VX-8GR OPERATING MANUAL 13Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the manyfeatures of the VX-8GR. I know you’re anxious to get on the air, but I en-courage you to read the “Operation” section of this manual as thoroughly aspossible, so you’ll get the most out of this fantastic new transceiver. Now. . .let’s getoperating!SWITCHING POWER ON AND OFF1. Be sure the battery pack is installed, and that it is fully charged. Connect the antennato the top panel ANTENNA jack.2. Press and hold in the p(PWR) switch (on the left sideof the front panel) for 2 seconds. Two beeps will be heardwhen the switch has been held long enough. The open-ing message will appear briefly on the display, then thefrequency display will appear. After another two sec-onds, the receive-mode Battery Saver function will be-come active, unless you have disabled it (see page xx).3. To turn the VX-8GR off, press and hold in the p(PWR) switch again for 2 seconds.If you don’t hear the two “Beep” tones when the radio comes on, the Beepermay have been disabled via the Menu system. See page 27, which tells youhow to reactivate the Beeper.ADJUSTING THE VOLUME LEVELRotate the DIAL knob while pressing and holding the gkey to set the desired audio level. Clockwise rotation in-creases the volume level.1) The Volume level may be set on the“A-Band” and “B-Band” separately.2) You may set the Audio Output Level to theSpeaker, and the Earphone Output Level individually. The“SP VOLUME” notation appears in the S- & PO meter area while adjusting the SpeakerOutput Level. The “HP VOLUME” notation appears in the S- & PO meter area whileadjusting the Earphone Output Level.3) Pressing the f key followed by the g key, the DIAL knob function changes to theVolume Level adjustment instead of the frequency control. In this case, the “VolumeLevel Indicator” on the display blinks. Pressing the f key followed by the g keyagain, returns the DIAL knob function to the frequency control. You may also changethe g key function via Set Mode Item 99: VOLUME MODE. See page xx for details.OPERATIONFCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL14OPERATIONSQUELCH ADJUSTMENTThe VX-8GR’s Squelch system allows you to mute the background noise when no signalis being received. Not only does the Squelch system make “standby” operation morepleasant, it also significantly reduces battery current consumption.The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broad-cast) modes.1. Press the f key, then press the e key on the leftside of the radio. This provides a “Short-cut” to SetMode Item 85: SQL LEVEL85: SQL LEVEL85: SQL LEVEL85: SQL LEVEL85: SQL LEVEL.2. Now, rotate the DIAL knob to the point where the back-ground noise is just silenced (typically at a setting ofabout “3” or “4” on the scale); this is the point of maxi-mum sensitivity to weak signals.3. When you are satisfied with the Squelch threshold setting,press the PTT key briefly to save the new setting and exit tonormal operation.4. You may also adjust the Squelch setting by using the “Set”(Menu) mode. See page xx for details.1) The Squelch level may be set on the “Main” and “Sub” bands separately.2) If you’re operating in an area of high RF pollution, you may need toconsider “Tone Squelch” operation using the built-in CTCSS Decoder. Thisfeature will keep your radio quiet until a call is received from a station sending a carrierwhich contains a matching (sub audible) CTCSS tone. Or if your friends have radiosequipped with DCS (Digital Coded Squelch) like your VX-8GR, try using that mode forsilent monitoring of busy channels.24-HOUR CLOCKThe VX-8GR has a 24-hour clock with a calendar which covers all dates fromJanuary 1, 2000 through December 31, 2099.

VX-8GR OPERATING MANUAL 15SELECTING THE OPERATING BANDIn the factory default configuration, the VX-8GR operates in the “Dual Receive” mode.During Dual Receive operation, the “A-Band” frequency will be displayed on the upperpart of the LCD, and the “B-Band” frequency will be displayed on the lower part. The“Operating” band (the band on which transmission and band/frequency changes are pos-sible) is shown in large characters, and “Receive only” band is shown in small characters.Press the a key briefly to engage the “A-Band” fre-quency as the “Operating” band. Alternatively, press theb key briefly to engage the “B-Band” frequency, as de-scribed previously.Press and hold in the a or b key for 1/2 seconds toswitch to Mono Band Operation. During Mono band op-eration, you may change the display between “double-sizecharacter” and “large character” by pressing the a/b key.OPERATIONFCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL16OPERATIONSELECTING THE FREQUENCY BANDThe VX-8GR covers an incred-ibly wide frequency range, overwhich a number of different op-erating modes are used. There-fore, the VX-8GR’s frequencycoverage has been divided intodifferent operating bands. Eachband has its own preset channelsteps and operating modes. You can change the channel steps and operating modes later, ifyou like (see page xx).TO CHANGE OPERATING BANDS1. Press the B key repeatedly. You will see the LCDindication change to a higher frequency band each timeyou press the B key. A Band Number according tothe receiving frequency is also displayed.2. If you wish to move the operating band selection down-ward (toward lower frequencies), press the f keyfirst, then press the B key.3. The VX-8DR uses a dual VFO system (described previously). To switch TX/RX op-eration from the “VFO-A” to the “VFO-B” instantly, press the b key briefly. Pressingthe a key will return TX/RX operation to “VFO-A”. The frequency band shown in“Large” characters is the band on which transmission is possible; the band shown in“Small” characters may only be used for reception.4. Once you have selected the desired band, you may initiate manual tuning (or scan-ning). See the discussions on the next page.If desired, you may omit (skip) one or more bands from the band selectionloop for faster recall of your favorite operating bands.

VX-8GR OPERATING MANUAL 17FREQUENCY NAVIGATIONThe VX-8GR will initially be operating in the “VFO” mode, as just described. This is a fre-quency step system which allows free tuning throughout the currently-selected operating band.Three basic frequency navigation methods are available on the VX-8GR:1) TUNING DIALRotation of the DIAL knob allows tuning in the pre-pro-grammed steps established for the current operating band.Clockwise rotation of the DIAL knob causes the VX-8GRto be tuned toward a higher frequency, while counter-clock-wise rotation will lower the operating frequency.If you press the f key briefly, then rotate the DIAL knob,frequency steps of 1 MHz will be selected. This feature isextremely useful for making rapid frequency excursions over the wide tuning range of theVX-8GR.2) DIRECT KEYPAD FREQUENCY ENTRYThe desired operating frequency may be entered directly from the keypad.The operating mode will automatically be set once the new frequency is entered via thekeypad.To enter a frequency from the keypad, just press the numbered digits on the keypad in theproper sequence. There is no “Decimal point” key on the VX-8GR. However, there is a short-cut for frequencies ending in zero - press the c key after the last non-zero digit.Examples:To enter 146.520 MHz, press 146520To enter 430.000MHz, press 43cOPERATIONSub Band OperationWhen press the key followed by the key, you can cause the controls(except the TX function) to act on the “Sub” band. Whenthe Sub Band operation is activated, the Main band’s“Frequency Control” icon will blinks. After making con-trol to the Sub band, press the key followed by the key to return control to the “Main” band.FCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL183) SCANNINGFrom the VFO mode, press and hold in the B key for one second, and while stillholding in the B key, rotate the DIAL knob to selectthe bandwidth for the VFO scanner. Release the B keyto begin scanning toward a higher frequency. The scannerwill stop when it receives a signal strong enough to breakthrough the Squelch threshold. The VX-8GR will then holdon that frequency according to the setting of the “RESUMERESUMERESUMERESUMERESUME”mode (Menu Item 77: SCAN RESUME77: SCAN RESUME77: SCAN RESUME77: SCAN RESUME77: SCAN RESUME).If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of ahigher frequency), just rotate the DIAL knob one click in the counter-clockwise directionwhile the VX-8GR is scanning. The scanning direction will be reversed. To revert toscanning toward a higher frequency once more, rotate the DIAL knob one click clock-wise.Press the PTT switch briefly to cancel the scanning. See page xx for more details regard-ing Scan Operation.OPERATIONFREQUENCY NAVIGATIONDual Receive NoticeThe VX-8GR may receive very strong signals on the Image frequency, and/or thereceiver sensitivity may be somewhat reduced by the combination of the “A-Band”and “B-Band” frequencies while Dual Receive operation is engaged.If you experience interference that you suspect may be coming in via an “Image”path, you may calculate the possible frequencies using the formulas below. Thisinformation may be used in the design of effective countermeasures such as traps,etc.9.8304 MHz x n11.7 MHz x n(n is an integer: 1, 2, 3, …)4.9152 MHz x n6.1440 MHz x n“A-Band” Freq. = (“B-Band” Freq. ± 46.35 MHz) x n“B-Band” Freq. = (“A-Band” Freq. ± 47.25 MHz) x n (@ “A-Band” = NFM)“B-Band” Freq. = (“A-Band” Freq. ± 45.8 MHz) x n (@ “A-Band” = WFM)FCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL 19TRANSMISSIONOnce you have set up an appropriate frequency inside one of the dual amateur bands onwhich the VX-8GR can transmit (144 MHz or 430 MHz), you’re ready to transmit. Theseare the most basic steps; more advanced aspects of transmitter operation will be discussedlater.1. To transmit, press the PTT switch, and speak into thefront panel microphone (located in the upper right-handcorner of the speaker grille) in a normal voice level.The LED of the “A” or “B” which is designated the“Main” band will glow red during transmission.2. To return to the receive mode, release the PTT switch.3. During transmission, the relative power level will beindicated on the LCD. Additionally, the “L1”, “L2”, “L3”,or “HI” icon will appear at the left side of the PO meter,corresponding with the “Power” Level setting.1) If you’re just talking to friends in the immediatearea, you’ll get much longer battery life by switching to Low Power opera-tion. To do this, press the f key, then press the d key so that the “LowPower” icon appears at the bottom of the display. And don’t forget: always have anantenna connected when you transmit.2) Transmission is not possible on “Sub” band and any operating bands other than the144 MHz and 430 MHz bands on the “Main” band.3) Never transmit without having an antenna connected.CHANGING THE TRANSMITTER POWER LEVELYou can select between a total of four transmitter power levels on your VX-8GR. Theexact power output will vary somewhat, depending on the voltage supplied to the trans-ceiver. With the standard FNB-101LI Battery Pack and external DC source, the poweroutput levels available are: “L1”, “L2”, “L3”, or “HI”To change the power level:1. The default setting for the power output is “High;” inthis configuration, the display shows the “HI” icon.Pressing the f key, followed by the d key, causesthe power level “L1”, “L2”, or “L3” to appear.2. Press the f key, followed by the d key (repeat-edly, if necessary) to make the “HI” icon appear andrestore “High Power” operation.OPERATIONFCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL20OPERATION1) The VX-8GR is smart! You can set up Low power on one band (like UHF),while leaving VHF on High power, and the radio will remember the differentsettings on each band. And whenyou store memories, you can store High andLow power settings separately in eachmemory, so you don’t waste battery powerwhen using very close-in repeaters!2) When you are operating on one of the Lowpower settings, you can press the key, then press the PTT switch, to cause the VX-8GR to transmit (temporarily) on High power. After one transmission, the power levelwill revert to the previously-selected Low power setting.TRANSMISSIONFNB-101LI/-102LI or EXT DC (7.4 V)HI: 5.0 W,L3: 2.5 W,L2: 1.0 W,L1: 0.05 WTRANSMIT POWERFBA-39(w/Fresh Batteries)L2: 1.0 W,L1: 0.05 WFCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL 29CTCSS OPERATIONMany repeater systems require that a very-low-frequency audio tone be superimposed onyour FM carrier in order to activate the repeater. This helps prevent false activation of therepeater by radar or spurious signals from other transmitters. This tone system, called“CTCSS” (Continuous Tone Coded Squelch System), is included in your VX-8GR, and isvery easy to activate.CTCSS setup involves two actions: setting the Tone Frequency and then set-ting the Tone Mode. These functions are set up using Set Mode Items 88:SQL TYP and 91: TONE FREQUENCY.1. Press the f key, then press the M key. This provides a “Short-cut” to Set ModeItem 88: SQL TYPE88: SQL TYPE88: SQL TYPE88: SQL TYPE88: SQL TYPE.2. Rotate the DIAL knob so that “TONETONETONETONETONE” appears on the dis-play. This activates the CTCSS Encoder.3. Rotation of the DIAL knob one more “click” in step “2”above will also activate the “TSQTSQTSQTSQTSQ” decode function. When “TSQTSQTSQTSQTSQ” is displayed, theTone Squelch system is active, which mutes your VX-8GR’s receiver until it receivesa call from another radio sending out a matching CTCSS tone. This can helpful in ahigh RF congested location by keeping your radio quiet until a call is received from aspecific station with a matching CTCSS tone.CTCSS/DCS/EPCS OPERATIONYou may notice an additional “DCSDCSDCSDCSDCS” indication appearing while you rotatethe DIAL knob in step 3 above.

VX-8GR OPERATING MANUAL32DCS CODE INVERSIONThe DCS system was first introduced in the commercial LMR (Land Mobile Radio) ser-vice, where it is now in widespread use. DCS is sometime referred to by its differentproprietary names, such as DPL® (Digital Private Line®, a registered trademark of Motorola,Inc.).DCS uses a codeword consisting of a 23-bit frame, transmitted (sub audible) at a data rateof 134.4 bps (bit/sec). Occasionally, signal inversion can result in the complement of acode being sent or received. This prevents the receiver’s squelch from opening with DCSenabled, as the decoded bit sequence would not match that selected for operation.Typical situations that might cause inversion to occur are:Connection of an external receiver preamplifier.Operating through a repeater.Connection of an external linear amplifier.Note that code inversion does not mean that any of the above listed equipment is defective!In certain amplifier configurations, the output signal (phase) is inverted from the input. Smallsignal or power amplifiers having an odd number (1, 3, 5, etc.) of amplification stages mayresult in inversion of a transmitted or received DCS code. While under most circumstancesthis should not occur (amplifier designs and industry standards take this into account), if youfind that your receiver squelch does not open when both you and the other station are using acommon DCS code, you or the other station (but not both) can try the following:1.

VX-8GR OPERATING MANUAL34TONE SEARCH SCANNINGIn operating situations where you don’t know the CTCSS or DCS tone being used byanother station, you can command the radio to listen to the incoming signal and scan insearch of the tone being used. Two things must be remembered in this regard:You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).Some repeaters do not pass the CTCSS tone; you may have to listen to the stationtransmitting on the repeater uplink (input) frequency in order to allow Tone SearchScanning to work.To scan for the tone in use:1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous dis-cussion). In the case of CTCSS,“TSQTSQTSQTSQTSQ” will appear on the display;in the case of DCS, “DCSDCSDCSDCSDCS” willappear on the display.2.

Press and hold in the B key, the “TONE SEARCHTONE SEARCHTONE SEARCHTONE SEARCHTONE SEARCH” notation will appear, releasethe B key to start scanning for the incoming CTCSS or DCS tone/code.4. When the radio detects the correct tone or code, it will halt on that tone/code, andaudio will be allowed to pass. Press the B key to lock in that tone/code, then pressthe 2 key to exit to normal operation.If the Tone Scan feature does not detect a tone or code, it will continue toscan indefinitely. When this happens, it may be that the other station is notsending any tone. You can press the PTT switch to halt the scan at any time.You can also press the e key during Tone Scanning to listen to the (muted) signal fromthe other station. When you release the e key, Tone Scanning will resume after about asecond.Tone Scanning works either in the VFO or Memory modes.CTCSS/DCS/EPCS OPERATIONFCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL 35CTCSS/DCS/EPCS OPERATIONEPCS (ENHANCED PAGING & CODE SQUELCH)The VX-8GR includes an Enhanced CTCSS tone encoder/decoder and a dedicated micro-processor providing paging and selective calling features. This allows you to place a callto a specific station (Paging), and to receive calls of your choice directed only to you(Code Squelch).The paging and code squelch systems use two pairs of (alternately switched) CTCSStones which are stored in the pager memories. Basically, your receiver remains silent untilit receives the CTCSS tone pair that matches those stored in the Receiving Pager Memory.The squelch then opens so the caller is heard, and the paging ringer immediately sounds,if activated. When you close the PTT switch to transmit, the CTCSS tone pair that isstored in the Transmitting Pager Memory will be transmitted automatically.On the paged radio, the Code Squelch will close automatically after the incoming pageends. Meanwhile, on the paging radio, the Enhanced Paging and Code Squelch systemwill be disabled after the PTT switch is released after the paging transmission. You mayre-activate the Enhanced Paging and Code Squelch system again.STORING THE CTCSS TONE PAIRS FOR EPCS OPERATION1. Press and hold the m key for one second to enter the Set Mode.2.

VX-8GR OPERATING MANUAL48MEMORY MODE (REGULAR MEMORY CHANNEL OPERATION)MASKING MEMORIESThere may be situations where you want to “Mask” memories so they are not visibleduring memory selection or scanning. For example, several memories used only in a cityyou visit infrequently may be stored, then “Masked” until you visit that city, at which timeyou can “Unmask” them for normal use (except for Memory Channel “1”).1. Press the c key, if needed, to enter the Memory Recall (“MR”) mode.2. Press and hold in the f key for 1/2 second, then rotatethe DIAL to select the memory channel to be “Masked”from view.3. Press the d key. The confirmation message (MR MASK?MR MASK?MR MASK?MR MASK?MR MASK?)will appear on the display. Press the d key once more,the display will revert to memory channel #1. If you rotatethe DIAL to the location you just “Masked,” you will ob-serve that it is now invisible.4. To Unmask the hidden memory, repeat the above procedure: press and hold in thef key for 1/2 second, rotate the DIAL to select the masked memory’s number, thenpress the d key to restore the memory channel’s data.Watch out! You can manually store data over a “Masked” memory, deletingprevious data, if you’re not careful. Use the “next available memory” stor-age technique to avoid over-writing a masked memory.FCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL54GENERALThe VX-8GR allows you to scan just the memory channels, the entire operating band, ora portion of that band. It will halt on signals encountered, so you can talk to the station(s)on that frequency, if you like.Scanning operation is basically the same in each of the above modes. Before you begin,take a moment to select the way in which you would like the scanner to resume scanningafter it halts on a signal.SETTING THE SCAN-RESUME TECHNIQUEThree options for the Scan-Resume mode are available:2.0sec - 10.0sec2.0sec - 10.0sec2.0sec - 10.0sec2.0sec - 10.0sec2.0sec - 10.0sec: In this mode, the scanner will halt on a signal it encounters, and willhold there for the selected resume time. If you do not take action todisable the scanner within that time period, the scanner will resumeeven if the station is still active.BUSYBUSYBUSYBUSYBUSY: In this mode, the scanner will halt on a signal it encounters. When thecarrier has dropped because the other station ceased transmission, thescanner will resume. In the case of constant-carrier signals like WeatherStation broadcasts, the scanner will likely remain on this frequencyindefinitely.

VX-8GR OPERATING MANUAL 59HOW TO SKIP (OMIT) A CHANNEL DURING MEMORY SCANAs mentioned previously, some continuous-carrier stations like a Weather Broadcast sta-tion will seriously impede scanner operation if you are using the “Carrier Drop” Scan-Resume mode, as the incoming signal will not pause long enough for the transceiver toresume scanning. Such channels may be “Skipped” during scanning, if you like:1. Recall the Memory Channel to be skipped during scanning.2. Press the f key, then press the 5 key to appear a small“” icon at the left of the frequency display. The currentMemory Channel will now be ignored (skipped) duringscanning (the “skipped” channel will, of course, still be ac-cessible via manual channel selection methods using the DIAL knob in the MemoryRecall (“MR”) mode, whether or not it is locked out of the scanning loop).To re-institute a channel into the scanning loop, press the f key followed by the 5key twice, to disappear the small “” icon from display.Note: You may notice a blinking “” icon while you perform above procedure. It indi-cates the “Preferential Memory Scan” channel, described in the next column.PREFERENTIAL MEMORY SCANThe VX-8GR also allows you to set up a “Preferential Scan List” of channels which youcan “flag” within the memory system. These channels are designated by a blinking “”icon when you have selected them, one by one, for the Preferential Scan List. When youinitiate memory scanning on a channel with the blinking “” icon appended, only thosechannels bearing the blinking “” icon will be scanned. If you initiate scanning on achannel which does not have the blinking “” icon appended, you will scan all channelsincluding those with the blinking “” icon appended.Here is the procedure for setting up and using the Preferential Scan List:1. Recall the Memory Channel which you wish to add to the Preferential Scan List.2. Press the f key followed by the 5 key until a blinkingsmall “” icon appears at the left of the frequency display.To clear the memory channel from the “Preferential Scan List”,press the f key followed by the 5 key to disappear theblinking small “” icon from display.SCANNINGMEMORY SCANNINGFCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL 83The ARTSTM feature uses DCS signaling to inform both parties when you and anotherARTSTM-equipped station are within communications range. This may be particularlyuseful during Search-and Rescue situations, where it is important to stay in contact withother members of your group.Both stations must set up their DCS codes to the same code number, then activate theirARTSTM feature using the command appropriate for their radio. Alert ringers may beactivated, if desired.Whenever you push the PTT, or every 25 (or 15) seconds afterARTSTM is activated, your radio will transmit a signal whichincludes a (subaudible) DCS signal for about 1 second. If theother radio is in range, the beeper will sound (if enabled) andthe display will show “IN RNGIN RNGIN RNGIN RNGIN RNG” as opposed to the out of rangedisplay “OUTRNGOUTRNGOUTRNGOUTRNGOUTRNG” in which ARTSTM operation begins.Whether you talk or not, the polling every 15 or 25 seconds willcontinue until you de-activate ARTSTM. Every 10 minutes, more-over, you can have your radio transmit your callsign via CW, to comply with identifica-tion requirements. When ARTSTM is de-activated, DCS will also be deactivated (if youwere not using it previously in non-ARTSTM operation).If you move out of range for more than one minute (four pollings), your radio will sensethat no signal has been received, three beeps will sound, and the display will revert to“OUTRNGOUTRNGOUTRNGOUTRNGOUTRNG”. If you move back into range, your radio will again beep, and the display willchange back to the “IN RNGIN RNGIN RNGIN RNGIN RNG” indication.During ARTSTM operation, your operating frequency will continue to be displayed, but nochanges may be made to it or other settings; you must terminate ARTSTM in order toresume normal operation. This is a safety feature designed to prevent accidental loss ofcontact due to channel change, etc.ARTSTM (AUTOMATIC RANGE TRANSPONDER SYSTEM)FCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL96EMERGENCY FEATUREEMERGENCY AUTOMATIC ID (EAI) FEATUREThe Emergency Automatic ID (EAI) feature can be used to aid in searching for personswho are incapacitated in disasters like earthquakes, especially search-and-rescue person-nel who may have become injured in a debris field. When using the EAI feature, a searchertransmits a unique command (CTCSS tone pair), which will automatically cause the in-jured party’s radio to transmit, so others may perform direction-finding and effect a res-cue. The incapacitated party may not be able to speak or even press the PTT switch. Thecallsign of the incapacitated person will also be transmitted, to assist the rescue team.If an emergency group is working in a dangerous area, all members should engage theEAI feature on their transceiver, so that others can assist a fallen team member, if neces-sary.The Emergency Automatic ID (EAI) Feature has two operating modes: (1) Interval modeand (2) Continuous mode.In the Interval mode (when the VX-8GR receives the CTCSS tone pair), the radio willautomatically transmit a brief (0.5 second) beep tone every 2.5 seconds until the EAItimer expiration.In the continuous mode, the radio will automatically transmit continuously (with maxi-mum microphone gain), until the EAI timer expiration.The EIA is activated when the CTCSS tone pair stored in the Receiving Pager Code Memory(configured via Set Mode Item 62: PAGE CODE-RX62: PAGE CODE-RX62: PAGE CODE-RX62: PAGE CODE-RX62: PAGE CODE-RX) is received for 5 seconds on thefrequency, which is stored in Memory Channel “EAIEAIEAIEAIEAI”. It is NOT necessary for the inca-pacitated person to press the PTT switch.If your call sign is stored in the radio and the CW identifier is enabled via Set Mode Item16: CW ID16: CW ID16: CW ID16: CW ID16: CW ID, the radio will transmit your callsign on the air when the EAI feature is firstactivated by the remote page, and every 10 minutes thereafter. The “callsign” ID can bechanged to any desired sequence of characters, such as a name. After sending the callsignor name, the radio will repeatedly transmit three tones for a user-defined period of time(between 1 and 30 minutes). The callsign or name will be transmitted every 10 minutes.The Emergency Automatic ID (EAI) Feature requires that you (1) store the CTCSS TonePair into the Receiving Pager Memory (see page xx for procedure), and (2) store thedesired UHF coordination frequency into Memory Channel “EAIEAIEAIEAIEAI” (see page 47 for proce-dure).FCC ID: K6620415X20 / IC:511B-20415X20
