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...

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...

switch 3 is in the open condition.
6. Press the orange button again; “3/1” appears, which indicates that 
switch 3 is in the closed condition.
7. Rotate the mode selector knob; ”4/0” thru ”4/15” appears, which 
indicates that knob 4 is in mode position 1 thru 15.
8. Rotate the concentric switch; ”65/0” and “65/1” appears.

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...

Operational Display 
CodesDuring 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 12 to aid in understanding 
particular operational error code displays.

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...
