crophone to this jack. Never connect any Speaker/Microphone that is not recommended by the manufac-

turer. Because these jack connections are unique, using a Speaker/Microphone that is not specified by Vertex Standard may damage the VXA-150. EXT DC Jack When an external 12-Volt DC power source is available, you may connect the (optional) E-DC-

5B External DC Cable here. Do not connect any wire to this jack if that wire is connected di-

rectly to a 28-Volt DC source. Connecting the VXA-150 directly to a source which exceeds 15.0 Volts DC will result in damage to the unit. VXA-150 AVIATOR PROV OPERATING MANUAL 9 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 (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-150 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 ter-

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

ger, and possibly cause damage to the Ni-Cd pack. r Although the VXA-150 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-150 AVIATOR PROV OPERATING MANUAL 10 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-64 Ni-Cd battery pack onto the transceiver. Ensure that the transceiver is switched off. Lift up the rubber cover to expose the EXT DC jack. Plug the cable plug from the NC-72 charger into this jack. Plug the NC-72 into the AC line outlet. Allow a minimum of 15 hours for the FNB-64 to reach full charge. Leave the transceiver switched off this entire period. Unplug the cable from the EXT DC jack. Re-

place the rubber cover to protect the jack. Switch on the transceiver and begin operation. r If using a charger other than the NC-72, or if using a battery pack other than the FNB-64, fol-

low 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. Transceiver must be switched off. To AC line outlet Important Notes:

r The NC-72 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. VXA-150 AVIATOR PROV OPERATING MANUAL VXA-150/NC-72 11 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 6.0 Volts, the 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. Vertex Standard 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 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-150 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. 12 VXA-150 AVIATOR PROV 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 COM and NAV band station frequencies used in your area. The Book memories can be changed by the user. See page 29 for details. WX (Weather Channel) Memories

(USA version only) Ten Weather Channels are pre-programmed at the factory as appropriate for your country, and the VXA-150 will automatically scan this spe-

cial bank when it is selected 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 NAV or COM 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-

150 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 22 for details on creating alpha/numeric labels. 16 VXA-150 AVIATOR PROV OPERATING MANUAL OPERATION Transmission To transmit, press and hold the PTT switch. Speak into the micro-

mal channel selection in 1 channel steps. 23 SCANNING OPERATION The VXA-150 allows you to scan automatically in the VFO1, Main Memory, Book Memory, or Weather Channel2 modes. It pauses on signals en-

countered, so you can talk to the station(s) on that frequency, if you like. 1: In the VFO mode, the automatic scanner is only available in the COM band (118.000 - 136.975 MHz); when the scanner reaches the uppermost fre-

quency in the COM band, it will revert to the bot-

tom end of the COM band and repeat the scanning process until you cancel the scanning process. 2: USA version only. If you wish to scan in the NAV band (108.000 -

117.975 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. 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-150s automatic scanner is not operational in the NAV band (108.000 - 117.975 MHz), because the NAV stations (ILS, etc.) transmit constantly

(thereby causing the scanner to stop repeatedly). However, you can scan manually in the NAV 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. 24 VXA-150 AVIATOR PROV 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)]. 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-150 AVIATOR PROV OPERATING MANUAL 25 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-

150 looks for activity on each channel. r To start Dual Watch, press [F] [SCAN (DW)].
