Precautions
r This apparatus is capable of two-way communi-
cation 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.
r When making DC connections via the 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-120 directly to a source
which exceeds 15.0 Volts DC will result in damage to the unit.
r Do not dispose of the Ni-Cd Battery Pack in a
fire. Do not carry a Ni-Cd 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 Ni-Cd
pack.
r Although the VXA-120 is designed to be water
resistant, the enclosure is not “waterproof.” Do
not allow the radio to become submersed in water, and do not expose it and/or its Ni-Cd Battery
Pack to water spray under pressure.
Battery Installation and Removal
¦ To install the battery, hold the transceiver with
your left hand, so your palm is over the speaker
and your thumb is on the top of the Belt Clip.
Insert the battery pack into the battery compartment on the back of the radio while tilting the
Belt Clip outward, then close the Battery Pack
Latch until it locks in place with a “Click.”
¦ To remove the battery, turn the radio off and re-
move any protective cases. Open the Battery Pack
Latch on the bottom of the radio, then slide the
battery downward and out from the radio while
unfolding the Belt Clip.
Do not attempt to open any of the recharge-
able Ni-Cd packs, as personal injury or damage to the Ni-Cd pack could occur if a cell or cells
become accidentally short-circuited.

Battery Charging
It is necessary to fully charge the Ni-Cd battery before it’s first use. Follow these procedures:
¦ Install the supplied FNB-V57 Ni-Cd battery pack
onto the transceiver. Ensure that the transceiver
is switched off.
¦ Plug the NC-76 into the AC line outlet.
¦ Insert the battery pack into the NC-76; the an-
tenna jack should be at the left side when viewing the charger from the front.
¦ If the battery pack is inserted correctly, the RED
indicator will glow . A fully-discharged pack will
be charged completely in 15 hours.
Important Notes:
r The NC-76 is not designed to power the trans-
ceiver for operation (reception or transmission).
r Do not leave the charger connected to the trans-
ceiver for continuous periods in excess of 24
hours. Long term overcharging can degrade the
Ni-Cd battery pack and significantly shorten its
useful life.
r If using a charger other than the NC-76 , or if
using a battery pack other than the FNB-V57,
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.
Must be transceiver
switched off.

Low Battery Indication
¦ As your battery discharges during use, the volt-
age will gradually become lower. When the battery voltage reaches 5.0 Volts, the “ x ” icon
will blink on the LCD display, indicating that
the battery pack must be recharged before further use.
¦ Avoid recharging Ni-Cd batteries before the
“Low Battery” indicator is observed, as this can
degrade the charge capacity of your Ni-Cd battery pack. Yaesu recommends that you carry an
extra, fully-charged pack with you so you will
not lose communications capability due to a depleted Ni-Cd battery.
This “deep cycling” practice will help to maintain longer overall battery life after many recharging cycles.
Installing the FBA-25 (option) Alkaline
Battery Case
The optional FBA-25 Battery Case allows operation of the VXA-120 using six “AA” size Alkaline
batteries.
When installing batteries, insert the (–) end first, then
