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-700 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
r Connect the hanger to the rear of the VXA-700, 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-700!
r Clip the Quick-Draw Belt Clip onto your belt (Figure
2).
r To install the VXA-700 into the Quick-Draw Belt Clip,
align the hanger with the Quick-Draw Belt Clip, and
slide the VXA-700 into its slot until a click is heard
(Figure 3).
r To remove the VXA-700 from the Quick-Draw Belt
Clip, rotate the VXA-700 180 degrees, then slide the

NC-72B/C
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.
r Install the FNB-80LI as shown in the illustration.
r 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-700 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 ~ 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, the display will change to indicate “Com-
plete” 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.

BEFORE YOU BEGIN
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
r 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.
r Open the Battery Pack Latch on the
bottom of the radio.
r. Install the FBA-23 as shown in the illustration, with
the [+] side facing the bottom of the transceiver.
r 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-700 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.
10
VXA-700 SPIRIT OPERATING MANUAL
BEFORE YOU BEGIN
Low Battery Indication
¦ As your battery discharges during use, the voltage will
gradually become lower. When the “ ” icon will
blink 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-700 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.
