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).

BEFORE YOU BEGIN

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.

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 illustra-

tion, to the EXT DC jack. If only 12 ~ 15 Volt DC power is avail- able, 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 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.

VXA-710 SPIRIT OPERATING MANUAL

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-23Slide the batteries into the FBA-23

as shown in the illustration, with the Negative [–] side of the batteries touching the spring connections in-

side 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, remove 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 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, 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.

VXA-710 SPIRIT OPERATING MANUAL

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.
