Control Head Test Mode, 
HT 1000/JT 1000 RadiosTo check the buttons and the switches, perform the following tests:
1. Turn radio on.
2. After the self test is complete, press the monitor button (side 
button 3, SB3) five times in succession, within 10 seconds. After 
the fifth press, a tone is emitted to indicate that the RF test mode 
has been entered.
3. 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 
holding SB3 for more than three seconds. Then 
re-enter the control head test mode by pressing 
and holding SB3 for more than three seconds.
4. Test each switch (toggle, rotary, or button-actuated) by changing 
the position of the switch. A tone is emitted to indicate a “good 
test” each time a switch position is changed.
NOTE:Pressing and releasing a button-actuated 
switch are both considered switch-position 
changes.
NOTE:No tone when a switch position is changed 
indicates a test failure. Test the on/off volume 
potentiometer/switch by rotating the 
potentiometer clockwise and counter  Table 6 Test Frequencies, HT 1000 / JT 1000

							10clockwise. 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.
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 radio’s 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:
1. Turn the radio on.
2. After the self test is complete, press the monitor button (side 
button 3, SB3) five times in succession, within 10 seconds.
3. After “RF TEST” appears (on 14-character displays) or “RF TST” 
appears (on 6-character displays), press the orange button on top 
of the radio once. “1 CSQ” appears, indicating: test frequency 1, 
carrier squelch mode.
4. Each additional press of SB3 will advance to the next test channel. 
(Refer to Table 8.)
5. Pressing SB2 will scroll through and access test environments as 
shown in Table 7.
NOTE:Transmit into a load when keying a radio 
under test.
NOTE:Radios without display indicate test-
environment function by emitting a 
corresponding number of beeps. See Table 7. 
Control Head Test Mode, 
MT 2000, MTS 2000,

following tests:
1. Turn radio on.
2. After the self test is complete, press the monitor button (side 
button 3, SB3) five times in succession, within 10 seconds.
3. 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.
4. 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.

Error-Code
Displays
4
Power-up Display 
CodesAt 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 
presence 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 11 to 
aid in understanding particular power-up error code displays.

NOTE:Due to the nature of fatal ROM and RAM errors, it may not be possible to present

appropriate error code, generate an illegal mode tone for one second and then 
reset its microcontroller.

Radio Alignment 
Procedure
5
GeneralAn IBM PC (personal computer) and Radio Service Software (RSS) are 
required to align the radio. Refer to the applicable RSS manual for 
installation and setup procedures 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 1.

							18All service and tuning procedures are performed from the SERVICE 
menu, which is selected by pressing F2 from the MAIN MENU. 
Figure 2 illustrates how the RSS SERVICE screens are organized.
All SERVICE screens read and program the radio codeplug directly; you 
do NOT have to use the RSS GET/SAVE functions to use the SERVICE 
menus. You will be prompted at each screen to save changed values 
before exiting the screen. RSS references in this manual are to 
HT 1000 / JT 1000 RSS. Some slight differences may be noted it you are 
using the MTS/MTX RSS.
The radio contains internal test modes that can be accessed from the 
RSS. The test modes permit the service technician to easily select 
various frequency, modulation, and transmit power combinations to 
verify proper operation of the radio. The test modes can be used to 
check both transmit and receive operation. From the Service Menu 
press F6 to navigate to the TEST MODE screen. 
The SERVICE screens introduce the concept of the “softpot”, an analog 
SOFTware controlled POTentiometer used for adjusting all transceiver 
alignment controls.

C a u t i o n
Do NOT switch radios in the middle of any 
SERVICE procedure. Always use the EXIT key to 
return to the MAIN menu screen before 
disconnecting the radio. Improper exits from the 
SERVICE screens may leave the radio in an 
improperly configured state and result in 
seriously degraded radio or system performance.
