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
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!

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 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.
Install the FNB-80LI as shown in the illustration.
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.
VXA-710 SPIRIT OPERATING MANUAL
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 ~ 15 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. “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 us-
ing 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
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.
Open the Battery Pack Latch on the
bottom of the radio.
. 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 re-charged. 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.
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, re-
move the Alkaline batteries from the FBA-23, as battery leakage could cause damage to the FBA-23 and/
or the transceiver.

VXA-710 SPIRIT OPERATING MANUAL
BEFORE YOU BEGIN
Low Battery Indication
As you battery discharges during use, the voltage will
gradually become lower. When the “ ” begins
blinking on the LCD display, the battery pack
must be recharged before
further use.
Avoid recharging Li-Ion batteries before the “Low Bat-
tery” indicator is observed, as this can degrade the
charge capacity of your Li-Ion battery pack. Vertex
Standard recommends that you carry an extra, fullycharged 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.

MEMORY OPERATION
The VXA-710 provides 70 user-programmable Main
memories, labeled “MR1” through “MR68”, “MRLch,”
and “MRUch,” up to 90 pre-programmed memories, designated “Book” Memories, labeled “BMR1” through
“BMR90,” and one Home channel, allowing storage and
quick recall of favorite operating frequency.
The Main memories and “Book” Memories can be assigned
alpha-numeric names of up to eight characters.
Memory System Operation
The VXA-710’s Main Memory system allows the user to
store, label, and recall channel frequencies which you may
want to use frequently. You may store VFO frequencies,
“Book” Memory frequencies, and/or Weather Channel frequencies (USA version only) into the Main Memory system.
Memory Storage
Select the desired frequency in the VFO mode, or re-
call the “Book” Memory channel or Weather channel
to be stored in the Main Memory.
Press and hold in the key for 2 seconds. The dis-
play will indicate “MW” and a channel number will
blink on the LCD.
Within five seconds of pressing the key, rotate the
DIAL selector knob to select the desired memory chan-
nel number for storage. In order to prevent writing
over memory channels, an “ ” icon will appear at
the right of the channel number to indicate if the
memory channel is vacant.
Now press and hold in the key for 2 seconds; you
will now see the blinking “A” character on the LCD.
To attach an alpha/numeric name (label) to the
memory, proceed to the next step; otherwise press and
hold in the key for 2 seconds to save the entry and
exit.
To label a memory with an alpha/numeric name, the
next step is to use the DIAL selector knob to select
any of the 125 available characters (including letters,
numbers, and special symbols). Press the key repeatedly to recall the desired letter, number, and symbol in the first charactor slot (a . 0 A a ...).
When the desired first character appears, press the
key momentarily to select it and move on to the next
character.

VXA-710 SPIRIT OPERATING MANUAL
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 Memory 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 avail-
*
able 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.
Press the key momentarily to start the automatic
scanner upward (toward a higher frequency or a higher
channel number).
When the scanner encounters a signal, scanning pauses
and the radio remains on that channel until one sec-
VXA-710 SPIRIT OPERATING MANUAL
ond after the signal disappears, after which scanning
will resume.
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.
To change the scan direction, turn the DIAL selector
knob one click in the opposite direction.
To stop the automatic scanner, press the PTT switch
or the 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:
Press and hold the key to start the manual scan-
ner. Scanning will continue as long as the key is depressed.
Release the key to stop the manual scanner im-
mediately.
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.
23
SCANNING OPERATION
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:
Recall the Memory Channel to be skipped during scan-
ning.
Press and hold the 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.
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. Here’s how to do this:
Set the radio to the VFO mode by pressing the
key and set the radio to the AIR band by pressing the
key, if necessary.
Using the techniques learned earlier, store 118.000
MHz into Memory Channel “Lch” (the “Lch” designates the Lower sub-band limit).
Likewise, store 136.975 MHz into Memory Channel
“Uch” (the “Uch” designates the Upper sub-band
limit).
Switch to the Memory mode by pressing the key
once, then rotate the DIAL to select Memory Channel
“Lch.”
Press and hold in the key for 2 seconds to start
PMS operation; the “MR” label will be replaced by
“PMS” in the upper left-hand corner of the display.
Tuning and scanning (pressing the key) will now
be limited within the just-programmed range.
)
24
Note: The PMS feature will not engage if a BRS channel
is stored in either the “Lch” or “Uch” memory slot.
VXA-710 SPIRIT OPERATING MANUAL
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.
To start Dual Watch, press the key followed by
the key.
The “DW” icon will ap-
pear on the display.
While receiving on the
“current” channel (not the
Priority channel), you may push the PTT switch at
any time to transmit on that channel.
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.
While receiving on the priority channel, if you mo-
mentarily press the PTT switch, Dual Watch will be
disabled. You may then transmit on the Priority Channel.
To stop Dual Watch, press the key followed by
the key.
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.
The “Priority” channel is defined as the last-used
*
Memory Channel (when using the VFO, “Book”
memory, and “BRS” modes) or Memory Channel “1”
(when using the Main Memory mode).
VXA-710 SPIRIT OPERATING MANUAL
25
PRIORITY DUAL WATCH OPERATION
Similar to Dual Watch operation (described on previous
page), Priority Dual Watch is an enhanced version which
includes the following additional features:
The receiving time interval (ratio) between the cur-
rent channel and the Priority channel may be customized via the Menu Item “PRI Time.” See page 51 for
details.
Irrespective of which channel is currently being re-
ceived, when the PTT button is pushed transmission
will always occur on the Priority channel.
Before initiating Priority Dual Watch, Menu Item “DW/
PRI” must be set to the “PRI” mode (instead of “DW”).
See page 50 for details.
To start Priority Dual
Watch, press the key
followed by the key.
The “DW” icon will appear on the display.
While receiving on the “current” (non-Priority) chan-
nel, pressing the PTT button once causes the radio to
switch to the Priority channel and cancels Dual Watch.
Press the PTT button again to transmit on the Priority
channel.
When a signal is received on the Priority channel, re-
ception immediately shifts to the Priority channel; the
“DW” icon will blink, and the display will become
illuminated unless the Scan Lamp Feature is turned
off.
While receiving on the Priority channel, if you mo-
mentarily press the PTT switch, Priority Dual Watch
will be disabled. You may then transmit on the Priority Channel.
To stop Priority Dual Watch, press the key fol-
lowed by the key.

VXA-710 SPIRIT OPERATING MANUAL
SPECTRUM SCOPE MONITOR
If you assign the Spectrum Scope Monitor feature to the
key (see page 40), you may view operating activity
on channels above and below the current operating channel while operating in the VFO, Memory Tune, and PMS
modes.
The display indicates the relative signal strength on channels immediately adjacent to the current operating frequency.
Set the radio to the VFO mode by pressing the
key, if necessary.
Press (or press and hold
in) the key to activate
the Spectrum Scope
Monitor.
Once the Spectrum Scope Monitor is activated, press
the key to change the visible bandwidth between
±15 channels and ±30 channels (default: ±30 channels). The visible bandwidth, however, depends on the
selected channel step size, so match the channel step
to those typically used in your area.
To turn the Spectrum Scope Monitor off and operate
on the centered (and displayed) channel, simply press
the PTT switch.
Note 1: Audio output will be interrupted during Spectrum
Analyzer operation. This is normal.
Note 2: The Spectrum Scope Monitor may not be activated on the BRS Memories.

cally. The “Course Indicator” will appear on the dis-
play, and the “TO” or “FROM” indicator will appear
at the right of the “Course Indicator” on the display.
Note: The “COURSE INDICATOR” indicates “---°” when
either your aircraft is too far away from the VOR sta-
tion or if the frequency is not correctly set to that of
the VOR station. Conversely, the “Course Indicator”
will indicate “Loc” when a localizer signal is being
received.
The “TO” or “FROM” flag indicators indicate whether
the VOR navigation information is based on a course
leading to the VOR station or leading away from the
VOR station.
To change the flag from “TO” to “FROM” or vice versa,
press the key followed by the key or key,
respectively.
The (small) frequency indication may be toggled to

CTCSS Operation
The VXA-710 can be used to silently monitor for calls on
busy channels of the BRS band. The CTCSS decoder
monitors receiver audio through a narrow filter at the same
subaudible frequency, keeping the squelch closed until a
matching tone is received.
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 and keys, or Menu
Items (SQL Type) and (TONE Set).
Press and hold the key for 3 seconds. This instantly
recalls Menu Item (SQL Type).
Press the key again to enable adjustment of this
