Standard Operations
Switching the Radio On and Off
Switching the Radio On
Switch 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 switched
off.
Press and hold the Monitor (
) key until the indicator flashes. The radio then emits two short
tones. 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 Off
Switch the radio off by rotating the volume knob anticlockwise, to its primary position.
The T2020II retains some settings that are used when it is switched on again.

Selecting a Group
A group is simply a collection of channels grouped together for scanning or voting. Select a group the
same way as a channel.
Receiving a Call
The T2020II remains muted until another user makes a call. Listen for your call-sign when you hear
activity, 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 radio
may only unmute the speaker for some of this activity, depending on which signalling options are fitted
to your radio. Consult your Tait dealer about the signalling options available.

Using the Monitor Key
The Monitor (
) key enables you to monitor a channel for other users, regardless of the muting
controls programmed into your radio. There are three types of muting control which may screen your
calls:
RF squelch
Permits reception only if the radio's signals exceed a preset threshold. This
ensures that only intelligible signals are audible.
CTCSS or DCS mute
Permits reception only if a signal carries an inaudible tone or code specific to
your fleet or group.
Selcall mute
Permits reception only if the signal carries a special audible tone sequence
at the beginning of the transmission.
Note: The RF Squelch is always programmed to operate in your radio, but the CTCSS, DCS or
Selcall mutes are optional, depending on the way your radio is programmed.
11
The Monitor key may be programmed to override one or more of the mutes. Occasionally, you may find
the message you are receiving is still intelligible, but is being cut off periodically by the RF squelch. In
this 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 signalling mute. (If hookswitch monitoring is programmed, lifting the microphone off-hook has the same
effect.)
● To also override the RF squelch, hold the Monitor key for more than one second, until the radio
sounds two short tones, beep beep, and the MONITOR indicator flashes. Press again to restore.
Your T2020II may be fitted with the ability to hush (mute) another device, such as a car stereo, so that your
speech is clearly audible to other users when you transmit a call. Consult your Tait dealer to see if this
facility is active on your radio.
Making a Call
Select the desired channel, as previously described, for the party you wish to contact. If the BUSY
indicator is on, the channel is busy and you must wait until it is free, before proceeding. If you attempt to
transmit anyway, the WAIT indicator appears in the display, and your attempt is deferred. The radio
sounds 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 may

also have to press the Monitor (
● 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, identifying yourself by your call sign, and the person you wish to contact (for example - ‘Mobile-9 to
Base’). Release the PTT key when you have finished talking (see Figure 2).

Figure 2
Transmit Timer
Your T2020II is 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 terminated.
Economy Mode
The T2020II incorporates an Economy mode which conserves battery power by turning off some
internal circuitry, and dimming the control head back-lighting. This occurs after a predetermined period
of 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 immediately.
Scanning Channels
Your T2020II can be programmed with the scanning facility, which enables it to sequentially monitor a
number of channels, pausing its search when it detects activity on a channel. To change the channels
included in your scan group, refer to ‘User Programmable Scan’.
To Activate Scanning
Set 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 whenever 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 a
Channel’). The SCAN indicator appears in the display window, and scanning commences.

The T2020II now repeatedly scans through all programmed channels, searching for activity. When
activity is detected on a channel, the scan is halted, and the display window shows the active channel’s
name. (If signalling options are active in the radio, only activity with valid signalling tones halts the
scanning.) The radio pauses and unmutes on that channel, as long as the traffic remains, and the
SCAN 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 normal
manner and, when finished, place the microphone back on its hook to restart the scan.
To Stop Scanning
Scan mode is cancelled by selecting any non-scanning channel. The SCAN indicator then disappears
from the display window.
Making a Call
If you wish to make a call when the radio is in Scan mode, you may lift the microphone off-hook at any
time to suspend scanning. If the radio has halted scanning to monitor the traffic on a channel, it remains
on that channel when you lift the microphone off-hook. If the radio has found no traffic (i.e. has not
halted), 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 particular
channels. To use Selcall, your T2020II must be fitted with a Selcall module, and each channel preprogrammed to provide its own Selcall identity.
Making a Selcall Call
Call another party using Selcall, as follows:
1. Check that the radio is on the correct channel and that the channel is clear before attempting to
make 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 (usually

user’s radio, indicating that your call has been received. If you do not hear a tone, either the other
user's radio is incapable of generating the acknowledging tone, or it is off, or they are out of range
of your call.
Your T2020II may be programmed to display the status of the called unit, as follows:

If any control head activity is detected before any of the above messages are displayed, the acknowledge sequence is no longer expected, and messages will therefore no longer be displayed.
Group Calls
If you wish to call a group of other users, you may do so by dialling the digits common to all members of
the group and then using the # character as a substitute for all the remaining digits. If you are not sure
whether this facility has been programmed into your radio, consult your Tait dealer.
16
Example: You wish to call a group of users on the current channel (REGION2) with numbers which all
begin with 37, and have three more digits. After you have selected channel REGION 2, the sequence of
keystrokes, 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 a
few 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 cannot
all reply at once.
Receiving a Selcall Call
When you receive a Selcall call, the CALL indicator flashes and a ringing tone (similar to that of a
telephone) sounds from the speaker.

Note: Your T2020II may be programmed to display the caller’s identity when you receive a call. Consult your Tait
dealer for more information on this feature.
● To answer the call, lift the microphone off-hook and identify
yourself. As soon as you operate the PTT key, the ringing
tone stops.
● If you do not answer the call within a short time, the ringing tone
stops. The radio may then switch on another alerting device
(e.g. the horn in your car) to attract your attention.
17
● Your T2020II may be programmed to queue incoming calls. If this feature is enabled, the caller’s
identity is put in the queue after the ringing stops. All other call indicators are cleared when the
received 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 call
was 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 the
control head keys. (The function associated with the key you press will not be invoked.) Note that
if 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 the
ringing tone, burr burr. The caller then broadcasts a message to all members of your group.
18
Advanced User Operations
Most of the special features detailed below must be enabled during programming of the T2020II. Consult your Tait dealer to find out which of these features have been enabled in your radio.
Alphanumeric Entry Mode
The T2020II contains a number of memory locations which are able to be accessed with an alphanumeric entry or label, from the keypad. The alphanumeric label may be the same as a channel name or
it may be a quite separate word, person’s name or acronym which helps you find the appropriate
memory location. Each location contains information which selects a channel scan group, makes a
Selcall 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.
) keys to scroll through the
2. Locate the desired label by using the Up and Down (
list 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 the
radio to recognise the label. When it does, it displays the label in full. Pressing the Enter key
causes any instructions (channel selection, send call, and so on) contained in the memory
location to be carried out.
3. Press the Channel ( Ch ) key and the display changes from the label to the channel name. (The
radio 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 Selcall
code 24624. The sequence of keystrokes, and the corresponding display characters that appear, is as

Repeater Talkaround
Repeater Talkaround is a programmable option that allows your T2020II to bypass the repeater, and
transmit and receive calls directly on the repeater transmit frequency. This feature can be used, for
example, when you are out of range of the repeater.
1. Press the Channel (

Sending DTMF Tones (DTMF Option Fitted)
The keypad on the T2020II may also send Dual Tone Multiple Frequency (DTMF) tones (consult your
Tait dealer to see if this option is fitted to your radio). This gives you the ability to dial telephone numbers, 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. This
leaves the radio in DTMF mode, with the last number dialled showing in the display window.

2. Press the Enter (
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 you
dial. (Your radio may be programmed so that you need only press the number key.) The TX
indicator appears in the display as you dial.
- To set up a complete sequence of digits, push each number key in turn without pressing the PTT
key (although your radio may be programmed to transmit the tones live, anyway). Each number
appears in the display.
- When the sequence is complete, press the Enter key to transmit the digits. Even if the digits have
been 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 and
more efficient than sending the tones live.
4. Pressing any of the keys on the keypad causes the corresponding DTMF tone to sound, but this
does not indicate whether or not the tone has actually been transmitted. Watch your radio’s display 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 shift
key, to alter the function of some of the keypad keys, as follows:
ABC
gives DTMF tone A
PTT +
JKL
gives DTMF tone B
PTT +
TUV
gives DTMF tone C
PTT + 0
PTT +
gives DTMF tone D

5. Press the Up and Down keys to scroll through all the available channels. The SCAN indicator
indicates those channels that are included in the user programmable scan group, and a flashing
SCAN indicator indicates the home channel.
6. To add or delete a channel from the scan group, select the required channel and then press the
Enter 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 1
second. The SCAN indicator then flashes.
Note: You can only delete a normal channel from the scan group. If the home channel is to be deleted
from the scan group, you first have to define another channel as home channel and then delete
the 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 returns
the radio to the normal operating mode if no operator activity has been detected for 10 seconds.

Call Queuing (Selcall Option Fitted)
Your T2020II can be preprogrammed to queue incoming calls. This feature enables the storage of up
to 10 caller identities.
Call Queue Not Empty
Whenever there is an entry in the call queue, the Function menu is automatically active, with ‘CALL
QUE’ appearing in the display window as the current item. This means that the radio always reverts to
the 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 Queue
The Call queue can be accessed through the Function menu. This is the same mode that is used to alter
user options.
1. Press the Function (
window.
Fn
) key. The item last viewed while in this mode appears in the display
2. Scroll through the displayed items using the Up and Down (

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 total
number of entries in the list. An example of the display would be ‘CL 01/02’, indicating that the
current entry is entry number one, with a total of two entries in the queue. Use the Up and Down
) key to delete an entry from the
keys to scroll through the list of entries, and the Zero ( 0
queue.
23
3. Press the Enter key, and the caller identity of the entry in the display window appears. Again, you
can use the Up and Down keys to scroll through the list of entries, and the Zero key to delete the
entry from the queue.
4. Press the Enter key again when the caller identity of the entry is being displayed, and call-back is
initiated. The entry is then automatically removed from the queue. Note that the call-back sequence is based on the caller identity.
Exiting the Call Queue
Exit 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 last
entry in the call queue is deleted. This can be done either by using the Zero key, or making a call-back.
Queuing Calls
The 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 radio
resumes 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 Full
Whenever the queue is full, the radio continues to receive calls, but does not resume what it was doing
prior 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.
24
Changing 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 be
sent with each call you make, indicating your current status. Each code’s description and number (0 to
99) is set when the radio is programmed. Typical descriptions might be ‘AT LUNCH’, ‘EN ROUTE’, and
so on.
1. Press the Status ( STAT ) key to enter Status mode. How status codes are displayed by your
radio depends on which status display function is active (see the later section, ‘Altering User
Options’).
2. If ‘normal display’ (STAT NRM) is active, the complete eight character word for the currently
selected status is displayed.
Scroll through the choices using the Up and Down (
) keys, until you find one
appropriate for your present activity. Alternatively, type the number for your new status directly
using the keypad. The new status description appears in the display (you may need to press the
) key first).
Enter (
3. If ‘fixed display’ (STAT FIX) is active, your own status is displayed as a code at the right of the
display (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 for
your new status directly using the keypad. The new status code appears in the display (you may
need 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 Selcall
sequence causes the radio to transmit another user defined Selcall or DTMF sequence on the programmed call diversion channel. The sequence (number) to be transmitted and the call type (Selcall or
DTMF) can be entered by the user while in Call Diversion Setup mode.
Activating Call Diversion Setup Mode
Call Diversion Setup mode can be accessed through the Function menu.
1. Press the Function (
window.
Fn
) key. The item last viewed while in this mode appears in the display
2. Scroll through the displayed items using the Up and Down (

3. On entry into the setup process, the display flashes the last selected diversion call type, either
Selcall or DTMF. Use the Up and Down keys to toggle between the two options. Note that if the
DTMF 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 information on this).
6. Press the Enter key to confirm the diversion sequence and to put the radio into Call Diversion
mode.
Exiting Call Diversion Mode
At any stage of the call diversion setup process, any mode key-press initialises that mode, and therefore takes the radio out of the Call Diversion Setup process or Call Diversion mode. This includes the
Function ( Fn ) key.
Receiving a Call During Call Diversion
When a standard incoming call is received by the radio in Call Diversion mode, the programmed autoacknowledge sequence is transmitted, as for a normal call. However the programmed diversion status
is transmitted instead of the normal acknowledge status, to inform the caller that the call has been
diverted.
The radio then switches to the programmed call diversion channel and transmits the sequence that has
been 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 prior
to the call diversion.
26
Making a Call to a Radio In Diversion Mode
Your T2020II can be programmed to respond to a diversion status report when making a call. When it
detects the diversion status in the acknowledge from the radio it has called, it displays ‘DIVERT’, to
indicate that the call has been diverted. It then proceeds to switch to the programmed diversion channel.
Emergency Operation (Selcall Option Fitted)
Your T2020II can be set to make emergency calls to a preprogrammed party (usually your base or
your despatcher). To use this capability, the radio must be fitted with the Selcall option, and be connected to a hidden emergency switch. Alternatively, the Auxiliary (
) key on the control head may
be preprogrammed to send an emergency call.
1. To send an emergency call, operate the hidden switch, or press the Auxiliary (
) key. There
is no change in the T2020II control head indicators, but the radio sends a Selcall emergency
code to the preprogrammed party every few seconds, until it receives an acknowledging Selcall
code.
Note: The emergency cycling option is controlled at the time of programming. If emergency cycling
is disabled, then the emergency sequence is sent only once, and no transmit/receive cycling
occurs.
2. The radio then adopts a transmit/receive cycle, which allows the base or despatcher to monitor
activity 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 emergency switch.
A trailing alarm tone can be sent with the emergency sequence, if the alarm tone was enabled when the
radio was programmed.
Other Selcall Features
Your T2020II may be programmed with other Selcall functions. Consult your Tait dealer for more information on the following functions:
● Quiet Status Interrogation (QSI)
● Automatic Numbering Identification (ANI)
● Stun
● Deferred Calling
● Cancel call indicators on remote reset

Altering User Options
While most of the features available on the T2020II are able to be customised with the Tait programming software, some may be directly accessible to you, to alter according to your own requirements.
This is done via the Function menu, as follows:
1. Press the Function (
display window.

Appendix
Maintenance of your T2020II
The T2020II requires no regular maintenance, other than ensuring that all cables and connections are
secure, and that no damage has occurred to the antenna or wiring.
Troubleshooting
If the front panel indicators do not light up when you turn the radio on, it is likely that no power is
reaching the T2020II. Check the following:
! Is the power connector firmly plugged into the rear of the T2020II ?
! Are the in-line fuses in good condition?
! Is the power cable securely connected to the vehicle battery or power supply?
If all appears to be in order, then contact your Tait dealer for further assistance.
Despatcher Operation
The T2020II can also be used for despatcher operation, mounted on top of its companion T2008 power
supply, which is available separately. Consult your Tait dealer for more information.
