xvi

User Safety, Training, and General Information

Medical Devices
Pacemakers

The Advanced Medical Technology Association (AdvaMed) recommends that
a minimum separation of 6 inches (15 centimeters) be maintained between a
handheld wireless radio and a pacemaker. These recommendations are
consistent with those of the U.S. Food and Drug Administration.
Persons with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 centimeters) from their
pacemaker when the radio is turned ON.
• not carry the radio in the breast pocket.
• use the ear opposite the pacemaker to minimize the potential for
interference.
• turn the radio OFF immediately if you have any reason to suspect that
interference is taking place.

Hearing Aids

Some digital wireless radios may interfere with some hearing aids. In the event
of such interference, you may want to consult your hearing aid manufacturer
to discuss alternatives.

Other Medical
Devices

If you use any other personal medical device, consult the manufacturer of your
device to determine if it is adequately shielded from RF energy. Your physician
may be able to assist you in obtaining this information.

Driver Safety

Check the laws and regulations on the use of radios in the area where you
drive. Always obey them.
When using your radio while driving, please:
• Give full attention to driving and to the road.
• Use hands-free operation, if available.
• Pull off the road and park before making or answering a call if driving
conditions so require.

User Safety, Training, and General Information

Operational
Warnings

!
WARNING

For Vehicles With an Air Bag
Do not place a portable radio in the area over an air bag or in the air bag deployment
area. Air bags inflate with great force. If a portable radio is placed in the air bag
deployment area and the air bag inflates, the radio may be propelled with great force
and cause serious injury to occupants of the vehicle.

Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive
atmosphere, unless it is a radio type especially qualified for use in such areas as
“Intrinsically Safe” (for example, Factory Mutual, CSA, UL, or CENELEC). Do not
remove, install, or charge batteries in such areas. Sparks in a potentially explosive
atmosphere can cause an explosion or fire resulting in bodily injury or even death.
NOTE:

The areas with potentially explosive atmospheres referred to above
include fueling areas such as below decks on boats, fuel or chemical
transfer or storage facilities, areas where the air contains chemicals or
particles, such as grain, dust or metal powders, and any other area where
you would normally be advised to turn off your vehicle engine. Areas
with potentially explosive atmospheres are often but not always posted.

Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn off your radio when you
are near electrical blasting caps, in a blasting area, or in areas posted: “Turn off twoway radio.” Obey all signs and instructions.

Operational
Cautions

!
Caution

Antennas
Do not use any portable radio that has a damaged antenna. If a damaged antenna comes
into contact with your skin, a minor burn can result.

Batteries
All batteries can cause property damage and/or bodily injury such as burns if a conductive
material such as jewelry, keys, or beaded chains touches exposed terminals. The
conductive material may complete an electrical circuit (short circuit) and become quite
hot. Exercise care in handling any charged battery, particularly when placing it inside a
pocket, purse, or other container with metal objects.

User Safety, Training, and General Information

Intrinsically
Safe Radio
Information
FMRC Approved
Equipment

Anyone intending to use a radio in a location where hazardous concentrations
of flammable materials exist (hazardous atmosphere) is advised to become
familiar with the subject of intrinsic safety and with the National Electric Code
NFPA 70 (National Fire Protection Association) Article 500 (hazardous
[classified] locations).
An Approval Guide, issued by Factory Mutual Research Corporation (FMRC),
lists manufacturers and the products approved by FMRC for use in such
locations. FMRC has also issued a voluntary approval standard for repair
service (“Class Number 3605”).
FMRC Approval labels are attached to the radio to identify the unit as being
FM Approved for specified hazardous atmospheres. This label specifies the
hazardous Class/Division/Group along with the part number of the battery
that must be used. Depending on the design of the portable unit, this FM label
can be found on the back or the bottom of the radio housing. The FM
Approval mark is shown below:
FM
APPROVED

!
WARNING

• Do not operate radio communications equipment in a hazardous atmosphere
unless it is a type especially qualified (for example, FMRC Approved) for such
use. An explosion or fire may result.
• Do not operate an FMRC Approved Product in a hazardous atmosphere if it has
been physically damaged (for example, cracked housing). An explosion or fire
may result.
• Do not replace or charge batteries in a hazardous atmosphere. Contact sparking
may occur while installing or removing batteries and cause an explosion or fire.
• Do not replace or change accessories in a hazardous atmosphere. Contact
sparking may occur while installing or removing accessories and cause an
explosion or fire.
• Do not operate an FMRC Approved Product unit in a hazardous location with the
accessory contacts exposed. Keep the connector cover in place when accessories
are not used.
• Turn a radio off before removing or installing a battery or accessory.
• Do not disassemble an FMRC Approved Product unit in any way that exposes the
internal electrical circuits of the unit.
Radios must ship from the Motorola manufacturing facility with the
hazardous atmosphere capability and FM Approval labeling. Radios will not be
“upgraded” to this capability and labeled in the field.

xix

User Safety, Training, and General Information
A modification changes the unit’s hardware from its original design
configuration. Modifications can only be made by the original product
manufacturer at one of its FMRC-audited manufacturing facilities.

!
WARNING

• Failure to use an FMRC Approved Product unit with an FMRC Approved battery or
FMRC Approved accessories specifically approved for that product may result in
the dangerously unsafe condition of an unapproved radio combination being
used in a hazardous location.
• Unauthorized or incorrect modification of an FMRC Approved Product unit will
negate the Approval rating of the product.

Repair of FMRC
Approved
Products

REPAIRS FOR MOTOROLA PRODUCTS WITH FMRC APPROVAL ARE THE
RESPONSIBILITY OF THE USER.
You should not repair or relabel any Motorola-manufactured communication
equipment bearing the FMRC Approval label (“FMRC Approved Product”)
unless you are familiar with the current FMRC Approval standard for repairs
and service (“Class Number 3605”).
You may want to consider using a repair facility that operates under 3605
repair service approval.

!
WARNING

• Incorrect repair or relabeling of any FMRC Approved Product unit could
adversely affect the Approval rating of the unit.
• Use of a radio that is not intrinsically safe in a hazardous atmosphere could result
in serious injury or death.
FMRC’s Approval Standard Class Number 3605 is subject to change at any time
without notice to you, so you may want to obtain a current copy of 3605 from
FMRC. Per the December 1994 publication of 3605, some key definitions and
service requirements are as follows:

Repair

A repair constitutes something done internally to the unit that would bring it
back to its original condition—Approved by FMRC. A repair should be done in
an FMRC Approved facility.
Items not considered as repairs are those in which an action is performed on
a unit which does not require the outer casing of the unit to be opened in a
manner which exposes the internal electrical circuits of the unit. You do not
have to be an FMRC Approved Repair Facility to perform these actions.

Relabeling

xx

The repair facility shall have a method by which the replacement of FMRC
Approval labels are controlled to ensure that any relabeling is limited to units
that were originally shipped from the Manufacturer with an FM Approval label
in place. FMRC Approval labels shall not be stocked by the repair facility. An
FMRC Approval label shall be ordered from the original manufacturer, as
needed, to repair a specific unit. Replacement labels may be obtained and
applied by the repair facility, provided there is satisfactory evidence that the
unit being relabeled was originally an FMRC Approved unit. Verification may

Introduction

Radio Description

The ASTRO Digital XTS 5000 radios are among the most sophisticated
two-way radios available. The radios are available in the 764-870 MHz
band.
The ASTRO Digital XTS 5000 radio provides improved voice quality
across more coverage area. The digital process, called “embedded
signaling,” intermixes system signaling information with digital voice,
resulting in improved system reliability, and the capability of
supporting a multitude of advanced features.
ASTRO Digital XTS 5000 radios are available in three basic models.
Table 1 describes their basic features.

The ASTRO Digital XTS 5000 radio utilizes Motorola’s FLASHport
technology. FLASHport makes it possible to add software that drives
the radio’s capabilities both at the time of purchase and later on.
Previously, changing a radio’s features and capabilities meant
significant modifications, or buying a new radio. But now, similar to
how a computer can be loaded with different software, the radio’s
features and capabilities can be upgraded with FLASHport software.

Basic Maintenance

2

Introduction

This section of the manual describes preventive maintenance and handling
precautions. Each of these topics provides information vital to the successful
operation and maintenance of your radio.

General
Maintenance

In order to avoid operating outside the limits set by the FCC, it is
recommended that the ASTRO Digital XTS 5000 radio’s reference oscillator be
aligned every time the radio is taken apart, or once per year, whichever comes
first. Periodic visual inspection and cleaning is also recommended.
For XTS 5000R Radios - It is recommended that radio submergibility be
checked annually by qualified service personnel.

Inspection

Check that the external surfaces of the radio are clean, and that all external
controls and switches are functional. A detailed inspection of the interior
electronic circuitry is not needed.

Cleaning

The following procedures describe the recommended cleaning agents and the
methods to be used when cleaning the external surfaces of the radio. External
surfaces include the housing assembly and battery case. These surfaces should
be cleaned whenever a periodic visual inspection reveals the presence of
smudges, grease, and/or grime.
The only recommended agent for cleaning the external radio surfaces is a 0.5%
solution of a mild dishwashing detergent in water.

!
Caution

Cleaning External
Plastic Surfaces

The effects of certain chemicals and their vapors can have
harmful results on certain plastics. Aerosol sprays, tuner
cleaners, and other chemicals should be avoided.

The detergent-water solution should be applied sparingly with a stiff, nonmetallic, short-bristled brush to work all loose dirt away from the radio. A soft,
absorbent, lintless cloth or tissue should be used to remove the solution and
dry the radio. Make sure that no water remains entrapped near the connectors,
cracks, or crevices.

Basic Maintenance

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 highvoltage 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.

!

•

The XTS 5000 radio casting has two vent ports that allow
for pressure equalization in the radio. Never poke these
vents with any objects, such as needles, tweezers, or
screwdrivers. This could create a leak path into the radio
and, in the case of XTS 5000 R radios, the radio’s
submergibility will be lost.

•

The pressure equalization vent is located on the chassis,
just below the battery contact. Never obstruct or cover the
two slots with any object, including a label. Ensure that no
oily substances come in contact with this vent.

•

(XTS 5000 R Radios Only) The XTS 5000 R radio is
designed to be submerged to a maximum depth of 6 feet,
with a maximum submersion time of 4 hours. Exceeding
either maximum limit may result in damage to the radio.

Caution

XTS 5000 R Radios Only

1. If the radio battery contact area has been submerged in water, dry
and clean the radio battery contacts before attaching a battery to
the radio. Otherwise, the water could short-circuit the radio.
2. If the radio has been submerged in water, shake the radio well so
that any water that may be trapped inside the speaker grille and
microphone port can be removed. Otherwise, the water will
decrease the audio quality of the radio.

Analog Mode of
Operation
Receiving

When the radio is receiving (see Figure 2.), the signal comes from the
antenna connector to the Transceiver board, passing through the
antenna switch and the receiver front end. The signal is then filtered,
amplified, and mixed with the first local-oscillator signal, generated by
the voltage-controlled oscillator (VCO).

RX_SSI_ DATA
to VOCON Board

Basic Theory of Operation
The resulting intermediate frequency (IF) signal is fed to the IF
circuitry, where it is again filtered and passed to the Abacus III digital
back-end IC. In the digital back-end IC, the IF signal is mixed with the
second local oscillator to create the second IF at 2.25 MHz. In the backend IC, a bandpass, sigma-delta, analog-to-digital converter then
decodes the second IF signal, and outputs, on the radio’s serial
synchronous interface (SSI) bus, digital audio to the VOCON board.
On the VOCON board, the dual-core processor’s digital-signal
processor (DSP) digitally filters the PCM audio. The DSP decodes the
information in the signal and identifies the appropriate destination
for it.
• For a voice signal, the DSP will route the digital voice data to the
CODEC inside the audio and power supply support IC, for
conversion to an analog signal. The CODEC will then present the
signal to the receive audio pre-amplifier, then to the audio power
amplifier, which drives the speaker.
• For signaling information, the DSP will decode the message and
pass it internally to the microcontrol unit of the dual-core
processor.

Transmitting

When the radio is transmitting (see Figure 3.), microphone audio is
passed through gain stages to the CODEC, where the signal is
digitized. The CODEC passes digital data to the DSP, where preemphasis and low-pass (splatter) filtering are done. The DSP passes this
signal to a digital/analog converter (DAC), where it is reconverted into
an analog signal and scaled for application to the voltage-controlled
oscillator as a modulation signal.

Figure 3. Transceiver Block Diagram (Power and Control Omitted)
Transmitted signaling information is applied to the DSP from the

handles it the same as a voice signal. The DAC output connects to the
synthesizer modulation input. A modulated carrier is provided to the

7

Basic Theory of Operation
transmitter power amplifier, which transmits the signal under
dynamic power control.

ASTRO Mode of
Operation

In the ASTRO (digital) mode of operation, the transmitted or received
signal is limited to a discrete set of frequency deviation levels. The
receiver handles an ASTRO-mode signal identically to an analog-mode
signal, up to the point where the DSP decodes the received data. In the
ASTRO receive mode, the DSP uses a different algorithm to recover
data.
In the ASTRO transmit mode, microphone audio is processed
identically to an analog mode, with the exception of the algorithm the
DSP uses to encode the information. Using this algorithm, transmitter
FM deviation is limited to discrete levels.

Transceiver (XCVR)
Board Basic Theory
of Operation

The receiver front end consists of a preselector filter, low-noise
amplifier, a second preselector, and a mixer. Both preselectors are
varactor-tuned band pass filters, controlled by the microcontroller. See
Table 2 for local oscillator (LO) and first IF information.
Table 2. Local Oscillator and First IF Frequencies
700/800 MHz
LO Frequency Range

741.35-885.65 MHz

First IF Frequency

109.65 MHz

The frequency generation function is performed by three ICs, three
VCOs, and associated circuitry. The reference oscillator IC provides a
frequency standard to the synthesizer. The fractional-N synthesizer
turns on one of three external VCOs, and tunes it to the RX LO or TX
carrier frequency. The VCO buffer and a transistor amplify the signal
to the required power level. The synthesizer is controlled by the
microcontrol unit through a serial peripheral interface (SPI) bus. Most
of the synthesizer circuitry is enclosed in rigid metal cans on the XCVR
board to reduce interference and microphonic effects.
The receiver back end consists of a bandpass crystal filter, input and
output impedance matching networks, and the digital back-end IC.
Final filtering is done digitally in the DSP.
The Abacus III digital back-end IC contains a low-noise amplifier, a
mixer, a variable gain amplifier with integral anti-alias filter, a
bandpass, sigma delta, analog-to-digital converter, and a decimation
filter with a programmable decimation factor. The Abacus III also
contains an automatic gain control (AGC) circuit to provide 25 dB of
continuous gain adjustments. For the second LO, the Abacus III has an
internal, integer-N frequency synthesizer, and an external, discrete
loop filter and voltage-controlled oscillator (VCO). The output of the
Abacus III is digital data on the RX_SSI bus.
The transmitter power amplifier (PA) consists of a driver amplifier IC
and a discrete final-stage. Transmit power is controlled by a power
control IC (PCIC) that monitors the output of a directional coupler

8

Basic Theory of Operation
and adjusts PA control voltages. The transmitter RF signal then passes
through a PIN diode antenna switch and a low-pass harmonic filter,
which connects to the antenna connector.

VOCON Board Basic
Theory of
Operation

The vocoder and controller (VOCON) board comprises the dual-core
processor, which contains the radio’s microcontrol unit and digital
signal processor (DSP) in a single integrated circuit (IC) package, its
memory ICs, an audio and power supply IC, a digital support IC, and
the audio power amplifier. Connected to the VOCON board are the
liquid-crystal display (LCD) board, XCVR board, keypad flex, controls/
universal flex, and (optional) encryption module.
The microcontrol unit portion of the dual-core processor controls
receive/transmit frequencies, power levels, display, and other radio
functions, using either direct logic control or serial communications
paths to the devices. The microcontrol unit executes a stored program
located in the FLASH memory device. Data is transferred to and from
memory by the microcontrol unit data bus. The memory location
from which data is read, or to which data is written, is selected by the
address lines. The microcontrol unit of the dual-core processor
requires a 16.8MHz clock on its CKIH pin and a 32kHz clock on its
CKIL pin.
The DSP portion of the dual-core processor performs signaling and
voice encoding and decoding, as well as audio filtering and volume
control. The DSP performs Private-Line®/Digital Private Line™ (PL/
DPL) encode and alert-tone generation. The DSP transmits preemphasis on analog signals, and applies a low-pass (splatter) filter to
all transmitted signals. The DSP controls squelch, deviation, and
executes receiver and transmitter filtering. The DSP executes a stored
program located in the FLASH memory device.
The DSP of the dual-core processor requires a 16.8MHz clock on the
CKIH pin. Additionally, it requires the 520kHz clock and 8kHz
interrupt signal from the digital support IC, as well as clocks from the
Abacus III digital back-end IC on the XCVR board.
The digital support IC is supplied with a 16.8MHz clock from the
XCVR board. Using this clock, the digital support IC generates a
13MHz clock for the analog and power supply IC, and a 520kHz clock
and an 8kHz interrupt signal for both the DSP and the analog and
power supply IC. Additionally, the digital support IC uses a crystal to
generate the 32kHz clock used by the dual-core processor and audio
and power supply IC. It monitors the position of the on/off switch and
controls the shutdown of the regulators on the audio and power
supply IC. Finally, the digital support IC interfaces to the radio’s 13-pin
universal (accessory) connector. This IC is programmed by the dualcore processor.
The analog and power supply IC has many functions. This IC supplies
most of the voltages used on the VOCON board, while an external
linear regulator supplies 5 volts. It also has microphone audio
amplifiers, switching between internal and accessory microphones,
and the audio CODEC. The audio CODEC performs analog-to-digital
and digital-to-analog conversions on audio signals. It also has an

9

Basic Theory of Operation
analog/digital converter (ADC), which is used to monitor volume
setting and battery voltage. This IC is programmed by the dual-core
processor.
The audio power amplifier (PA) drives the speakers with the received
audio from the analog output of the CODEC from the audio and
power supply IC. The audio PA is sourced from the battery (nominal
value of 7.5 volts). It is programmed by the dual-core processor.

Radio Alignment
Procedures

Introduction

This section describes both receiver and transmitter radio alignment
procedures.

General

A personal computer (PC) and tuner software are required to align the radio.
Refer to the applicable manual for installation and setup procedures for the
software. To perform the alignment procedures, the radio must be connected
to the PC and to a universal test set as shown in Table 4 on page 13.

!
Caution

These procedures should only be attempted by qualified service
personnel. Failure to perform alignment procedures properly may
result in seriously degraded radio or system performance.

Select Tuner from the START menu. To read the radio, use the File ➝ Read
. Figure 5 illustrates how the alignment screens
Device menu or click on
are organized. To access a screen, double-click on the desired screen name in
the Tuner menu.

Radio Alignment Procedures

Softpot

The alignment screens introduce the concept of the “softpot,” an
analog SOFTware-controlled POTentiometer used for adjusting all
transceiver alignment controls.
Do NOT switch radios in the middle of any Alignment
procedure. Always left-click the Close button on the screen to
return to the MAIN menu screen before disconnecting the
C a u t i o n radio. Improper exits from the Alignment screens may leave
the radio in an improperly configured state and result in
seriously degraded radio or system performance.

!

Each alignment screen provides the ability to increase or decrease the
softpot value by using a slider or the screen’s UP/DOWN arrow keys (▲
▼), or by entering the new value from the keyboard. A graphical scale
on the display indicates the minimum, maximum, and proposed value
of the softpot; see Figure 6.

Figure 6. Typical Softpot Screen
Adjusting the softpot value sends information to the radio to increase
(or decrease) the voltage in the corresponding circuit. For example,
left-clicking the UP arrow ▲ on the Reference Oscillator screen
instructs the radio’s microcomputer to increase the voltage across a
varactor in the reference oscillator, which increases the frequency.
In ALL cases, the softpot value is just a relative number corresponding
to a digital-to-analog (D/A) generated voltage in the radio.
Perform the following procedures in the sequence indicated.
NOTE: Some of the following screens may vary depending
upon the radio under test and the version of tuner
software you are using. Refer to the software’s on-line
help.

Radio Alignment Procedures

Radio Information

Figure 7 shows a typical Radio Information screen.

Figure 7. Radio Information Screen

Reference Oscillator
Alignment

Adjustment of the reference oscillator is critical for proper radio
operation. Improper adjustment will result not only in poor operation,
but also in a misaligned radio that will interfere with other users
operating on adjacent channels. For this reason, the reference
oscillator should be checked every time the radio is serviced, or once a
year, whichever comes first. The frequency counter used for this
procedure must have a stability of 0.1 ppm (or better).
NOTE: Reference oscillator alignment is required
replacing (or servicing) the transceiver board.

Transmit Power
Alignment

This alignment procedure adjusts the transmit power of the radio and
must be performed for three different power levels (Low, Mid, and
High), at multiple frequencies for each power level, to allow for proper
alignment across the entire RF band. The RF band is divided into
frequency zones with a calibration point (value) in each zone.
NOTES:
•

The same softpot attenuation value will result in DIFFERENT
radio output power levels at different frequencies.

•

All power measurements are to be made at the antenna port.

•

Transmit Power alignment is required after replacing (or
servicing) the transceiver board.

1. Select the TX Power alignment screen. The screen will indicate the
transmit frequencies to be used. See Figure 9.
2. Left-click the desired frequency field (starting with the highest
frequency shown).
3. Left-click the PTT Toggle button on the screen to make the radio

Transmit Deviation
Balance Alignment

This alignment procedure balances the modulation contributions of
the low- and high-frequency portions of a baseband signal. Proper
alignment is critical to the operation of signalling schemes that have
very low frequency components (for example, DPL) and could result
in distorted waveforms if improperly adjusted.
This procedure needs to be performed at multiple frequencies to allow
for proper alignment across the entire RF band. The RF band is divided
into frequency zones with a calibration point (value) in each zone.
NOTE: This alignment is required after replacing (or servicing)
the VOCON board or the transceiver board.
1. Select the TX Deviation Balance alignment screen. The screen
will indicate the transmit frequencies to be used. See Figure 10.
2. Left-click the desired frequency field (starting with the highest

Multikey
Feature

-

On single-key radios — a short tone.

-

On multikey radios — an alternating tone.

This feature allows the radio to be equipped with multiple encryption keys. It
can support up to two different encryption algorithms simultaneously (e.g.,
DVP-XL and DES-XL).
• Conventional Multikey — The encryption keys can be tied (strapped), on
a one-per-channel basis. In addition, the radio can have operatorselectable keys, operator-selectable indices, and operator-selectable key
erasure. If talkgroups are enabled in conventional, then the encryption
keys are strapped to the talkgroups.
• Trunked Multikey — If the radio is used for both conventional and
trunked applications, strap the encryption keys for trunking on a pertalkgroup or announcement group basis. In addition, a different key can
be strapped to other features; for example, dynamic regrouping, failsoft, or
emergency talkgroup. The radio can have operator-selectable key erasure.

Disassembly/Reassembly Procedures

Ensuring Radio
Submergibility
Introduction

ASTRO XTS 5000 R radio models meet the stringent requirements of
U. S. MIL-STD-810C, Method 512.1, Procedure I; MIL-STD-810D,
Method 512.2, Procedure I; MIL-STD-810E, Method 512.3, Procedure
I; and MIL-STD-810F, Method 512.4, Procedure I, which require the
radio to maintain watertight integrity when immersed in three feet of
water for two hours. XTS 5000R radios shipped from the Motorola
factory have passed vacuum testing and should not be disassembled.
If disassembly is necessary, refer to qualified service personnel and
service shops capable of restoring the watertight integrity of the radio.
It is strongly recommended that maintenance of the radio
be deferred to qualified service personnel and service
shops. This is of paramount importance as irreparable
C a u t i o n damage to the radio can result from service by
unauthorized persons. If disassembly is necessary,
unauthorized attempts to repair the radio may void any
existing warranties or extended performance agreements
with Motorola. It is also recommended that
submergibility be checked annually by qualified service
personnel.

!

If the radio is accidentally dropped in water, shake the radio to remove
the excess water from the speaker grille and microphone port area
before operating; otherwise, the sound may be distorted until the
water has evaporated, or is dislodged from these areas.

General Information

To ensure that the radio is truly a watertight unit, special testing, test
procedures, and specialized test equipment are required. The special
testing involves a vacuum check of the radio and pressure testing
(troubleshooting) for water leaks if the vacuum check fails. The
specialized test equipment is needed to perform the vacuum check and
pressure testing, if required.

Specialized Test
Equipment
Vacuum Pump Kit
NLN9839

The vacuum pump kit includes a vacuum pump with gauge, and a
vacuum hose. An adapter with gasket (NTN9279A), which must be
ordered separately, connects the vacuum hose to the radio’s casting.
The vacuum pump kit is also used on Motorola ASTRO SABER R radios.
The adapter with gasket is the same as that for the ASTRO XTS 3000R
and XTS 3500 R.

Pressure Pump Kit
NTN4265

The pressure pump kit includes a pressure pump with gauge, and a
pressure hose; the pressure pump kit is also used on Motorola ASTRO
SABER R radios. As with the vacuum pump kit above, the NTN9279A
adapter connects the pressure hose to the radio’s casting.

Disassemble the radio according to “Disassembly” on page 48.

Reassembly

Reassemble the radio according to “Reassembly” on page 50. Tighten
all hardware that was loosened or removed.

!

Do not reassemble the radio without first performing the
following preliminary inspection procedure.

Caution
1. Remove the main seal o-ring from the casting.
2. Inspect the seal area around the casting for foreign material that
might prevent the main seal o-ring from sealing properly.
3. Install a new main seal o-ring; discard the old o-ring.
4. Reassemble the housing.

!

The main seal o-ring should not be visible when looking at
the back side of the radio. If the seal is visible, it is
improperly installed.

Caution

Vacuum Test

Refer to the exploded view diagrams and parts lists in this manual.

General

The vacuum test uses a vacuum pump and gauge. The pump creates a
vacuum condition inside the radio, and the gauge monitors the radio
for a stable vacuum reading; that is, checking for a properly sealed,
watertight unit. Before starting the vacuum test:
• Remove the battery.
• Remove the universal connector cover to expose the universal
connector.

Conducting the Test

1. Attach the vacuum hose to the vacuum pump. Check the pump
and hose for leaks by blocking off the open end of the hose and
operating the pump a few times. The actual reading of the gauge
at this point is not important; it is important that the gauge
pointer remains steady, indicating no vacuum leaks in the pump.
2. Remove the vacuum test port using a pair of needle-nosed pliers
and pulling upward.
3. Ensure that a rubber gasket is attached to the hose-to-casting
adapter. Screw the adapter into the tapped hole in the casting.

54

Disassembly/Reassembly Procedures
4. Attach the open end of the hose to the adapter.
5. Place the radio on a flat surface with the casting facing upward.
Place two or three drops of water on each slot of the label (62)
that protects the vent port seal (61) on the casting. This will
ensure that no air goes through the seal.
6. Operate the pump a few times until the gauge indicates 5 in. Hg;
do not pull more than 7 in. Hg of vacuum on the radio.
Operate the pump again until the gauge indicates 6 in. Hg.
7. Observe the gauge for approximately 1 minute.
•

If the needle falls 1 in. Hg or less (for example, from 6 in. Hg
to 5 in. Hg), then the radio has passed the vacuum test and is
approved for submergibility. No additional testing will be
required.

•

If the needle falls more than 1 in. Hg (for example, from 6 in.
Hg to less than 5 in. Hg), then the radio has failed the vacuum
test and the radio might leak if submerged. Additional
troubleshooting of the radio will be required; complete this
procedure, then go to the “Pressure Test” section of this
manual.

8. Dry the water from the slots on the label (62) that protects the
vent port seal to allow the radio to equalize. The pressure should
drop slowly to “0.”
9. Remove the vacuum hose and adapter from the radio.
10. Install the vacuum test port plug by pressing it in, ensuring that
the plug sits flat all around the edges and it is flush with the
casting.

Pressure Test

Refer to the exploded view diagrams and parts lists in this manual.

General

Pressure testing the radio is necessary only if the radio has failed the
vacuum test. Do not perform the pressure test until the vacuum test
has been completed. Pressure testing involves creating a positive
pressure condition inside the radio, submerging the radio in water,
and observing the radio for a stream of bubbles (leak). Since all areas
of the radio are being checked, observe the entire unit carefully for the
possibility of multiple leaks before completing this test.

Conducting the Test

1. Remove the vacuum test port using a pair of needle-nosed pliers
and pulling upward.
2. Screw the adapter (with gasket) into the tapped hole in the
casting.
3. Attach one end of the pressure hose to the adapter and the other
end to the pressure pump.
4. Cover the vent port seal (61) and label (62) on the back of the
casting with your thumb. This will prevent air from going
through the seal. Keep the vent port covered with your thumb
until the test is complete (through step 8).
5. Operate the pump until the gauge reads approximately 1 psig.

55

Disassembly/Reassembly Procedures

!

Pressure any greater than 1 psig may push air around the
main seal.

Caution
6. Maintain the pressure at 1 psig and submerge the radio into a
water-filled container. Keep the vent port covered with your
thumb while the radio is submerged.
7. Watch for any continuous series of bubbles. A stream of bubbles
indicates a sign of leakage.
NOTE:

Some air entrapment may cause the accumulation
of bubbles, especially in the grille area, but the
bubbles should not be continuous.

8. Note all of the seal areas that show signs of leakage. Pinpoint the
problem(s) to one (or more) of the following areas:
• Housing
• Antenna bushing seal
• Controls seal
• Frequency switch, toggle, and on/off/volume control switch
• Main seal
• Battery contact and battery contact seal
• Keypad
9. Remove the radio from the water container, remove your thumb
from the vent port seal, and dry the radio thoroughly. Be
especially careful to dry the area around the main seal to prevent
contamination of the internal electronics while the unit is open.

!

To avoid equipment damage, keep the area around the port
seal dry by ensuring that there is no water around the
casting’s vacuum port.

Caution
10. Remove the adapter and pressure hose added in steps 1 and 2,
above.
11. Install the vacuum test port plug by pressing it in, ensuring that
the plug sits flat all around the edges and it is flush with the
casting.
12. Inspect the vent port seal (61) to ensure that the seal behind the
label’s (62) two slots has not been punctured. If it has been
punctured, the seal and the label must be replaced.

Troubleshooting
Leak Areas

Before repairing any leak, read all applicable area repair paragraphs.
This will help to eliminate unnecessary disassembly and reassembly of
a radio with multiple leaks. Troubleshoot only the faulty seal areas
listed in “Pressure Test” on page 55, and, when multiple leaks exist, in
the order listed.
NOTE:

56

Before reassembling the radio, always install a new
main seal o-ring, and new seals in the defective area.

Basic Troubleshooting

Introduction
to This Section

9

This section of the manual contains troubleshooting charts and error codes
that will help you to isolate a problem. Level one and two troubleshooting will
support only radio alignment, programming, battery replacement, and knob
replacement, and circuit board replacement.
Component-level service information can be found in the “ASTRO Digital
XTS 5000 Portable Radios Detailed Service Manual,” Motorola publication
number 68P81094C31.

Power-Up
Error Codes

When the radio is turned on (power-up), the radio performs self-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’s display.
For non-display radios, the problem will be presented at power-up by a single,
low-frequency tone. The radio should be sent to the depot if cycling power
and reprogramming the code plug do not solve the problem. The presence of
an error 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; non-fatal errors will not. Use Table 17 on page 64 to aid in
understanding particular power-up error code displays.
