The following table lists the tools recommended for
working on this family of radios; these tools are also
available from Motorola. Note that the R-1319A
solder/desolder workstation requires the use of some
reflow nozzles. The nozzles’ part numbers and general
descriptions are listed in the table with the R-1319A.Also note that the R-1070A workstation requires the use
of a specific “heat focus head” for each of the compo-
nents on which this item is used.  Each of these heat
focus heads must be ordered separately.  The indi-
vidual heat focus heads (and the components on which
they are used) are listed at the end of the table.MOTOROLA PART NO. DESCRIPTION  APPLICATION

							A. General
The HT 1000, MT 2000, MTS 2000, and MTX series
radios have been prepared to meet published specifica-
tions through their manufacturing process, with the use
of laboratory-quality test equipment of highest accuracy.
The recommended field service equipment approaches
the accuracy of the manufacturing equipment with a few
exceptions. Accuracy of the equipment must be main-
tained in compliance with the manufacturers
recommended calibration schedule.
B. Setup
Supply voltage can be connected from the battery
eliminator. The equipment required for alignment proce-
dures is connected as shown in the Radio Alignment
Test Setup diagram.
Initial equipment control settings should be as indi-
cated in the following table, and should hold for all
alignment procedures except as noted in Table 40-4.
Table 40-4. Initial Equipment Control Settings
C. Test Mode
1. RF Test Mode, HT 1000 Radios
When the HT 1000 radio is operating in its normal
environment, the radios microcontroller controls the
RF channel selection, transmitter key-up, and
receiver muting. However, when the unit is on the
bench for testing, alignment, or repair, it is removed
from its normal environment. It cannot receive com-
mands from its system and, therefore, the internal
microcontroller will not key the transmitter nor
unmute the receiver. This prevents the use of nor-
mal tune-up procedures. To solve this problem a
special routine, called TEST MODE or “air test,” has
been incorporated in the radio.
To enter test mode:
(a) Turn the radio on.
(b) Within ten seconds after the self test is com-
plete, press the monitor button (side button 3,
SB3) five times in succession. After the fifth
press, a tone is emitted to indicate that the rf
test mode has been entered. (c) Each additional press of SB3 will advance to
the next test channel. (refer to Table 40-6), and
a corresponding set of tones will indicate the
channel.
(d) Pressing SB2 will scroll through and access test
environments as shown in Table 40-5.
NOTE
Transmit into a load when keying a radio under
test.
To exit test mode, turn the radio off then back on.
Table 40-5. Test Environments,  HT 1000 Radios
2. Control Head Test Mode, HT 1000 Radios
To check the buttons and the switches, perform the
following tests:
(a) Turn radio on
(b) After the self test is complete, press the monitor
button (side button 3, SB3) five times in succes-
sion, within 10 seconds. After the fifth press, a
tone is emitted to indicate that the RF test mode
has been entered.
(c) Exit the RF test mode and enter the control
head test mode by pressing and holding SB3
for more than three seconds. Upon entering the
control head test mode, a tone is emitted and
the green LED begins flashing. The green LED
continues to flash until the control head test
mode is exited.  
NOTE
Return to the RF test mode by pressing and hold-
ing SB3 for more than three seconds. Then
re-enter the control head test mode by pressing
and holding SB3 for more than three seconds.
(d) Test each switch (toggle, rotary, or button-actu-
ated) by changing the position of the switch. A
tone is emitted to indicate a “good test“ each
time a switch position is changed.
NOTES
1. Pressing and releasing a button-actuated
switch are both considered switch-position
changes.
2.  No tone when a switch position is changed
indicates a test failure.

(e) Test the on/off volume potentiometer/switch by
rotating the potentiometer clockwise and counter
clockwise. The loudness of tone beeps will
increase and decrease accordingly.
NOTE
During test mode, the volume level is not regulated
to the same limits as during normal radio operation. 
To exit test mode, turn the radio off then back on.
3. RF Test Mode, MT 2000, MTS 2000, and MTX 
Series Radios 
When the MT 2000, MTS 2000, or MTX series radio
is operating in its normal environment, the radios
microcomputer controls the RF channel selection,
transmitter key-up, and receiver muting. However,
when the unit is on the bench for testing, alignment,
or repair, it is removed from its normal environment.
It cannot receive commands from its system and,
therefore, the internal microcomputer will not key the
transmitter nor unmute the receiver. This prevents
the use of normal tune-up procedures. To solve this
problem a special routine, called TEST MODE or “air
test,” has been incorporated in the radio.
To enter test mode:
(a) Turn the radio on.
(b) After the self test is complete, press the monitor
button (side button 3, SB3) five times in succes-
sion, within 10 seconds.
(c) After “RF TEST” appears (on 14-character dis-
plays) or “RF TST” appears (on 6-character
displays), press the orange button on top of the
radio once. “1 CSQ” appears, indicating: test fre-
quency 1, carrier squelch mode.
(d) Each additional press of SB3 will advance to the
next test channel. (Refer to Table 40-8.)
(e) Pressing SB2 will scroll through and access test
environments as shown in Table 40-7.NOTES
1.  Transmit into a load when keying a radio
under test.
2.  Radios without display indicate test-environ-
ment function by emitting a corresponding
number of beeps. See Table 40-7. 
4. Control Head Test Mode, MT 2000, MTS 2000,
and MTX Series Radios
To check the display, the buttons, and the switches,
perform the following tests:
(a) Turn radio on
(b) After the self test is complete, press the monitor
button (side button 3, SB3) five times in succes-
sion, within 10 seconds.
(c) After ”RF TEST” appears on the display, press
side button 1 (SB1), “CH TEST” (14-character
radio) or “CH TST” (6-character radio) appears
on the display.
(d) Next, press and hold the orange button on top of
the radio; all segments on the display will light,
and the LED on the control top will illuminate a
yellowish color.
(e) Release the orange button; ”3/0” appears, which
indicates that switch 3 is in the open condition.
(f) Press the orange button again; “3/1” appears,
which indicates that switch 3 is in the closed
condition.
(g) Rotate the mode selector knob; ”4/0” thru ”4/15”
appears, which indicates that knob 4 is in mode
position 1 thru 15.
(h) Rotate the concentric switch; ”65/0” and “65/1”
appears.
(i) Rotate the volume control; “2/0” thru “2/255”
appears.

A. Power-up Display Codes
At power-up, the radio performs cursory tests to
determine if its basic electronics and software are in
working order. Problems detected during these tests are
presented as error codes on the radio display. The pres-
ence of an error code should prompt the user that a
problem exists and that a service technician should be
contacted.
Self-test errors are classified as either fatal or non-
fatal. Fatal errors will inhibit user operation, while
non-fatal errors will not. Use Table 40-11 to aid in under-
standing particular power-up error code displays.B. Operational Display Codes
During operation, the radio performs dynamic tests
to determine if it is working properly. Problems detected
during these tests are presented as error codes on the
radio display. The presence of an error code should
prompt a user that a problem exists and that a service
technician should be contacted. Use Table 40-12 to 
aid in understanding particular operational error code
displays.

NOTE
Due to the nature of fatal ROM & RAM errors, it may not be possible to present an error code on the display.  In these
cases the radio will attempt to display the appropriate error code, generate an illegal mode tone for one second and then
reset its microcontroller.

SECTION V. RADIO ALIGNMENT PROCEDURE
A. General
An IBM PC (personal computer) and RSS (Radio
Service Software) are required to align the radio.  Refer
to the applicable RSS manual for installation and setupprocedures for the software.  To perform the alignment
procedures, the radio must be connected to the PC, RIB
(radio interface box), and Universal Test Set as shown
in Figure 40-1.
