Installation of Accessories
Antenna Installation
The supplied antenna provides good results over the entire frequency range of the
transceiver. However, for enhanced base station medium-wave and shortwave reception,
you may wish to connect an external (outside) antenna.
To install the supplied antenna
Hold the bottom end of the antenna, then screw it onto the mating connector on the
transceiver until it is snug. Do not over-tighten by use of extreme force.
Notes:
Never transmit without having an antenna connected.
When installing the supplied antenna, never hold the upper part of the antenna
while screwing it onto the mating connector on the transceiver.

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.4
If using an external antenna for transmission, ensure that the SWR presented to
the transceiver is 1.5:1 or lower.
Installation of FNB-82LI Battery Pack
The FNB-80LI is a high-performance Lithium-Ion battery providing high capacity in a
very compact package. Under normal use, the FNB-82LI may be used for approximately
300 charge cycles, after which operating time may be expected to decrease. If you have
an old battery pack which is displaying capacity which has become diminished, you
should replace the pack with a new one.
Referring to Figure 1, slide the Battery Cover toward the bottom to remove it while
slide the Battery Cover Latch.
Referring to Figure 2, install the FNB-82LI into the Battery Nest.
Replace the Battery Cover, as shown in Figure 3.
If the battery has never been used, or its charge is depleted, it may be charged by
connecting the NC-85 Battery Charger, as shown in the illustration, to the EXT DC jack.
If only 12 ~ 16 Volt DC power is available, the optional E-DC-21 DC Adapter (with its
cigarette lighter plug) may also be used for charging the battery.
While the battery is being charged, display will indicate “CHGING” and the TX/BUSY
indicator will glow red.
When charging is finished, display will change to indicate “CHGFUL” and the TX/BUSY
indicator will change to glow green.
Interface of Packet TNCs
The VX-2R may be used for Packet operation, using the optional CT-91 microphone
adapter (available from your Yaesu dealer) for easy interconnection to commonly-
available connectors wired to your TNC. You may also build your own cable using a
four-conductor miniature phone plug, per the diagram below.
The audio level from the receiver to the TNC may be adjusted by using the VOLUME
knob, as with voice operation. The input level to the VX-2R from the TNC should be
adjusted at the TNC side; the optimum input voltage is approximately 5 mV at 2000
Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, so as to
prevent voltage spikes from possibly damaging your transceiver.

Operation
R. F. says: Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many
features of the VX-2R. I know you’re anxious to get on the air, but I encourage you to
read the “Operation” section of this manual as thoroughly as possible, so you’ll get the
most out of this fantastic new transceiver. Now. . .let’s get operating!
Switching Power On and Off
1. Be sure the Battery Pack is installed, and that the battery is fully charged. Connect
the antenna to the top panel ANTENNA jack.
2. Press and hold in the POWER switch (on the left side of the transceiver) for one
second. Two beeps will be heard when the switch has been held long enough, and
the current DC supply voltage will indicate on the display for 2 second. After this
interval, the display will resume its normal indication of the operating frequency.
3. To turn the VX-2R off, press and hold in the POWER switch again for one second.
R.F. says: If you don’t hear the two “Beep” tones when the radio comes on, the Beeper
may have been disabled via the Menu system. See page ??, which tells you how to
reactivate the Beeper.
Adjusting the Volume Level
Rotate the VOLUME control (inner knob) to set the desired audio level. Clockwise
rotation increases the volume level.
Squelch Adjustment
The VX-2R’s Squelch system allows you to mute the background noise when no signal is
being received. Not only does the Squelch system make “standby” operation more
pleasant, it also significantly reduces battery current consumption.
The Squelch system may be adjusted independently for the FM and Wide-FM (FM
Broadcast) modes.
1. Press and hold the [H/L(STEP)SET] key for one second to enter the Set Mode.
2. Rotate the DIAL knob to select the Set Mode Item 1: SQL.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to set the background noise is just silenced (typically at a
setting of about “1” or “2” for FM, and “2” or “3” for Wide-FM); this is point of
maximum sensitivity to weak signals.

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.6
5. When you are satisfied with the Squelch threshold setting, press the PTT key
momentarily to save the new setting and exit to normal operation.
R.F. Says: 1) A special “RF Squelch” feature is provided on the VX-2R. This feature
allows you to set the squelch so that only signals exceeding a certain S-meter level will
open the squelch. See page ?? for details.
2) If you’re operating in an area of high RF pollution, you may need to consider “Tone
Squelch” operation using the built-in CTCSS Decoder. This feature will keep your radio
quiet until a call is received from a station sending a carrier which contains a matching
(subaudible) CTCSS tone. Or if your friends have radios equipped with DCS (Digital
Coded Squelch) like your VX-2R has, try using that mode for silent monitoring of busy
channels.
Selecting the Operating Band
The VX-2R covers an incredibly wide frequency range, over which a number of different
operating modes are used. Therefore, the VX-2R’s frequency coverage has been divided
into different operating bands, each of which has its own pre-set channel steps and
operating modes. You can change the channel steps and operating modes later, if you
like (see page ??).
To Change Operating Bands:
1. Press the [BAND] key repetitively. You will see the LCD indication move toward a
higher frequency band each time you press the [BAND] key.
2. If you wish to move the operating band selection downward (toward lower
frequencies), press the [F/W] key first, then press the [BAND] key.
3. Once you have selected the desired band, you may initiate manual tuning (or
scanning) per the discussions on the next chapter.
Frequency Navigation
The VX-2R will initially be operating in the “VFO” mode, a channelized system which
allows free tuning throughout the currently-selected operating band.
Two basic frequency navigation methods are available on the VX-2R:
1) Tuning Dial (Outer ring of dual control on Top Panel)
Rotation of the DIAL allows tuning in the pre-programmed steps established for the
current operating band. Clockwise rotation of the DIAL causes the VX-2R to be tuned
toward a higher frequency, while counter-clockwise rotation will lower the operating

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.7
frequency.
If you press the [F/W] key momentarily, then rotate the DIAL, frequency steps of 1 MHz
will be selected. This feature is extremely useful for making rapid frequency excursions
over the wide tuning range of the VX-2R.
2) Scanning
From the VFO mode, press and hold the [BAND] key. The VX-2R will begin scanning
toward a higher frequency, and will stop when it receives a signal strong enough to
break through the Squelch threshold. The VX-2R will then hold on that frequency
according to the setting of the “RESUME” mode (Set Mode Item 28: RESUME). See
page ?? for details.
If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of
a higher frequency), just rotate the DIAL one click in the counter-clockwise direction
while the VX-2R is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL one click clockwise.
Press the PTT switch momentarily to cancel the scanning.
Transmission
Once you have set up an appropriate frequency inside one of the 144 MHz or 430 MHz
Amateur bands on which the VX-2R can transmit, you’re ready to transmit. These are
the most basic steps; more advanced aspects of transmitter operation will be discussed
later.
1. To transmit, press the PTT switch, and speak into the front panel microphone
(located in the upper left-hand corner of the speaker grille) in a normal voice level.
The TX/BUSY indicator will glow red during transmission.
2. To return to the receive mode, release the PTT switch.
3. During transmission, the relative power level will be indicated on the LCD.
Additionally, the “L” icon will appear at the bottom of the display while operating
on the “Low Power” Level setting.
R.F. Says: If you’re just talking to friends in the immediate area, you’ll get much longer
battery life by switching to Low Power operation. To do this, press the [H/L] key so that
the “L” icon appears at the bottom of the display. And don’t forget: always have an
antenna connected when you transmit.
Transmission is possible only on the 144 MHz and 430 MHz bands.
R.F. Says: 1) The VX-2R is smart! You can set up Low power on 144 MHz band, while

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.8
leaving 430 MHz on High power, and the radio will remember the different settings on
both band. And when you store memories, you can store High and Low power settings
separately in each memory, so you don’t waste battery power when using very close-in
repeaters!
2) When you are operating on one of the Low power settings, you can press the [F/W]
key, when press the PTT switch, to cause the VX-2R to transmit (temporarily) on High
power. After one transmission, the power level will revert to the previously-selected Low
power setting.
Keyboard Locking
In order to prevent accidental frequency change or inadvertent transmission, various
aspects of the VX-2R’s keys and switches may be locked out. The possible lockout
combinations are:
KEY: Just the front panel keys are locked out
DIAL: Just the top panel DIAL is locked out
K + D: Both the DIAL and Keys are locked out
PTT: The PTT switch is locked (TX not possible)
K + P: Both the keys and PTT switch are locked out
D + P: Both the DIAL and PTT switch are locked out
ALL: All of the above are locked out
To lock out some or all of the keys:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 9: LOCK.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to choose between one of the locking schemes as outlined
above.
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
To activate the locking feature, press the [F/W] key, then press and hold the [BAND]
key for one second. The “Key Lock” icon will appear on the LCD. To cancel locking, again
above procedures.
Keypad/LCD Illumination
Your VX-2R includes a reddish illumination lamp which aids in nighttime operation.

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.9
The red illumination yields clear viewing of the display in a dark environment, with
minimal degradation of your night vision. Three options for activating the lamp are
provided:
KEY Mode: Illuminates the Keypad/LCD for five seconds when any key pressed.
CONT Mode: Illuminates the Keypad/LCD continuously.

5. When you have made your choice, press the PTT key to save the new setting and
return to normal operation.
R.F. Says: You may adjust the Keypad/LCD illumination level and LCD contrast by the
Set Mode. See page ?? for details.
Disabling the Keypad Beeper
If the keypad’s Beeper creates an inconvenience (particularly when operating in a quiet
room), it may easily be disabled.
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 8: BEEP.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to change the setting from ON to OFF.
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
6. If you wish to re-enable the Beeper, just repeat the above procedure, rotate the
DIAL knob to select ON in step “4” above.
Advanced Operation
Now that you’re mastered the basics of VX-2R operation, let’s learn more about some of
the really neat features.
Changing the Channel Steps
The VX-2R’s synthesizer provides the option of utilizing channel steps of

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.10
5/9/10/12.5/15/20/25/50/100 kHz per step, any number of which may be important to
your operating requirements. The VX-2R is set up at the factory with different default
steps on each operating band which probably are satisfactory for most operation.
However, if you need to change the channel step increments, the procedure to do so is
very easy.
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 3: STEP.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to select the new channel step size.
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
R.F. Says: 9 kHz step is available on the BC band only.
Changing the Operating Mode
The VX-2R provides for automatic mode changing when the radio is tuned to different
operating frequencies. However, should an unusual operating situation arise in which
you need to change between the available operating modes (FM-Narrow, FM-Wide, and
AM), here is the procedure for doing so:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 4: RX MD.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to select the new operating mode. The available selections
are:
AUTO: Automatic mode setting per default values for the selected frequency range.
N-FM: Narrow-bandwidth FM (used for voice communication)
W-FM: Wide-bandwidth FM (used for high-fidelity broadcasting)
AM: Amplitude Modulation
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
R.F. Says: Unless you have a compelling reason to do so, leave the Automatic Mode
Selection feature on so as to save time and trouble when changing bands. If you make a
mode change for a particular channel or station, you can always store that one channel
into memory, as the mode setting will be memorized along with the frequency
information.

Repeater Operation
Repeater stations, usually located on mountaintops or other high locations, provide a
dramatic extension of the communication range for low-powered hand-held or mobile
transceivers. The VX-2R includes a number of features which make repeater operation
simple and enjoyable.
Repeater Shifts
Your VX-2R has been configured, at the factory, for the repeater shifts customary in
your country. For the 144 MHz band shift will be 600 kHz; on the 430 MHz band, the
shift may be 1.6 MHz, 7.6 MHz, or 5 MHz (USA version).
Depending on the part of the band in which you are operating, the repeater shift may be
either downward (–) or upward (+), and one of these icons will appear at the bottom of
the LCD when repeater shifts have been enabled.
Automatic Repeater Shift (ARS)
The VX-2R provides a convenient Automatic Repeater Shift feature, which causes the
appropriate repeater shift to be automatically applied whenever you tune into the
designated repeater sub-bands in your country. These sub-bands are shown below.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 5: ARS.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to select “ON” (to enable Automatic Repeater Shift).
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
Manual Repeater Shift Activation
If the ARS feature has been disabled, or if you need to set a repeater shift direction
other than that established by the ARS, you may set the direction of the repeater shift
manually.
To do this:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 7: RPT.

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.12
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to select the desired shift among “–RPT,” “+RPT,” and
“SIMP.”
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
Changing the Default Repeater Shifts
If you travel to a different region, you may need to change the default repeater shift so
as to ensure compatibility with local operating requirements.
To do this, follow the procedure below:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 6: SHIFT.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to select the new repeater shift magnitude.
5. When you have made your selection, press the PTT key to save the new setting and
return to normal operation.
R.F. Says: If you just have one “odd” split that you need to program, don’t change the
“default” repeated shifts using this Menu Item! Enter the transmit and receive
frequencies separately, as shown on page ??.
Checking the Repeater Uplink (Input) Frequency
It often is helpful to be able to check the uplink (input) frequency of a repeater, to see if
the calling station is within direct (“Simplex”) range.
To do this, just press the [HM/RV] key. You’ll notice that the display has shifted to the
repeater uplink frequency. Press the [HM/RV] key again to cause operation to revert to
normal monitoring of the repeater downlink (output) frequency.
RF Says: The configuration of this key may be set either to “RV” (for checking the input
frequency of a repeater, or “HM” (for instant switching to the “Home” channel for the
band you are operating on). To change the configuration of this key, use Set Mode Item
40: HM/RV. See page ??.
CTCSS Operation
Many repeater systems require that a very-low-frequency audio tone be superimposed
on your FM carrier in order to activate the repeater. This helps prevent false activation
of the repeater by radar or spurious signals from other transmitters. This tone system,

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.13
called “CTCSS” (Continuous Tone Coded Squelch System), is included in your VX-2R,
and is very easy to activate.
R.F. Says: CTCSS setup involves two actions: setting the Tone Frequency and then
setting of the Tone Mode. These actions are set up by using the [MD] key or Set Mode
Items 18: SQL TYP and 19: TN FRQ.
1. Press and hold the [MD] key for one second. This provides a “Short-cut” to Set Mode
Item 18: SQL TYP.
2. Press the [H/L] key momentarily to enable adjustment this Item.
3. Rotate the DIAL knob so that “TONE” appears on the display; this activates the
CTCSS Encoder, which allows repeater access.
R.F. Says: You may notice an additional “DCS” icon appearing while you rotate the
DIAL knob in this step. We’ll discuss the Digital Code Squelch system shortly.
4. Rotate the DIAL knob in step “3” above will occasionally appear the “TSQ.” When
“TSQ” appears, this means that the Tone SQueLch system is active, which mutes
your VX-2R’s receiver until it receives a call from another radio sending out a
matching CTCSS tone. This can help keep your radio quiet until a specific call is
received, which may be helpful while operating in congested areas.
5. When you have made your selection of the CTCSS tone mode, press the [H/L] key
momentarily, then rotate the DIAL one click clockwise to select Set Mode Item 19:
TN FRQ. This Menu selection allows setting of the CTCSS tone frequency to be
used.
6. Press the [H/L] key momentarily to enable the adjustment of the CTCSS frequency.
7. Rotate the DIAL knob until the display indicates the Tone Frequency you need to be
using (ask the repeater owner/operator if you don’t know the tone frequency).
8. When you have made your selection, press the [H/L] key momentarily, then press
the PTT switch to save the new settings and exit to normal operation.
R.F. Says: Your repeater may or may not re-transmit a CTCSS tone - some systems just
use CTCSS to control access to the repeater, but don’t pass it along when transmitting.
If the S-Meter deflects, but the VX-2R is not passing audio, repeat steps “1” through “4”
above, but rotate the DIAL so that “TSQ” disappears - this will allow you to hear all
traffic on the channel being received.
DCS Operation
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does CTCSS. The DCS Encoder/Decoder is built into your VX-2R, and operation is very

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.14
similar to that just described for CTCSS. Your repeater system may be configured for
DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use
transceivers equipped with this advanced feature.
R.F. Says: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS
and that you select a tone code.
1. Press and hold the [MD] key for one second. This provides a “Short-cut” to Set Mode
Item 18: SQL TY
2. Press the [H/L] key momentarily to enable adjustment this Item.
3. Rotate the DIAL knob until “DCS” appears on the display; this activates the DCS
Encoder/Decoder.
4. Press the [H/L] key momentarily, then rotate the DIAL to select Set Mode Item 20:
DCS CD).
5. Press the [H/L] key momentarily to enable the adjustment of the DCS code.
6. Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask
the repeater owner/operator if you don’t know DCS Code; if you are working
simplex, just set up the DCS Code to be the same as that used by your friend(s).
7. When you have made your selection, press the [H/L] key momentarily,, then press
the PTT switch to save the new settings and exit to normal operation.
R.F. Says: Remember that the DCS is an Encode/Decode system, so your receiver will
remain muted until a matching DCS code is received on an incoming transmission.
Switch the DCS off when you’re just tuning around the band!
Tone Search Scanning
In operating situations where you don’t know the CTCSS or DCS tone being used by
another station or stations, you can command the radio to listen to the incoming signal
and scan in search of the tone being used. Two things must be remembered in this
regard:
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous
discussion). In the case of CTCSS, “TSQ” will appear on the display; in the case of

FCC ID: K66VX-2R
VX-2R OPERATING MANUAL
Vertex Standard Co., Ltd.15
DCS, “DCS” will appear on the display.
2. Press and hold the [H/L] key for one second to enter the Set mode.
3. Rotate the DIAL knob to select the Set Mode Item 19: TN FRQ when TONE SQL is
selected, or Set Mode Item 20 DCS CD during DCS operation.
4. Press the [H/L] key momentarily to enable adjustment of the selected Menu Item.
5. Press and hold the [BAND] key for one second to start scanning for the incoming
CTCSS or DCS tone/code.
6. When the radio detects the correct tone or code, it will halt on that tone/code, and
audio will be allowed to pass. Press the [BAND] key to lock in that tone/code, then
press PTT to exit to normal operation.
R.F. Says: If the Tone Scan feature does not detect a tone or code, it will continue to scan
indefinitely. When this happens, it may be that the other station is not sending any tone.
You can press the PTT switch to halt the scan at any time.
You also can press the MONI key during Tone Scanning to listen to the (muted) signal
from the other station. When you release the MONI key, Tone Scanning will resume
after about a second.
Tone Scanning works either in the VFO or Memory modes.
CTCSS/DCS Bell Operation
During CTCSS Decode or DCS operation, you may set up the VX-2R such that a ringing
“bell” sound alerts you to the fact that a call is coming in. Here is the procedure for
activating the CTCSS/DCS Bell:
1. Set the transceiver up for CTCSS Decode (“Tone Squelch”) or DCS operation, as
described previously.
2. Adjust the operating frequency to the desired channel.

Tone Calling (1750 Hz)
If the repeaters in your country require a 1750-Hz burst tone for access (typically in
Europe), you can set the MONI key to serve as a “Tone Call” switch instead. To change
the configuration of this switch, we again use the Menu to help us.

To access a repeater, press and hold in the MONI key for the amount of time specified by
the repeater owner/operator. The transmitter will automatically be activated, and a
1750-Hz audio tone will be superimposed on the carrier. Once access to the repeater has
been gained, you may release the MONI key, and use the PTT key for activating the
transmitter.
ARTS (Automatic Range Transponder System)
The ARTS feature uses DCS signaling to inform both parties when you and another

VX-2R OPERATING MANUAL

ARTS-equipped station are within communications range. This may be particularly
useful during Search-and Rescue situations, where is important to stay in contact with
other members of your group.
Both stations must set up their DCS codes to the same code number, then activate their
ARTS feature using the command appropriate for their radio. Alert ringers may be
activated, if desired.
Whenever you push the PTT, or every 25 (or 15) seconds after ARTS is activated, your
radio will transmit a signal which includes a (subaudible) DCS signal for about 1 second.
If the other radio is in range, the beeper will sound (if enabled) and the display will
show “IN RNG” as opposed to the out of range display “OUT RNG” in which ARTS
operation begins.
Whether you talk or not, the polling every 15 or 25 seconds will continue until you de-
activate ARTS. Every 10 minutes, moreover, you can have your radio transmit your
callsign via CW, so as to comply with identification requirements. When ARTS is de-
activated, DCS will also be deactivated (if you were not using it previously in non-ARTS
operation).
If you move out of range for more than one minute (four pollings), your radio will sense
that no signal has been received, three beeps will sound, and the display will revert to
“OUT RNG.” If you move back into range, your radio will again beep, and the display
will change back to the “IN RNG” indication.
During ARTS operation, your operating frequency will continue to be displayed, but no
changes may be made to it or other settings; you must terminate ARTS in order to
resume normal operation. This is a safety feature designed to prevent accidental loss of
contact due to channel change, etc.
Basic ARTS Setup and Operation
1. Set your radio and the other radio(s) to the same DCS code number, per the
discussion on page ??.
2. Press and hold the [%] key for one second. You will observe the “OUT RNG” display
on the LCD below the operating frequency. ARTS operation has now commenced.
3. Every 25 seconds, your radio will transmit a “polling” call to the other station.
When that station responds with its own ARTS polling signal, the display will
change to “IN RNG” to confirm that the other station’s polling code was received in
response to yours.
4. Press and hold the [%] key for one second to exit ARTS operation and resume
normal functioning of the transceiver.

R.F. Says: ARTS won’t work if you have used the Lock feature to disable the PTT!
ARTS Polling Time Options
The ARTS feature may be programmed to poll every 25 seconds (default value) or 15
seconds. The default value provides maximum battery conservation, because the polling
signal is sent out less frequently. To change the polling interval:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 38: AR INT.
3. Press the [H/L] key momentarily to enable adjustment of the selected Menu Item.
4. Rotate the DIAL knob to select the desired polling interval (15 or 25 seconds).
5. When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
ARTS Alert Beep Options
The ARTS feature allows two kinds of alert beeps (with the additional option of turning
them off), so as to alert you to the current status of ARTS operation. Depending on your
location and the potential annoyance associated with frequent beeps, you may choose
the Beep mode which best suits your needs. The choices are:
IN RNG: The beeps are issued only when the radio first confirms that you are within
range, but does not re-confirm with beeps thereafter.
ALWAYS: Every time a polling transmission is received from the other station, the alert
beeps will be heard.
OFF: No alert beeps will be heard; you must look at the display to confirm current
ARTS status.
To set the ARTS Beep mode, use the following procedure:
1. Press and hold the [H/L] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 37: ARTSBP.
3. Press the [H/L] key momentarily to enable adjustment of the selected Menu Item.
4. Rotate the DIAL knob to select the desired ARTS Beep mode (see above).
5. When you have made your selection, press the PTT key to save the new setting and
exit to normal operation.
CW Identifier Setup
The ARTS feature includes a CW identifier, as discussed previously. Every ten minutes
during ARTS operation, the radio can be instructed to send “DE (your callsign) K” if this

6. Rotate the DIAL knob to select the first letter/number of your callsign, then press
the [V/M] key momentarily to save the first letter/number and move on to the next
character.
7. Repeat the previous step as necessary to complete your callsign. Note that the
“slant bar” (– • • – •) is among the available characters, should you be a “portable”
station.
8. If you mistake, press the [BAND] key to back-space the cursor, re-enter the correct
letter/number.
9. Press the [HM/RV] key to delete all data after the cursor that may have been
previously stored erroneously.
10. When you have entered your entire callsign, press the [H/L] key momentarily to
confirm the callsign, then press the PTT key to save the settings and exit to normal
operation.
R.F. Says: You may check your work by monitoring the entered callsign. To do this,
repeat steps 1- 3 above, then press the [MON/F] key.
DTMF Operation
Despite the lack of a DTMF keypad, you can still transmit DTMF tones with the VX-2R
for repeater control or autopatch use.
Manual DTMF Tone Generation
DTMF Autodialer
Nine DTMF Autodial memories are provided, allowing you to store telephone numbers
for autopatch use. You can also store short autopatch or Internet-link access code
