![FCC ID: K6610623X20IC ID: 511B-10623X20Operating ManualVertex Standard Co., Ltd.8Notes: 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 theFBA-23, as battery leakage could cause damage to the FBA-23 and/or the transceiver.Low Battery Indication As your battery discharges during use, the voltage will gradually become lower. Whenthe “BATTERY” icon will blink on the LCD display, the battery pack must be rechargedbefore further use. Avoid recharging Li-Ion batteries before the “Low Battery” indicator is observed, as thiscan degrade the charge capacity of your Li-Ion battery pack. Vertex Standardrecommends that you carry an extra, fully-charged pack with you so you will not losecommunications capability due to a depleted Li-Ion battery.This “deep cycling” practice will help to maintain longer overall battery life after manyrecharging 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/CBattery Charger. The NC-72B/C should only be used for reception, because it is not capableof supplying sufficient current to support transmission.To use the NC-72B/C, turn the transceiver off, then plug the miniature connector of theBattery Charger into the EXT DC jack on the side of the radio. Now plug the Battery Chargerinto the wall outlet. You may now turn on the transceiver.Basic OperationPreliminary Steps Install a charged battery pack onto the transceiver, as described previously. Screw the supplied antenna onto the Antenna jack. Never operate this transceiverwithout an antenna connected. If you have an optional Speaker/Microphone or headset. we recommend that it not beconnected until you are familiar with the basic operation of the VXA-710.Operation Quick Start To turn the radio on, press and hold in the PWR Switch for 3 seconds. The opening message will appear on the display, then frequency display will appear.

Directly entering frequencies from the keypad is the easiest method if you know thefrequency on which you wish to operate. Just enter the five digits of the frequency tomove to that frequency. However, there is a short-cut for frequencies ending in zero -press the [SCAN(DW)MT] key after the last non-zero digit.For example, to set 134.35 MHz:press [1] Æ [3] Æ [4] Æ [3] Æ [5].To set 118.000 MHz:press [1] Æ [1] Æ [8] Æ [SCAN(DW)MT].To set 118.275 MHz, you do not need to press the final “5” in the frequency:press [1] Æ [1] Æ [8] Æ [2] Æ [7].Note: When the entered frequency is outside of the current operating band, the entry isignored (i.e. VXA-710 does not permit entry of a FM BC band frequency while operatingin the AIR band). You may also turn the top panel’s DIAL selector knob to choose the desired operatingfrequency. The channel frequency will appear on the LCD. To change frequency in 1 MHz steps, press the [F] key momentarily, then rotate theDIAL selector knob to select the MHz digit desired. Press the [F] key once more toresume normal channel step. Rotate the VOL knob to set the volume level. If no signal is present, press and hold inthe MONITOR button for 2 seconds; background noise will now be heard, and you mayuse this noise to set the VOL knob for the desired audio level. Press the MONITORbutton momentarily to silence the noise and resume normal (quiet) monitoring. To turn the radio off, press and hold in the PWR switch for 3 seconds.Squelch Adjustment Press and hold in the [0(SQ)] key for 3 seconds.

To exit the Emergency Frequency, press the [121.5(HOME)] key momentarily.Tuning MethodsThroughout this manual, you will see references to several different frequency settingmethods by pressing the [SEL(SET)] key. Each will be particularly useful in a particularoperating situation, and they are described below: VFO (Variable Frequency Oscillator)The VFO is a “tuning dial” system which allows you to tune through the AIR band andFM BC band using the DIAL selector, the Keypad, or the scanner. To select these bands,press the [BAND(MODE)] key momentarily. MR (Memory Recall)The MR (Memory Recall) mode of the VXA-710 provides the user with the ability tostore and recall as many as 68 channels in the radio’s main memory bank. Thesememory channels may also be labeled by you with an alpha/numeric name of up to 8characters in length, to aid in quick identification of the channel. See page ?? for detailsof the Memory Channel Operation. BOOK (Pre-Programmed) MemoriesThe Book memories are pre-programmed, either at the factory or by your Dealer(depending on your country’s requirements), typically including the major AIR bandstation frequencies used in your area. The Book memories can be changed by the user.See page ?? for details. WX (Weather Channel) Memories (USA version only)Ten Weather Channels are pre-programmed at the factory. The VXA-710 willautomatically scan this special bank when it is selected by the user. See page ?? fordetails of the WX Memory Channel Operation. BRS (Business Radio Service) Memories21 BRS Channels are pre-programmed at the factory.

To receive Weather Channels, press the [SEL(SET)] key (repeatedly, if necessary) toselect the Weather Channel mode. In the Weather Channel mode, “WX” will appearupper left corner of the display. The VXA-710 will now scan quickly though the ten standard Weather Channels, and willstop on the first active station found. If there are two or more weather channels audible in your area, you may select thealternate channel(s) by pressing the PTT switch. Pressing the PTT switch re-initiates thescanning process. If there are no Weather Channels in your area, the scanner will not stop. Press theMONITOR button to stop the scanner. You can also select Weather Channels manually by rotating the DIAL selector knob. To exit the Weather Channel mode, press the key momentarily to return to the VFOmode.Note 1: In the event of extreme weather disturbances, such as storms and hurricanes, theNOAA (National Oceanic and Atmospheric Administration) sends a weather alertaccompanied by a 1050 Hz tone and subsequent weather report on one of the NOAAweather channels. You may setup the Alert function when receiving the Weather Alert signalvia Menu Item (6. Misc Setup, 3. WX Alert), if desired.Note 2: The Weather Channel mode memorizes the last Weather Channel you have used,and will retain this information until the radio is turned off.Receive Battery Saver SetupAn important feature of the VXA-710 is its Receive Battery Saver, which “puts the radio tosleep” for a time interval, periodically “waking it up” to check for activity. If somebody istalking on the channel, the VXA-710 will remain in the “active” mode, then resume its “sleep”](https://usermanual.wiki/Yaesu-Musen/10623X20/User-Guide-510489-Page-12.png)

Press the [F] key followed by [6(TAG)] key to change the readout structure of theMemory display between “Frequency Indication” and “Frequency Indication plus Alpha-numeric Label.”Scanning OperationBasic ScanThe VXA-710 allows you to scan automatically in the VFO*1, Main Memory, “Book” Memory,Weather Channel*2, or BRS channel modes. It pauses on signals encountered, so you cantalk to the station(s) on that frequency, if you like.*1: In the VFO mode, the automatic scanner is only available in the current operating band(AIR band or FM BC band). Furthermore, on the AIR band, the automatic scanner is onlyavailable in the COM band (118.000 - 136.975 MHz); when the scanner reaches theuppermost frequency in the COM band, it will revert to the bottom end of the COM band andrepeat 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, asdescribed below.Scanning operation is basically the same in each of the above modes. Press the [SCAN(DW)MT] key momentarily to start the automatic scanner upward(toward a higher frequency or a higher channel number). When the scanner encounters a signal, scanning pauses and the radio remains on that](https://usermanual.wiki/Yaesu-Musen/10623X20/User-Guide-510489-Page-16.png)
![FCC ID: K6610623X20IC ID: 511B-10623X20Operating ManualVertex Standard Co., Ltd.17channel until one second after the signal disappears, after which scanning will resume. While the scanner remains paused on a frequency, the decimal point of the frequencydisplay blinks. The display will be illuminated unless the Scan Lamp Feature is turnedoff. To change the scan direction, turn the DIAL selector knob one click in the oppositedirection. To stop the automatic scanner, press the PTT switch or the [SCAN(DW)MT] keymomentarily.The VXA-710’s automatic scanner is not operational in the NAV band (108.000 - 117.975MHz), because the NAV stations (ILS, etc.) transmit constantly (thereby causing the scannerto stop repeatedly). However, you can scan manually in the NAV band, per the followingprocedure: Press and hold the [SCAN(DW)MT] key to start the manual scanner. Scanning willcontinue as long as the key is depressed. Release the [SCAN(DW)MT] key to stop the manual scanner immediately.Note: When scanning upward in frequency, when the frequency reaches the COM Band(118.000 - 136.975 MHz) via manual scanning, the VXA-710 will switch to the automaticscanner mode.Channel-Skip ScanningContinuous-carrier stations like ATIS (Automatic Terminal Information Service) or WeatherBroadcast stations inhibit scanner operation. Since these stations are always active, thescanner will be halted repeatedly on their channels. Such channels can be set to be“skipped” during Memory scanning (MR, Book, WX, or BRS modes), if you like, so as not tointerfere with automatic channel scanning: Recall the Memory Channel to be skipped during scanning. Press and hold the [9(SKIP)] key for 2 seconds. The “ icon will appear at the left of thefrequency display, indicating that the channel is to be ignored during scanning. Later, to re-enable the memory channel for scanning, repeat the first two steps. The “icon will disappear by the channel you have just re-enabled.Note: A memory set to be “skipped” is still accessible for manual memory selection usingthe DIAL selector knob.Programmable (Band Limit) Memory Scan (PMS)This feature allows you to set sub-band limits for either scanning or manual VFO operation.For example, you might with to set up a limit of COM band (118.000 MHz to 136.975 MHz.](https://usermanual.wiki/Yaesu-Musen/10623X20/User-Guide-510489-Page-17.png)
![FCC ID: K6610623X20IC ID: 511B-10623X20Operating ManualVertex Standard Co., Ltd.18Here’s how to do this: Set the radio to the VFO mode by pressing the [SEL(SET)] key and set the radio to theAIR band by pressing the [BAND(MODE)] key, if necessary. Using the techniques learned earlier, store 118.000 MHz into Memory Channel “Lch”(the “Lch” designates the Lower sub-band limit). Likewise, store 136.975 MHz into Memory Channel “Uch” (the “Uch” designates theUpper sub-band limit). Switch to the Memory mode by pressing the [SEL(SET)] key once, then rotate the DIALto select Memory Channel “Lch.” Press and hold in the [SCAN(DW)MT] key for 2 seconds to start PMS operation; the“MR” label will be replaced by “PMS” in the upper left-hand corner of the display. Tuning and scanning (pressing the [SCAN(DW)MT] key) will now be limited within thejust-programmed range.Note: The PMS feature does not activated on the WX and BRS frequencies.Dual Watch OperationThe Dual Watch feature automatically checks for activity on a “Priority” channel* while youare operating on another channel. During Dual Watch operation, the current channel and thePriority channel will each be polled for a 500 ms interval, as the VXA-710 looks for activityon each channel. To start Dual Watch, press the [F] key followed by [SCAN(DW)MT] key. The “DW” icon will appear on the display. While receiving on the “current” channel (not the Priority channel), you may push thePTT switch at any time to transmit on that channel. When a signal is received on the Priority channel, operation immediately shifts to thePriority channel; the “DW” icon will blink, and the display will become illuminated. While receiving on the priority channel, if you momentarily press the PTT switch, DualWatch will be disabled. You may then transmit on the Priority Channel. To stop Dual Watch, press the [F] key followed by [SCAN(DW)MT] key. If you wish, you may use both the Dual Watch and Scan features simultaneously. To dothis, start the Dual Watch first, then start the Scanner.* The “Priority” channel is defined as the last-used Memory Channel (when using the VFO,“Book” memory, and BRS channel modes) or Memory Channel “1” (when using the MainMemory mode).Priority Dual Watch OperationSimilar to Dual Watch operation (described on previous page), Priority Dual Watch is an](https://usermanual.wiki/Yaesu-Musen/10623X20/User-Guide-510489-Page-18.png)

The decode function monitors receiver audio through a narrow filter at thesame subaudible frequency, keeping the squelch closed until a matching tone is received,while the transmit (encode) function superimpose a subaudible tone (at a frequency too lowto be heard) on the transmit carrier.The CTCSS setup involves two actions: setting the Tone Mode and then setting of the ToneFrequency. These actions are set up by using the [1(VOR)TN] and [2(TO)CD] keys, or MenuItems (SQL Type) and (TONE Set). Press and hold the [1(VOR)TN] key for 3 seconds. This instantly recalls Menu Item(SQL Type). Press the [SEL(SET)] key again to enable adjustment of this Menu Item. Rotate the DIAL selector knob so that “T” appears at the bottom right corner on thedisplay; this activates the CTCSS Encoder, which allows transmit a CTCSS tone only.Note: You may notice an additional “DCS” icon appearing while you rotate the DIALselector knob in this step. We’ll discuss the Digital Code Squelch system shortly. Rotating the DIAL selector knob in above step will occasionally cause “TSQ” to appear.When “TSQ” appears, this means that the Tone SQuelch system is active, which mutesyour VXA-710’s receiver until it receives a call from another radio sending out amatching CTCSS tone. This can help keep your radio quiet until a specific call isreceived, which may be helpful while operating in congested areas. When you have made your selection of the CTCSS tone mode, press the [SEL(SET)]key momentarily, then rotate the DIAL selector knob one click clockwise to select MenuItem (TONE Set). This Menu selection allows setting of the CTCSS tone frequency to beused. Press the [SEL(SET)] key to enable the adjustment of the CTCSS frequency.
