Introduction This subsection covers the setting up of the test equipment for servicing
the radios, as well as related aspects:
■setting up of test equipment, including test unit
■use of test unit
■installing programming and calibration applications
■basic programming and calibration tasks
■invoking CCTM (computer-controlled test mode)
■summary tables of CCTM commands and error codes
■visual and aural indications provided by radio
The last-named aspect applies to control heads with UI, and concerns
the
STATUS LEDs and LCD screen, and the various alerts and confidence
tones emitted from the speaker.
Connect Equipment Connect the test equipment to the radio as shown in Figure 1.1. Use the
test unit, cables and adaptor of the service kit. The face of the test unit is
fitted with a speaker, five switches, and the following connectors:
■ “RADIO” connector (DB15 plug)
■ “COMPUTER” connector (RJ12 socket)
■ “TXAUDIO” connector (BNC socket)
■ “RXAUDIO/SINAD” connector (BNC socket)
These connectors are all required for connecting the test equipment and
radio. Figure 1.2 illustrates the face of the test unit.
Use of Test Unit The test unit facilitates the testing of the receive and transmit functions
of radios. When the switches are set for the required mode, the test unit
automatically routes all signals to the appropriate destinations. The unit
may be used with both mobile and portable radios. A full description is
given in the accessories manual. As shown in Figure 1.2, the switches
are:
■ SELECTOR switch
■ HOOK switch
■ MODE switch
■ AUDIO IN switch
■ AUDIO OUT switch
For servicing TM9100 radios set the
SELECTOR switch to “TM9100” . For
testing receive and transmit functions respectively, the remaining switches
must be set as described below. (When programming or calibrating
radios the switches have no effect, although it is good practice to set the
MODE switch to “RX” .)

Settings for
Receive Tests For receive tests set the switches on the test unit as follows:
■ HOOK switch : “HOOK OFF”
■ MODE switch : “RX”
■ AUDIO IN switch : “OFF”
■ AUDIO OUT switch: “SPEAKER” or “LOAD”
In the last-named case, with the switch in the “SPEAKER” position, the
received audio is output from the test unit’s speaker. In the
“LOAD”
position a 16 Ωload is switched into the circuit in place of the test unit’s
speaker. Note, however, that the AUDIO OUT switch has no effect on the
radio’s speaker.
Settings for
Tr an sm i t Tes t s For transmit tests set the switches on the test unit as follows:
■ HOOK switch : “HOOK OFF”
■ MODE switch : “RX” initially
■ AUDIO IN switch : “MIC AUDIO”
■ AUDIO OUT switch: (immaterial)
When ready to transmit, set the
MODE switch to the “TX/PTT” position.
This switch functions in the same way as the PTT switch on the
microphone.

Computer-controlled
Te st M o de The servicing procedures require a radio to be placed in the computer-
controlled test mode. In this mode CCTM commands can be entered at
the test PC. These commands are then relayed via the test unit to the
radio. Certain CCTM commands cause the radio to carry out particular
functions; others read particular settings and parameter values in the
radio. The CCTM commands of use in servicing radios are listed in
Table 1.1 to Table 1.5, grouped according to category.
Terminal Program
for CCTM To place a radio in CCTM requires the use of a terminal program on the
test PC. An example is HyperTerminal, which is supplied with
Microsoft Windows. As a preliminary, first select the settings for the
communications port as follows:
1. Open the terminal program. (In the case of HyperTerminal, click
“Start” > “Programs” > “Accessories” > “Communications” >
“HyperTerminal” .)
2. In the terminal program first select the COM port to which the
radio is connected. Then select the following settings for the port:
■bits per second : 19 200
■data bits : 8
■parity : none
■stop bits : 1
■flow control : none
3. Click the
“OK” button (or equivalent).
4. Save the file with the port settings under a suitable name. For
subsequent sessions requiring the terminal program, open this file.

Invoking CCTM Using the terminal program, place the radio in CCTM as follows:
1. Enter the character
^ to reset the radio.
2. As soon as the radio is reset, the letter
v is displayed. (If an
uppercase letter V appears, this implies a fault.)
3. Immediately the letter
v is displayed, enter the character % . (The
character % must be entered within half a second of the letter v
appearing.)
4. If the character
% is accepted, the character – is displayed in
response, and the message CL (two-digit display) or C (one-digit
display) appears on the radio’s LCD screen. This implies that the
radio has entered CCTM. If the attempt fails, repeat Steps 1 to 3.
CCTM Error Codes Once the radio is in CCTM, the CCTM commands may be entered as
shown in Table 1.1 to Table 1.5. Depending on the command, a
response might or might not be displayed. If an error occurs, an error
code will be displayed. Possible error codes are listed in Table 1.6.

Visual and Aural
Indications In radios that have a control head with UI, visual and aural indicators give
information about the state of the radio. Visual indications are provided
by the
STATUS LEDs, function-key LEDs, and LCD screen on the front
panel. The information conveyed by the STATUS LEDs is listed in
Table 1.7. The behaviour of the function-key LEDs depends on the way
the function keys are programmed; further information is not
appropriate in this manual. The LCD screen normally displays only the
number of the channel to which the radio is tuned. Other displays will
be mentioned where necessary but are not summarised here. Aural
indications are provided in the form of different tones emitted from the
speaker. The information conveyed by the tones is given in Table 1.8.
Not all of the tones listed are relevant to the servicing of radios but they
are included for the sake of completeness.
Table 1.6 CCTM error codes
Error code Description
C01 An invalid CCTM command has been received. Enter a valid CCTM command.
C02 A valid CCTM command with invalid parameters has been received. Re-enter the CCTM
command with valid parameters.
C03 A valid CCTM command has been received but cannot be processed at this time. Enter the
CCTM command again. If the error persists, power the radio down and up again, and re-enter
the CCTM command.
C04 An error occurred on entry into CCTM. Power the radio down and up again, and place the

2 Calibration basics
Tait TM9000 radios are designed to be totally electronically tuned. No
physical tuning is required, as all tuning is done by electronic trimming
usually in the form of a digital-to-analog converter (DAC). The calibration
process uses a PC running the calibration software, which is connected to a
radio via an RS232 programming cable. RF in/out and audio in/out from
the radio are also provided for connection to test equipment.
2.1 Calibrating the radio
To calibrate the radio
1. Connect a radio to your PC and test equipment. For more
information, refer to the section on calibration equipment setup in
the TM9100 Service Manual.
2. Read the radio.
3. Select the File > Save menu command to save the radio’s current
calibration database to disk. This will enable you to view data (see
“Viewing calibration files” on page 21) and re-program with a
previous calibration database if necessary.
4. Either:
■Change deviation or squelch settings (see “Deviation and squelch
thresholds” on page 27), or
■Complete some calibration tests (see “Calibration tests” on page
22).
5. View and check the calibration data calculated (optional - see
“Viewing calibration test results” on page 21).
6. Program the radio.
Note Before performing some tests, the radio must contain at least
approximate receiver calibration settings. If the radio being
calibrated has had settings deleted or default data programmed,
then program another radio’s calibration database into the radio
before starting the tests.

2.2 Using the calibration application
The following controls are unique to the Calibration Application.
■Sliders
■Option buttons
■Instruction boxes
■Radio Model toolbar.
Sliders
Sliders typically modify a DAC setting in the radio. A slider appears as a line
with a movable button, and two arrow buttons either side. Moving the
button will alter a value in a box to the right of the slider.
To adjust a slider
■Keyboard: select a slider using the Tab key. Press the left and right arrow
keys to adjust the value in the box in steps of 1, or the Page Up and Page
Down keys to adjust the value in steps of 10. To move the slider above
the upper safe limit of a field, hold shift and the right arrow key. The box
will turn red.
■Mouse: select a slider by clicking on it. Click the < and > buttons to
adjust the value in the box in steps of 1, click on the line either side of
the movable button to adjust the value in steps of 10, or click and drag
the movable button. To move the slider above the upper safe limit of a
field, hold shift and click the > button. The box will turn red.
Important The purpose of the upper safe limit is to protect the radio
from component damage. Only move sliders over this limit
if you are certain that it is necessary for the radio being cal-
ibrated.
Option buttons
Option buttons are round buttons used to select one of a group of mutually
exclusive options. They are typically used to select a current state.
To change data in a group of option buttons:
■Keyboard: select an option button using the Tab key. Select the radio

button by pressing the Space bar.
■Mouse: select an option button by clicking on it.
Instruction boxes
An instruction box contains text that describes the steps for a calibration
task. After completing each step, select or click the Next> button to move
to the next step.
Radio Model toolbar
When you read a radio, the type of radio will be displayed on the radio
model toolbar. There are currently three types of radio available for
calibration, Standard, Trigger Base, and Mid Power.
The following are the main differences between the radio models:
■Trigger Base radios use power levels approximately 6dB higher for each
of the three AGC (automatic gain control) test points, during the
Receiver test.
■The target power levels for mid-power radios are higher than for other
models during the Tx Power Control test.
■Mid-power radios use a lower current limit for each of the bias and
power tests.
2.3 Specifications form
You can use the Specifications form to view the Radio Model and Band. To
view the radio’s version and product code, select the Radio > Interrogate
menu command.
Before beginning the calibration tests:
1. From the forms tree, select Specifications.
2. Select the Radio > Read menu command.
Radio Model Displays the type of radio. This is a read-only field, and is set automatically
after reading the radio or opening a file, or manually using the Radio Model
toolbar.
Band Displays the frequency band in which the radio operates, as indicated by the
sixth and seventh characters in the product code. For example, TMAB1-
H600.
