CONTROLS & CONNECTORS (LEFT SIDE)


CONTROLS & CONNECTORS (RIGHT SIDE)

MIC/EAR JackYou may connect the (optional) CT-60 HeadsetCable or the (optional) MH-44A4B Speaker/Mi-crophone to this jack.

Never connect the any Speaker/Micro-phone that is not recommended by the

manufacturer. Because these jack connections areunique using a Speaker/Microphone that is notspecified by Yaesu will damage the VXA-120.

EXT DC JackWhen an external 12-Volt DC power source isavailable, you may connect the E-DC-5B Exter-nal DC Cable here. Do not connect any wire tothis jack if that wire is connected directly to a28-Volt DC source. Connecting the VXA-120 di-rectly to a source which exceeds 15.0 Volts DCwill result in damage to the unit.


BEFORE YOU BEGIN

Precautionsr This apparatus is capable of two-way communi-

cation on channels used for critical aviation safetycommunications. Therefore, it is important thatthis radio be kept away from children or otherunauthorized users at all times.

r When making DC connections via the E-DC-5BDC cable, be absolutely certain to observe theproper voltage level and polarity guidelines. Donot connect this radio directly to any 24 ~ 28Volt DC source, nor to AC power of any kind.Connecting the VXA-120 directly to a sourcewhich exceeds 15.0 Volts DC will result in dam-age to the unit.

r Do not dispose of the Ni-Cd Battery Pack in afire. Do not carry a Ni-Cd Battery Pack in yourpocket, where keys or coins could short the ter-minals. This could create a serious fire/burn dan-ger, and possibly cause damage to the Ni-Cdpack.

r Although the VXA-120 is designed to be waterresistant, the enclosure is not “waterproof.” Donot allow the radio to become submersed in wa-ter, and do not expose it and/or its Ni-Cd BatteryPack 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 speakerand your thumb is on the top of the Belt Clip.Insert the battery pack into the battery compart-ment on the back of the radio while tilting theBelt Clip outward, then close the Battery PackLatch 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 PackLatch on the bottom of the radio, then slide thebattery downward and out from the radio whileunfolding the Belt Clip.

Do not attempt to open any of the recharge-able Ni-Cd packs, as personal injury or dam-

age to the Ni-Cd pack could occur if a cell or cellsbecome accidentally short-circuited.


the charger/battery. Contact your Dealer if youhave any doubts about the appropriateness of theparticular charger or battery pack you intend touse.

BEFORE YOU BEGIN

Battery ChargingIt is necessary to fully charge the Ni-Cd battery be-fore it’s first use. Follow these procedures:

¦ Install the supplied FNB-V57 Ni-Cd battery packonto the transceiver. Ensure that the transceiveris 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 view-ing the charger from the front.

¦ If the battery pack is inserted correctly, the REDindicator will glow. A fully-discharged pack willbe 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 24hours. Long term overcharging can degrade theNi-Cd battery pack and significantly shorten itsuseful life.

r If using a charger other than the NC-76, or ifusing a battery pack other than the FNB-V57 ,follow the appropriate instructions provided with VXA-120/NC-76

To AC line outlet

Must be transceiverswitched off.


Low Battery Indication¦ As your battery discharges during use, the volt-

age will gradually become lower. When the bat-tery voltage reaches 5.0 Volts, the “x ” iconwill blink on the LCD display, indicating thatthe battery pack must be recharged before fur-ther use.

¦ Avoid recharging Ni-Cd batteries before the“Low Battery” indicator is observed, as this candegrade the charge capacity of your Ni-Cd bat-tery pack. Yaesu recommends that you carry anextra, fully-charged pack with you so you willnot lose communications capability due to a de-pleted Ni-Cd battery.This “deep cycling” practice will help to main-tain longer overall battery life after many recharg-ing cycles.

BEFORE YOU BEGIN

Installing the FBA-25 (option) AlkalineBattery CaseThe optional FBA-25 Battery Case allows opera-tion of the VXA-120 using six “AA” size Alkalinebatteries.

When installing batteries, insert the (–) end first, thenpress in the (+++++) end so the battery snaps into place.Always replace all six batteries at the same time, pay-ing attention to the polarity indicated inside the case.

The FBA-25 must not be used with re-chargeable cells. The FBA-25 does not con-

tain the thermal and over-current protection cir-cuits (provided in the “FNB” series of Ni-Cd Bat-tery Packs) required when utilizing Ni-Cd cells.


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 anantenna connected.

¦ If you have an optional Speaker/Microphone orheadset, we recommend that it not be connecteduntil you are familiar with the basic operation ofthe VXA-120.

Operation Quick Startr To turn the radio on,

rotate the VOLUMEknob out of the click-stop.

Tuning MethodsThroughout this manual, you will see references toseveral different frequency setting methods. Each willbe particularly useful in a particular operating situa-tion, and they are described below:

¦ VFO (Variable Frequency Oscillator)The VFO is a “tuningdial” system which al-l ows you to t unethrough the NAVNAVNAVNAVNAV or COMCOMCOMCOMCOM bands in 25-kHz stepsusing the CHANNEL selector, the Keypad, orthe scanner.

¦ MR (Memory Recall)The MR (Memory Re-call) mode of the VXA-120 provides the userwith the ability to store and recall as many as 50channels in the radio’s main memory bank. Thesememory channels may also be labeled by youwith an alpha/numeric name of up to 8 charac-ters in length, to aid in quick identification ofthe channel. See page 20 for details on creatingalpha/numeric labels.

¦ BOOK (Pre-Programmed) MemoriesThe Book memories arepre-programmed, eitherat the factory or by yourDealer (depending on your country’s require-ments), typically including the major COMCOMCOMCOMCOM andNAVNAVNAVNAVNAV band station frequencies used in your area.The Book memories can be changed by the user.See page 27 for details.

¦ WX (Weather Channel) MemoriesTen Weather Channelsare pre-programmed atthe factory as appropri-ate for your country, and the VXA-120 will au-tomatically scan this special bank when it is se-lected by the user.

SCANNING OPERATION

The VXA-120 allows you to scan automatically inthe VFO*, Main Memory, “Book” Memory, orWeather Channel modes. It pauses on signals encoun-tered, so you can talk to the station(s) on that fre-quency, if you like.

* In the VFO mode, the automatic scanner is onlyavailable in the COMCOMCOMCOMCOM band (118.000 - 136.975 MHz);when the scanner reaches the uppermost frequencyin the COMCOMCOMCOMCOM band, it will revert to the bottom end ofthe COMCOMCOMCOMCOM band and repeat the scanning process untilyou cancel the scanning process.

If you wish to scan in the NAVNAVNAVNAVNAV band (108.000 -136.975 MHz), you can do so manually, as describedat the right.

Scanning operation is basically the same in each ofthe above modes.

r Press the [SCAN (DW)] key momentarily to startthe automatic scanner upward (toward a higherfrequency or a higher channel number).

r When the scanner encounters a signal, scanningpauses and the radio remains on that channel untilone second after the signal disappears, afterwhich scanning will resume.

r While the scanner remains paused on a frequency,the decimal point of the frequency display blinks.The display and keypad will be illuminated un-less the Scan Lamp Feature is turned off.

r To change the scan direction, turn the CHAN-NEL selector knob one click in the opposite di-rection.

r To stop the automatic scanner, press the PTT switchor the CHANNEL selector knob momentarily. Youmay also press [SCAN (DW)] key again.

The VXA-120’s automatic scanner is not operationalin the NAVNAVNAVNAVNAV band (108.000 - 117.975 MHz), becausethe NAVNAVNAVNAVNAV stations (ILS, etc.) transmit constantly(thereby causing the scanner to stop repeatedly).However, you can scan manually in the NAVNAVNAVNAVNAV band,per the following procedure:

r Press and hold the [SCAN (DW)] key to startthe manual scanner. Scanning will continue aslong as the key is depressed.

r Release the [SCAN (DW)] key to stop themanual scanner immediately.

Note: When scanning upward in frequency, when thefrequency reaches the COMCOMCOMCOMCOM Band (118.000 - 136.975MHz) via manual scanning, the VXA-120 will switchto the automatic scanner mode.


SCANNING OPERATION

Channel-Skip ScanningContinuous-carrier stations like ATIS (AutomaticTerminal Information Service) or Weather Broadcaststations inhibit scanner operation. Since these sta-tions are always active, the scanner will be haltedrepeatedly on their channels. Such channels can beset to be “skipped” during scanning, if you like, soas not to interfere with automatic channel scanning:

r Recall the Memory Channel to be skipped dur-ing scanning.

r Press [F] à [9 (SKIP)] key. The “SKIP” iconwill appear in the lower right corner, indicatingthat the channel is to be ignored during scanning.

r You can also designate a channel to be skippedwhile scanning. When the receiver is halted on achannel that you wish to skip, press and hold the[SCAN (DW)] key for 2 seconds (the “SKIP”icon will appear next to the channel to beskipped).

r Later, to re-enable the memory channel for scan-ning, repeat the first two steps. The “SKIP” iconwill disappear by the channel you have just re-enabled.

Note: A memory set to be “skipped” is still acces-sible for manual memory selection using the CHAN-NEL selector knob.


DUAL WATCH OPERATION

The Dual Watch feature automatically checks foractivity on a “priority” channel* while you are oper-ating on another channel. During Dual Watch opera-tion, the current channel and the Priority channel willeach be polled for a 500 ms interval, as the VXA-120 looks for activity on each channel.

r To start Dual Watch, press [F] à [SCAN (DW)].The “DW” icon will appear on the display.

r While receiving on the “current” channel (notthe Priority channel), you may push the PTTswitch at any time to transmit on that channel.

r When a signal is received on the Priority chan-nel, operation immediately shifts to the Prioritychannel, the “DW” icon will blink, and the dis-play and keypad will become illuminated.

While receiving on the priority channel, if youmomentarily press the PTT switch, Dual Watchwill be disabled. You may then transmit on thePriority Channel.

r To stop Dual Watch, press [F] à [SCAN (DW)]key.

r If you wish, you may use both the Dual Watchand Scan features simultaneously. To do this, startthe Dual Watch first, then start the Scanner.

* The “Priority” Channel is defined as the last-usedMemory Channel (when using the VFO mode) orMemory Channel 1 (when using the Main Memoryor Book Memory modes).


PRIORITY DUAL WATCH OPERATION

Similar to Dual Watch operation (described above),Priority Dual Watch is an enhanced version whichincludes the following additional features:

l The receiving time interval (ratio) between thecurrent channel and the Priority channel may becustomized via the Menu mode, item PRTM. Seepage 28 for details.

l Irrespective of which channel is currently beingreceived, when the PTT button is pushed trans-mission will always occur on the Priority chan-nel.

Before initiating Priority Dual Watch, Menu itemDWMD must be set to the “Priority” mode (insteadof “Dual Watch”). See page 28 for details.

r To start Priority Dual Watch, press [F] à [SCAN(DW)].The “DW” icon will appear on the display.

r While receiving on the “current” (non-Priority)channel, pressing the PTT button once causesthe radio to switch to the Priority channel andcancels Dual Watch. Press the PTT button againto transmit on the Priority channel.

r When a signal is received on the Priority chan-nel, reception immediately shifts to the Prioritychannel, “DW” icon will blink, and the displayand keypad will become illuminated unless theScan Lamp Feature is turned off.While receiving on the priority channel, if youmomentarily press the PTT switch, Priority DualWatch will be disabled. You may then transmiton the Priority Channel.

r To stop Priority Dual Watch, press [F] à [SCAN(DW)] key.


The split operation feature allows you to transmit acall to a Flight Service Station using the COMCOMCOMCOMCOM bandfrequencies, while receiving a NAVNAVNAVNAVNAV band station(such as the ATIS, AWOS etc.). NAVNAVNAVNAVNAV band stationsequipped with this capability typically are shown,on navigation charts, with the voice calling frequencyin parenthesis above the navigation frequency.
