive mode menu, press the [MODE] key.
The following modes are available:
AUTO, FM, AM, SAH, SAL, USB, LSB, CW, DSTR, YAES, DMR, D-CR, dPMR, P-25, ALINC.

DMR mode
Rotate the dial knob to select the desired receive mode.
Press the [ENT] key to confirm selection.
3-6-3 DIGITAL DATA DISPLAY
When DIG.DECODE setting in the option menu (refer to: Section 10-4) is set to ON, data information for
the received signal will be displayed on the bottom of the LCD.
21
3-7 CHANGING THE FREQUENCY STEP
The specification for channel occupancy, step (separation) and mode are decided by and allocated by the
Departments of Governments following international discussions.
The allocation of frequency bands are not the same all over the world and channel separation (step)
varies from band to band. As an example, the channel separation (step) for the MW (medium wave) band
in the U.S.A. is 10 kHz, and is 9 kHz in Europe and Japan.
For above reasons, it is necessary to change the frequency step size according to the local band plan.
The AR-DV1 has been pre-programmed at the factory with all the band plan data (specific to each market
area) so that the AR-DV1 will automatically select the appropriate step size and mode for the frequency
chosen. This greatly simplifies operation of the receiver while you are familiarizing yourself with all the
functions.
The pre-programming of step size may be manually overridden so you may choose alternative settings
at will or when band plans are updated.
If you wish to change the default tuning frequency step, press the [F] key and then the [2] key. The LCD will
display the current frequency step in reverse contrast. Rotate the dial knob to select the desired step.
To accept the displayed tuning step size, press the [ENT] key.
3-8 IF BANDWIDTH
The IF bandwidth selects how SELECTIVE the receiver will be when monitoring signals off air. However,
it is not simply a case of using the narrowest filter at all times; particular modes require differing amounts
of bandwidth in order to operate. Otherwise the receive system will not produce intelligible sound.
Correct receive mode and IF bandwidth must always be selected for optimum reception. If the bandwidth
selection is too narrow, distortion or signal break-up may occur. If the bandwidth selection is too wide,
adjacent interference may be encountered. For this reason, a selection of IF filter bandwidths are
provided as standard.
22
Typical examples of receive mode and IF bandwidth are:
200 kHz – VHF FM broadcast
30 kHz, 100 kHz – Wireless microphone, etc. (30 kHz for satellite FAX, too)
15 kHz – PMR, amateur band, etc. FM 6 kHz may also be used
6 kHz – VHF/UHF airband, short wave broadcast, medium & long wave, PMR, etc.
3 kHz – Short wave amateur band, short wave utility such as oceanic airband etc.
500 Hz – Morse code used by radio amateurs and some marine traffic on short wave
An appropriate IF filter is automatically selected when auto mode is selected. However any
combination of IF filter and receive mode is possible in the manual mode. When you have manually
selected an IF filter bandwidth, auto mode will be cancelled, but the receive mode, frequency step, etc
will be retained until they are changed manually.
3-8-1 MANUALLY SELECTING IF BANDWIDTH
Press the [F] key and then the [MODE] key.
Select a new bandwidth from the list by rotating the dial knob. To accept the new bandwidth selection,

6 MEMORY CHANNELS AND BANKS
It is convenient to store commonly used frequencies into a memory channel along with mode etc, as this
saves having to key the data in over and over again. Memory read is very straightforward and
quick when compared to retyping all data.
6-1 MEMORY CHANNEL OVERVIEW
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, so they
can be used over and over again. The AR-DV1 has 2,000 memory channels and one priority channel.
Each memory channel may hold:

One receive frequency

Receive mode

Tuning step

Text comment of up to 12 characters
The alphanumeric comment may be used to ease identification at a later date. The 2,000 memory
channels are divided into 40 banks, and each bank has 50 channels. The memory banks are identified
by the first BANK number 0, 1, 2, 3, …, 48, 49 and the individual channels are numbered from 00 to 49.
(Example): “1234” is the location: memory bank “12” and memory channel “34”
The data contents of memory and search banks are held in an EEPROM so that no backup battery is
required for memory retention.
The stored data may be quickly and easily recalled, changed or deleted using the memory recall and
delete functions.
Note: When the receiver is switched OFF, all VFO data will be
automatically stored into EEPROM memory storage.
33
6-2 STORING VFO FREQUENCIES AND DATA INTO MEMORY
The process to save a displayed VFO frequency to memory is as follows:
1. In VFO mode, select the required frequency, mode, etc.
2. Press and hold the [ENT] key for two seconds. The AR-DV1 will automatically find the next

Once frequency and mode data have been stored into a memory location, retrieval is quick and simple.
There are 40 banks (#00 ~ 39), 50 channels per bank with the AR-DV1.
(Sample of memory read screen)
1. If you already know the memory bank and memory channel, using the numeric keyad, enter the
memory bank number (two digits) and memory channel number (two digits). Then press the [ENT]
key.
(Above screen shows memory bank #05 and memory channel #00.)
2. The AR-DV1 will monitor whatever memory channel you enter into memory read.
3. While in memory read, changing the receive mode or frequency steps, etc. will automatically update the
memory contents.
4. If you don’t want to make changes, set memory protect to ON to avoid overwriding the contents.
5. To return to VFO mode, press the [VFO] key.
6-4 DELETE MEMORY CHANNEL

(Note: If the memory channel is write protected, it will not be deleted.)
35
7 SCAN – SCANNING MEMORY CHANNELS
The AR-DV1 has a scan mode whereby the contents stored in the memory channels are automatically
recalled and monitored very quickly for activity – scanned.
(Note: It is important that you do not confuse SCAN and SEARCH modes.)
SEARCH mode (covered later in this manual) automatically tunes the receiver through all frequencies
between two specified frequency limits looking for active frequencies.
7-1 SCAN – OUTLINE INTRODUCTION
During scan, the AR-DV1 automatically recalls memory channels which contain data in numeric order
and monitors looking for activity. When an ‘active’ memory channel is located (when a signal is found
and the squelch is open), the AR-DV1 will temporarily stop scanning.
7-2 STARTING SCAN
Presuming that some memory channels are programmed with data, start the scan process with one press
of the [SCAN] key. Once the scan process has been started, a bank number will be also be displayed
representing the current bank.
Ensure that the squelch is set to threshold point so that background noise is cancelled and the
squelch closes (otherwise scan will not operate).
When scan has been selected, only the currently displayed memory bank which contains data will be
scanned, and receive mode and frequency are not important. Any memory channels which contain no data
(empty) will be ignored and skipped.
7-3 SELECTING A SCAN BANK
The memory bank identifier (such as “03”) will be displayed on the middle of the LCD.
If more than one memory channel is programmed into the current memory bank, and when an ‘active’
channel has been located (busy, so the squelch opens), the scan process will temporarily pause on the
active channel. The memory location (such as “25”) will be displayed along with any accompanying text.
To select another memory bank for scanning, rotate the dial knob or enter the two digits of the memory
bank number from the numeric keypad.
36
To exit from scan mode, press the [VFO] key.
7-4 LOCKING OUT UNWANTED ACTIVE MEMORY CHANNELS (PASS)
It is possible to lock out (PASS) unwanted memory channels while in scan mode. This is useful to
eliminate unwanted permanent transmissions. It is important to understand the PASS function before
taking action or transmissions may be missed.
In memory read mode or while stopped on an unwanted frequency, press the [PASS] key.
Pressing the [PASS] key again on the same memory channel will de-select pass channel.
The scan process will resume. It will appear that all channels are still scanned, however, locked
out channels will be ‘skipped’, the scan will not stop on locked out channels.
7-5 SCAN GROUP
The AR-DV1 has 20 scan groups to be used with the bank link function and other functions.
The following parameters can be registered for each of the scan groups.

Bank link setting

Scan pause

Scan delay
To set up scan group, press the [F] key and then the [SCAN] key.
7-5-1 BANK LINK SETTING
1. There are 10 scan group and the group number can be selected between 0 ~ 9.
Rotate the dial knob to select the scan group. Then press the [▼] key to go to the bank select menu.
You can also use the numeric keypad to select the scan group.
To return to scan group selection menu, press the [▲] key.
37
2. Rotate the dial knob select the bank link group. Pressing the [PASS] key will toggle the link on and off.
3. Press the [ENT] key to complete setting or press the [CLR] key to abort entry.
7-5-2 SCAN DELAY
The scan delay parameter affects the time the AR-DV1 will remain on an active channel in the scan
mode once the received signal has disappeared and the squelch is closed. This is particularly useful
for customizing how long the receiver will wait for a reply before continuing to scan.
The parameter ranges are off, hold and 0.1 to 9.9 seconds in 0.1 second incremental.
(Default: 2.0 seconds)
To set the scan delay parameter, perform the following steps:
1. On the scan group setting screen, use the [▼] key or [▲] key to select [DELAY].
2. Rotate the dial knob to select the scan delay.
3. If “HOLD” is selected, the receiver will stop scanning
4. To confirm entry, press the [ENT] key. To set other parameters, press the [▼] key.
7-5-3 SCAN PAUSE
The scan pause parameter determines how long the receiver will remain on an active channel before
resuming scanning even if the channel is still busy. Scan pause helps keep you from having to manually
intervene to force the scan to continue or use channel lockout (pass).

11-4 PRIORITY FUNCTION
The priority function enables you to carry on scanning, searching or monitoring while the AR-DV1
58
checks a selected frequency for activity (taken from one of the 2,000 memory channels periodically).
The priority checking is accomplished by momentarily tuning the receive circuit to the priority frequency
to see if it is active. If the activity is found, the AR-DV1 will remain on the active frequency until
the signal disappears. If no activity is detected, the receiver returns to the VFO frequency, scan channel
or search bank from where it originated.
The priority function has a large number of applications and is particularly useful for keeping an eye on
a distress frequency while scanning or searching another frequency band.
Note: Depending upon the frequency and mode stored as priority, an audible click may be heard when
the priority function is in operation. This is quite normal and is caused by the internal switching of circuitry
necessary to accomplish the frequency change.
