Introduction: Radio Description

Radio Description
The ASTRO APX 7000 radios are among the most sophisticated two-way radios available. These
dual band radios are capable of operating in both VHF (136–174 MHz) and 764–870 MHz frequency
bands, UHF1 (380–470 MHz) and 764–870 MHz frequency bands, VHF (136–174 MHz) and UHF1
(380–470 MHz) frequency bands, UHF1 (380–450 MHz) and UHF2 (450–520 MHz) frequency
bands, UHF2 (450–520 MHz) and 764–870 MHz frequency bands, and, VHF (136–174 MHz) and
UHF2 (450–520 MHz) frequency bands.
The ASTRO APX 7000 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 APX 7000 radios are available in two configurations – Top Display and Dual Display.
Table 1-1 describes their basic features.

FLASHport®
The ASTRO APX 7000 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.

Chapter 2 Basic Maintenance

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

2.1

General Maintenance
In order to avoid operating outside the limits set by the FCC, we recommend that you align the
ASTRO APX 7000 radio’s reference oscillator every time the radio is taken apart, or once per year,
whichever comes first. Checking this parameter when the product is placed in service is especially
important if the product has been in storage for a significant period of time (6 months or more)
between being shipped from the factory and commissioned for service. (See Section “6.5.1
Reference Oscillator Alignment” on page 1:6-4). Periodic visual inspection and cleaning is also
recommended.
For APX 7000 R (Ruggedized) Radios – Radio submergibility should be checked annually by
qualified service technicians.

2.1.1

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.

2.1.2

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.

Use all chemicals as prescribed by the manufacturer. Be sure to follow all
safety precautions as defined on the label or material safety data sheet.
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, non-metallic, 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.

Sec 1: 2-2

2.2

Basic Maintenance: Handling Precautions

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 lowhumidity conditions.

• The APX 7000 radio has a vent port that allows for pressure equalization
in the radio. Never poke this vent with any objects, such as needles,
tweezers, or screwdrivers. This could create a leak path into the radio and,
in the case of APX 7000 R radios, the radio’s submergibility will be lost.
• The pressure equalization vent is located under the main speaker grille
near the top left side. Never obstruct or cover the small opening on the top
left with any object, including a label. Ensure that no oily substances come
in contact with this vent.
• (APX 7000 R Radios Only) The APX 7000 R radio is designed to be
submerged to a maximum depth of six (6) feet, with a maximum
submersion time of 2 hours per U.S. MIL-STD. Exceeding either
maximum limit may result in damage to the radio. For specific U.S.
MIL-STD details, see Section “8.10 Ensuring Radio Submergibility” on
page 1:8-39.

2.2.1

APX 7000 R Radios Only
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.
If the radio has been submerged in water, shake the radio briskly so that any water that is trapped
inside the speaker grille and microphone port can be removed. Otherwise, the water will decrease
the audio quality of the radio.

Chapter 3 Basic Theory of Operation

This chapter discusses the basic operational theory of the ASTRO APX 7000 radio, which is a
wideband, synthesized radio available in the VHF (136–174 MHz), UHF1 (380–470 MHz),
UHF2 (450–520 MHz), 764 to 870 MHz, VHF/764 to 870 MHz, UHF1/764 to 870 MHz, VHF/UHF1,
UHF1/UHF2, UHF2/764 to 870 MHz and VHF/UHF2, frequency bands.
All ASTRO APX 7000 radios are capable of both analog operation (12.5 kHz or 25 kHz bandwidths),
ASTRO mode (digital) operation (12.5 kHz only) and X2-TDMA mode (25 kHz only).

3.1

Analog Mode of Operation
This section provides an overview of the analog mode receive and transmit theory of operation.

3.2.1

Receiving
The RF signal is received at the antenna and is routed through the Auxiliary and Multi Switch (SP3T)
ICs. The latter contains a switchable attenuator that is enabled at predetermined RF power
thresholds present at the antenna port. The output of the Multi-switch IC is applied to the first SPST
band select switch to select either VHF or 700–800 bands (see Figure 3-3), UHF1 or 700–800 bands
(see Figure 3-4), VHF or UHF1 bands (see Figure 3-5), UHF1 or UHF2 bands (see Figure 3-6),
UHF2 or 700–800 bands (see Figure 3-7) and VHF or UHF2 bands (see Figure 3-8).

Basic Theory of Operation: Analog Mode of Operation

3.2.1.1 GPS
The GPS architecture employs a single chip GPS receiver which decodes GPS signals at
1575.42 MHz. It is capable of producing a final position solution including full tracking and data
decode capability. The GPS receiver will operate in the autonomous mode only.
The GPS signal is tapped at the antenna port via a series resonant network which provides a very
low capacitive load to the transceiver. The signal is routed though a GPS LNA and its output is
applied to the RF-Controller interface connector where it is eventually routed to the expansion board
for processing by the GPS IC.
The GPS receiver is setup in an autonomous one track always (OTA) mode, also known as
continuous navigation. This means the GPS will continuously track satellites for as long as the radio
is powered to ensure the best possible accuracy. In the event the radio loses visibility of the satellites
due to terrain or environmental factors such as driving through a tunnel or entering a building, the
GPS will temporarily lose its position fix. A power savings algorithm will then cycle the GPS in and
out of a sleep mode at approximately 90 second intervals until the radio has moved back into an
environment where GPS signals are present.
The user will be able to view the current latitude, longitude, and time/date stamp on the radio’s
display. The radio can also be configured to send its location to the system at predetermined
intervals (LRRP). Depending on system options, the user may be able to enable/disable the GPS
receiver.

From the first band select switch, a VHF signal is routed to the first pre-selector filter followed by an
LNA and a second pre-selector filter. Both filters are discrete and fixed designs and are used to band
limit the incoming energy and suppress known spurious responses such as Image and the ½ IF spur.
The output of the second pre-selector filter is applied to the RF port of the Mixer IC via a second
VHF/700,800 or VHF/UHF1, or VHF/UHF2 band select switch. The Mixer IC is also excited by a
Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz
intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF
amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

Sec 1: 3-7

3.2.1.3 700/800 MHz Front-End
From the first band select switch, a 700 MHz or 800 MHz band signal is routed to a second band
SPST switch which selects the 700 or the 800 band signal and routes it to the appropriate first
pre-selector filter. A third band select switch selects the output of the appropriate filter and applies it
to an LNA followed by a similar pre-selector filter/ band-select switch circuit. The signal is then routed
to second LNA whose output is applied to a discrete image filter. Both preselector filters are Surface
Acoustic Wave designs used to band limit the received energy and suppress known spurious
responses such as Image and the ½ IF spur. The output of the discrete image filter is applied to the
RF port of the Mixer IC via a second VHF/700,800 or UHF1/700,800 or UHF2/700,800 band select
switch. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert
the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed
through a crystal filter and IF amplifier which drives the input of the Abacus 3 Analog to Digital
Converter IC (AD9864).
3.2.1.4 UHF1 Front-End
From the first band select switch, a UHF1 signal is routed to the first pre-selector filter followed by an
LNA and a second pre-selector filter. Both filters are discrete and tunable designs and are used to
band limit the incoming energy and suppress known spurious responses such as Image spur. The
output of the second pre-selector filter is applied to the RF port of the Mixer IC via a second
UHF1/700,800 or UHF1/VHF or UHF1/UHF2 band select switch. The Mixer IC is also excited by a
Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz
intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF
amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).
3.2.1.5 UHF2 Front-End
From the first band select switch, a UHF2 signal is routed to the first pre-selector filter followed by a
Low Noise Amplifier (LNA) and a second pre-selector filter. Both filters are discrete and tunable
designs and are used to band limit the incoming energy and suppress known spurious responses
such as Image spur. The output of the second pre-selector filter is applied to a discrete Low Pass
Filter (LPF). The output of the LPF is applied to the RF port of the Mixer IC via a second
UHF2/700,800 or UHF1/UHF2 or VHF/UHF2 band select switch. The Mixer IC, is driven by a Local
Oscillator (LO) signal generated by the Trident synthesizer IC, at the LO port to down-convert the RF
signal to a 109.65 MHz intermediate frequency (IF). It is a passive, high linearity design with
balanced inputs at the RF and IF ports and internal LO buffer. The down converted IF signal is
passed through a 3-pole crystal filter, and an IF amplifier, which drives the input of the Analog to
Digital Converter IC.
3.2.1.6 Analog To Digital Converter
The ADC IC's front end down converts the first IF to a second IF, a 2.25 MHz signal. The second IF
is sampled at 18 MHz, a signal generated by an integrated clock synthesizer. The sampled signal is
decimated by a factor of 900 to 20 kHz and converted to SSI format at the ADC's output. The Serial
Synchronous Interface (SSI) serial data waveform is composed of a 16 bit in-phase word (I) followed
by a 16 bit Quadrature word (Q). A 20 kHz Frame Synch and a 1.2 MHz clock waveform are used to
synchronize the SSI IQ data transfer to the Digital Signal Processor IC (OMAP) for post-processing
and demodulation.

Transmitting
When the radio is transmitting, microphone audio is digitized and then processed by the DSP and
sent to the Trident IC (see Figure 3-10 to Figure 3-15) via the SSI interface. The Trident IC
processes the SSI data for application to the voltage controlled oscillator as a modulation signal.

3.2.2.1 VHF Transmit
Once a VHF frequency for transmit has been selected, the Trident IC and its accompanying logic
circuitry enable the correct voltage controlled oscillator which then generates the desired transmit
frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An
RF switch then routes the signal to the VHF Driver amplifier and then to the discrete final stage. The
signal is then filtered by a harmonic filter and passed through a RF switch into a directional coupler.
The Log Amp power detector monitors the output of the directional coupler and adjusts the control
voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single Pole
DoubleThrow (SP2T) RF switch which can route the power to the main antenna or to the Universal
Connector port of the radio.
3.2.2.2 700/800 MHz Transmit
Once a 700/800 MHz frequency for transmit has been selected, the Trident IC and its accompanying
logic circuitry enable the correct voltage controlled oscillator which then generates the desired
transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the
signal. An RF switch then routes the signal to the 700/800 MHz Driver amplifier and then to the
discrete final stage. The signal is then filtered by a harmonic filter and passed through a RF switch
into a directional coupler. The Log Amp power detector monitors the output of the directional coupler
and adjusts the control voltages to the driver amplifier and the discrete final. Finally, the RF signal
comes to a Single Pole Double Throw (SP2T) RF switch which can route the power to the main
antenna or to the Universal Connector port of the radio.
3.2.2.3 UHF1 Transmit
Once a UHF frequency for transmit has been selected, the Trident IC and its accompanying logic
circuitry enable the correct voltage controlled oscillator which then generates the desired transmit
frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An
RF switch then routes the signal to the UHF1 Driver amplifier and then to the discrete final stage.
The signal is then filtered by a harmonic filter and passed through a RF switch into a directional
coupler. The Log Amp power detector monitors the output of the directional coupler and adjusts the
control voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single
Pole DoubleThrow (SP2T) RF switch which can route the power to the main antenna or to the
Universal Connector port of the radio.
3.2.2.4 UHF2 Transmit
Once a UHF frequency for transmit has been selected, the Trident IC and its accompanying logic
circuitry enable the correct voltage controlled oscillator which then generates the desired transmit
frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An
RF switch then routes the signal to the UHF2 Driver amplifier and then to the discrete final stage.
The signal is then filtered by a harmonic filter and passed through a RF switch into a directional
coupler. The Log Amp power detector monitors the output of the directional coupler and adjusts the
control voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single
Pole DoubleThrow (SP2T) RF switch which can route the power to the main antenna or to the
Universal Connector port of the radio.

3.3

Digital (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.

Sec 1: 3-12

3.4

Basic Theory of Operation: Controller Section

Controller Section
The controller section (see Figure 3-16) comprises of five functional sections that are split among
three boards, which are the VOCON, EXPANSION and BLUETHOOTH OPTION boards. The main
functional section consists of a dual core ARM and DSP controller, an encryption processor (MACE),
Flash memory, and a Double Data Rate Synchronous Dynamic Random Access Memory (DDR
SDRAM). The Power and Clocks section includes a power management IC (MAKO) and various
external switching regulators, and two clock sources (12 MHz and 24.576 MHz) from which all other
controller digital clocks are derived. The Audio section has a CODEC and a class-D audio power
amplifier that provides the radio with a multiple microphone, multiple speaker design. The User
Interface section provides communication and control to the top and main Liquid Crystal Displays
(LCD) on the radio, as well as a keypad and a side connector interface conforming to Universal
Connector specifications. The Expansion Memory, GPS and Bluetooth section comprises of a Micro
SD memory interface, Global Positioning Satellite (GPS) processor, and an Option Board for radio
feature upgrades.

Figure 3-16. Controller Block Diagram
The ARM controller core of the OMAP processor handles the power up sequence of all devices,
including firmware upgrades, and all operating system tasks that are associated with FLASH and
SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to
store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into
SDRAM (32 MB) for execution. The ARM and DSP core jointly control and configure audio, wireless
and RF devices linked to the Serial Peripheral Interface (SPI) and Synchronous Serial Interface
(SSI) buses to enable radio FM and optional wireless communication protocols. For encryption, a
separate ARM processor is used (MACE) to encode and decode encryption packets coming in from
the main OMAP processor through the SSI interface. Its firmware is flashed via the main processor
during an upgrade request to its internal FLASH memory.

Basic Theory of Operation: Controller Section

Sec 1: 3-13

The power and most clocks to the controller devices are provided by the MAKO IC and external
switching and linear regulators on board. A Complex Programmable Logic Array (CPLD) IC divides
the 24.576 MHz clock from MAKO to source OMAP's 32 kHz Real Time Clock, and MACE's 4 MHz
main clock. OMAP's main clock is supplied externally from an on board 12 MHz crystal.
The radio has two internal microphones and two internal speakers, as well as available microphone
and speaker connections for external accessories. The main external speaker is located opposite to
the main display and keypad of the radio. It can deliver a rated power of 1W on a ~4 Ohms speaker,
while the smaller "data" speaker can only deliver 0.5 W of power on a load of 16 Ohms. Both internal
and external microphones use the CODEC's AD to deliver digital audio samples to the DSP
controller. The main speaker is driven by the class D PA on the expansion board, while the data and
external speakers are driven by the AB type PA on MAKO. Both speaker paths use the CODEC for
volume control and to convert audio from digital to analog.
The user interface block consists of a top and main or "data side" display, a keypad, top controls and
the accessory side connector. The side connector (Universal Connector) provides audio, USB,
RS232 and RF communication for accessories. All signals to and from the connector go through the
internal expansion board before reaching the microcontroller and other devices on the main board.
The radio also has an expansion bay for a Micro SD memory card, a Global Positioning System
(GPS) interface, and an bluetooth slot for radio feature upgrades. The memory card can be inserted
on the bay near the battery connector of the radio. The bluetooth slot of the radio is available
internally to the radio, and it is not hot swappable by the user. The bluetooth slot is available through
a connector directly linked to the main controller board.

Chapter 6 Radio Alignment Procedures

This chapter describes both receiver and transmitter radio alignment procedures.

6.1

Test Setup
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. The radio alignment test setup is
shown in Figure 6-1.

Radio Alignment Procedures: Tuner Main Menu

Tuner Main Menu
Select Tuner from the START menu by clicking Start › Program Files › Motorola ›
ASTRO 25 Products › ASTRO 25 Tuner. To read the radio, use the File › Read Device menu or
click on
. Figure 6-2 illustrates how the alignment screens are organized. To access a
screen, double-click on the desired screen name in the Tuner menu.

Figure 6-2. Tuner Software Main Menu
IMPORTANT:

6.3

Tuning should follow the order of the Tuning tree view in descending
order from top to bottom

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
radio. Improper exits from the alignment screens might 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 by entering the new value from the keyboard directly into the box. The slider bar indicates
the current softpot value; see Figure 6-3.

Radio Alignment Procedures: Softpot

Sec 1: 6-3

Figure 6-3. 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 spin button in the New Softpot Value scroll
box 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 online help.

When keying the radio during a test, always transmit into a
dummy load.

Transmitter Alignments

6.5.1

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). Also, checking this parameter when the
product is placed in service is especially important if the product has been in storage for a significant
period of time (6 months or more) between being shipped from the factory and commissioned for
service.
NOTE: Reference oscillator alignment is required after replacing (or servicing) the transceiver board.
This test can be done with either the R-2670 Communication Analyzer or the 8901_ Modulation
Analyzer.
• Initial setup using the R-2670 Communication Analyzer:
- RF Control: MONITOR
- B/W: WB
- Freq: CPS frequency under test
- Attenuation: 20dB
- Mon RF in: RF I/O
- Meter: RF Display

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.
Proper alignment requires a modulation analyzer or meter with a frequency response to less than
10 Hz modulating frequency. The modulation analyzer settings during this test should be set for
average deviation, a 15 kHz low-pass filter, no de-emphasis, and no high-pass filter, if these settings
are supported.
This alignment can be done with either the R-2670 Communication Analyzer or the 8901_ Series
Modulation Analyzer. The method of choice is the R-2670 analyzer.
1. Initial setup using the R-2670 Communication Analyzer:
- Connect a BNC cable between the “DEMOD OUT” port and the “VERT/SINAD DIST/DMM
COUNTER IN” port on the R-2670.
- Press the SPF key on the R-2670 to display the “SPECIAL FUNCTIONS MENU.” Move the
cursor to “High Pass,” and select 5 Hz on the soft key menu. Select 20 kHz for the “Low
Pass” setting.
- In the “RF Control” section of the R-2670, move the cursor to the “B/W” setting and select
“WIDE +/- 100 kHz” on the soft key menu.

Sec 1: 6-19

- Place the R-2670 cursor in the “Display” zone. Select “AC VOLTS” on the soft key menu.
Move the cursor to the “Range” setting and select “AUTO.”
2. Initial setup using the 8901_ Series Modulation Analyzer:
- Press the FM MEASUREMENT button. (The “Error 03-input level too low” indication is
normal until an input signal is applied.)
- Simultaneously press the Peak – and Peak + buttons. Both LEDs on the buttons should
light.
- Press the 15 kHz LP filter key.
3. Select the TX Deviation Balance alignment screen. The screen indicates the transmit
frequencies to be used. See Figure 6-26 to Figure 6-31.
4. In the "RF Control" section of the R2670, set the service monitor to the desired frequency (as
shown in the frequency list in the TX Deviation Balance alignment screen).
5. Left-click the PTT Tone: Low button.
6. Left-click the slider of the frequency selected (should be the same frequency as step 4).
7. Left-click the PTT Toggle button on the screen to make the radio transmit. The screen

Notes

Chapter 7 Encryption

This chapter provides procedures for using the encryption capability of your radio. The following
procedures are outlined:
• Loading an encryption key
• Selecting an encryption key
• Selecting an Index (only applicable to Dual Display configured radios)
• Erasing an encryption key (only applicable to Dual Display configured radios)

7.1

Load an Encryption Key
Keys will be loaded from the KVL to the radio in either clear or encrypted form depending on the
configuration of the CPS parameter "KVL – FIPS Level 3 Approved Mode". If the parameter is
disabled, keys will be sent in clear form; if the parameter is enabled, keys will be sent to the radio in
encrypted form.
NOTE: A KVL4000 or KVL3000 Plus with software version R03.52.45 or greater must be used to load
keys to a radio with "KVL – FIPS Level 3 Approved Mode" enabled.
To load an encryption key:
1. Refer to the key-variable loader (KVL) manual for equipment connections and setup.
2. Attach the KVL to the radio. The top display shows “KEYLOAD” whereas “KEYLOADING” is
shown on the front display of a Dual Display configured radio. All other radio functions, except
for power down, backlight, and volume, are locked out.
3. Refer to the KVL manual for how to load the encryption keys into the radio.
4. When the key is loaded successfully, you will hear:
• On single-key radios – a short tone.
• On multikey radios – an alternating tone.

7.2

Multikey Feature
This feature allows the radio to be equipped with multiple encryption keys. It can support two or more
encryption algorithms simultaneously (e.g., AES and DES-XL).
• Conventional Multikey – The encryption keys can be tied (strapped), on a one-per-channel
basis. In addition, the radio can have operator-selectable 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 per- talkgroup 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

Sec 1: 8-39

8.10 Ensuring Radio Submergibility
This section discusses radio submergibility concerns, tests, and disassembly and reassembly of
ASTRO APX 7000 R radios.

8.10.1 Standards
ASTRO APX 7000 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 six (6) feet of water for two hours.

8.10.2 Servicing
APX 7000 R radios shipped from the Motorola Solutions 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 water ight 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 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.

8.10.3 Water Exposure
If the radio is exposed to water, shake the radio to remove the excess water from the speaker grille
and microphone ports areas before operating; otherwise, the sound may be distorted until the water
has evaporated, or is dislodged from these areas.

8.10.4 Specialized Test Equipment
This section summarizes the specialized test equipment necessary for testing the integrity of ASTRO
APX 7000 R radios.
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.

8.10.4.1 Vacuum Pump Kit NLN9839_
The Vacuum Pump Kit includes a Vacuum Pump with gauge and a Vacuum Hose. The Vacuum
Adapter (p/n 66009259001) which connects the vacuum pump to the radio, must be ordered
separately.

8.10.4.2 Pressure Pump Kit NTN4265_
The Pressure Pump Kit includes a Pressure Pump with gauge and a Pressure Hose. As with the
Vacuum Pump Kit above, the Vacuum Adapter connects the pressure pump to the radio.

8.10.5 Disassembly
Disassemble the radio according to Section “8.7 Radio Disassembly” on page 1:8-12.

Sec 1: 8-40

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

8.10.6 Reassembly

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

To reassemble the radio:
1. Inspect the seal on the Back Chassis Assembly (E, M) for any damage or foreign material.
2. Inspect the seal on the Speaker Module (B) for any damage or foreign material.
3. Inspect the Battery Connector Seal (41) on the RF Board Assembly (G, O) for any damage.
4. Inspect the mating seal surfaces on the Main Chassis (3) for all of the above seals for
damage or foreign material that might prevent the seals from sealing properly.
Continue reassembling the radio according to Section “8.9 Radio Reassembly” on page 1:8-31.
Tighten all hardware that was loosened or removed.

8.10.7 Vacuum Test
The Vacuum Test uses a Vacuum Pump to create a negative pressure condition inside the radio. The
gauge measures this pressure and is used to monitor any pressure changes in the radio. A properly
sealed, watertight radio should have minimal change in pressure during the test.
Before starting the vacuum test:
• Remove the battery and antenna.
• Remove the Universal Connector Cover (43) or any other accessories to expose the universal
connector.
NOTE: Refer to the exploded view diagrams and parts lists found in “Chapter 10. Exploded Views
and Parts Lists” on page 1:10-1.

8.10.7.1 Vacuum Tool Setup
1. Attach one end of the hose to the Vacuum Pump. Attach the other side of the hose to the
Vacuum Adapter.
2. Tool Leak Test:
i.

Block the open end of the Vacuum Adapter.

ii.

Pull the knob on the Vacuum Pump to create vacuum.

iii.

Pump at least 15 inHg.

iv.

Watch the gauge for a minute. If there is any loss of vacuum, repair or replace the tool.

3. Ensure that the seal is attached to the Vacuum Adapter.

Vacuum Adapter

Figure 8-58. Attaching Grille Eliminator
1. Remove the Speaker Grille (27) by following steps in Section 8.7.1 on page 1:8-12 and
remove the Memory Door (33).
2. Slide the top of the Grille Eliminator under the Control Top Bezel (11) and swing it down
towards the radio. Secure the Grille Eliminator using the two center screws (29) with a torque
of 10 in lbs. See Figure 8-58.

8.10.7.3 Test Procedure
1. Attach the Vacuum Adapter onto the radio in the same manner as a radio battery. Ensure
both latches are clicked into place.
2. Place the radio on a flat surface with the Grille Eliminator facing upward.
3. Pull the knob on the Vacuum Pump to create vacuum. The vacuum test pressure should be
between 5-7 inHg.

Ensure that the vacuum pressure NEVER exceeds 7 inHg.
The radio has pressure sensitive components that can be
damaged if the pressure exceeds this limit.

Sec 1: 8-42

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

• If the needle falls more than 2 inHg, the radio fails the vacuum test and the radio might
leak if submerged. Additional troubleshooting of the radio is required.
i. Keep the Grille Eliminator and Vacuum Adapter on but remove the Vacuum Pump from
the Vacuum Adapter.
ii. Goto Section “8.10.8 Pressure Test (using NTN4265_)” on page 1:8-42.

8.10.8 Pressure Test (using NTN4265_)
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.
NOTES:When Radio is placed under the water there will be some air trapped which will be released.
This is not a failure.
Refer to the exploded view diagrams and parts lists found in “Chapter 10. Exploded Views
and Parts Lists” on page 1:10-1.
The Grille Eliminator must be used to conduct the pressure test:
If the radio is still set up from vacuum test, skip steps 1 through 4.
To conduct the pressure test:
1. Remove the Speaker Grille (27) by following the steps from Section “8.7.1 Removal of the
Speaker Grille Assemblies (A)” on page 1:8-12 and remove the Memory Door (33).
2. Slide the top of the Grille Eliminator under the Control Top Bezel (11) and swing it down
towards the radio. Secure the Grille Eliminator using the two center screws (29) with a torque
of 10 in lbs. See Figure 8-58.
3. Ensure that an seal is attached to the Vacuum Adapter.
4. Attach the Vacuum Adapter onto the radio in the same manner as a radio battery. Ensure
both the latches are clicked into place.
5. Attach one end of the hose to the Pressure Pump. Attach the other side of the hose to the
Vacuum Adapter.
6. Operate the pump until the gauge reads approximately 1 psig.

Pressure must remain between 0.5 psig and 1.5 psig.
Pressure lower then 0.5 psig may allow water into the radio,
which will damage the radio.

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

Sec 1: 8-43

8. Watch for any continuous series of bubbles. A steady stream of bubbles indicates a sign of
leakage.
NOTE: Some accumulation of air may be entrapped in the main housing which may cause a false
diagnosis of a leak. Ensure there is a steady stream of bubbles before concluding there is a
leak.
9. Note all of the seal areas that show signs of leakage. Rotate the radio to view all sides to
pinpoint the problem(s) to one (or more) of the following areas:
• Seal Interfaces
• Speaker Assembly
• Battery Connector Seal
• Main Chassis, including the Control Top
• Back Chassis
10. Remove the radio from the water container and dry the radio thoroughly. Be especially careful
to dry the area around the Memory Door (33).

To avoid equipment damage, keep the area around the
memory card opening dry to prevent water from entering the
radio.
11. With the Radio in an upright position and Control Top up, remove the vacuum adapter by
squeezing the release latches, and pulling the adapter down and away from the radio.
12. Ensure the area around the Memory Door (33) opening is dry
13. Dry the remainder of the radio and remove the Grille Eliminator.
14. See “8.10.9. Troubleshooting Leak Areas” on page 1:8-43.

8.10.9 Troubleshooting Leak Areas
Before repairing any leak, first read all of the steps within the applicable section. This will help to
eliminate unnecessary disassembly and reassembly of a radio with multiple leaks. Troubleshoot only
the faulty seal areas listed in “8.10.8. Pressure Test (using NTN4265_)” on page 1:8-42 and, when
multiple leaks exist, in the order listed.
NOTES:All disassembly and reassembly methods can be found in Section 8.7. and Section 8.9.
If in the field, water is found around the battery leads, the O-ring on the Battery should be
inspected and replaced if needed.

8.10.9.1 Seal Interfaces
• If leak occurs at one or more of the seal interfaces, disassembly of the component(s) and
inspection of the interfaces to determine if there is any damage. If no damage is observed,
re-assemble the radio as directed.
• If damage has occurred, replacement parts will be needed.

8.10.9.2 Speaker Module
• If leak occurs through the Microphone Membrane (24) or the Port Seal (25), replace these
items.
• If leak occurs elsewhere on the Speaker Module (B), the module will need to be replaced.

Sec 1: 8-44

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

8.10.9.3 Battery Contact Seal
• If leak occurs due to damage to the Battery Connector Seal (41), it will need to be replaced.

8.10.9.4 Back Chassis
• If leak occurs through the Color Display Lens (22), replace it.
• If leak occurs elsewhere on the Back Chassis (E/M), it will need to be replaced.

8.10.9.5 Control Top
• If leak occurs through the antenna or the Control Top Seal (10), replace it.
• If leak occurs elsewhere on the Control Top Assembly (J), it will need to be replaced.

8.10.9.6 Main Chassis
• If leak occurs on the Back Chassis (E/M), it will need to be replaced.

Introduction: Radio Description

Radio Description
The ASTRO APX 7000XE radios are among the most sophisticated two-way radios available. These
dual band radios are capable of operating in both VHF (136–174 MHz) and 764–870 MHz frequency
bands, UHF1 (380–470 MHz) and 764–870 MHz frequency bands, VHF (136–174 MHz) and UHF1
(380–470 MHz) frequency bands, UHF1 (380–450 MHz) and UHF2 (450–520 MHz) frequency
bands, UHF2 (450–520 MHz) and 764–870 MHz frequency bands, and, VHF (136–174 MHz) and
UHF2 (450–520 MHz) frequency bands.
The ASTRO APX 7000XE 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 APX 7000XE radios are avaiable in two configurations – Top Display and Dual Display.
Table 1-1 describes the basic features.

FLASHport®
The ASTRO APX 7000XE 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.

Chapter 2 Basic Maintenance

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

2.1

General Maintenance
In order to avoid operating outside the limits set by the FCC, we recommend that you align the
ASTRO APX 7000XE radio’s reference oscillator every time the radio is taken apart, or once per
year, whichever comes first. (See Section “6.5.1 Reference Oscillator Alignment” on page 2:6-4).
Periodic visual inspection and cleaning is also recommended.
For APX 7000XE Radios – Radio submergibility should be checked annually by qualified service
technicians.

Basic Maintenance: Handling Precautions

• The APX 7000XE radio has a vent port that allows for pressure
equalization in the radio. Never poke this vent with any objects, such as
needles, tweezers, or screwdrivers. This could create a leak path into the
radio and, the radio’s submergibility will be lost.
• The pressure equalization vent is located under the main speaker grille
near the top left side. Never obstruct or cover the small opening on the top
left with any object, including a label. Ensure that no oily substances come
in contact with this vent.
• APX 7000XE radio is designed to be submerged to a maximum depth of
six (6) feet, with a maximum submersion time of 2 hours per U.S.
MIL-STD. Exceeding either maximum limit may result in damage to the
radio. For specific U.S.
MIL-STD details, see Section “8.10 Ensuring Radio Submergibility” on
page 2:8-37.

2.2.1

APX 7000XE Radios Only
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.
If the radio has been submerged in water, shake the radio briskly so that any water that is 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
This section provides an overview of the analog mode receive and transmit theory of operation.

3.2.1

Receiving
The RF signal is received at the antenna and is routed through the Auxiliary and Multi Switch (SP3T)
ICs. The latter contains a switchable attenuator that is enabled at predetermined RF power
thresholds present at the antenna port. The output of the Multi-switch IC is applied to the first SPST
band select switch to select either VHF or 700,800 bands (see Figure 3-2), UHF1 or 700,800 bands
(see Figure 3-3), VHF or UHF1 bands (see Figure 3-4), UHF1 or UHF2 bands (see Figure 3-5),
UHF2 or 700,800 bands (see Figure 3-6) and VHF or UHF2 bands (see Figure 3-7).

3.2.1.1 GPS
The GPS architecture employs a single chip GPS receiver which decodes GPS signals at
1575.42 MHz. It is capable of producing a final position solution including full tracking and data
decode capability. The GPS receiver will operate in the autonomous mode only.
The GPS signal is tapped at the antenna port via a series resonant network which provides a very
low capacitive load to the transceiver. The signal is routed though a GPS LNA and it's output is
applied to the RF-Controller interface connector where it is eventually routed to the expansion board
for processing by the GPS IC.
The GPS receiver is setup in an autonomous one track always (OTA) mode, also known as
continuous navigation. This means the GPS will continuously track satellites for as long as the radio
is powered to ensure the best possible accuracy. In the event the radio loses visibility of the satellites
due to terrain or environmental factors such as driving through a tunnel or entering a building, the
GPS will temporarily lose its position fix. A power savings algorithm will then cycle the GPS in and
out of a sleep mode at approximately 90 second intervals until the radio has moved back into an
environment where GPS signals are present.
The user will be able to view the current latitude, longitude, and time/date stamp on the radio’s
display. The radio can also be configured to send its’ location to the system at predetermined
intervals (LRRP). Depending on system options, the user may be able to enable/disable the GPS
receiver.

3.2.1.2 VHF Front-End
From the first band select switch, a VHF signal is routed to the first pre-selector filter followed by an
LNA and a second pre-selector filter. Both filters are discrete and fixed designs and are used to band
limit the incoming energy and suppress known spurious responses such as Image and the ½ IF spur.
The output of the second pre-selector filter is applied to the RF port of the Mixer IC via a second
VHF/700,800 or VHF/UHF1 or VHF/UHF2 band select switch. The Mixer IC is also excited by a
Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz
intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF
amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).
3.2.1.3 700/800 MHz Front-End
From the first band select switch, a 700 MHz or 800 MHz band signal is routed to a second band
SPST switch which selects the 700 or the 800 band signal and routes it to the appropriate first
pre-selector filter. A third band select switch selects the output of the appropriate filter and applies it
to an LNA followed by a similar pre-selector filter/ band-select switch circuit. The signal is then routed
to second LNA whose output is applied to a discrete image filter. Both preselector filters are Surface
Acoustic Wave designs used to band limit the received energy and suppress known spurious
responses such as Image and the ½ IF spur. The output of the discrete image filter is applied to the
RF port of the Mixer IC via a second VHF/700,800 or UHF1/700,800 or UHF2/700,800 band select
switch. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert
the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed
through a crystal filter and IF amplifier which drives the input of the Abacus 3 Analog to Digital
Converter IC (AD9864).
3.2.1.4 UHF1 Front-End
From the first band select switch, a UHF1 signal is routed to the first pre-selector filter followed by an
LNA and a second pre-selector filter. Both filters are discrete and tunable designs and are used to
band limit the incoming energy and suppress known spurious responses such as Image spur. The
output of the second pre-selector filter is applied to the RF port of the Mixer IC via a second
UHF1/700,800 or UHF1/VHF or UHF1/UHF2 band select switch. The Mixer IC is also excited by a
Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz
intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF
amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).
3.2.1.5 UHF2 Front-End
From the first band select switch, a UHF1 signal is routed to the first pre-selector filter followed by a
Low Noise Amplifier (LNA) and a second pre-selector filter. Both filters are discrete and tunable
designs and are used to band limit the incoming energy and suppress known spurious responses
such as Image spur. The output of the second pre-selector filter is applied to a discrete Low Pass
Filter (LPF). The output of the LPF is applied to the RF port of the Mixer IC via a second
UHF2/700,800 or UHF1/UHF2 or VHF/UHF2 band select switch. The Mixer IC, is driven by a Local
Oscillator (LO) signal generated by the Trident synthesizer IC, at the LO port to down-convert the RF
signal to a 109.65 MHz intermediate frequency (IF). It is a passive, high linearity design with
balanced inputs at the RF and IF ports and internal LO buffer. The down converted IF signal is
passed through a 3-pole crystal filter and an IF amplifier, which drives the input of the Analog to
Digital Converter IC.

Basic Theory of Operation: Analog Mode of Operation

Sec 2: 3-7

3.2.1.6 Analog To Digital Converter
The ADC IC's front end down converts the first IF to a second IF, a 2.25 MHz signal. The second IF
is sampled at 18 MHz, a signal generated by an integrated clock synthesizer. The sampled signal is
decimated by a factor of 900 to 20 kHz and converted to SSI format at the ADC's output. The Serial
Synchronous Interface (SSI) serial data waveform is composed of a 16 bit in-phase word (I) followed
by a 16 bit Quadrature word (Q). A 20 kHz Frame Synch and a 1.2 MHz clock waveform are used to
synchronize the SSI IQ data transfer to the Digital Signal Processor IC (OMAP) for post-processing
and demodulation.

3.2.2

Transmitting
When the radio is transmitting, microphone audio is digitized and then processed by the DSP and
sent to the Trident IC (see Figure 3-9 to Figure 3-14) via the SSI interface. The Trident IC processes
the SSI data for application to the voltage controlled oscillator as a modulation signal.

3.2.2.1 VHF Transmit
Once a VHF frequency for transmit has been selected, the Trident IC and its accompanying logic
circuitry enable the correct voltage controlled oscillator which then generates the desired transmit
frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An
RF switch then routes the signal to the VHF Driver amplifier and then to the discrete final stage. The
signal is then filtered by a harmonic filter and passed through a RF switch into a directional coupler.
The Log Amp power detector monitors the output of the directional coupler and adjusts the control
voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single Pole
Double Throw (SP2T) RF switch which can route the power to the main antenna or to the Universal
Connector port of the radio.
3.2.2.2 700/800 MHz Transmit
Once a 700/800 MHz frequency for transmit has been selected, the Trident IC and its accompanying
logic circuitry enable the correct voltage controlled oscillator which then generates the desired
transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the
signal. An RF switch then routes the signal to the 700/800 MHz Driver amplifier and then to the

and adjusts the control voltages to the driver amplifier and the discrete final. Finally, the RF signal

Controller Section
The controller section (see Figure 3-15) comprises of five functional sections that are split among
three boards, which are the VOCON, EXPANSION and BLUETHOOTH OPTION boards. The main
functional section consists of a dual core ARM and DSP controller, an encryption processor (MACE),
Flash memory, and a Double Data Rate Synchronous Dynamic Random Access Memory (DDR
SDRAM). The Power and Clocks section includes a power management IC (MAKO) and various
external switching regulators, and two clock sources (12 MHz and 24.576 MHz) from which all other
controller digital clocks are derived. The Audio section has a CODEC and a class-D audio power
amplifier that provides the radio with a multiple microphone, multiple speaker design. The User
Interface section provides communication and control to the top and main Liquid Crystal Displays
(LCD) on the radio, as well as a keypad and a side connector interface conforming to Universal
Connector specifications. The Expansion Memory, GPS and Bluetooth section comprises of a Micro
SD memory interface, Global Positioning Satellite (GPS) processor, and an Option Board for radio

The ARM controller core of the OMAP processor handles the power up sequence of all devices,
including firmware upgrades, and all operating system tasks that are associated with FLASH and
SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to
store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into
SDRAM (32 MB) for execution. The ARM and DSP core jointly control and configure audio, wireless
and RF devices linked to the Serial Peripheral Interface (SPI) and Synchronous Serial Interface
(SSI) buses to enable radio FM and optional wireless communication protocols. For encryption, a
separate ARM processor is used (MACE) to encode and decode encryption packets coming in from
the main OMAP processor through the SSI interface. Its firmware is flashed via the main processor
during an upgrade request to its internal FLASH memory.

RF Test Mode
When the ASTRO APX 7000XE radio is operating in its normal environment, the radio's
microcomputer controls the RF channel selection, transmitter key-up, and receiver muting, according
to the customer codeplug configuration. However, when the unit is on the bench for testing,
alignment, or repair, it must be removed from its normal environment using a special routine, called
RF TEST MODE.
While in RF test mode:
• Each additional press of Side Button 2 advances to the next test channel. (Refer to Table 5-3.)
• Pressing Side Button 1 scrolls through and accesses the test environments shown in
Table 5-4.
NOTE: Transmit into a load when keying a radio under test.

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 after replacing (or servicing) the transceiver board.
This test can be done with either the R-2670 Communication Analyzer or the 8901_ Modulation
Analyzer.
• Initial setup using the R-2670 Communication Analyzer:
- RF Control: MONITOR
- B/W: WB
- Freq: CPS frequency under test
- Attenuation: 20dB
- Mon RF in: RF I/O

Test frequency (Ex: 851.0625 MHz)
-50.0 dBm
RF I/O

- In the Audio Zone, select the 1011 Hz PAT code and set the deviation to “PROJ25Dev:
2.83 kHz ~”.
The bit error rate screen contains the following fields:
• Rx Frequency:
This field selects the Receive Frequency directly in MHz.
• Test Pattern:
This field selects the Digital test pattern to be received by the radio. Choices are: Standard
Tone Test Pattern (Framed 1011), F2 1031 and Standard Interface Test Pattern (CCITT V.52).
• Modulation Type:
This field represents the digital modulation type of the incoming signal on which BER is to be
calculated.
• Continuous Operation:
This field allows the user the option to repeat the BER test indefinitely. A selection of Yes will
cause the radio to calculate BER on a continuous basis and update the results on this screen
after each integration time. A selection of No will cause the BER test to execute for only one
sample of the integration time and then update the display.
• Audio:
This field allows the user to select the audio output during a test. Selecting Internal will cause
the radio's built-in speaker to unmute to any signals at the desired frequency which are present
during the test. Selecting External will route the same signal to the radio's accessory connector
audio output. Selecting Mute will disable the audio output.
NOTE: There will be no audio option available for APX 7000XE when performing a Bit Error Rate
Test.
• BER Integration Time:
BER Integration Time carries with Test Pattern Type.
• Number of Frames
Number of Frames over which bit error result are accumulated to produce the result.

8.10 Ensuring Radio Submergibility
This section discusses radio submergibility concerns, tests, and disassembly and reassembly of
ASTRO APX 7000XE radios.

8.10.1 Standards
ASTRO APX 7000XE 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 six (6) feet of water for two hours.

8.10.2 Servicing
APX 7000XE radios shipped from the Motorola Solutions 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 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.

Sec 2: 8-38

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

8.10.4 Specialized Test Equipment
This section summarizes the specialized test equipment necessary for testing the integrity of ASTRO
APX 7000XE radios.
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.

8.10.5 Disassembly
Disassemble the radio according to Section “8.7 Radio Disassembly” on page 2:8-12.

8.10.6 Reassembly

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

To reassemble the radio:
1. Inspect the seal on the Back Chassis Assembly (E, M) for any damage or foreign material.
2. Inspect the seal on the Speaker Module (B) for any damage or foreign material.
3. Inspect the Battery Connector Seal (35) on the RF Board Assembly (F) for any damage.
4. Inspect the mating seal surfaces on the Main Chassis (4) for all of the above seals for
damage or foreign material that might prevent the seals from sealing properly.
Continue reassembling the radio according to Section “8.9 Radio Reassembly” on page 2:8-29.
Tighten all hardware that was loosened or removed.

8.10.7 Vacuum Test
The Vacuum Test uses a Vacuum Pump to create a negative pressure condition inside the radio. The
gauge measures this pressure and is used to monitor any pressure changes in the radio. A properly
sealed, watertight radio should have minimal change in pressure during the test.
Before starting the vacuum test:
• Remove the battery and antenna.
• Remove the Universal Connector Cover (38) or any other accessories to expose the universal
connector.
NOTE: Refer to the exploded view diagrams and parts lists found in “Chapter 10: Exploded Views
and Parts Lists” on page 2:10-1.

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

Sec 2: 8-39

8.10.7.1 Vacuum Tool Setup
1. Attach one end of the hose to the Vacuum Pump. Attach the other side of the hose to the
Vacuum Adapter.
2. Tool Leak Test:
i.

Block the open end of the Vacuum Adapter.

ii.

Pull the knob on the Vacuum Pump to create vacuum.

iii.

Pump at least 15 inHg.

iv.

Watch the gauge for a minute. If there is any loss of vacuum, repair or replace the tool.

3. Ensure that the seal is attached to the Vacuum Adapter.

8.10.7.2 Attaching Grille Eliminator

Grille Eliminator

Vacuum Adapter

Figure 8-55. Attaching Grille Eliminator
1. Remove the Speaker Grille (22) by following steps in Section 8.7.1 on page 2:8-12 and
remove the Memory Door (28).
2. Slide the top of the Grille Eliminator under the Control Top Bezel (10) and swing it down
towards the radio. Secure the Grille Eliminator using the two center screws (24) with a torque
of 10 in lbs. See Figure 8-55.

Ensure that the vacuum pressure NEVER exceeds 7 inHg.
The radio has pressure sensitive components that can be
damaged if the pressure exceeds this limit.

Sec 2: 8-40

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

4. Observe the gauge for approximately 2 minutes.
• If the needle falls less than 2 inHg, the radio passes the vacuum test.
i. Remove the Grille Eliminator
ii. Visually inspect the Port Seal Label (21) for proper adhesion to the
Speaker Module (18). Make sure there are no wrinkles or cuts to the material that would
cause a leak. Replace seal if damaged. (See appropriate section for servicing the
seals).
iii. If the seal passes this inspection, this radio is approved for submergibility. No additional
testing is required.
iv. Replace the Speaker Grille Assembly (22) and Memory Door (28) as described in the
reassembly procedures.
• If the needle falls more than 2 inHg, the radio fails the vacuum test and the radio might
leak if submerged. Additional troubleshooting of the radio is required.
i. Keep the Grille Eliminator and Vacuum Adapter on but remove the Vacuum Pump from
the Vacuum Adapter.
ii. Goto Section “8.10.8 Pressure Test (using NTN4265_)” on page 2:8-40.

8.10.8 Pressure Test (using NTN4265_)
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.
NOTES:When Radio is placed under the water there will be some air trapped which will be released.
This is not a failure.
Refer to the exploded view diagrams and parts lists found in “Chapter 10: Exploded Views
and Parts Lists” on page 2:10-1.
The Grille Eliminator must be used to conduct the pressure test:
If the radio is still set up from vacuum test, skip steps 1 through 4.
To conduct the pressure test:
1. Remove the Speaker Grille (22) by following the steps from Section “8.7.1 Removal of the
Speaker Grille Assemblies (A)” on page 2:8-12 and remove the Memory Door (28).
2. Slide the top of the Grille Eliminator under the Control Top Bezel (10) and swing it down
towards the radio. Secure the Grille Eliminator using the two center screws (24) with a torque
of 10 in lbs. See Figure 8-55.
3. Ensure that an seal is attached to the Vacuum Adapter.
4. Attach the Vacuum Adapter onto the radio in the same manner as a radio battery. Ensure
both the latches are clicked into place.
5. Attach one end of the hose to the Pressure Pump. Attach the other side of the hose to the
Vacuum Adapter.

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

Sec 2: 8-41

6. Operate the pump until the gauge reads approximately 1 psig.

Pressure must remain between 0.5 psig and 1.5 psig.
Pressure lower then 0.5 psig may allow water into the radio,
which will damage the radio.

Ensure that the pressure NEVER exceeds 1.5 psig. The radio
has pressure sensitive components that can be damaged if
the pressure exceeds this limit.
7. Maintain the pressure around 1 psig and submerge the radio into a water-filled container.
8. Watch for any continuous series of bubbles. A steady stream of bubbles indicates a sign of
leakage.
NOTE: Some accumulation of air may be entrapped in the main housing which may cause a false
diagnosis of a leak. Ensure there is a steady stream of bubbles before concluding there is a
leak.
9. Note all of the seal areas that show signs of leakage. Rotate the radio to view all sides to
pinpoint the problem(s) to one (or more) of the following areas:
• Seal Interfaces
• Speaker Assembly
• Battery Connector Seal
• Main Chassis, including the Control Top
• Back Chassis
10. Remove the radio from the water container and dry the radio thoroughly. Be especially careful
to dry the area around the Memory Door (28).

To avoid equipment damage, keep the area around the
memory card opening dry to prevent water from entering the
radio.
11. With the Radio in an upright position and Control Top up, remove the vacuum adapter by
squeezing the release latches, and pulling the adapter down and away from the radio.
12. Ensure the area around the Memory Door (28) opening is dry.
13. Dry the remainder of the radio and remove the Grille Eliminator.
14. See “8.10.9: Troubleshooting Leak Areas” on page 2:8-42.

Sec 2: 8-42

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility

8.10.9 Troubleshooting Leak Areas
Before repairing any leak, first read all of the steps within the applicable section. This will help to
eliminate unnecessary disassembly and reassembly of a radio with multiple leaks. Troubleshoot only
the faulty seal areas listed in “8.10.8: Pressure Test (using NTN4265_)” on page 2:8-40 and, when
multiple leaks exist, in the order listed.
NOTES:All disassembly and reassembly methods can be found in Section 8.7. and Section 8.9.
If in the field, water is found around the battery leads, the O-ring on the Battery should be
inspected and replaced if needed.

8.10.9.2 Speaker Module

Term

Definition

carrier squelch

Feature that responds to the presence of an RF carrier by opening or
unmuting (turning on) a receiver's audio circuit. A squelch circuit
silences the radio when no signal is being received so that the user
does not have to listen to “noise.”

central controller

A software-controlled, computer-driven device that receives and
generates data for the trunked radios assigned to it. It monitors and
directs the operations of the trunked repeaters.

channel

A group of characteristics, such as transmit/receive frequency pairs,
radio parameters, and encryption encoding.

CODEC

See coder/decoder.

coded squelch

Used on conventional channels to ensure that the receiver hears only
those communications intended for the receiver.

codeplug

Firmware that contains the unique personality for a system or device. A
codeplug is programmable and allows changes to system and unit
parameters. See also firmware.

coder/decoder

A device that encodes or decodes a signal.

control channel

In a trunking system, one of the channels that is used to provide a
continuous, two-way/data-communications path between the central
controller and all radios on the system.

conventional
