VI. Patent And Software Provisions
MOTOROLA will defend, at its own expense, any suit brought against the end user purchaser to the
extent that it is based on a claim that the Product or parts infringe a United States patent, and
MOTOROLA will pay those costs and damages finally awarded against the end user purchaser in
any such suit which are attributable to any such claim, but such defense and payments are
conditioned on the following:
A. that MOTOROLA will be notified promptly in writing by such purchaser of any notice of such
claim;
B. that MOTOROLA will have sole control of the defense of such suit and all negotiations for its
settlement or compromise; and
C. should the Product or parts become, or in MOTOROLA’s opinion be likely to become, the
subject of a claim of infringement of a United States patent, that such purchaser will permit
MOTOROLA, at its option and expense, either to procure for such purchaser the right to
continue using the Product or parts or to replace or modify the same so that it becomes
noninfringing or to grant such purchaser a credit for the Product or parts as depreciated and
accept its return. The depreciation will be an equal amount per year over the lifetime of the
Product or parts as established by MOTOROLA.
MOTOROLA will have no liability with respect to any claim of patent infringement which is based
upon the combination of the Product or parts furnished hereunder with software, apparatus or
devices not furnished by MOTOROLA, nor will MOTOROLA have any liability for the use of ancillary
equipment or software not furnished by MOTOROLA which is attached to or used in connection with
the Product. The foregoing states the entire liability of MOTOROLA with respect to infringement of
patents by the Product or any parts thereof.
Laws in the United States and other countries preserve for MOTOROLA certain exclusive rights for
copyrighted MOTOROLA software such as the exclusive rights to reproduce in copies and distribute
copies of such Motorola software. MOTOROLA software may be used in only the Product in which
the software was originally embodied and such software in such Product may not be replaced,
copied, distributed, modified in any way, or used to produce any derivative thereof. No other use
including, without limitation, alteration, modification, reproduction, distribution, or reverse
engineering of such MOTOROLA software or exercise of rights in such MOTOROLA software is
permitted. No license is granted by implication, estoppel or otherwise under MOTOROLA patent
rights or copyrights.

Chapter 1 Introduction
1.1 General
This manual includes all the information needed to maintain peak product performance and
maximum working time for the ASTRO XTS 5000 radio. This detailed level of service (component
level) is typical of the service performed by some service centers, self-maintained customers, and
distributors.
Use this manual in conjunction with the ASTRO XTS 5000 VHF/UHF Range 1/700–800 MHz Digital
Portable Radios Basic Service Manual (Motorola part number 6881094C28), which can help in
troubleshooting a problem to a particular printed circuit (PC) board.
Conduct the basic performance checks outlined in the basic service manual first to verify the need to
analyze the radio and to help pinpoint the functional problem area. In addition, you will become
familiar with the radio test mode of operation, which is a helpful tool. If any basic receive or transmit
parameters fail to be met, the radio should be aligned according to the radio alignment procedure.
Included in other areas of this manual are functional block diagrams, detailed theory of operation,
troubleshooting charts and waveforms, schematics, and parts lists. You should become familiar with
these sections to aid in determining circuit problems. Also included are component location diagrams
to aid in locating individual circuit components and some IC diagrams, which identify some
convenient probe points.
“Chapter 3, Theory of Operation,” on page 3-1, contains detailed descriptions of the operations of
many circuits. Once you locate the problem area, review the troubleshooting flowchart for that circuit
to fix the problem.

Chapter 2 Radio Power
This chapter provides a detailed circuit description of the power distribution of an ASTRO XTS 5000
radio.
2.1 General
In the ASTRO XTS 5000 radio, power (B+) is distributed to two boards: the transceiver (RF) board
and the VOCON board (see Figure 2-1 on page 2-2 for UHF Range 1 (R1) and 700–800 MHz, and
Figure 2-2 on page 2-2 for VHF). In the case of a secure model radio, B+ is also supplied to the
encryption module.
Power for the radio is provided through a battery supplying a nominal 7.5 Vdc directly to the
transceiver. The following battery types and capacities are available:

2-2 Radio Power: General
Figure 2-1. DC Power Distribution—UHF Range 1 and 700–800 MHz Radios
Figure 2-2. DC Power Distribution—VHF Radios
B+ from the battery is electrically switched to most of the radio, rather than routed through the On/
Off/volume control knob, S1. The electrical switching of B+ supports a keep-alive mode. Under
software control, even when the On/Off/volume control knob has been turned to the Off position,
power remains on until the MCU completes its power-down, at which time the radio is physically
powered down.

Radio Power: DC Power Routing—Transceiver Board 2-3
2.2 DC Power Routing—Transceiver Board
NOTE: Refer to Table 8-1, “List of Transceiver Schematics and Board Overlays,” on page 8-1 for a
listing of schematics showing the transceiver board DC power routing components.
Connector J1, the B-plus assembly, connects the battery to the transceiver board. Capacitors C1,
C2, and C3 provide protection against momentary breaks at the B-plus connector due to contact
bounce when the radio is dropped.
UHF R1 and 700–800 MHz: Components C5, E4, C7, and E1 form a power-line filter for signal
RAWB+, which supplies battery voltage to the transmitter PA.
VHF: Component E1 forms a power-line filter for signal RAWB+, which supplies battery voltage to
the transmitter PA.
Transistor Q1, controlled by signal SWB+ (SB+ for VHF) from the VOCON board, turns on XB+,
which supplies to the 5-V linear regulator and TX_ALC block.
Fuse F901 and filter C11, L1, C10 (C14, L1, C13 for VHF) supply fused B-plus to the VOCON board.
In turn, the VOCON board supplies VSW1, regulated 3.8 Vdc, from the Global Control Audio and
Power (GCAP) switching regulator to the XCVR. Switch Q99 (Q503 for VHF), controlled by SWB+,
turns on V38 to the XCVR 3-V linear regulators. The XCVR regulated power supplies are
summarized in Table 2-3.
2.3 DC Power Routing—VOCON Board
NOTE: Refer to Table 8-2, “List of VOCON Schematics and Board Overlays,” on page 8-1 for a listing
of schematics showing the VOCON board DC power routing components.
Raw B+, or unswitched B+, (UNSW_B+) is routed to connector P1 on the transceiver board, and
then on to P201 on the VOCON board. Here the UNSW B+ is forwarded to the radio’s control top
On/Off/volume knob through connector J101 and a flex circuit, as well as to regulator U505 (VCC5).
The On/Off/volume knob controls B+SENSE to Q502, which in turn controls Q501. Transistor Q501
is a solid-state power switch that provides SW B+ to the VOCON board, the audio PA, the GCAP II
IC (via GCAP_B+), and back to the transceiver board.
In the case of a secure radio model, SW B+ and UNSW B+ are also supplied to the encryption
module through connector J701.

2-4 Radio Power: DC Power Routing—VOCON Board
Transistor Q501 is also under the control of the microcontroller unit (MCU) via Vref from U501. This
allows the MCU to follow an orderly power-down sequence when it senses that B+SENSE is off. This
sense is provided through MECH_SW_BAR (inverted B+SENSE, see Q508).
The digital circuits in the VOCON board are powered from regulators located in the GCAP II IC
(U501), an external 5 Vdc regulator (VCC5, U505), and an external 1.55 Vdc regulator (VSW_1.55V,
on NNTN4717 VOCON kit only). The GCAP II IC provides three supplies: VSW1, VSW2, and V2.
These regulators are software programmable. Table 2-4 lists the supply voltages and the circuits that
use these voltages.

Chapter 4 Troubleshooting Procedures
The purpose of this chapter is to aid in troubleshooting problems with the ASTRO XTS 5000 radio. It
is intended to be detailed enough to localize the malfunctioning circuit and isolate the defective
component. It also contains a listing of service tools recommended for PC board repair at the
component level.
4.1 Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices,
are used in this family of radios. While the attributes of these devices are many, their characteristics
make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges.
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special
precautions must be taken to prevent device damage during disassembly, troubleshooting, and
repair. Handling precautions are mandatory for this radio, and are especially important in low-
humidity conditions. DO NOT attempt to disassemble the radio without observing the following
handling precautions.
1. Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back
loose-hanging neckties.
3. Store and transport all static-sensitive devices in ESD-protective containers.
4. Disconnect all power from the unit before ESD-sensitive components are removed or inserted
unless otherwise noted.
5. Use a static-safeguarded workstation, which can be accomplished through the use of an anti-
static kit (Motorola part number 01-80386A82). This kit includes a wrist strap, two ground
cords, a static-control table mat and a static-control floor mat.
Most of the ICs are static sensitive devices. Do not attempt to
disassemble the radio or troubleshoot a board without first
referring to the following Handling Precautions section.

Troubleshooting Procedures: Voltage Measurement and Signal Tracing 4-3
4.3 Voltage Measurement and Signal Tracing
It is always a good idea to check the battery voltage under load. This can be done by checking the
OPT_B+_VPP pin at the side connector (pin 4). The battery voltage should remain at or above
7.0 Vdc. If the battery voltage is less than 7.0 Vdc, then it should be recharged or replaced as
necessary prior to analyzing the radio.
In most instances, the problem circuit may be identified using a multimeter, an RF millivoltmeter,
oscilloscope (preferably with 100 MHz bandwidth or more), and a spectrum analyzer.

Troubleshooting Procedures: Power-Up Self-Check Errors 4-5
4.5 Power-Up Self-Check Errors
Each time the radio is turned on, the MCU and DSP perform a series of internal diagnostics. These
diagnostics consist of checking such programmable devices as the FLASH ROMs, the EEPROM,
and SRAM devices.
Problems detected during the power-up self-check routines are presented as error codes on the
radio’s display. For non-display radios, the problem is presented at power up by a single, low-
frequency tone. Table 4-3 lists possible error codes, a description of each error code, and a
recommended corrective action.

01/02 This non-fatal error will likely recover if the radio’s power is cycled. In the event that this
does not resolve the issue, the radio should be reflashed. As a last resort, the FLASH
ROM U402 should be replaced.
01/12 The radio should be sent to the depot for reflashing of the security codeplug.
01/20 Cycling radio power should resolve this issue.
01/22 The radio should be sent to the depot for reflash of the tuning codeplug followed by
retuning of the radio.
01/81 The radio should be sent to the depot for reflashing of the host code.
01/82 The radio should be sent to the depot for reflashing of the radio codeplug.
01/88 Reflashing of the radio should first be performed. If this fails to resolve the issue, then
replacement of the SRAM U403 is necessary.
01/90 Cycle power to radio. Continued failure indicates a likely IC failure (GCAP, PCIC,
FLIPPER, ABACUS). In this event, radio should be sent to the depot for isolation and
repair of the problem IC.
01/92 The radio should be sent to the depot for reprogramming of the security codeplug.
01/93 The radio should be sent to the depot for reflashing of the host code.
01/98 Send radio to the depot for replacement of the SRAM U403.
01/A2 The radio should be sent to the depot for reflashing of the tuning codeplug followed by

Chapter 5 Troubleshooting Charts
This section contains detailed troubleshooting flowcharts. These charts should be used as a guide in
determining the problem areas. They are not a substitute for knowledge of circuit operation and
astute troubleshooting techniques. It is advisable to refer to the related detailed circuit descriptions in
the theory of operation sections prior to troubleshooting a radio.
5.1 List of Troubleshooting Charts
Most troubleshooting charts (see Table 5-1) end up by pointing to an IC to replace. It is not always
noted, but it is good practice to verify supplies and grounds to the affected IC and to trace
continuity to the malfunctioning signal and related circuitry before replacing any IC. For
instance, if a clock signal is not available at a destination, continuity from the source IC should be
checked before replacing the source IC.

NOTE: Since the failure of a critical voltage supply might cause the radio to automatically power
down, supply voltages should first be probed with a multimeter. If all the board voltages
are absent, then the voltage test point should be retested using a rising-edge-triggered
oscilloscope. If the voltage is still absent, then another voltage should be tested using the
oscilloscope. If that voltage is present, then the original voltage supply in question is
defective and requires investigation of associated circuitry.

This failure relates only to secure-
equipped radios and indicates a
failure to load key with the KVL
indicated by the message
"KEYFAIL" and key-fail tone.
Typical failure modes would be:
1) Open between universal
connector uC which places radio
in Keyload mode.
2) Use of wrong KVL or KVL cable
for XTS 5000 radio.
3) Failure of secure module.

This failure relates only to secure-equipped
radios and indicates a power-up self-test failure
for the secure module. More specifically this
failure indicates a failure in communications
between the DSP and secure module. The
secure module is not considered field repairable
so troubleshooting is limited to verifying a
problem with the module and replacing.
Typical failure modes would be:
1) Open between secure module and VOCON
board at J701.
2) Failure of the SSI bus that the DSP uses to
communicate with the secure module.
3) Failure to get proper supplies and grounds
to J701.
