3. 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
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!
Clip the Quick-Draw Belt Clip onto your belt (Figure 2).
To install the VXA-710 into the Quick-Draw Belt Clip, align the hanger with the Quick-
Draw Belt Clip, and slide the VXA-710 into its slot until a click is heard (Figure 3).
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
6
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.
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.
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
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.

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.
Basic Operation
Preliminary Steps
Install a charged battery pack onto the transceiver, as described previously.
Screw the supplied antenna onto the Antenna jack. Never operate this transceiver
without an antenna connected.

Operating Manual
FM BC band.
Directly entering frequencies from the keypad is the easiest method if you know the
frequency on which you wish to operate. Just enter the five digits of the frequency to
move to that frequency. However, there is a short-cut for frequencies ending in zero -
press the [SCAN(DW)MT] key after the last non-zero digit.
For example, to set 134.35 MHz:
press [1] Æ [3] Æ [4] Æ [3] Æ [5].
To set 118.000 MHz:
press [1] Æ [1] Æ [8] Æ [SCAN(DW)MT].
To set 118.275 MHz, you do not need to press the final “5” in the frequency:
press [1] Æ [1] Æ [8] Æ [2] Æ [7].
Note: When the entered frequency is outside of the current operating band, the entry is
ignored (i.e. VXA-710 does not permit entry of a FM BC band frequency while operating
in the AIR band).
You may also turn the top panel’s DIAL selector knob to choose the desired operating
frequency. The channel frequency will appear on the LCD.
To change frequency in 1 MHz steps, press the [F] key momentarily, then rotate the
DIAL selector knob to select the MHz digit desired. Press the [F] key once more to
resume normal channel step.
Rotate the VOL knob to set the volume level. If no signal is present, press and hold in
the MONITOR button for 2 seconds; background noise will now be heard, and you may
use this noise to set the VOL knob for the desired audio level. Press the MONITOR
button momentarily to silence the noise and resume normal (quiet) monitoring.
To turn the radio off, press and hold in the PWR switch for 3 seconds.
Squelch Adjustment
Press and hold in the [0(SQ)] key for 3 seconds. This instantly recalls Menu Item “SQL:”
on the AM or FM mode or “WSQL:” on the WFM mode (for the Broadcasting Station).
Press the [SEL(SET)] key to enable adjustment of this Menu Item.
Rotate the DIAL selector knob to set the squelch threshold (0 - 8) so that the receiver is
just silenced. A higher number indicates that a higher signal level is required in order to
open the squelch.
When you have made your setting, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exits to normal operation.

Note 1: In the event of extreme weather disturbances, such as storms and hurricanes, the
NOAA (National Oceanic and Atmospheric Administration) sends a weather alert
accompanied by a 1050 Hz tone and subsequent weather report on one of the NOAA
weather channels. You may setup the Alert function when receiving the Weather Alert signal
via Menu Item (6. Misc Setup, 3. WX Alert), if desired.
Note 2: The Weather Channel mode memorizes the last Weather Channel you have used,
and will retain this information until the radio is turned off.
Receive Battery Saver Setup
An important feature of the VXA-710 is its Receive Battery Saver, which “puts the radio to
sleep” for a time interval, periodically “waking it up” to check for activity. If somebody is
talking on the channel, the VXA-710 will remain in the “active” mode, then resume its “sleep”
