EXT DC Jack
When an external 12-Volt DC power source is available, you may connect the (optional)
E-DC-5B DC Cable w/Noise Filter or E-DC-6 DC Cable here.
Do not connect any wire to this jack if that wire is connected directly to a 28-Volt DC
source. Connecting the VXA-710 directly to a source which exceeds 15.0 Volts DC will
result in damage to the unit.
Before You Begin
Precautions
€ This apparatus is capable of two-way communication on channels used for critical
aviation safety communications. Therefore, it is important that this radio be kept away
from children or other unauthorized users at all times.
€ When making DC connections via the (optional) E-DC-5B DC cable, be absolutely
certain to observe the proper voltage level and polarity guidelines. Do not connect this
radio directly to any 24 ~ 28 Volt DC source, nor to AC power of any kind. Connecting
the VXA-710 directly to a source which exceeds 15.0 Volts DC will result in damage to
the unit.
€ Do not dispose of the LI-ion Battery Pack in a fire. Do not carry a LI-ion Battery Pack in
your pocket, where keys or coins could short the terminals. This could create a serious
fire/burn danger, and possibly cause damage to the LI-ion pack.
How to Install the Quick Draw Belt Clip
ˆ Connect the hanger to the rear of the VXA-710, with the notch pointing directly up, using
the supplied screw (Figure 1). Use only the screw included with the clip to mount the clip
to the back of the VXA-710!
ˆ Clip the Quick-Draw Belt Clip onto your belt (Figure 2).
ˆ To install the VXA-710 into the Quick-Draw Belt Clip, align the hanger with the QuickDraw Belt Clip, and slide the VXA-710 into its slot until a click is heard (Figure 3).
ˆ To remove the VXA-710 from the Quick-Draw Belt Clip, rotate the VXA-710 180 degrees,
then slide the VXA-710 out from the Quick-Draw Belt Clip (Figure 4).
Installation of FNB-80LI 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-80LI may be used for approximately 300
Vertex Standard Co., Ltd.
FCC ID: K6610623X20
IC ID: 511B-10623X20
Operating Manual
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.
ˆ Install the FNB-80LI as shown in the illustration.
ˆ Close the Battery Pack Latch on the bottom of the radio.
Do not attempt to open any of the rechargeable LI-ion packs, as personal injury or damage
to the LI-ion pack could occur if a cell or cells become accidentally short-circuited.
Battery Charging
If the battery has never been used, or its charge is depleted, it may be charged by
connecting the NC-72B/C 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-5B DC Cable (w/cigarette
lighter plug) or E-DC-6 DC Cable may also be used for charging the battery, as shown in the
illustration. The “Now Charging . . .” will blink in the display while the battery is being
charged. When charging is finished (approximately five hours), the display will change to
indicate “Complete” and the BUSY/TX indicator will blink blue.
Important Notes:
€ Do not leave the charger connected to the transceiver for continuous periods in excess
of 24 hours. Long term overcharging can degrade the LI-ion battery pack and
significantly shorten its useful life.
€ If using a charger other than the NC-72B/C, or if using a battery pack other than the
FNB-80LI, follow the appropriate instructions provided with the charger/battery. Contact
your Dealer if you have any doubts about the appropriateness of the particular charger
or battery pack you intend to use.
Installation of FBA-23 Alkaline Battery Case (Option)
The optional FBA-23 Battery Case allows receive monitoring using two “AA” size Alkaline
batteries.
To Install Alkaline Batteries into the FBA-23
ˆ Slide the batteries into the FBA-23 as shown in the illustration, with the Negative (–) side
of the batteries touching the spring connections inside the FBA-23.
ˆ Open the Battery Pack Latch on the bottom of the radio.
ˆ Install the FBA-23 into the battery compartment on the back of the transceiver, then
close the Battery Pack Latch on the bottom of the radio.
The FBA-23 does not provide connections for charging, since Alkaline cells cannot be recharged. Therefore, the NC-72B/C, E-DC-5B, or E-DC-6 may safely be connected to the
EXT DC jack when the FBA-23 is installed.
Vertex Standard Co., Ltd.
FCC ID: K6610623X20
IC ID: 511B-10623X20
Operating Manual
Notes:
€ The FBA-23 is designed for use only with AA-type Alkaline cells.
€ If you do not use the VXA-710 for a long time, remove the Alkaline batteries from the
FBA-23, as battery leakage could cause damage to the FBA-23 and/or the transceiver.
Low Battery Indication
€ As your battery discharges during use, the voltage will gradually become lower. When
the “BATTERY” icon will blink on the LCD display, the battery pack must be recharged
before further use.
€ Avoid recharging Li-Ion batteries before the “Low Battery” indicator is observed, as this
can degrade the charge capacity of your Li-Ion battery pack. Vertex Standard
recommends that you carry an extra, fully-charged pack with you so you will not lose
communications capability due to a depleted Li-Ion battery.
This “deep cycling” practice will help to maintain longer overall battery life after many
recharging cycles.
AC Operation Using NC-72B/C (Receiving only)
The VXA-710 may be operated from your house current by use of the supplied NC-72B/C
Battery Charger. The NC-72B/C should only be used for reception, because it is not capable
of supplying sufficient current to support transmission.
To use the NC-72B/C, turn the transceiver off, then plug the miniature connector of the
Battery Charger into the EXT DC jack on the side of the radio. Now plug the Battery Charger
into the wall outlet. You may now turn on the transceiver.

Scanning Operation
Basic Scan
The VXA-710 allows you to scan automatically in the VFO*1, Main Memory, “Book” Memory,
Weather Channel*2, or BRS channel modes. It pauses on signals encountered, so you can
talk to the station(s) on that frequency, if you like.
*1: In the VFO mode, the automatic scanner is only available in the current operating band
(AIR band or FM BC band). Furthermore, on the AIR band, the automatic scanner is only
available in the COM band (118.000 - 136.975 MHz); when the scanner reaches the
uppermost frequency in the COM band, it will revert to the bottom end of the COM band and
repeat the scanning process until you cancel the scanning process.
*2: USA version only.
If you wish to scan in the NAV band (108.000 - 117.975 MHz), you can do so manually, as
described below.
Scanning operation is basically the same in each of the above modes.
ˆ Press the [SCAN(DW)MT] key momentarily to start the automatic scanner upward
(toward a higher frequency or a higher channel number).
ˆ When the scanner encounters a signal, scanning pauses and the radio remains on that
16

channel until one second after the signal disappears, after which scanning will resume.
ˆ While the scanner remains paused on a frequency, the decimal point of the frequency
display blinks. The display will be illuminated unless the Scan Lamp Feature is turned
off.
ˆ To change the scan direction, turn the DIAL selector knob one click in the opposite
direction.
ˆ To stop the automatic scanner, press the PTT switch or the [SCAN(DW)MT] key
momentarily.
The VXA-710’s automatic scanner is not operational in the NAV band (108.000 - 117.975
MHz), because the NAV stations (ILS, etc.) transmit constantly (thereby causing the scanner
to stop repeatedly). However, you can scan manually in the NAV band, per the following
procedure:
ˆ Press and hold the [SCAN(DW)MT] key to start the manual scanner. Scanning will
continue as long as the key is depressed.
ˆ Release the [SCAN(DW)MT] key to stop the manual scanner immediately.
Note: When scanning upward in frequency, when the frequency reaches the COM Band
(118.000 - 136.975 MHz) via manual scanning, the VXA-710 will switch to the automatic
scanner mode.
Channel-Skip Scanning
Continuous-carrier stations like ATIS (Automatic Terminal Information Service) or Weather
Broadcast stations inhibit scanner operation. Since these stations are always active, the
scanner will be halted repeatedly on their channels. Such channels can be set to be
“skipped” during Memory scanning (MR, Book, WX, or BRS modes), if you like, so as not to
interfere with automatic channel scanning:
ˆ Recall the Memory Channel to be skipped during scanning.
ˆ Press and hold the [9(SKIP)] key for 2 seconds. The “
icon will appear at the left of the
frequency display, indicating that the channel is to be ignored during scanning.
ˆ Later, to re-enable the memory channel for scanning, repeat the first two steps. The “
icon will disappear by the channel you have just re-enabled.
Note: A memory set to be “skipped” is still accessible for manual memory selection using
the DIAL selector knob.
Programmable (Band Limit) Memory Scan (PMS)
This feature allows you to set sub-band limits for either scanning or manual VFO operation.
For example, you might with to set up a limit of COM band (118.000 MHz to 136.975 MHz.

just-programmed range.
Note: The PMS feature does not activated on the WX and BRS frequencies.
Dual Watch Operation
The Dual Watch feature automatically checks for activity on a “Priority” channel* while you
are operating on another channel. During Dual Watch operation, the current channel and the
Priority channel will each be polled for a 500 ms interval, as the VXA-710 looks for activity
on each channel.
ˆ To start Dual Watch, press the [F] key followed by [SCAN(DW)MT] key.
ˆ The “DW” icon will appear on the display.
ˆ While receiving on the “current” channel (not the Priority channel), you may push the
PTT switch at any time to transmit on that channel.
ˆ When a signal is received on the Priority channel, operation immediately shifts to the
Priority channel; the “DW” icon will blink, and the display will become illuminated.
ˆ While receiving on the priority channel, if you momentarily press the PTT switch, Dual
Watch will be disabled. You may then transmit on the Priority Channel.
ˆ To stop Dual Watch, press the [F] key followed by [SCAN(DW)MT] key.
ˆ If you wish, you may use both the Dual Watch and Scan features simultaneously. To do
this, start the Dual Watch first, then start the Scanner.

Operating Manual
CTCSS Operation
The CTCSS operation allows to silently monitor for calls on busy channels and to transmit
CTCSS tone. The decode function monitors receiver audio through a narrow filter at the
same subaudible frequency, keeping the squelch closed until a matching tone is received,
while the transmit (encode) function superimpose a subaudible tone (at a frequency too low
to be heard) on the transmit carrier.
The CTCSS setup involves two actions: setting the Tone Mode and then setting of the Tone
Frequency. These actions are set up by using the [1(VOR)TN] and [2(TO)CD] keys, or Menu
Items (SQL Type) and (TONE Set).
ˆ Press and hold the [1(VOR)TN] key for 3 seconds. This instantly recalls Menu Item
(SQL Type).
ˆ Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
ˆ Rotate the DIAL selector knob so that “T” appears at the bottom right corner on the
display; this activates the CTCSS Encoder, which allows transmit a CTCSS tone only.
Note: You may notice an additional “DCS” icon appearing while you rotate the DIAL
selector knob in this step. We’ll discuss the Digital Code Squelch system shortly.
ˆ Rotating the DIAL selector knob in above step will occasionally cause “TSQ” to appear.
When “TSQ” appears, this means that the Tone SQuelch system is active, which mutes
your VXA-710’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.
ˆ When you have made your selection of the CTCSS tone mode, press the [SEL(SET)]
key momentarily, then rotate the DIAL selector knob one click clockwise to select Menu
Item (TONE Set). This Menu selection allows setting of the CTCSS tone frequency to be
used.
ˆ Press the [SEL(SET)] key to enable the adjustment of the CTCSS frequency.
ˆ Rotate the DIAL selector knob until the display indicates the Tone Frequency you need
to be using.
ˆ When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exits to normal operation.
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 VXA-710, and operation is very similar
to that just described for CTCSS.
Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and

that you select a Tone Code.
ˆ Press and hold the [1(VOR)TN] key for 2 seconds. This instantly recalls Menu Item
(SQL Type).
ˆ Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
ˆ Rotate the DIAL selector knob until “DCS” appears on the display; this activates the
DCS Encoder/Decoder.
ˆ Press the [SEL(SET)] key momentarily, then rotate the DIAL selector knob two clicks
clockwise to select Menu Item (DCS Set).
ˆ Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
ˆ Rotate the DIAL selector knob until the desired DCS Code (a three-digit number). Just
set up the DCS Code to be the same as that used by your group.
ˆ When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exits to normal operation.
Note: 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!
CTCSS/DCS Bell Operation
During CTCSS Decode or DCS operation, you may set the VXA-710 up 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:
ˆ Set the transceiver up for CTCSS Decode (“Tone Squelch”) or DCS operation, as
described previously.
ˆ Press the [F] key followed by [SEL(SET)] key to activate the Menu (“SET”) mode.
ˆ Rotate the DIAL selector knob to select Menu Item “2. Sound,” then press the
[SEL(SET)] key.
ˆ Rotate the DIAL selector knob to select Sub Menu Item “2. Bell,” then press the
[SEL(SET)] key.
ˆ Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
ˆ Rotate the DIAL selector knob to select “ON” (to enable the CTCSS/DCS Bell).
ˆ Press the [SEL(SET)] key to save the new setting, then press the PTT key repetitively
until the radio exits to normal operation.
When the CTCSS/DCS Bell feature is enabled, the “BELL” icon appears at the bottom
center of the display. When a station calls you whose transceiver is sending a CTCSS tone
or DCS code which matches that set into your decoder, the “BELL” icon will blinks, flashes
the BUSY/TX indicator in sequential colors, and a ringer sounds to get your attention.

Miscellaneous Setting
Changing the Channel Step
The VXA-710’s FM BC Band provides the option of utilizing channel steps of
5/10/12.5/15/20/25/50/100 kHz per step (factory default: 100 kHz). If you need to change the
channel step, the procedure to do so is very easy.

then press the PTT key repetitively until the radio exit to normal operation.
Automatic Power-Off (APO) Feature
The APO feature helps conserve battery life by automatically turning the radio off after a
user-defined period of time within which there has been no dial or key activity. The available
selections for the time before power-off are 0.5/1/8 hours, as well as APO Off.
The default condition for the APO is OFF, and here is the procedure for activating it:
ˆ Press the [F] key followed by [SEL(SET)] key to activate the Menu (“SET”) mode.
ˆ Rotate the DIAL selector knob to select Menu Item “6. Misc Setup,” then press the
[SEL(SET)] key.
ˆ Rotate the DIAL selector knob to select Sub Menu Item “1. APO,” then press the
[SEL(SET)] key.
ˆ Press the [SEL(SET)] key again to enable adjustment of this Menu Item.

ˆ When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exits to normal operation.
When the APO is activated, the “TIMER” icon will appear at the center bottom on the LCD. If
there is no action by you within the time interval programmed, the “TIMER” icon blinks and a
ringer sounds one minute before the APO shut-down time; one minute thereafter, the
microprocessor will shut down the radio automatically.

Operating Manual
Just press and hold in the (PWR) switch for 3 seconds to turn the transceiver back on after
an APO shutdown, as usual.
Transmitter Time-Out Timer (TOT)
The TOT feature provides a safety switch which limits transmission to a pre-programmed
value. This will promote battery conservation by not allowing you to make excessively-long
transmissions, and in the event of a stuck PTT switch (perhaps if the radio or a Speaker/Mic
is wedged between aircraft’s seats) it can prevent interference to other users as well as
battery depletion. As configured at the factory the TOT feature is set to OFF, and here is the
procedure for activating it:
ˆ Press [F] key followed by [SEL(SET)] key to activate the Menu (“SET”) mode.
ˆ Rotate the DIAL selector knob to select Menu Item “4. Transmit,” then press the
[SEL(SET)] key.
ˆ Rotate the DIAL selector knob to select Sub Menu Item “4. T.O.T.” then press the
key.
ˆ Press the [SEL(SET)] key again to enable adjustment of this Menu Item.

time (1 minute, 3 minutes or 5 minutes).
ˆ When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exit to normal operation.
Note 1: When your transmitting time is within 10 seconds of the Time-Out Timer expiration,
an alert bell will provide an audible warning from the speaker.
Note 2: Since brief transmissions are the mark of a good operator, try setting up your radio’s
TOT feature for a maximum transmission time of 1 minute. This will significantly improve
battery life, too!
Programming the Key Assignments
The [USER(KEY)] key is a user-programmable key that may be set up for a pair of functions

Busy Channel Lock-Out (BCLO)
The BCLO feature prevents the radio’s transmitter from being activated if a signal strong
enough to break through the “Noise” squelch is present. On a frequency where stations
using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting
their communications accidentally (because your radio may be muted by its own Tone
