							Appendix A- 3
Troubleshooting Secure 
OperationsRefer to Section 6 of this radio service manual for disassembly and 
reassembly information, refer to Section 9 “Removal And Installation” 
for secure module and pad orientation, and refer to the radio theory/
troubleshooting manual for a general overview of troubleshooting 
information and procedures. A key variable loader and oscilloscope are 
needed to troubleshoot the Secure Module.
NOTE:The Secure Module itself is NOT serviceable. If 
the Secure Module is found to be defective 
then it must be replaced.
ERROR 09/10The MTS 2000 Series Handie-Talkie™ Portable Radio automatically 
performs a self test on every power-up. Should the radio fail the self 
tests, the display will show “ERROR XX/XX” (where XX/XX is 
alphanumeric) accompanied by a short beep. If the display shows 
“ERROR 09/10” or “E09/10”, then the radio failed the secure power-up 
self tests and the host microcontroller is unable to communicate with 
the Secure Module via the SPI bus. Turn off the radio, check the battery 
connection, and turn the radio back on. If the radio still does not pass 
the self tests, then a problem exists with the secure operations of the 
radio.
Since the module is removable, a good first step in troubleshooting 
secure operation is simply to replace the suspect Secure Module with a 
known working module. If this does not fix the problem, then the 
original module is probably not the cause of the problem. If the new 
module does fix the problem, then the original module must be 
replaced. 
A complete procedure for troubleshooting this error is listed below:
1. Turn the radio off, check the battery connection, and turn the 
radio back on.
2. If the error condition still exists, check that a Secure Module is 
installed and make sure that it is properly connected to the 
controller board. To do this, refer to the disassembly and 
reassembly sections of this manual.
3. Turn the radio back on.
4. If the error condition still exists and a working secure module with 
the same kit number is available, replace the suspect module with 
the working module.
5. If the problem persists, disassemble the radio and check the 
encryption connector SPI pins (listed in Appendix Table 1) for data 
transitions when the radio is turned on and off. If activity is not 
seen on all five lines, check both sides of the connector for broken 
connections.
6. Troubleshoot the Controller Board.
Keyloading ProblemsUse the following procedure to troubleshoot keyloading problems:
1. Verify that the correct Key Variable Loader (KVL) is being used for 
the particular encryption algorithm present in the radio. Refer to 
Appendix Table 2: 
						

							Appendix A- 42. 2.Connect the KVL to the radio via the TDN9390A keyloader 
cable. When the cable is connected to the radio, the radio should 
enter the keyloading mode of operation, and the radio should 
display “KEYLOADING” or “KEYLDG” and make a beep tone.
3. 3.If the radio displays “ERROR 09/10” or “E09/10” then go to the 
ERROR 09/10 troubleshooting section. 
4. 4.If the radio does not go into keyloading mode, detach and 
reattach the keyloader cable. 
5. 5.If there is still a problem, refer to the universal connector 
illustration found in the schematic and circuit board section of 
this manual, and short pins 8, 10, and 12 on the universal 
connector together. If this causes the radio to go into keyloading 
mode, then replace the keyloader cable.
6. 6.If the radio still does not go into keyloading mode, check the 
continuity of the Front Cover/Display Flex and make sure that the 
Flex is properly connected to the Universal Connector and to the 
Controller Board.
7. 7.If the radio does go into keyloading mode, but after starting the 
keyloading process the KVL display indicates “X FAIL”, then check 
to see if there are transitions on pins 13, 15, and 16 of connector 
P1 on the Secure Module during a keyload. 
8. 8.If there are no transitions on any one of these lines during a 
keyload, check the integrity and continuity of the Expansion 
Board Connector. If it is OK, try replacing the Controller Board.
9. 9.If there are transitions on these lines, try replacing the Secure 
Module.
10.10.If the KVL display indicates “X PASS” but you cannot hear a 
keyload verification tone, then check the volume of the radio. If 
the volume is OK, troubleshoot the receive routing paths in the 
radio.
Service AidA cable, Motorola kit number TDN9390A, connects the MTS 2000 
radio universal connector to the keyloader.

							Appendix A- 5 enable the secure options by updating the codeplug, and how to tune 
the radio for optimum secure performance.
Physical Retrofit of 
Secure ModuleThe radio must be partially disassembled to install the secure module.
Follow the disassembly procedures in Section 6, located toward the 
front of this manual. Proceed through “Disassembly to Board Level”) 
step 8, where the front cover has been removed and the controls flex 
has been disconnected from the controller board. 
Continue through step 9a, to loosen the front shield. Do not 
completely remove the front shield. Simply raise the lower portion of 
the shield while the opposite end is still connected to the top of the 
radio. With the front shield raised, observe the controller board which 
takes up the bottom third of the radio. On the lower right corner of the 
controller board is an empty female connector, which will be used to 
mate the controller board to the secure module. Place the secure 
module (component side toward controller board) over the controller 
board with the secure module’s male connector placed above and 
aligned to the female connector on the controller board. Interlock the 
connectors by pressing down on the back of the secure module. The 
secure module has now been installed. Reassemble the radio according 
to the reassembly instructions in Section 6, located toward the front of 
this manual. Begin with “Reassembly (Control Top/Front Shield/
Controls Flex as a unit to Chassis), step 2.
Update Codeplug Through 
RSS
GeneralOnce the secure module is installed, the radios codeplug must be 
reprogrammed so that the new hardware can be used. There will also 
be some secure options that the user may or may not want to activate. 
Appendix Table 3, at the end of this appendix, gives a quick reference 
to several properties and a brief description for each parameter. Refer 
to the RSS manual for general instructions in the use of RSS.
Set Secure-Equipped FieldThe radio must be reprogrammed to utilize the secure module. At the 
RSS main menu, press F4 for the CHANGE/CREATE/VIEW menu. Press 
F3 for the Radio Wide Buttons, Switches, Display, Scan, Phone screen. 
Press F2 for Radio Wide Options screen. Here, press tab to reach the 
Secure Equipped field. Press up/down arrow keys to select YES.
Set XL IC Present FieldIf the secure module has an XL IC (the Range Extension or -XL option), 
the radio must be reprogrammed to show that this IC is present. While 
still in the Radio Wide Options screen, press F6 to see Secure Options. 
Press Tab until the XL IC Present field is highlighted. Press up/down 
arrow keys to select YES. If the secure module does not have an XL IC, 
set the XL IC Present field to NO.

C a u t i o n
Anti-static precautions must be observed at all 
times. 
						

							Appendix A- 6 Enable Secure On Desired 
ChannelsTo actually use the secure option, Secure must be enabled on the 
channels for which it is desired. A channel can be strapped to secure-
only, or clear-only, or secure/clear-selectable.
For conventional channels, proceed as follows: Press F4 at the Main 
Menu to see the CHANGE/CREATE/VIEW menu. Press F6 to see 
Conventional Systems, Personalities, MDC, Options. Press F3 to see 
Conventional Personalities, Options. Press F6 to see the SECURE 
OPTIONS screen. Press Tab to select the Secure/Clear Strapping field.
For trunking channels, proceed as follows: Press F4 at the Main Menu 
to see the CHANGE/CREATE/VIEW menu. Press F4 to see Trunking 
Systems, Personalities, Call Lists, Options screen. Press F4 to see 
Trunking Personalities: Talk Groups, Emergency Options, etc. Press Tab 
to select the Strapping field. An Announcement Group must be 
specified for the Strapping parameter to appear. This selects the 
Announcement Group Strapping. Press F7 to select Talk Groups. Press 
Tab to select the strapping of each Talk Group.
Other Secure OptionsThere are other secure options that can be changed on a per-channel 
basis, such as: Proper Code Detection, Transmit XL, or CFB. For 
conventional channels, these options are found on the same screen as 
Secure/Clear Strapping (F4/F6/F3/F6). These options are XL Transmit, 
Scan Holdoff Strapping, RX Modulation, and Proper Code Detect. For 
trunking channels, the only selectable option is Proper Code Detect. 
This can be found by going to the MORE OPTIONS screen (F9) from 
the screen that was used to select secure/clear Strapping for trunking 
channels.
Secure Retrofit TuningAfter installing a secure-retrofit board into a radio, the secure TX 
deviation and the secure RX discriminator level must be tuned. Follow 
the procedure outlined in Section 9 “Secure Alignment Procedure” 
in this publication for the tuning of these two secure-related 
alignments.
The TX deviation balance (compensation) does not need to be 
performed as part of the secure retrofit procedure. Use the transmit 
deviation balance (compensation) procedure as outlined in this 
appendix, only when a complete radio alignment is being performed 
with a secure board installed.
Secure Alignment 
Procedure
GeneralFor optimum radio performance, the secure transmit deviation and 
the receive discriminator level must be set. Refer to Section 5, “Radio 
Alignment Procedure”, for a description of the radio alignment test 
setup, an RSS service menu overview, and for general radio tuning 
procedures. All normal radio tuning should be performed in the 
proper sequence before proceeding with secure tuning.
Note that the transmit deviation balance (compensation) tuning must 
be performed differently if a secure board is installed in the radio. 
Follow the procedure changes outlined below when tuning transmit 
deviation balance, and complete the normal tuning. Then proceed  
						

							Appendix A- 7 with the additional tuning for secure TX deviation and secure RX 
discriminator level tuning.
Transmit Deviation Balance 
(Compensation)When tuning with a secure board installed, the coupling capacitor 
inside the RKN4035A Test Cable will cause rolloff of the low port 
modulation. To fix this, the cable should be dc coupled (“VOL” 
position) and an external coupling capacitor (1.3µF or larger) must be 
placed in series with the signal source input to the AC/DC MTR.
Follow the “Transmit Deviation Balance (Compensation)” 
procedure outlined in Section 5, except change step 3 as follows:
3. Set the RTX4005B Test Box meter selector switch to the “VOL” 
position, and connect the signal source to the AC/DC MTR port 
thru a 1.3µF capacitor. Inject an 80 Hz tone at 100mVrms thru this 
capacitor. Keep the ac voltmeter in parallel to the AC/DC MTR 
input to ensure the proper input signal level.
Secure TX DeviationTransmit deviation balance (compensation) and transmit deviation 
limit adjustments should be completed before secure deviation is 
adjusted. Remember to use the new transmit deviation balance 
procedure outlined in the previous paragraphs before performing the 
following steps.
1. From the SERVICE menu, press F2 to select TRANSMITTER 
alignment.
2. Press F8 to select the SECURE TX DEV softpot.
3. Press F6 to key the radio on the test frequency. The screen will 
indicate that the radio is transmitting.
4. Measure the secure deviation on your service monitor.
5. Use the up/down arrow keys to adjust the secure deviation per 
Appendix Table 3.
6. Press F6 to dekey the radio. Press F8 to program the softpot value.
7. Press F10 to return to the TRANSMITTER menu.
Secure RX Discriminator 
Level8. Set the RTX4005B Test Box meter selector switch to the “MX 
DISC” position, and connect an ac volt-meter (capable of 1mV 
resolution on a 2V scale) to the test box AC/DC meter port.
9. From the SERVICE menu, press F3 to select RECEIVER alignment.
10.Press F8 to select the SECURE DISCRIMINATOR LEVEL softpot. 
The screen will indicate the receive test frequency to be used.
11.Set the RF test generator to the receive test frequency. Set the RF Appendix A Table 3.  Secure Deviation

							Appendix A- 8level at the radio standard antenna port to 1mV (-47dBm) 
modulated with 3.0 kHz FM deviation of a 1 kHz tone.
12.Use the UP/DOWN arrow keys to obtain a discriminator level 
between 206 - 218mVrms (target value of 212 mVrms) observed on 
the ac volt-meter.
13.Press F8 to program the softpot value.
14.Press F10 to return to the RECEIVER menu.
Removal And InstallationRefer to Appendix Figure 2, Secure Module Location Detail, when 
adding, removing, or replacing the secure module and/or secure 
module pad. Notice the orientation of the secure module and the 
secure module pad to the controller board.
RemovalPerform the disassembly procedure outlined in Section 6, up to and 
including removing the radio’s front shield. Remove the secure 
module by pulling it out and away from the controller board. 
NOTE:The secure module and the controller board 
connect via a plug and jack located at the 
opposite corner from the round popple switch.
Remove the secure module pad as necessary.
Replacement/InstallationPerform the disassembly procedure described in the preceding 
paragraphs. Refer to Appendix Figure 2 for secure module pad and 
secure module board orientation. If the secure module pad was 
removed, place the removed pad or a new pad (Motorola part number 
7505670Z01) on the controller board and ensure that it seats flush 
with the controller board on all sides. Place the secure module on the 
secure module pad. Press the secure module plug into the controller 
board jack with enough force so that the jack and plug snap together.
