							Chapter 6 Basic Troubleshooting
6.1 Introduction
This chapter contains error codes and board replacement procedures. If the board does not pass all 
the performance checks in Chapter 3 or exhibits an error code listed below, then the circuit board 
should be replaced. If repair requires knowledge of details of component level troubleshooting, 
please send radio to a Motorola Service Center listed in Appendix A.
NOTE: To access the various connector pins, use the housing eliminator/test fixture along with the 
diagrams found in this section of the manual.  (See the section, Service Aids on page 2-2, 
for the appropriate Motorola service aids and tools parts numbers.)
6.2 Replacement Back Cover Kit Procedures
Once a problem has been isolated to a specific boar d, install the appropriate service kit (See Model 
Charts from page 1-5 to page 1-6), which is orderable.
• If a board is replaced, it does not necessarily  need to be retuned if it has been factory tuned. It 
should however be checked for performance befo re being placed into service. Of particular 
concern is the Bias DAC, which will need to be set  for the appropriate final device bias current 
prior to keying up the radio. If the bias is not pr operly set it may be possible to cause damage to 
the transmitter.
CAUTION: The Tuner Tool only allows the serial number of the blank board to be entered once.
Be very attentive during this procedure. 
						

							6-2Basic Troubleshooting: Power-Up Error Codes (Display Model only)
6.3 Power-Up Error Codes (Display Model only)
Upon powering up, the radio performs certain tests to determine if its basic electronics and software 
are in working order. Any error detected has an associated error code that is presented on the radio 
display. These error codes are intended to be used by a service technician when the radio 
generates the Self Test Fail Tone . If these tests are successfully completed, the radio will generate 
the Self Test Tone.
There are two classes of detectable errors, fatal and non-fatal. If it is considered as a fatal error, then 
the normal radio operation will be in hibited. Fatal errors include hardware errors detected by the 
microprocessor and certain memory errors. These  memory errors include incorrect ROM checksum, 
incorrect RAM checksum, and incorrect checksums  of codeplug (Persistent Storage) blocks that 
contain operating parameters. If the codeplug blo ck operating parameters are corrupted, operation 
of the unit on the proper frequency, system, and group are in question. Attempts to use this 
information could provide the user with a false se nse of security that others are receiving his 
messages. Corrupted codeplug blocks  of call IDs, or their associated aliases are considered non-
fatal errors. While the user may be inconvenienced, normal communica tion is still possible.

							6-4Basic Troubleshooting: Operational Error Codes
6.4 Operational Error Codes
During radio operation, the radio performs dynamic tests to determine if the radio is working properly. 
Problems detected during these tests are present ed as error codes on the radio’s display. The 
presence of an error code should prompt a user th at a problem exists and that a Motorola Authorized 
MOTOTRBO  dealer should be contacted. Use Table 6-2 to aid in understanding particular 
operational error codes.

A.3 Piece Parts
Some replacement parts, spare parts, and/or  product information can be ordered directly.  
If a complete Motorola part  number is assigned to the part, it is available from Motorola Radio 
Products and Solutions Organization (RPSO). If no pa rt number is assigned, the part is not normally 
available from Motorola. If the part number is appended with an asterisk, the part is serviceable by 
Motorola Depot only. If a parts list is not included, this generally means that no user-serviceable parts 
are available for that kit or assembly.
Orders for replacement parts, kits and assemblies should be placed directly on Motorolas local 
distribution/dealer organisation or via Motorola Online at:  http://emeaonline.motorola.com
* The Radio Products and Solutions Organization (RPSO) was formerly known as the Radio 
Products Services Division (RPSD) and/or the  Accessories and Aftermarket Division (AAD).
