crophone to this jack. Never connect the any Speaker/Micro-

phone that is not recommended by the manufacturer. Because these jack connections are unique using a Speaker/Microphone that is not specified by Yaesu will damage the VXA-120. EXT DC Jack When an external 12-Volt DC power source is available, you may connect the E-DC-5B Exter-

nal 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-120 di-

rectly to a source which exceeds 15.0 Volts DC will result in damage to the unit. VXA-120 AVIATOR PROII OPERATING MANUAL 7 BEFORE YOU BEGIN 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 dam-

age 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 ter-

minals. This could create a serious fire/burn dan-

ger, 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 wa-

ter, 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 compart-

ment 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 dam-

age to the Ni-Cd pack could occur if a cell or cells become accidentally short-circuited. VXA-120 AVIATOR PROII OPERATING MANUAL 8 BEFORE YOU BEGIN Battery Charging It is necessary to fully charge the Ni-Cd battery be-

fore its 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 view-

ing 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. 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. To AC line outlet 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 VXA-120 AVIATOR PROII OPERATING MANUAL VXA-120/NC-76 9 BEFORE YOU BEGIN 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 icon will blink on the LCD display, indicating that the battery pack must be recharged before fur-

ther use. Avoid recharging Ni-Cd batteries before the Low Battery indicator is observed, as this can degrade the charge capacity of your Ni-Cd bat-

tery pack. Yaesu recommends that you carry an extra, fully-charged pack with you so you will not 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. Installing the FBA-25 (option) Alkaline Battery Case The optional FBA-25 Battery Case allows opera-

tion of the VXA-120 using six AA size Alkaline batteries. When installing batteries, insert the () end first, then press 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. 10 VXA-120 AVIATOR PROII OPERATING MANUAL 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.

ments), typically including the major COMCOMCOMCOMCOM and NAVNAVNAVNAVNAV band station frequencies used in your area. The Book memories can be changed by the user. See page 27 for details. WX (Weather Channel) Memories Ten Weather Channels are pre-programmed at the 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. Tuning Methods Throughout this manual, you will see references to several different frequency setting methods. Each will be particularly useful in a particular operating situa-

tion, and they are described below:

VFO (Variable Frequency Oscillator) The VFO is a tuning dial system which al-

l o w s y o u t o t u n e through the NAVNAVNAVNAVNAV or COMCOMCOMCOMCOM bands in 25-kHz steps using the CHANNEL selector, the Keypad, or the scanner. MR (Memory Recall) The MR (Memory Re-

call) mode of the VXA-

120 provides the user with the ability to store and recall as many as 50 channels in the radios main memory bank. These memory channels may also be labeled by you with an alpha/numeric name of up to 8 charac-

ters in length, to aid in quick identification of the channel. See page 20 for details on creating alpha/numeric labels. 14 VXA-120 AVIATOR PROII OPERATING MANUAL OPERATION Transmission To transmit, press and hold the PTT switch. Speak into the micro-

phone area of the front panel grille in a normal voice level. To return to the receive mode, release the PTT switch. VXA-120 AVIATOR PROII OPERATING MANUAL Reception of Weather Channel Broadcasts The VXA-120 can receive VHF Weather Channel broadcasts, which may assist your flight planning. The VXA-120 includes a ten-channel auto-search feature, which simplifies access to Weather Chan-

nels when you are in an unfamiliar location. r To receive Weather Channels, press the CHANNEL selector knob (repeatedly, if necessary) to select the Weather Channel mode. In the Weather Channel mode, " WX " will appear on the dis-

play. r The VXA-120 will now scan quickly through the ten standard Weather Channels, and will stop on the first active station found. r If there are two or more weather chan-

nels audible in your area, you may select the alternate chan-

nel(s) by pressing the PTT switch. Pressing 15 OPERATION the PTT switch re-initiates the scanning process. r I f t h e r e a r e n o Weather Channels in your area, the scan-

ner will not stop. Press the MONITOR button to stop the scanner. r You can also select Weather Channels manually by rotating the CHANNEL se-

lector knob. r To exit the Weather Channel mode, press the CHANNEL se-

lector knob momen-

tarily to return to the VFO mode. Note: The Weather Channel mode memorizes the last Weather Channel you have used, and will retain this information until the radio is turned off. r To comfirm the current Weather Channel fre-

quency, press the [

)] key momen-

tarily. The display changes to frequency indication. Press the

)] key again

to return to normal display.

16 VXA-120 AVIATOR PROII OPERATING MANUAL OPERATION Monitor Key When listening to a very weak signal from an air-

craft or ground station, you may observe the signal disappearing periodically as the incoming signal strength becomes too weak to override the squelch threshold setting. To disable the squelch temporarily, press and hold the MONITOR key for 2 seconds on the left side of the radio, just be-

low the PTT button. The squelch will remain open and you should have a better chance of hearing weak signals. To return to normal operation, press the MONITOR key momentarily.

sume normal channel selection in 1 channel step. 21 SCANNING OPERATION The VXA-120 allows you to scan automatically in the VFO*, Main Memory, Book Memory, or Weather 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 only available in the COMCOMCOMCOMCOM band (118.000 - 136.975 MHz);

when the scanner reaches the uppermost frequency in the COMCOMCOMCOMCOM band, it will revert to the bottom end of the COMCOMCOMCOMCOM band and repeat the scanning process until you cancel the scanning process. If you wish to scan in the NAVNAVNAVNAVNAV band (108.000 -

136.975 MHz), you can do so manually, as described at the right. Scanning operation is basically the same in each of the above modes. r Press the [SCAN (DW)] key momentarily to start the automatic scanner upward (toward a higher frequency or a higher channel number). r When the scanner encounters a signal, scanning pauses and the radio remains on that channel until one second after the signal disappears, after which scanning will resume. 22 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 switch or the CHANNEL selector knob momentarily. You may also press [SCAN (DW)] key again. The VXA-120s automatic scanner is not operational in the NAVNAVNAVNAVNAV band (108.000 - 117.975 MHz), because the 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 start the manual scanner. Scanning will continue as long as the key is depressed. r Release the [SCAN (DW)] key to stop the manual scanner immediately. Note: When scanning upward in frequency, when the frequency reaches the COMCOMCOMCOMCOM Band (118.000 - 136.975 MHz) via manual scanning, the VXA-120 will switch to the automatic scanner mode. VXA-120 AVIATOR PROII OPERATING MANUAL SCANNING OPERATION Channel-Skip Scanning Continuous-carrier stations like ATIS (Automatic Terminal Information Service) or Weather Broadcast stations inhibit scanner operation. Since these sta-

tions are always active, the scanner will be halted repeatedly on their channels. Such channels can be set to be skipped during scanning, if you like, so as not to interfere with automatic channel scanning:

r Recall the Memory Channel to be skipped dur-

ing scanning. r Press [F] [9 (SKIP)] key. The SKIP icon will appear in the lower right corner, indicating that the channel is to be ignored during scanning. r You can also designate a channel to be skipped while scanning. When the receiver is halted on a channel 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 be skipped). r Later, to re-enable the memory channel for scan-

ning, repeat the first two steps. The SKIP icon will 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. VXA-120 AVIATOR PROII OPERATING MANUAL 23 DUAL WATCH OPERATION The Dual Watch feature automatically checks for activity on a priority channel* while you are oper-

ating on another channel. During Dual Watch opera-

tion, the current channel and the Priority channel will each be polled for a 500 ms interval, as the VXA-

120 looks for activity on each channel. r To start Dual Watch, press [F] [SCAN (DW)]. The DW icon will appear on the display. r While receiving on the current channel (not the Priority channel), you may push the PTT switch at any time to transmit on that channel. r When a signal is received on the Priority chan-

nel, operation immediately shifts to the Priority channel, the DW icon will blink, and the dis-

play and keypad will become illuminated. While receiving on the priority channel, if you momentarily press the PTT switch, Dual Watch will be disabled. You may then transmit on the Priority Channel. r To stop Dual Watch, press [F] [SCAN (DW)]

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

* The Priority Channel is defined as the last-used Memory Channel (when using the VFO mode) or Memory Channel 1 (when using the Main Memory or Book Memory modes). 24 VXA-120 AVIATOR PROII OPERATING MANUAL PRIORITY DUAL WATCH OPERATION Similar to Dual Watch operation (described above), Priority Dual Watch is an enhanced version which includes the following additional features:

l The receiving time interval (ratio) between the current channel and the Priority channel may be customized via the Menu mode, item PRTM. See page 28 for details. l Irrespective of which channel is currently being received, when the PTT button is pushed trans-

mission will always occur on the Priority chan-

nel. Before initiating Priority Dual Watch, Menu item DWMD must be set to the Priority mode (instead of Dual Watch). See page 28 for details. r To start Priority Dual Watch, press [F] [SCAN

(DW)]. The DW icon will appear on the display. r While receiving on the current (non-Priority) channel, pressing the PTT button once causes the radio to switch to the Priority channel and cancels Dual Watch. Press the PTT button again to transmit on the Priority channel. r When a signal is received on the Priority chan-

nel, reception immediately shifts to the Priority channel, DW icon will blink, and the display and keypad will become illuminated unless the Scan Lamp Feature is turned off. While receiving on the priority channel, if you momentarily press the PTT switch, Priority Dual Watch will be disabled. You may then transmit on the Priority Channel. r To stop Priority Dual Watch, press [F] [SCAN

(DW)] key. VXA-120 AVIATOR PROII OPERATING MANUAL 25 SPLIT OPERATION The split operation feature allows you to transmit a call to a Flight Service Station using the COMCOMCOMCOMCOM band frequencies, while receiving a NAVNAVNAVNAVNAV band station
