Chapter 1 Introduction

1.1 General

A typical ASTRO
Mobile radios known as the “bricks” to operate together with a single O7 Control Head.

The APX Dual-Radio only supports APX7500, APX6500, and APX6500Li transceivers, and it allows
users to mix and match models across tiers and power levels. For example, an APX7500 High­Power radio can operate with an APX6500 Mid-Power radio.

The APX Dual-Radio supports both High-Power and Mid-Power radios, both In-Band and Cross­Band combinations, and four different frequency bands (7/800 MHz, VHF, UHF R1 and UHF R2).

When equipped, typical features such as Scan, Secure, DTMF Hot Keypad, Volume Control, Radio
Selection, Push-To-Talk, and Monitor will be accessible through the O7 Control Head System.

Refer to Table 1-1, for detailed interactions between the two radios.

1-2 Introduction: Ordering Information

APX Dual-Radios are considered to be “In-Band” when at least one frequency band of one radio
overlaps with any one band of the other radio (single or dual band). APX Dual-Radios are considered
to be “Cross-Band” when entirely different frequency bands exist for the two radios
(single or dual band). This is based on each radio’s available frequency band(s), Primary Frequency
Band and Secondary Frequency Band, regardless of the frequencies being used in each radio’s
codeplug.

NOTE: Due to potential frequency band overlap, the combination of “UHF1” and “UHF2”, on APX

Dual-Radio is considered as “In-Band”. When the radios are “In-Band”, due to potential RF
interference, the functionality of one of the radio is limited when the other radio is transmitting.

1.1.1 APX Dual-Radio Software

The APX Dual-Radio option is supported by mobile host firmware release R12.00.00 or greater,
supports the APX Customer Programming Software (CPS) and Tuner Software.

1.2 Ordering Information

One radio must be ordered with the Primary Radio option, and the other with the Secondary Radio
option. Each radio is ordered independently and can be ordered with different options.

An audio combiner (P/N YLN4713_) can be ordered as an option on the Primary Radio, to allow
customers to combine the audio from both transceivers into one headset or speaker.

Customers can order a Stack Mount Trunnion (P/N HLN7045_) as an option in the Primary Radio to
allow them to easily mount the two radios, only when they are both Mid-Power models.

The APX Dual-Radio is incompatible with the RF Modem, DVRS MSU or PSU functionality.

The APX7500, APX6500, or APX6500Li radios can be ordered from the factory with the Dual-Radio
options. Meanwhile APX6500Li radios can be ordered with an O7 Control Head only when the
Dual-Radio software is ordered. The APX Dual-Radio option is available for APX7500, APX6500 and
APX6500 Li field upgrades, by purchasing FLASHport
(see Appendix A.4).

2.1 Overview

The APX Dual-Radio contains two APX Mobile radios, single O7 Control Head, two speakers, and
associated cabling (see Figure 2-1). The APX Dual-Radio configuration allows one control head to
control two radios. One radio is designated as the Primary Radio, while the other is designated as
the Secondary Radio.

Only one radio is accessible from the control head at any one time. The accessible radio is referred
to as the Selected Radio, while the other radio is referred to as the Unselected Radio. The O7
Control Head indicators and display always reflect the state of the Selected Radio. In general, button
presses like Push-to-Talk (PTT) only affect the Selected Radio, unless otherwise noted throughout
this document. The Unselected Radio is normally in the receive, scan, or emergency state.

Customers connect the two APX Mobile radios to each other via a short CAN cable, and connect an
O7 Control Head to one of the radios.

One speaker connects to the O7 Control Head and plays audio from the Primary Radio, and another
speaker connects to the Secondary transceiver via a speaker extension cable and plays audio from
the Secondary Radio.

2.3 O7 Control-Head Operation

The O7 Control Head (Figure 2-2) is used to control both radios. Refer to the O7 Control Head
User's Guide (68012006034) for detailed information regarding the use and operation of the APX
Mobile Radio with the O7 Control Head. All radio features which are normally accessible with a O7
Control Head, are supported in a APX Dual-Radio System unless otherwise noted in this manual.

2.3.1 Display

The display shows the status of the currently selected mobile radio. When a radio is selected, all of
its displays and indicators will be seen on the control head. When a radio is unselected, the displays
and indicators associated with it other than the transmit indicator, are not seen.

2.3.2 Basic Radio and Control Head Control

In general, button presses only affect the Selected Radio, unless otherwise noted throughout this
document, but the switch input may affect both radios.The Unselected Radio is not accessible via
the control head until the user changes the radios. The following are examples of the operation and
its effects on the respective radio:

• The Push-to-Talk (PTT) only affects the selected radio

• The ignition sense and VIP inputs affects both radios

• The HUB input only affects the selected radio, while the unselected radio always assumes HUB
is on hook

APX Mobile Dual-Radio Operation: Feature Operation 2-3

2.3.3 Backlight

Any programmable buttons that are configured for "DIM" must be configured for "DIM" on both
radios. This button press allows the radio user to change the illumination level of the radio’s
backlight.

2.3.3.1 Intelligent Lighting

Intelligent lighting is turned off on the control head when radio swap occurs, as the control head
reflects the status of the newly selected radio. Switching to the other radio will not shutdown the
intelligent lighting on the previously selected radio. Once switched back, the intelligent lighting
automatically resumes if it is still active.

2.3.4 Volume Operation

The volume on each radio is controlled independently, and can be set at different levels.

It is required to configure the MFK and Volume Up/Down feature the same on programmable buttons
on both radios, to launch two radios.

2.4 Feature Operation

The following section describes the features available for the APX Mobile Dual-Radio System O7
Control Head System.

2.4.1 APX Dual-Radio Indication

As there is only one control head, but two radios, an indication of which radio is selected and which
radio is receiving is provided at any given moment. The split screen is used to indicate the status of
both radios in system. The APX Dual-Radio icon represents the selected radio, and shows the
different states of the receiving radio. The receiving icon on the vertical banner indicates that the
unselected radio is receiving, and user needs to do Radio Swap to talk. Refer to Section 2.8, "APX

Dual-Radio User Interface," on page 2-8, for more details on the APX Dual-Radio Indications.

2.4.2 Radio Swap

Radio Swap allows user to toggle between the Primary Radio and the Secondary Radio.

As there is only one control head connected in the system, the control head only reflects the display
info of the currently selected radio. In order to select and operate the other radio, it is required to do
Radio Swap first.

• After Radio Swap, the O7 Control Head reflects the status of new selected radio.

• Radio Swap can be configured on any of the menu buttons on the O7 Control Head, any
programmable button on the O7 Control Head or keypad mic (except the DTMF keypad), or on
any DEK button.

• If the Fixed Swap Menu is enabled in CPS, the Radio Swap Menu is automatically assigned the
leftmost menu position, regardless of how a user scrolls the menu list. While both the “Fixed
Swap Menu” is enabled in CPS and the “Radio Swap” is configured in menu list, then only the
fixed swap menu shall be displayed.

• When the Radio Swap Button is long pressed, the O7 Control Head displays the selected radio
alias temporarily if radio alias is enabled in codeplug.

• If the PTT button is pressed and held, Radio Swap is not allowed.

MN000770A01-AA July 30, 2014

2-4 APX Mobile Dual-Radio Operation: Feature Operation

2.4.3 PTT Operation

When the PTT button is pressed, only the Selected Radio will key up. A Radio Swap will not be
allowed, when pressing PTT. While the radio is unselected and it receives transmit request from a
third party device, the request will be ignored.

NOTE: a) Simulcast operation, where both radios transmit simultaneously, is not supported.

b) If the APX Dual-Radio is on “In-Band” combination, and the selected radio is transmitting,
the unselected radio’s speaker is muted.
c) If the APX Dual-Radio is on “Cross-Band” combination, and the selected radio is
transmitting, customers can configure the unselected radio’s speaker to either mute or
unmute.

2.4.4 Emergency Operation

Emergency is able to launch on the selected radio, or on a pre-defined Emergency Radios (either
Primary Radio or Secondary Radio). A codeplug field is provided to configure which radio will launch
emergency, with three options as follows:

a. Selected Radio: Emergency shall launch on the currently Selected Radio, and cannot be

launched on both radios simultaneously. Thus, it is required to exit Emergency on the first
radio, in order to launch Emergency on the other radio. A long press of the emergency
button can only exit emergency, while the emergency radio is selected.

b. Primary Radio: Emergency will launch on the Primary Radio, regardless of which radio is

selected. If the Primary Radio is not selected, Radio Swap will automatically occur to
ensure it is selected. A long press of the emergency button can exit emergency,
regardless of which radio is selected.

c. Secondary Radio: Emergency will launch on the Secondary radio, regardless of which

radio is selected. If the Secondary Radio is not selected, Radio Swap will automatically
occur to ensure it is selected. A long press of the emergency button can exit emergency,
regardless of which radio is selected.

Radio Swap is allowed while the radio is in the Emergency Call Mode, but Radio Swap is inhibited
when the radio is in the Emergency Alarm, Emergency Hot Mic, or Silent Emergency State.

2.4.5 Radio Wide Features

Siren/PA, Light Bar, Gun Lock, Aux Control, DIM and Day/Night Mode are radio wide features.
Regardless of which radio is selected, customers can launch these features by pressing the related
buttons. The Radio Swap operation will not change the status of these features.

The programmable button configuration of radio wide features shall be the same on both radios.

2.4.5.1 Siren

• Siren can only connect to Primary Radio. No matter which radio is selected, Siren/PA can be
launched if Siren/PA button is pressed.

• External radio only works on Primary Radio, it can only route the Primary Radio audio to siren
speaker.

2.4.5.2 Light Bar

• Light Bar only connects to Primary Radio.

• Light bar is accessible regardless of which radio is selected.

July 30, 2014 MN000770A01-AA

APX Mobile Dual-Radio Operation: Feature Operation 2-5

2.4.5.3 Gun Lock

• Gun Lock is accessible regardless of which radio is selected.

2.4.5.4 Aux Control

• Aux Control operation can be activated by the radio user, regardless of which radio is selected.

• The Aux Control state shall not be changed after Radio Swap in Dual-Radio System.

2.4.6 Advanced Unmute Rule

For APX Dual Radio In-Band combinations, when one radio is transmitting voice, the other radio will
automatically mute but can still play tones and Voice Announcement.

For APX Dual Radio Cross-band combinations, customers are given the option of having the other
radio mute or remain unmuted. If the “Cross-Band Mute Option” field is checked in CPS, the other
radio will mute automatically when the Selected Radio transmits voice. Refer to Section 1.1,

"General," on page 1-1 for detailed interactions between the two radios in “In-Band” and “Cross-

Band” combinations.

If both radios are on the same trunking talkgroup and the “Talkgroup Mute Option” is set to “Always
Mute” in CPS, the Secondary radio will automatically mute when the Primary radio receives audio.
The Secondary Radio will still play tones and Voice Announcement. If the “Talkgroup Mute Option” is
set to “Never Mute”, both radios will play the same audio. Refer to Section 3.1.3, "Configuring

Secondary Radio Talkgroup Mute Operation," on page 3-3 for detailed Secondary Radio Talkgroup

Mute Operation.

2.4.7 Radio Inhibit

Selective Radio Inhibit allows the dispatcher to deny an individual access to the radio system by
sending a Selective Radio Inhibit Command to the radio. In an APX Dual-Radio System, both radios
need to be inhibited or uninhibited together.

• When one radio is inhibited, the other radio shall become uninhibited.

• When both radios are in an inhibited state, and one radio is uninhibited, the other radio shall
become uninhibited.

2.4.8 Over-The-Air Rekeying (OTAR)

Both radios (if equipped) are capable of supporting OTAR. The OTAR System can direct rekeys to
either radio in the Dual-Radio System, one radio at a time. User initiated rekey requests are for the
Selected Radio only. In order to rekey both radios, the user will first initiate a rekey request on the
Selected Radio. Once there is a successful rekey, the user can then change the Selected Radio
using the Radio Swap Button. The user can then initiate a rekey request for the newly Selected
Radio.

Successful OTAR rekeys on conventional channels are associated with tone and display indications.
Successful OTAR rekeys on trunking channels are associated with a tone indication.

2.4.9 Audio

If an audio recorder connects to the control head, then it can only record the transmitting and
receiving audio of the Primary Radio. It cannot record any audio from the Secondary Radio.

If the audio recorder connects to the brick TIB(J600), then it can only record the audio of this radio.

In Dual-Radio system, when tone is disabled on the Selected Radio by profile, the tone shall also be
disabled on the Unselected Radio. While tone is enabled on the Selected Radio by profile, the tone
shall also be enabled on the Unselected Radio.

While the profile is selected manually via profile configuration window, the selection applies to all the
channels which uses the last user selected profile on both radios.

A Radio Swap works as a channel change, where the profile of the newly selected radio gets
automatically refreshed. While the newly selected radio uses the last user selected profile, the tone
and light follows the setting of the last profile selected by user manually. While the newly selected
radio uses strapped profile, the tone and light gets refreshed based on the CPS setting of this profile.

2.4.11 Model Display

While powering up, the O7 Control Head displays the model of the radio, for example APX7500,
APX6500 or APX6500 Li. For APX Dual-Radio, it only displays the model of the Primary radio.

2.4.12 Data Terminal

Data terminals can connect either to the transceiver or to the control head. If connected to the control
head, the data terminal sets up a connection with the Primary Radio only.

2.5 Hot Red Receiver (HRR) Solution

The “Enable Secondary Radio Tx” CPS field on the Secondary Radio is to configure whether this
radio has transmission capability. While this field is disabled, the APX Dual-Radio system works the
same as the HRR solution of the ASTRO Spectra radio. If the “Enable Secondary Radio Tx” field is
disabled, then the Secondary Radio cannot transmit, but it can still receive group call without
registering to the trunking system. It can only support Smartnet, SmartZone and Smartzone, and
Ommilink System.

• Secondary Radio is able to receive group call and announcement group call, even if the radio
cannot transmit at all.

• Secondary Radio does not support Data and Call related features, as it doesn’t have a valid
individual ID.

• Secondary Radio does not support OTAR, it is required to load key manually.

• Secondary Radio does not support voice call monitoring on an ISSI (inter-WACN roaming) and
Intra-WACN roaming system.

• Secondary Radio does not support voice call monitoring on a Non-Motorola system.

• If the trunking system is configured to use a TDMA voice channel, customer needs to ensure
the Secondary Radio has TDMA capability and TDMA is enabled.

APX Mobile Dual-Radio Operation: Button Configuration 2-7

2.6 Button Configuration

It is recommended that the user configures all the programmable buttons the same on both radios, in
order for the APX Dual-Radio System to achieve seamless interoperability.

NOTE: User can utilize the drag and drop functionality, to drag button configuration from one radio to

the other in CPS.

Radio wide features including Siren, Light Bar, Aux Control, Gun Lock and DIM, and Emergency
feature must be configured the same on programmable buttons on both radios.

2.7 Programming

For CPS programming, a Primary Radio or a Secondary Radio can be powered independently in a
standalone configuration, or can be connected in an APX Dual-Radio System. When connected in
an APX Dual-Radio System, the radios cannot be programmed simultaneously. When one radio
enters program mode, the other radio will not be allowed to enter program mode until the Dual-Radio
System resets. Only the Primary Radio can be programmed using a data cable connected to the
control head. The Secondary Radio must be programmed with a data cable connected directly to the
Secondary Radio transceiver.

2.7.1 FLASHport® Upgrade

It is recommended to upgrade the radios without being connected to each other. When they are
connected together, the radios behaviors are as follows:

a. While upgrading the Primary Radio, there will be multiple resets and the control head will

show the Secondary Radio’s channel or zone text intermittently at the beginning.

b. While upgrading the Secondary Radio, there will be multiple resets and the control head

will show the Primary Radio’s channel or zone text intermittently at the beginning. Then
the control head will show the "Secondary Updt" string to indicate secondary updating.

Chapter 3 Codeplug Configuration

3.1 Overview

Following are the codeplug setting instructions, for configuring a mobile radio to function as part of
the APX Dual-Radio System. Using CPS, the APX Dual-Radio options can be enabled in the Radio

Configuration->Radio Wide->Dual Radio screen.

3.1.1 Enabling APX Dual-Radio as Primary or Secondary Radio

In a Dual-Radio configuration, the radio selection determines which radio is the “Primary Radio” and
the “Secondary Radio”. Radio switching between the two radios is initiated with a Radio Swap button
press or a Radio Swap menu-selection.

Figure 3-1. Enabling the APX Dual-Radio as Primary or Secondary Radio

There are three options available for the Radio Selection field:

1. Standalone Radio - Selects the current radio to operate the same as a single radio, even
though the APX Dual-Radio option is present.

2. Primary Radio - Selects the current radio to be the first radio used by the control head upon
Dual-Radio power up. This is why the Ignition Switch feature must be programmed for this
radio, which determines power on and power off for the Dual-Radio system.

NOTE: Radio Wide features such as the PA/Siren and the Universal Relay Controller are CPS-

defined for this radio codeplug only. Additionally all external hardware devices for these
features must be connected to the Primary Radio.

3. Secondary Radio - Selects the current radio to be the Second Radio used by the control
head.

3.1.2 Configuring APX Dual-Radio Emergency Operation

User selects which radio in a Dual-Radio configuration will handle the Emergency Mode Operation. It
could be either the currently selected radio or the pre-determined Primary or Secondary Radio. This
feature applies on a radio-wide basis.

This can only be accessed, when the Radio Selection field is set to Primary Radio.

NOTE: Only the Primary Radio can configure the radio that shall be used to initiate the Emergency

Operation, and the Secondary Radio shall always follow the setting of the Primary Radio.

For Emergency Evacuation Tone to be enabled in Dual-Radio configuration,
while Emergency is programmed on the Orange Button, Evacuation Tone must
be programmed as follows:
When the Emergency Radio choice is:

• “Selected Radio”, Evacuation Tone has no “Orange Button”
restrictions and can be programmed on both radios, or on either radio
as needed.

• “Primary Radio”, Evacuation Tone must be programmed on the
Primary Radio.

• “Secondary Radio”, Evacuation Tone must be programmed on the
Secondary Radio.

The Emergency Mode “Radio Swap” Rule For All Emergency Radio Selections:

When one of the radios is in Emergency Mode, and it is in the Emergency “Call” State,
a Radio Swap button-press and/or a Radio Swap menu-selection is possible.
However, Radio Swap is not possible when the radio is in the Emergency Alarm State,
and/or Radio Swap is not possible when that radio’s channel is in the “Hot Mic” or
“Emergency via Silent Audio” state mode.

The Emergency Mode “Silent Alarm” and “Unmute Option” Rule For All
Emergency Radio Selections:

When the Selected Radio is in Silent Alarm - Emergency Mode, both the Selected
Radio and the Unselected Radio follow the Unmute Option setting of the Selected
Radio.

July 30, 2014 MN000770A01-AA

Codeplug Configuration: Overview 3-3

Figure 3-2. APX Dual-Radio Emergency Mode Operation Configuration

There are three selections for the Emergency Radio as follows:

1. Selected Radio - When Emergency Mode is activated, the emergency transmission is sent on
the currently user selected radio.

NOTE: Both radios cannot enter Emergency Mode at the same time. Therefore Emergency must be

exited on one radio, before it can be initiated on the other radio. Exiting Emergency Mode is
accomplished with the normal methods.

2. Primary Radio - When Emergency Mode is activated, the emergency transmission is always
sent on the Primary Radio.

NOTE: If emergency is activated and the Primary Radio is not the currently Selected Radio, the

radios are automatically swapped making the Primary Radio the Selected Radio, and then
emergency is transmitted. Exiting Emergency Mode is accomplished with the normal
methods.

3. Secondary Radio - When Emergency Mode is activated, the emergency transmission is
always sent on the Secondary Radio.

NOTE: If emergency is activated and the Secondary Radio is not the currently selected radio, the

radios are automatically swapped making the Secondary Radio the Selected Radio, and then
emergency is transmitted. Exiting Emergency Mode is accomplished with the normal
methods.

3.1.3 Configuring Secondary Radio Talkgroup Mute Operation

User selects Dual-Radio Trunking dispatch rule that determines when the Secondary Radio mutes
and unmutes its speakers. This is only true when both radios are programmed with an identical
Trunking Talkgroup (based on the Talkgroup ID), and/or Announcement Group (based on the
Announcement Group ID), regardless of which Talkgroup(s) for these radios are operating in the
field.

This can only be accessedwhen the Radio Selection field is set to Secondary Radio.

MN000770A01-AA July 30, 2014

3-4 Codeplug Configuration: Overview

Following are the two selections for Secondary Radio Talkgroup Mute Operation:

1. Never Mute - The Secondary Radio mutes or unmutes according to normal group call
operation, where muting is never forced.

2. Always Mute - The Secondary Radio remains muted when both radios are programmed with
an identical Trunking Talkgroup (based on the Talkgroup ID), and/or Announcement Group
(based on the Announcement Group ID), regardless of which Talkgroup(s) for these radios
are operating in the field. However it can still unmute to individual calls such as Selective or
Private Calls, Call Alerts or Pages, Phone Calls, Alert Tones and Voice Announcements.

NOTE: The Secondary Radio remains muted even when the Primary Radio is not able to unmute due

to its normal unmute rules which are not being satisfied.

Figure 3-3. Secondary Radio Talkgroup Mute Operation Configuration

3.1.4 Enabling Secondary Radio Transmission

The APX Dual-Radio CPS provides the capability to enable and disable the Secondary Radio
transmission. It allows the Secondary Radio in APX Dual-Radio to transmit on the current channel,
and this feature works on a Radio Wide basis.

When the option is disabled, all transmissions from the Secondary Radio are disabled. Thus, the
radio cannot roam, register and affiliate, but it can still unmute to receive calls. See Section 3.1.3,

"Configuring Secondary Radio Talkgroup Mute Operation," on page 3-3 for Talkgroup Mute

Operation.

Codeplug Configuration: Overview 3-5

Figure 3-4. Enabling Secondary Radio Transmission

3.1.5 Configuring Cross Band Mute Operation

The Cross Band Mute Operation causes the speaker of the unselected radio in an APX Dual-Radio
configuration to remain muted to receive audio, when the currently selected radio is transmitting
voice and both radios are operating in a “cross-band” combination (operating in completely different
frequency bands). This feature works on a Radio Wide basis.

When disabled, the unselected radio is still able to unmute to receive audio, when the currently­selected radio is transmitting in a “cross-band” combination.

3.1.6 Enabling Fixed Swap Menu

Enables a “Radio Swap” menu selection to always appear in the left-most menu position of the
control head in a Dual-Radio configuration, even when the radio user scrolls through the soft-menu
buttons.

Figure 3-6. Enabling Fixed Swap Menu

3.1.7 Configuring Menu Swap

This menu selection allows user to swap back and forth between two radio bricks that are attached
to the control head in a Dual-Radio configuration. This feature applies while operating in a
Conventional or Trunking communication mode. Enabling this menu selection has no effect when
"Fixed Swap Menu" is enabled.

Chapter 4 Troubleshooting

4.1 Power-Up Errors

In the event that there is a setup problem while powering up the system, the system attempts to
notify the user of this problem by displaying power-up error messages as follows. The O7 Control
Head displays power-up errors occurring in either radio.

Any power-up failure during the self-check routine will cause the associated radio to generate a Bad
Key Tone.

4.1.1 Missing Radio

If one of the radios is not connected at power-up, an error message is displayed, and the remaining
radio continues to function. For example, when only the Primary Radio is connected, it will show
“Secondary missing”, and when only the Secondary Radio is connected, it will show “Primary
missing”.

NOTE: While only one Primary or Secondary Radio is connected, customer is not recommended to

rely on the radio, as its function shall be limited. In order to use the radio as a Standalone
Radio, it is required to change the “Radio Selection” field to “Standalone Radio”.

4.1.2 Improper Radio Combinations

If both radios go through improper radio configuration setup, “FL 01-90" is displayed to indicate a
communication error with the control head has occurred. If the error cannot be recovered, the radio
keeps resetting before it enters the maintenance mode. See Chapter 3, "Codeplug Configuration" for
details on codeplug configuration. The improper APX Dual-Radio setup can have any of the following
radio combination:

• two Primary Radios

• two Secondary Radios

• two Standalone Radios

• one Primary Radio with one Standalone Radio

• one Secondary Radio with one Standalone Radio

4.1.2.1 Secondary Radio FL 01-90 Scenarios

The first time a Secondary Radio is powered up without a Primary Radio attached, the Secondary
Radio will reconfigure itself to communicate directly with the O7 Control Head. During this process,
the control head will time out, displays a "FL 01/90" error message, and resets the radio. After the
reset, the radio will power up with full single-radio functionality, but will permanently display the
“Primary Missing” error message.

NOTE: The first time an APX Dual-Radio System is powered up, the Secondary Radio will

reconfigure itself to communicate indirectly with the O7 Control Head. During this process, the
control head will time out, displays a "FL 01/90" error message, and resets the radios. After
the reset, the Dual-Radio System will power up successfully.

MN000770A01-AA July 30, 2014

4-2 Troubleshooting: Power-Up Errors

4.1.3 Control Head ID Error

The APX Dual-Radio only allows the O7 Control Head ID to be set to #1. If the ID is not set as
required, “CH ID# ERR” shall be displayed and the radio is not able to function. User can use the
control head Front Panel Programming feature to change the control head ID.

For setting and changing the Control Head ID Reference, refer to (Section 2.2.2.5, Setting the Initial
Control Head ID) of the APX Mobiles And Control Heads Installation Manual (P/N 6878215A01).

4.1.4 Software Mismatch

Both radios shall have the same firmware version. If the firmware version does not match, the APX
Dual-Radio system shall power up with fatal error, and “SW Mismatch” is displayed along with both
radios firmware versions.

Both radios shall have the same language type. If the language type does not match, the APX
Dual-Radio system shall power up with fatal error, and “Lang Mismatch” is displayed.

4.1.5 General Radio Error

When the radio is turned on (power-up), the radio performs cursory 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. Table 4-1 aids in understanding general power-up error code
displays.

5-2 APX Dual-Radio Installation: Trunk Units

5.2 Trunk Units

This section describes trunk unit installations.

5.2.1 Radio Mounting

The APX Dual-Radio System uses CAN bus to connect two radios and the O7 Control Head
together. The Primary Radio connects directly to the Secondary Radio, and the Primary Radio
connects directly to the control head. It is recommended that the control head connect to the Primary
radio. There are two mounting styles which are “Stack Mounting” and “Side-By-Side Mounting”.

The Stack Mounting is only available for MP-MP combination, when both radios are Mid-Power
models.

For the APX Mobile Radio Mounting, refer to (Section 2.2, Radio Mounting) of the APX Mobiles And

5.2.2 Cables

This section describes the APX Dual-Radio System cables installation.

5.2.2.1 APX Dual-Radio Cables

The APX Dual-Radio Cable (P/N HKN6250_) connects the Primary and Secondary radios to the O7
Control Head via the quick-disconnect connector. Attach the yellow radio connector end of the APX
Dual-Radio Cable, to the front left of the Primary Radio (female connector, labeled “Control Unit”).
Securely tighten the two screws. Attach the red radio connector end of the cable to the front left of
the Secondary Radio (female connector, labeled “Control Unit”). Securely tighten these two screws
as well. The quick-disconnect end of the APX Dual-Radio Cable will attach to the O7 Control Head,
and is mounted in the operator’s compartment. This end of the cable also contains the connections
for the speakers, the emergency foot switch, and the ignition sense.

5.2.2.2 Power and Ground Cables

Route the red Radio Power Cables from both radios to the vehicle’s battery compartment, using
accepted industry methods and standards. It is important that both power leads are connected to the
battery, rather than using one power lead through the vehicle and splitting it to both radios. This is
because it is possible to have both mobile radios transmit at the same time (OTAR and data), and
the power cable for each radio is rated to handle the maximum transmit current of that radio only.
Both radios must connect to the same battery, to prevent cranking problem.

Be sure to grommet the firewall hole to protect the cable. Remove the 15-amp (P/N 6580283E06) or
20-amp (P/N 6580283E07) fuse from the fuseholder and connect the red lead of the Radio Power
Cable to the positive battery terminal using the hardware provided as shown in Figure 5-5. Connect

July 30, 2014 MN000770A01-AA

the black lead to a convenient solid chassis ground point. DO NOT connect the black lead directly to
the battery’s negative terminal.

The black cables must have a good ground connection if the radios are to operate properly, and to
prevent damage to the radios and cable kits. They should be grounded to the vehicle frame in the
same location. On some late-model automobiles, the ground connection between the vehicles
chassis and engine block is inadequate for good mobile radio operation. DO NOT remedy this by
connecting the radio units ground cables directly to the battery. Connect a flexible metal ground strap
between the engine block and a vehicle chassis point common to the radio set ground. Be sure the
strap is heavy enough to carry maximum transmitter supply current.

All cables should be pushed out of the way as much as possible to prevent damage.

5.2.2.3 Ignition Cable

The APX Dual-Radio Cable (HKN6250_) has an ignition sense cable that must be used with every
mobile installation. The ignition sense cable allows the radio to be turned on and off with the vehicle
ignition switch, and allows the radio to remember the state of the radio on/off switch, even if it is
changed while the vehicle is off.

• For radio ON/OFF control independent of the ignition switch, connect the orange ignition cable
to “battery hot” at the vehicle fuse block.

• For radio ON/OFF control via the ignition switch, connect the orange ignition cable to “ignition”
at the fuse block.

The ignition sense cable uses either a 3-Amp (P/N 6580283E01) or 4-Amp (P/N 6580283E02) fuse.
For other considerations when connecting the ignition cable, see the APX Mobile Radios and Control
Head Basic Service Manual (P/N 6875964M01).

5.3 Installation Considerations

Be aware of the following installation considerations:

1. Turn the vehicle’s ignition switch off during installation.

2. Connect both black leads to the same vehicle chassis point. This prevents possible ground
loop damage to the system should the ground point become bad.

3. Locate all fuses near the battery or the ignition.

5.4 Power Connections

Do the following:

1. Route the orange fused lead to the ignition voltage or battery voltage (see Section 5.2.2.3,

"Ignition Cable").

2. Route the red fused lead from each radio directly to battery positive.

3. Connect the black lead from each radio to the vehicle chassis.

5.5 APX Dual-Radio O7 Control Head Cable

Refer to Figure 5-5, the APX Dual-Radio Cable (P/N HKN6250_) cable connects the O7 Control
Head kit (P/N PMN1035_), to the dual remote radios via the quick-disconnect.

NOTE: Follow standard installation practices when routing and connecting all system cables. Use

labels to identify both ends of each cable and make sure that all connections are electrically
sound. Be sure that cables are secure and not routed or lying where they can be snagged,
cut, or crushed.

APX Dual-Radio Installation: Operator Compartment Units 5-7

5.6 Operator Compartment Units

This section describes operator compartment unit installations.

5.6.1 Quick-Disconnect Connector

NOTE: The O7 Control Head quick-disconnect connector typically mounts under the driver’s seat.

This allows the operator to disconnect it quickly and easily if so desired. Be sure adequate
clearance exists between the connector and the seat for all positions of seat adjustment.

Mount the O7 Control Head connector bracket using the #10-16 x 3/4’ self tapping screws supplied
in the Hardware kit (P/N HLN4831_). Be sure it is easily accessible. Allow for the forward and
backward movement of the seat. Use the #4-40 screws, nuts and lock washers to hold the O7
Control Head connector to the bracket.

5.6.2 Speaker Mounting

Connect both speakers to the gray, two-pin connectors at the quick-disconnect end of the APX Dual­Radio Cable (P/N HKN6250_) cable. Note the speaker wires are black/red and black/violet for the
Primary radio and are green and orange for the Secondary Radio. Be sure the plugs are fully seated,
and then tie up any surplus cable.

Two speakers are required to play the audio from each radio separately. There are two ways to
connect speaker to radio:

a. Speakers connect to radio directly.

b. One speaker connects to Secondary radio, and the other speaker connects to O7 Control

Head. The speaker connected to O7 Control Head, shall only play the audio from Primary
Radio.

Refer to Section 2.5, Speaker, of the APX Mobiles And Control Heads Installation Manual (P/N
6878215A01), for further details on speaker mounting.

5.6.3 Microphone Hang-Up Clip

Refer to Section 2.6, Microphone Hang-Up Clip, of the APX Mobiles And Control Heads Installation
Manual (P/N 6878215A01), for further details on Microphone Hang-Up Clip.

5.6.4 Emergency Footswitch

Emergency Footswitch must be connected to the control head, or wired to both radios. Refer to
Chapter 4, Options and Accessories Installation, of the APX Mobiles And Control Heads Installation
Manual (P/N 6878215A01). When installing the footswitch, discard the green and black extension
wires packaged in the footswitch kit and use instead the wiring packaged with the APX Dual-Radio
Cable (P/N HKN6250_).

5.7 Antenna Mounting

The three most important factors in antenna placement are maximizing the distance between the
four antennas, maximizing the distance between the radios and the antennas (particularly between
the VHF antenna and the radios), and using good ground planes for the antennas.

Mount the VHF antenna on the middle of the roof of the vehicle and the UHF antenna on the middle
of the trunk. The further away from the edge and towards the middle of the roof or trunk that you can
go, the better the ground plane for the respective antenna. This mounting configuration separates
each antenna and puts the VHF antenna far away from the radios. The next best placement for the
antennas is to locate them both on top of the roof. Mount the UHF antenna near the rear of the
vehicle, about 6 inches from the edge of the roof.

MN000770A01-AA July 30, 2014

5-8 APX Dual-Radio Installation: Antenna Mounting

!

C a u t i o n

As stated above, the antennas have a better ground plane the farther away from the edge of the roof.
The antennas must also be a reasonable distance from each other to minimize the interference
between them.

Avoid using lip-mounted antennas. A lip-mount does not
supply an adequate ground plane for the antennas.

July 30, 2014 MN000770A01-AA

Appendix A Other Configurations

A.1 Converting to a Single-Radio System

1. Disconnect the CAN cable between both the radios. This is to avoid one Standalone Radio
and one Primary Radio in the system, and cause FL01-90 to be displayed.

2. Read the codeplug of the radio that needs to be programmed.

3. Using CPS, change the “Radio Selection” field to “Standalone Radio”.

4. Write the codeplug into the APX Mobile radio.

5. Connect a standard O7 Control Head and cable to the newly configured APX Mobile
Single-Radio System.

A.2 Changing the Control-Head Type

• The APX Dual-Radio System is only compatible with the O7 Control Head, and all other control

head types are not supported.

A.3 Converting Radios Equipped With Dual-Radio Software into an

APX Dual-Radio System

1. Ensure both the radios are disconnected.

2. Read the codeplug of one radio.

3. Using CPS, follow the setup instructions in Chapter 3, "Codeplug Configuration" to configure
it as the Primary Radio.

4. Write the codeplug into this APX Mobile Radio.

5. The codeplug configuration is done for the second APX Mobile radio, to configure it as the
Secondary Radio.

6. Using CAN cable connect both radios, and the O7 Control Head.

A.4 Converting Radios Not Equipped With Dual-Radio Software into an

APX Dual-Radio System

• Customers who have fielded APX7500, APX6500, or APX6500Li radios are able to purchase

the Dual-Radio Software as a flashport

• This will allow them to configure their current mobiles, to be used as either Primary or

Secondary Radios in an APX Dual-Radio configuration.

• The required hardware, including the Dual-Radio Cable and Speaker Extension Cable must be

purchased separately as aftermarket kits. The optional Stack Mount Trunnion and Audio
Combiner can also be purchased separately from Motorola’s Accessories and Aftermarket
Division (AAD), if needed.

• APX mobiles using control heads different from the O7 Control Head must be retrofitted with a

remote mounted O7, in order to support the APX Dual-Radio operation.
