8Indicators and Display Functions●Indicates that your radio has received a Selcall call. If the indicator is flash-ing, your radio received a call which you were unable to answer. Your radiomay be programmed to display your caller's identity.●Indicates that your radio is ready for you to select a status code relating toyour current activity. You may use the Up and Down ( /) scrollkeys to choose a status code or description from a list.●Indicates that your radio is ready for you to enter information to enable it toselect a new channel. You may use the Up and Down ( /) scrollkeys to choose from a list, the Alphanumeric ( ) key to enter a label,or the number keys. If the indicator is flashing, the current channel is inRepeater Talkaround mode.●Indicates that you can enter information, such as a channel label, from thekeypad, using letters or numbers.●If this indicator is on continuously, the signalling mute (if active) is open. Thismay be because either the microphone is off-hook, or you have pressed theMonitor ( ) key. If the indicator is continually flashing, the Monitor keyhas been pressed for long enough to open the RF squelch.Note: When the radio is operating normally, this indicator is off.●Indicates the state of the auxiliary options switch. Depending upon the pro-grammed configuration of the auxiliary options switch, this indicator may beeither on continuously or off continuously, or may only come on while theAuxiliary ( ) key is pressed down.●Indicates that you can change the user programmable options. The displaywindow shows the option last viewed. You may use the Up and Down (/) scroll keys to move through the options, then select one with theEnter ( ) key.●Indicates you have pressed the Enter ( ) key.When these indicators are all off, the radio is in DTMF mode. It can nowtransmit DTMF tones, entered via the keypad.STATChFnCALL, STATUS, CHAN-NEL, ALPHANUMERIC &FUNCTION indicators alloff
9Display WindowThe LCD display window provides you with direct visual access to information and messages about thestatus of your calls and your radio.Display Window IndicatorsBUSYBusy - This appears whenever there is activity on you current channel. If thesignalling mute on your radio is closed (see the function), you maynot hear the traffic until you lift your microphone off-hook.TXTransmit - Your radio is transmitting. This message is displayed when youpress the PTT key. It should also come on briefly when your radio makes aSelcall or DTMF call.SCANScan - Your radio is sampling each of a group of channels for any activity.When it detects activity, it pauses on that channel for as long as the channelcarries traffic and then resume scanning.WAITWait - The channel you are using is busy and your call has been deferred.The radio gives you an alerting signal to indicate that the channel is nowfree.Scrolling available - You are now able to use the Up and Down ( /) scroll keys to move through a list of choices. Having found an ap-propriate choice with the keys, push the Enter ( ) key to select.STAT ChFnαTX SCANBUSYT2000IIWAIT
10Standard OperationsSwitching the Radio On and OffSwitching the Radio OnSwitch the radio on by rotating the volume knob clockwise to about one third of its maximum setting.The control head display then shows a power-up message.When first switched on, the radio resumes operation on the same channel as when it was last switchedoff.Press and hold the Monitor ( ) key until the indicator flashes. The radio then emits two shorttones. Depress the key briefly to return the radio to the quiet state. The radio then emits a short tone.You may need to finally set the volume level when you receive your first call.Switching the Radio OffSwitch the radio off by rotating the volume knob anticlockwise, to its primary position.The T2020IIretains some settings that are used when it is switched on again.Selecting a Channel or a GroupSelecting a ChannelWhen first switched on, the radio resumes operation on the same channel as when it was last switchedoff.To check the current channel:●Select Channel mode by pressing the Channel (Ch) key, and the current channel nameappears in the display window.To select a new channel:●Press the Up and Down ( /) scroll keys on the keypad to move through the list of theavailable channels, until the display shows the identity of the required channel, or●Use the numeric keypad to enter a new channel number, then press the Enter ( ) key, or●Use the alphanumeric keypad to enter an alphanumeric label, then press the Enter ( ) keyto initiate the call.
11STATChFnαBUSYT2000Selecting a GroupA group is simply a collection of channels grouped together for scanning or voting. Select a group thesame way as a channel.Receiving a CallThe T2020IIremains muted until another user makes a call. Listen for your call-sign when you hearactivity, and reply promptly by identifying yourself (for example ‘Mobile-9 receiving’).The BUSY indicator in the display appears whenever there is any activity on the channel. Your radiomay only unmute the speaker for some of this activity, depending on which signalling options are fittedto your radio. Consult your Tait dealer about the signalling options available.Using the Monitor KeyThe Monitor ( ) key enables you to monitor a channel for other users, regardless of the mutingcontrols programmed into your radio. There are three types of muting control which may screen yourcalls:RF squelchPermits reception only if the radio's signals exceed a preset threshold. Thisensures that only intelligible signals are audible.CTCSS or DCS mutePermits reception only if a signal carries an inaudible tone or code specific toyour fleet or group.Selcall mutePermits reception only if the signal carries a special audible tone sequenceat the beginning of the transmission.Note:The RF Squelch is always programmed to operate in your radio, but the CTCSS, DCS orSelcall mutes are optional, depending on the way your radio is programmed.
12The Monitor key may be programmed to override one or more of the mutes. Occasionally, you may findthe message you are receiving is still intelligible, but is being cut off periodically by the RF squelch. Inthis case, you can force the radio to leave the RF squelch open continuously.The most common configuration is as follows:●Press the Monitor key briefly (less than one second) to override CTCSS/DCS or Selcall signal-ling mute. (If hookswitch monitoring is programmed, lifting the microphone off-hook has the sameeffect.)●To also override the RF squelch, hold the Monitor key for more than one second, until the radiosounds two short tones, beep beep, and the MONITOR indicator flashes. Press again to restore.Your T2020IImay be fitted with the ability to hush (mute) another device, such as a car stereo, so that yourspeech is clearly audible to other users when you transmit a call. Consult your Tait dealer to see if thisfacility is active on your radio.Making a CallSelect the desired channel, as previously described, for the party you wish to contact. If the BUSYindicator is on, the channel is busy and you must wait until it is free, before proceeding. If you attempt totransmit anyway, the WAIT indicator appears in the display, and your attempt is deferred. The radiosounds an alerting tone as soon as the channel becomes free.●Lift the microphone off-hook and listen to check that no-one else is using the channel. You mayalso have to press the Monitor ( ) key briefly, depending on the options fitted to your radio.●Hold the microphone about 5cm from your mouth and press the Press-To-Talk (PTT) key,located on the side of the microphone (see Figure 1). Speak clearly into the microphone, iden-tifying yourself by your call sign, and the person you wish to contact (for example - ‘Mobile-9 toBase’). Release the PTT key when you have finished talking (see Figure 2).Figure 1 Figure 2
13Transmit TimerYour T2020IIis fitted with a preprogrammed timer to limit the maximum length of transmissions.When the time limit is reached, the radio sounds a three tone warning, and transmission is termi-nated.Economy ModeThe T2020IIincorporates an Economy mode which conserves battery power by turning off someinternal circuitry, and dimming the control head back-lighting. This occurs after a predetermined periodof inactivity.When Economy mode is active, the display backlighting dims or switches off.Operating any of the control head controls, or the PTT key, restores the radio to full activity immedi-ately.Scanning ChannelsYour T2020IIcan be programmed with the scanning facility, which enables it to sequentially monitor anumber of channels, pausing its search when it detects activity on a channel. To change the channelsincluded in your scan group, refer to ‘User Programmable Scan’.To Activate ScanningSet the radio scanning through a list of preprogrammed channels, as follows:●Ensure the microphone is placed on its hook. (Your radio may be programmed to scan when-ever the microphone is off-hook. Consult your Tait dealer for more information on this feature.)●Select the appropriate scan group in the same way as selecting a channel (see ‘Selecting aChannel’). The SCAN indicator appears in the display window, and scanning commences.STAT ChFnαSCANT2000II
14The T2020IInow repeatedly scans through all programmed channels, searching for activity. Whenactivity is detected on a channel, the scan is halted, and the display window shows the active channel’sname. (If signalling options are active in the radio, only activity with valid signalling tones halts thescanning.) The radio pauses and unmutes on that channel, as long as the traffic remains, and theSCAN indicator flashes. Scanning resumes after a short delay, once the traffic disappears.You may change channel if you wish, but this cancels Scan mode. Otherwise, converse in the normalmanner and, when finished, place the microphone back on its hook to restart the scan.To Stop ScanningScan mode is cancelled by selecting any non-scanning channel. The SCAN indicator then disappearsfrom the display window.Making a CallIf you wish to make a call when the radio is in Scan mode, you may lift the microphone off-hook at anytime to suspend scanning. If the radio has halted scanning to monitor the traffic on a channel, it remainson that channel when you lift the microphone off-hook. If the radio has found no traffic (i.e. has nothalted), it reverts to the preprogrammed home-channel.Using Selcall (Selcall Option Fitted)By using Selective Calling (Selcall), you can make calls to specific individuals or groups, on particularchannels. To use Selcall, your T2020IImust be fitted with a Selcall module, and each channel prepro-grammed to provide its own Selcall identity.Making a Selcall CallCall another party using Selcall, as follows:1. Check that the radio is on the correct channel and that the channel is clear before attempting tomake the call.2. Select the appropriate channel for the party you wish to contact (see ‘Selecting a Channel’).3. If your radio is programmed with the ability to make a ‘one touch’ call to one other user (usuallyyour base or despatcher), press the Call ( ) key for about one second. The TX indicatorappears in the display briefly, and your radio sounds a short beep as the call is transmitted.

If your radio is programmed with the ability to call other users with Selcall on your channel, pressthe Call ( ) key briefly to activate Selcall mode. Use your keypad to enter the call code forthe other user. Each digit appears in the display as it is entered. When you have entered all of thedigits, press the Enter ( ) key or the Star ( ) key, to send the call.Example: You wish to call another user on the current channel (REGION 2), with the number 37515.The sequence of keystrokes, and the corresponding display characters that appear, is as follows:5. When the party you called replies, lift the microphone off-hook and press the PTT key to converse.
16STATChFnαT2000II6. After the call is sent, you may hear an acknowledging tone, beep, or series of tones from the otheruser’s radio, indicating that your call has been received. If you do not hear a tone, either the otheruser's radio is incapable of generating the acknowledging tone, or it is off, or they are out of rangeof your call.Your T2020IImay be programmed to display the status of the called unit, as follows:Status displayed Explanation‘-NO ACK-’No acknowledge sequence was detected.‘NO STAT’An acknowledge sequence was detected but no status information was de-coded.Status message An acknowledge sequence was detected and the decoded status numbercan be identified.Status number An acknowledge sequence was detected and the decoded status numbercannot be identified.If any control head activity is detected before any of the above messages are displayed, the acknowl-edge sequence is no longer expected, and messages will therefore no longer be displayed.Group CallsIf you wish to call a group of other users, you may do so by dialling the digits common to all members ofthe group and then using the # character as a substitute for all the remaining digits. If you are not surewhether this facility has been programmed into your radio, consult your Tait dealer.
17STATChFnαT2000II7PQRS3DEFTXPress key Characters displayed ExplanationCurrent channelLast number called1st digit of the new number2nd digit of the new numberGroup wild card characterCall placed to all 37??? usersExample: You wish to call a group of users on the current channel (REGION2) with numbers which allbegin with 37, and have three more digits. After you have selected channel REGION 2, the sequence ofkeystrokes, and the corresponding display characters that appear, is as follows:When the group call has been sent, there is no acknowledging tone from any of the other users. Wait afew seconds after the TX indicator in the display window disappears and then broadcast your message.Phrase your message in such a way that it requires no acknowledgement, since the other users cannotall reply at once.Receiving a Selcall CallWhen you receive a Selcall call, the CALL indicator flashes and a ringing tone (similar to that of atelephone) sounds from the speaker.Note:Your T2020IImay be programmed to display the call-er’s identity when you receive a call. Consult your Taitdealer for more information on this feature.●To answer the call, lift the microphone off-hook and identifyyourself. As soon as you operate the PTT key, the ringingtone stops.●If you do not answer the call within a short time, the ringing tonestops. The radio may then switch on another alerting device(e.g. the horn in your car) to attract your attention.
18●Your T2020IImay be programmed to queue incoming calls. If this feature is enabled, the caller’sidentity is put in the queue after the ringing stops. All other call indicators are cleared when thereceived call has been queued. (Refer to the section ‘Call Queuing’ for more information.)●If the call was not queued and you are still unable to answer the call, the radio indicates that a callwas received in your absence by leaving the CALL indicator flashing.●If you do not wish to answer a call, the ringing may be cancelled at any time by pressing any of thecontrol head keys. (The function associated with the key you press will not be invoked.) Note thatif the caller’s identity was displayed and the call was still not answered, pressing the Enter ( )key clears the call and initiates an immediate call-back to the caller.●If you are one of the recipients of a group call, your radio only sounds a single sequence of theringing tone, burr burr. The caller then broadcasts a message to all members of your group.
19Advanced User OperationsMost of the special features detailed below must be enabled during programming of the T2020II. Con-sult your Tait dealer to find out which of these features have been enabled in your radio.Alphanumeric Entry ModeThe T2020IIcontains a number of memory locations which are able to be accessed with an alphanu-meric entry or label, from the keypad. The alphanumeric label may be the same as a channel name orit may be a quite separate word, person’s name or acronym which helps you find the appropriatememory location. Each location contains information which selects a channel scan group, makes aSelcall or DTMF call or selects a new Selcall status code.Select a memory location by its alphanumeric label, as follows:1. Press the Alphanumeric ( ) key to enter Alphanumeric mode.2. Locate the desired label by using the Up and Down ( /) keys to scroll through thelist until the label is displayed. Alternatively, enter the label associated with the party you want,using the keypad.A star appears in the display as you type each character, until you have entered enough for theradio to recognise the label. When it does, it displays the label in full. Pressing the Enter keycauses any instructions (channel selection, send call, and so on) contained in the memorylocation to be carried out.3. Press the Channel (Ch) key and the display changes from the label to the channel name. (Theradio may be programmed to return to the channel name display after a short while, anyway.)Example: You wish to call your BASE, which monitors a channel called REGION2 and has the Selcallcode 24624. The sequence of keystrokes, and the corresponding display characters that appear, is asfollows:
20Last label enteredUnable to determine new labelExplanationUnable to determine new labelNew label identifiedCharacters displayedChannel REGION2 selected andSelcall code transmittedChannel for BASE displayedPress key7PQRS2ABC2ABC2ABCChSTAT ChFnαT2000IIRepeater TalkaroundRepeater Talkaround is a programmable option that allows your T2020IIto bypass the repeater, andtransmit and receive calls directly on the repeater transmit frequency. This feature can be used, forexample, when you are out of range of the repeater.1. Press the Channel (Ch) key for longer than 1 second.The CHANNEL indicator should now be flashing, indicating that the T2020IIis now in RepeaterTalkaround mode.2. Select the appropriate channel and proceed with your call in the usual manner.
21Sending DTMF Tones (DTMF Option Fitted)The keypad on the T2020IImay also send Dual Tone Multiple Frequency (DTMF) tones (consult yourTait dealer to see if this option is fitted to your radio). This gives you the ability to dial telephone num-bers, if your radio network has an interconnection to the Public Switched Telephone Network (PSTN),or to send tones as control codes to remote devices.1. To enter DTMF mode, observe which of the mode key indicators is currently illuminated (i.e. Call,Status, Channel, Alphanumeric or Function) and push that key to deactivate the function. Thisleaves the radio in DTMF mode, with the last number dialled showing in the display window.2. Press the Enter ( ) key and the radio redials the number in the display.3. Dialling a new number may be done digit by digit or as a complete number, as follows:- To transmit the tone with each key-press (i.e. ‘live’), press the PTT key on the microphone as youdial. (Your radio may be programmed so that you need only press the number key.) The TXindicator appears in the display as you dial.- To set up a complete sequence of digits, push each number key in turn without pressing the PTTkey (although your radio may be programmed to transmit the tones live, anyway). Each numberappears in the display.- When the sequence is complete, press the Enter key to transmit the digits. Even if the digits havebeen transmitted live, they are now retransmitted as a group.In this mode, the transmission time of each digit is set by the radio, and is usually shorter andmore efficient than sending the tones live.4. Pressing any of the keys on the keypad causes the corresponding DTMF tone to sound, but thisdoes not indicate whether or not the tone has actually been transmitted. Watch your radio’s dis-play to see if the TX indicator appears (without the PTT key pressed).5. To access special DTMF tones A to D, your radio may be programmed to use the PTT key as a shiftkey, to alter the function of some of the keypad keys, as follows:- PTT + 2ABC gives DTMF tone A- PTT + 5JKL gives DTMF tone B- PTT + 8TUV gives DTMF tone C- PTT + 0 gives DTMF tone D
22STAT ChFnαT2000IIUser Programmable ScanDepending on how your T2020IIis programmed, you may be able to change the channels that areincluded in your scan group. Existing channels can be removed and new channels can be added, asrequired.Edit the user programmable scan group, as follows:1. Press the Function (Fn) key.2. Scroll through the items in the display window using the Upand Down ( /) keys, until ‘PROG GRP’ is dis-played.3. Press the Enter ( ) key. The name of the group isdisplayed, and the top row of indicators is illuminated.4. Press the Enter key a second time to start the editing thegroup.5. Press the Up and Down keys to scroll through all the available channels. The SCAN indicatorindicates those channels that are included in the user programmable scan group, and a flashingSCAN indicator indicates the home channel.6. To add or delete a channel from the scan group, select the required channel and then press theEnter key.Note:A scan group must contain 2 to 16 channels.The home channel is defined by selecting a channel and then holding the Enter key for longer than 1second. The SCAN indicator then flashes.Note:You can only delete a normal channel from the scan group. If the home channel is to be deletedfrom the scan group, you first have to define another channel as home channel and then deletethe original home channel.7. Once the group editing is complete, press the Function key to return to the Function menu.8. Press a mode key to switch to another mode, if desired. Alternatively, the inactivity timer returnsthe radio to the normal operating mode if no operator activity has been detected for 10 seconds.
23STATChFnαT2000IICall Queuing (Selcall Option Fitted)Your T2020IIcan be preprogrammed to queue incoming calls. This feature enables the storage of upto 10 caller identities.Call Queue Not EmptyWhenever there is an entry in the call queue, the Function menu is automatically active, with ‘CALLQUE’ appearing in the display window as the current item. This means that the radio always reverts tothe Function menu after a period of no-user activity, as long as there is a call queue entry. In addition,the FUNCTION indicator flashes whenever the Function menu is active.Accessing the Call QueueThe Call queue can be accessed through the Function menu. This is the same mode that is used to alteruser options.1. Press the Function (Fn) key. The item last viewed while in this mode appears in the displaywindow.2. Scroll through the displayed items using the Up and Down ( /) keys, and select‘CALL QUE’ using the Enter ( ) key.You are now in Call Queue Entry mode.Note:Call Queue Entry mode can only be accessed if there are entries in the call queue.In Call Queue Entry mode, the display window shows the current entry number, and the totalnumber of entries in the list. An example of the display would be ‘CL 01/02’, indicating that thecurrent entry is entry number one, with a total of two entries in the queue. Use the Up and Downkeys to scroll through the list of entries, and the Zero (0) key to delete an entry from thequeue.
243. Press the Enter key, and the caller identity of the entry in the display window appears. Again, youcan use the Up and Down keys to scroll through the list of entries, and the Zero key to delete theentry from the queue.4. Press the Enter key again when the caller identity of the entry is being displayed, and call-back isinitiated. The entry is then automatically removed from the queue. Note that the call-back se-quence is based on the caller identity.Exiting the Call QueueExit Call Queue Entry mode by pressing any mode key, including the Function (Fn) key.The radio automatically exits from Call Queue Entry mode, and reverts to the Function menu, if the lastentry in the call queue is deleted. This can be done either by using the Zero key, or making a call-back.Queuing CallsThe caller identity and the channel of the received call is put in the call queue when:●The internal alert (ringing) of the received call stops●Another call is received before the previous one is queued.Note:After the incoming call has been queued, it is automatically cleared or answered, and the radioresumes what it was doing prior to receiving the call. This includes the resumption of scanning,if the radio was scanning prior to receiving the call.Call Queue FullWhenever the queue is full, the radio continues to receive calls, but does not resume what it was doingprior to receiving the call (e.g. scanning). This allows calls to be received only on the held channel.Subsequent calls that are received overwrite the information about the previous call.
25Changing the Selcall Status Code (Selcall Option Fitted)If your radio is fitted with Selcall, you may also be able to choose from a number of activity codes to besent with each call you make, indicating your current status. Each code’s description and number (0 to99) is set when the radio is programmed. Typical descriptions might be ‘AT LUNCH’, ‘EN ROUTE’, andso on.1. Press the Status (STAT) key to enter Status mode. How status codes are displayed by yourradio depends on which status display function is active (see the later section, ‘Altering UserOptions’).2. If ‘normal display’ (STAT NRM) is active, the complete eight character word for the currentlyselected status is displayed.Scroll through the choices using the Up and Down ( /) keys, until you find oneappropriate for your present activity. Alternatively, type the number for your new status directlyusing the keypad. The new status description appears in the display (you may need to press theEnter ( ) key first).3. If ‘fixed display’ (STAT FIX) is active, your own status is displayed as a code at the right of thedisplay (along with the channel name, truncated to six characters).Scroll through the choices using the Up and Down keys. Again, you may enter the number foryour new status directly using the keypad. The new status code appears in the display (you mayneed to press the Enter key first).4. The status code is sent when your radio acknowledges another user’s call.Diverting a Received Call (Selcall Option Fitted)This feature enables the radio to be put into Call Diversion mode, where any valid incoming Selcallsequence causes the radio to transmit another user defined Selcall or DTMF sequence on the pro-grammed call diversion channel. The sequence (number) to be transmitted and the call type (Selcall orDTMF) can be entered by the user while in Call Diversion Setup mode.Activating Call Diversion Setup ModeCall Diversion Setup mode can be accessed through the Function menu.1. Press the Function (Fn) key. The item last viewed while in this mode appears in the displaywindow.2. Scroll through the displayed items using the Up and Down ( /) keys, and select‘DIVERT’, using the Enter ( ) key.The call diversion setup process has now been initiated.
26STAT ChFnαT2000II3. On entry into the setup process, the display flashes the last selected diversion call type, eitherSelcall or DTMF. Use the Up and Down keys to toggle between the two options. Note that if theDTMF option has not been fitted on the radio, the DTMF call type will not be an option.4. Press the Enter key to confirm the call type selected, and the last selected sequence is displayed,if still valid. If the last selected sequence is no longer valid, the default sequence is displayed.5. If another sequence is required, use the numeric keypad to enter the new diversion sequence.Note that the correct sequence length must be entered (consult your Tait dealer for more informa-tion on this).6. Press the Enter key to confirm the diversion sequence and to put the radio into Call Diversionmode.Exiting Call Diversion ModeAt any stage of the call diversion setup process, any mode key-press initialises that mode, and there-fore takes the radio out of the Call Diversion Setup process or Call Diversion mode. This includes theFunction (Fn) key.Receiving a Call During Call DiversionWhen a standard incoming call is received by the radio in Call Diversion mode, the programmed auto-acknowledge sequence is transmitted, as for a normal call. However the programmed diversion statusis transmitted instead of the normal acknowledge status, to inform the caller that the call has beendiverted.The radio then switches to the programmed call diversion channel and transmits the sequence that hasbeen set up for the call diversion, without indicating to the user that an incoming call has been received(no ringing). After executing the diversion transmission, the radio reverts to the channel it was on priorto the call diversion.
27Making a Call to a Radio In Diversion ModeYour T2020IIcan be programmed to respond to a diversion status report when making a call. When itdetects the diversion status in the acknowledge from the radio it has called, it displays ‘DIVERT’, toindicate that the call has been diverted. It then proceeds to switch to the programmed diversion chan-nel.Emergency Operation (Selcall Option Fitted)Your T2020IIcan be set to make emergency calls to a preprogrammed party (usually your base oryour despatcher). To use this capability, the radio must be fitted with the Selcall option, and be con-nected to a hidden emergency switch. Alternatively, the Auxiliary ( ) key on the control head maybe preprogrammed to send an emergency call.1. To send an emergency call, operate the hidden switch, or press the Auxiliary ( ) key. Thereis no change in the T2020II control head indicators, but the radio sends a Selcall emergencycode to the preprogrammed party every few seconds, until it receives an acknowledging Selcallcode.Note:The emergency cycling option is controlled at the time of programming. If emergency cyclingis disabled, then the emergency sequence is sent only once, and no transmit/receive cyclingoccurs.2. The radio then adopts a transmit/receive cycle, which allows the base or despatcher to monitoractivity in the vicinity of the radio.The radio can be removed from this mode either by receiving a reset code from the base or despatcher,during one of its receive periods, or by turning the radio off and back on, without operating the emer-gency switch.A trailing alarm tone can be sent with the emergency sequence, if the alarm tone was enabled when theradio was programmed.Other Selcall FeaturesYour T2020IImay be programmed with other Selcall functions. Consult your Tait dealer for more infor-mation on the following functions:●Quiet Status Interrogation (QSI)●Automatic Numbering Identification (ANI)●Stun●Deferred Calling●Cancel call indicators on remote reset
