For other encryption modules, check with a Tait Service Centre, or www.taitworld.com/.

Modules listed can be fitted to either TOP or T2000 radios, with the exception of the Midian

TVS-2 modules (see above). However, the modules will require some customisation to suit the

radio type. Details are included in the module manufacturer’s documentation, but differences

include:

removal of snap-off sections to fit a module into a TOP radio. Note that these snap-offs

include screw holes necessary to fit the module into a T2000 radio, so should not be

removed for T2000 application.

some modules require module-specific link settings on the Encryption Upgrade Flex PCB,

depending upon the radio type and the system configuration. These settings are described

in the module manufacturer’s documentation.

2.4 Radio Hardware Compatibility

Tait Orca Portable Radios

The TOP Encryption Upgrade Flex PCBs described in this manual are suitable for use in most

TOP 5000 radios (5010, 5020, 5035, 5040). The flexes can be retrofitted to most radio models,

but this should first be verified by providing the serial numbers to a Tait Service Centre for

confirmation.

T2000 Radios

The T2000 Encryption Upgrade Flex PCBs described in this manual are suitable for radios which

contain the Enhanced HC11 Control PCB (IPN 220-01344-XX). This can be verified by

providing the serial numbers to a Tait Service Centre for confirmation.

2.5 Radio Firmware and Software Compatibility

Tait Orca Portable Radios

Encrypted TOP radios require specific encryption-capable radio firmware. This is fitted during

manufacture of encryptable radios, but will need to be programmed separately where an

encyption upgrade kit is used. Contact the Tait Strategic Sales Team for confirmation of

encryption firmware support.

T2000 Radios

Encryption-capable T2000 radios require no firmware change to support encryption function.

Encrypted Radio Programming and Service Manual Copyright TEL

M2259-00-200-812 System Operation 13

3 System Operation

Encrypted radios provide increased privacy for conversations by jumbling speech so that only

radios with the right hardware and settings can reconstruct it. The diagram below shows a typical

radio system comprising portable radios, mobile radios, base stations or repeaters and an OTAR

(Over-the-Air Reprogramming) programming station.

Whether or not a radio transmission is encrypted is the user’s choice. When the encryption mode

is selected, the radio sends and receives encrypted calls to and from other radios with compatible

encryption module and settings (keys or codes). However, even when encryption is not selected,

an encryption-enabled radio will always decode encrypted communication from any radio with

compatible modules and settings.

When modules or settings are incompatible, communication is reduced to unintelligible noise.

3.1 Configuration

Both encryption modules and radios have many settings which affect encryption. You will need

to refer to the installation and programming manuals provided with all your encryption hardware.

This manual describes how to connect your hardware for setup, testing and maintenance, but

does not describe how to determine the settings you should use. These should be determined

during system design by technical personnel trained in the relevant Tait and third-party products.

Contact your Authorised Tait Service Centre for further assistance.

3.2 Compatibility

Some combinations of encryption hardware, software, radio versions and configurations,

accessories and programmable features may not be supported. In particular:

14 System Operation M2259-00-200-812

Encrypted Radio Programming and Service Manual Copyright TEL

Encryption modules from different manufacturers are not compatible

Features available in a Tait Encryption-enabled radio are not necessarily the full list of

features specified by the module manufacturer.

The system designer should confirm that the system meets user requirements.

3.3 Tait Encryption Interface Signal Specifications

For TOP Encryption Interface Signals, see page 15. For T2000 Encryption interface signals, see

page 48.

M2259-00-200-812 Tait Orca Portable (TOP) Encryption 15

4 Tait Orca Portable (TOP) Encryption

Tait Orca Portable (TOP) radios can be encryption-enabled at a Tait Authorised Service Centre

using the TOP Encryption Upgrade Kit (IPN TOPA-EA-001) and a supported Transcrypt or

Midian Encryption Module. This kit comprises a flex circuit which brings all the required

connections for encryption to a single connector for plug-in encryption functionality. Full fitting

instructions for the flex are included in this manual.

Note: Module component values change between TOP and T2000 radios. Ensure the module

fitted has been configured for the TOP radio. See the encryption manufacturer’s service

manual for more information.

User Interface

This is a hardware and firmware solution. It offers:

user control of Encryption state (On or Off) by any Function button, programmed by the

user, with either short or long press activation

menu access to Encryption state (where menu function is available)

Where the radio has both a display and a keypad, it also provides:

encryption state by text on the radio display

user control of up to 16 encryption codes by keypad

continuous display of the currently selected encryption code

programmable control of the number of user accessible codes

display of the ‘accessory triangle’ indicating when transmitting or receiving encrypted

signals (Transcrypt modules) or if the encryption state is ON (Midian modules).

4.1 Circuit Operation

Functions of the interface are:

Transmit and receive audio is intercepted by the flex, where C572 and C567 are removed.

Audio passes through the encryption module and is encrypted or not according to the

encrypt state.

Links (not shown on the block diagrams, see the circuit diagram on page 21) allow the radio

to function as a standard, unencrypted radio when an encryption flex is fitted with no

module. To enable the radio to operate when a module is not fitted (-06 flex version only),

solder-short Link-6 and Link-7 to loop the audio back to the normal radio path. Radios with

-07 (or later version) flexes fitted do not require these links fitted.

The existing flex circuit that connects the Main PCB to the User Interface PCB is discarded,

and is replaced by the encryption flex circuit.The low voltage reset from the radio is used

to reset the module circuit.

The diagram that follows shows the encryption circuit operation for both a TOP encrypted radio

and a TOP radio as a programming radio.

Note: When using a TOP radio as an OTAR programming radio, ensure encryption mode is

turned off.

An addressable latch on the radio UI board is replicated on the encryption flex and driven by the

same serial data bus. The radio micro uses four outputs of this latch to control the encryption

code select bus. Two other outputs provide the PTT and Mode drives to the module. The

remaining two pins function as normal for the UI board and are unused on the flex.

The external PTT and internal PTT are combined within the radio software to provide the PTT for

the module.

The radio LED is under normal micro control, and provides no indication of encryption status.

The module IND (status) output is fed to the SENSE-1 input to the radio micro. This allows the

software to display the status on the LCD accessory annunciator.

Encryption code control is achieved by keypad entry. Encryption Mode can be assigned to a

function key when the radio is programmed or through a menu. (On most radios, this function is

user-programmable.) This can be a long or short press of any valid function key, usually a long

press of Function-2 key.

Transcrypt Module Programming

Note: All Transcrypt modules can be programmed directly, via a dedicated programming

cable, or over the air (OTAR)

This procedure requires:

a computer with OTAR programming software

a Transcrypt Programmer

a TOP or T2000 Lead (part of the TOPA-EA-002 Encrypted Radio Programming and

Service Kit) for OTAR programming

a direct programming cable (TOPA-EA-008G) for direct programming

a TOP or T2000 radio to use as a programming radio (OTAR only)

Transcrypt modules fitted to a TOP radio can be programmed using Over-The-Air-

Reprogramming (OTAR). The OTAR programmer allows a computer to alter a radio's encryption

module settings remotely, within the coverage range of the radio system.

M2259-00-200-812 Tait Orca Portable (TOP) Encryption 19

For direct programming, the module is programmed directly, using a TOPA-EA-008G cable

connected to the radio’s accessory connector.

Note: Any TOP radio can be used for OTAR programming. However, if an encryption

module is fitted, it is important that the encryption function is turned off when

programming.

Note: If a T2000 radio is used for OTAR programming, a T2000 Encryption Flex must be

fitted to the radio. A module is not required, however, if one is fitted, it is important

that the encryption function is turned off when programming.

Refer to the following publications for detailed programming instructions

Transcrypt OTAR Programmer Manual

Transcrypt Module Manual

Transcrypt Programming section (page 69) of this manual

4.2.1 Midian Module Programming

The Midian VPU-12 module is preprogrammed by the manufacturer and does not normally

require programming. Its programmable functions can be programmed by open-radio direct

programming. It does not support OTAR programming. The Midian TVS2 module supports

OTAR programming of encryption codes only. However, the TVS2 supports direct programming

of all programmable functions.

Refer to the following manuals for detailed programming instructions

Midian Programming instructions

Midian Module Manual

Midian Programming section (page 79) of this manual

Important Additional Information

Once encryption is enabled, set the function buttons to:

 turn encryption ON and OFF

 access Code Change mode (optional)

 set the number of user-accessible codes (optional)

Economy mode is the factory default, but is not recommended with

encryption-enabled radios as it will cause loss of sync pulses. This may result

in failure to decode some encrypted calls after a period of inactivity.

If the flex version is -06 (or earlier), to enable the radio to operate as a

standard, unencrypted radio when a module is not fitted, solder-short links

Link-6 and Link-7 on the flex. This modification will loop the audio back to

the normal radio path. See the PCB layout section on page 21 of this manual

to locate the links.

If radios have no display, ensure no other function (eg incoming selcall or

repeater talkaround) is programmed to utilise the orange LED, or it will be too

difficult to determine encryption status.

4.3 Programming the Encryption Module

Note: When using a TOP radio as a programming transmitter, if an encryption module is

fitted, ensure the encryption function is turned off.

20 Tait Orca Portable (TOP) Encryption M2259-00-200-812

Encrypted Radio Programming and Service Manual Copyright TEL

Equipment setup and programming instructions are described in the Transcrypt Programming

section on page 69 or the Midian Programming section on page 79, depending upon the origin of

the encryption module. Refer also to programming and service manuals with your Transcrypt or

Midian encryption module and programmer.

Service Desk OTAR programming may be unsuccessful if:

the target radio is open during programming

the programming radio and the target radio are oriented differently eg one laying down, one

upright

one radio is set to High Power

4.4 Testing the Encryption Module

Equipment setup and testing instructions are described in the Transcrypt Programming section on

page 69 or the Midian Programming section on page 79, depending upon the origin of the

encryption module.

With encryption off:

Check normal power-up of the radio, with the normal display messages and confirmation

tones.

Check that receive and transmit audio are functioning, using a service instrument or another

radio on the same channel.

With encryption on:

Check that receive and transmit audio are functioning, using another T2000 or TOP radio

with the same encryption module, programmed with the same codes, on the same channel.

Where a code hopping module is fitted, confirm encryption is active by listening for the

initial sync burst on the receiving radio

Where a code inversion module is fitted, confirm encryption is active by pressing any

function key - the confidence tone will be a higher frequency than normal.

Check the Encryption User Interface features – status indicators, encryption settings etc.

(See the TOP Encryption User’s Guide information provided on page 37).

4.7 TOP Fault Finding

Diagnosis TIP

If unsure whether a radio with simple inversion encryption is in encrypt or clear mode: while in

standby (without any incoming signal), hit a keypad or function key to produce an audible beep. If

the radio is in encrypt mode, the beep will be a much higher frequency than normal.

Symptom Cause Action

Radio transmits regularly -

goes into emergency mode

Audio not operating

Radio stopped working after

it was dropped.

Module not squarely in connector

Re-plug connector to

module (radio will need

to be opened)

Receives okay, but no

transmit audio. Module may not be receiving PTT Check PTT links.

External mic PTT does not

operate. Incorrect links on flex Check PTT links.

Encryption on/off button only

changes encryption state

every second press

Module may be programmed for level-

sensitive instead of edge-sensitive.

Reprogram encryption

Module does not decrypt

audio.

Module may have been programmed

differently to the rest of the fleet.

Reprogram with correct

settings.

Module acknowledges its ID,

but not accept any other

commands.(Transcrypt

Module may be programmed with the

wrong programmer, with a different

Master code.

Reprogram with correct

programmer - will need

a ‘Force Download’

(Refer to Transcrypt

Manual)

Module acknowledges its ID,

but not accept any other

commands. Force download

does not fix. (Transcrypt

module only)

Module may be damaged or have failed. Replace with a new

module.

Radio will not power up

properly, shows database

error, continuous Red LED.

Radio has been downloaded with

incorrect firmware and/or programmed

with incompatible software.

Contact Customer

support.

Radio will not power up

properly, display blank.

Flex-edge connectors may not be

correctly plugged.

Module faulty.

Replug connectors

checking flex is square

to connector.

Replace module.

Poor audio quality Module has links set for wrong radio type. Set links according to

manuals.

Radio set to one code can

hear another radio no matter

what code it is set to.

Module may have same code strings set

in all code registers.

IC1 on flex may not be working, or not

getting address information from micro.

Reprogram module with

different codes.

Replug loom

connectors, check

circuit.

Audio sounds very muffled

(Midian modules only)

Inversion module may have very low

inversion frequency.

Program module to a

higher frequency.

Audio sounds very “thin”.

(Midian modules only) Inversion module may have very high

inversion frequency.

Program module to a

lower frequency.

4.8 Fitting the TOP Encryption Upgrade Flex

Note: Extreme care is critical when disassembling the radio, as failure to disassemble it

correctly may damage the seal and shield resulting in permanent damage. Disassemble

according to standard procedures, using the recommended tools. (See page 7).

Prepare Flex

1. Locate R9 and

remove

2. Locate R7 and fit

0Ohm chip (if not

already fitted)

Note: When fitting a

TVS-2 module

to an -07

version flex,

remove

components

R5 and R6.

Symptom Cause Action

Audio sounds squeaky or

croaky. (Midian modules

only)

Transmit and receive inversion

frequencies may be different.

Ensure both radios are

using same frequency. If

problem still exists,

reprogram module

Receiving radio occasionally

or frequently fails to decode

sync pulse. Audio is

unintelligible for several

seconds then comes right.

(Transcrypt modules only)

System delay may be set too short

Radio may have economy mode enabled

Reprogram module, or

consider if CTCSS can

be removed from some

parts of radio system.

Reprogram radio to

disable economy mode

Radio confidence and alert

tones are different, rapidly

varying tones.

This is normal when either the

transmitting or receiving radio creates an

alert tone or confidence tone during an

encrypted conversation.

No action - not a fault

Radio makes unusual,

distorted beeps at turn on.

Radio confidence tones may be set to

high. (Not all radios exhibit this)

Reprogram radio to set

confidence tones to low.

Module OTAR programming

does not work. (Transcrypt

modules only)

Module may have been corrupted or

damaged by high levels of radiated RF, eg

a portable on high power while the radio

has covers removed

Reprogram module.

Encryption indicator triangle

turns on and off randomly.

Both LK-3 links on TOP flex may be

connected, not just one.

Remove one LK-3 link.

(IPN T2000-EA-001) and the appropriate Transcrypt or Midian Encryption Module.

This kit comprises a flex circuit which brings all connections required for encryption to a single

connector for plug-in encryption functionality. This is the Tait standard encryption interface.

Instructions for fitting the flex are on page 65 of this manual.

Note: Ensure the encryption module to be fitted has been configured for the T2000 radio. See

the module manufacturer’s service manual for more information.

This is a hardware-only addition to the radio. It offers:

user control of Encryption state – On or Off – by the Aux key (or a Function key

programmed as Aux)

encryption state indicated by lighting the Green LED on the Aux (or a Function) key.

5.1 Circuit Operation

The diagram below shows the encryption circuit operation for both a T2000 encrypted radio and

a T2000 radio as a programming radio.

Note: When using a T2000 radio as a programming radio, an encryption module should not

be fitted.

Connecting an encryption module automatically diverts the audio through the module. No link

setting changes are required if a module is removed.

Transmit and receive audio is intercepted by the flex from the Scrambler/Vox connector, across

R673 and R638. Audio passes through the encryption module and is encrypted or not, according

to the user-selected encrypt state.

The module Mode input is driven from the Aux signal from the radio micro. When the radio is

48 T2000 Radio Encryption M2259-00-200-812

Encrypted Radio Programming and Service Manual Copyright TEL

programmed, this button function is set to Aux, Latching.

The low voltage reset from the radio is used to reset the module circuit.

Signal levels and pin assignments

5.2 Programming the T2000 radio

Standard radio programming software is used.

Ensure the Accessory function key is enabled and configured to latching. For T2000 versions

with no accessory key, set a function (Fn) key for this function.

5.3 Programming the Encryption Module

Note: To set up a T2000 radio as an OTAR programming radio, it should have a flex fitted,

but no encryption module.

Equipment setup and programming instructions are described in the Transcrypt Programming

section on page 69 or the Midian Programming section on page 79, depending upon the origin of

the encryption module.

Refer also to programming and service manuals with your Transcrypt or Midian encryption

module and programmer.

Service Desk OTAR programming may be unsuccessful if:

the target radio is open during programming

the programming radio and the target radio are oriented differently eg one laying down, one

5.4 Testing the Encryption Module

Equipment setup and testing instructions are described in the Transcrypt Programming section on

page 69 or the Midian Programming section on page 79, depending upon the origin of the

encryption module.

With encryption off:

Check normal power-up of the radio, with the normal display messages and confirmation

tones.

Check that receive and transmit audio are functioning, using a service instrument or another

radio on the same channel.

With encryption on:

Check that receive and transmit audio are functioning, using another T2000 or TOP radio

with the same encryption module, programmed with the same codes, on the same channel.

Where a code hopping module is fitted, confirm encryption is active by listening for the

initial sync burst on the receiving radio

Where a code inversion module is fitted, confirm encryption is active by pressing any

function key - the confidence tone will be a higher frequency than normal.

Check the Encryption User Interface features – status indicators, encryption settings etc.

6 Transcrypt Programming

Transcrypt encryption modules can be programmed via Over-The-Air-Reprogramming (OTAR)

or Direct Programming (TOP radios only).

6.1 OTAR Programming

The Transcrypt OTAR Programmer allows a computer to alter a radio’s encryption module

settings remotely, anywhere within the coverage range of the radio system.

The two applications for this are:

at a service desk during initial setup, test or maintenance of a radio.

while on normal operation in a fleet, to change the settings of modules in fleet radios for

security or operational reasons.

Service desk OTAR programming may be unsuccessful if:

the target radio is open during programming

the programming radio and the target radio are oriented differently eg one laying down, one

upright

one radio is set to High Power

Refer to the OTAR Programmer and Module manuals for features which are programmable, what

values they can have and how to set them.

Note: Some link settings and functions on the modules may be for future use, or require

special set-up or additional components to operate. If a function is not documented,

please ask for assistance before using it.

6.2 Direct Programming

Via direct programming, the Transcrypt Programmer allows a computer to alter a radio’s

encryption module settings by direct connection via the TOP Encryption Direct Programming

Cable (IPN TOPA-EA-008G) as shown in the diagram below. This is used at a service desk

during initial setup of the radio, testing or maintenance, or to change the way features are

programmed.

Refer to the Transcrypt Programmer and Module manuals for features which are programmable,

what values they can have and how to set them.

Note: Some link settings and functions on the modules may be for future use, or require

special set-up or additional components to operate. If a function is not documented, ask

for assistance before using it.

6.3 Operation

The following sequence of events occurs during Over-The-Air-Reprogramming and Direct

Programming:

1. Codes are typed, or menus selected on the program running on the PC

2. The RS232 cable carries data to the Programming modem.

3. The modem encodes this data to a sequence of audio tones using PSK signalling

4. The OTAR lead applies these audio tones to the programming radio audio input, and

transmits them over the radio channel.

5. All radios on the channel receive the programming signal.

6. As audio passes through the encryption modules, they check the ANI ID.

7. Radios not matching the ANI ID ignore the data

8. The single radio with the matching ID accepts the data, and updates its memory registers.

9. It then transmits back an acknowledge message indicating successful data loading.

10. The programming radio passes this message back to the modem which converts it to an

‘acknowledge response’ message displayed on the computer.

6.4 Using a TOP as an OTAR Programming Transmitter

A standard TOP radio - with no Encryption module fitted - on the correct frequency is all that is

required for an OTAR programming transmitter radio. The TOP programming cable (IPN 219-

Accessory connector that has all signals required as standard.

For more information, see the TOP Programming Cable Specifications on page 74.

Note: Ensure the accessory connector is firmly latched, otherwise it may not make

connection to all the required signals.

6.5 Using a T2000 as an OTAR Programming Transmitter

The T2000 programming cable (IPN 219-02835-0X) connects the OTAR Programmer to the

T2000 programming transmitter radio through the 9 Way D Range socket fitted to the radio rear.

For more information, see the OTAR Programming Cable Specifications on page 74.

6.6 Programming a Transcrypt Encryption Module

Refer to the OTAR programmer manual for software commands and register values.

Each encryption module is provided with a sheet for recording programmable settings. As the

module settings cannot be read back, it is strongly recommended that all settings be recorded for

each radio and kept in a secure place.

It is important to understand the meaning of the various identifiers in the programmer’s manual.

A typical sequence for programming is:

1. Briefly transmit in secure mode from the radio to be programmed, and note the module id

‘SXnnnn’ which appears on the computer terminal screen.

2. Check the radio acknowledges an Annn call, by returning the message confirmation AK

nnnn xx on the PCB.

3. Enter programming commands as in programmer manual, for such things as system delay.

4. The radio confirms a successful operation by returning the message confirmation AK

nnnn xx.

Note: After a Move Download command (see TR30-3061 Manual), turn the radio off then on,

so that the module recognises the new scramble code.

6.7 Security Codes

Security Codes

Note: When programming a Transcrypt module, you may wish to change the default

Transcrypt security codes. See the Transcrypt programming manual for more

information on standard codes, and instructions for changing them if necessary.

Transcrypt assigns each customer a unique master code, and programs modules with this during

manufacture. The security of an encryption module is provided by the total code. This is a very

large number, resulting in too many different codes for an eavesdropper to find any code by trial.

This total code is a combination of the master code in the programmer used to program the

module, and the scramble code in the module. The master code acts as a customer code,

preventing accidental use of a scramble code in one fleet, which would allow decrypting of

Transcrypt Identifier Description

Unit ID ANI for individual module addressing

Group number ANI Group number for paging or alerting a group of radios

Electronic Serial Number (ESN) = Main

number

Serial number for controlling access to parameter changes

Scramble Code Unique multi-digit code sets which codes module can

decipher.

72 Transcrypt Programming M2259-00-200-812

another fleet’s messages.

Normal programming of a module does not change the master code, just the scramble codes, and

other settings. Force downloading should not normally be necessary – only use if you know you

have the correct master code in your programmer.

Note: Service shops installing modules for specific customers must ensure they specify the

end-customer when ordering from the supplier.

7 Midian Programming

To program Midian Encryption Modules fitted to either a T2000 or a TOP radio usually requires

a hard-wired connection from the Midian programmer to the module. This requires opening the

radio and connecting the dedicated programming cable (provided with the Midian programmer)

to pads on the Tait flex circuit.

Note: TOP radios fitted with Midian TVS2-Tait Encryption Modules and using -07 version

encryption flex (or later) can be programmed without opening the radio, using TOPA-

EA-007G Direct Programming Cable. Instructions for TOP TVS2-Tait Module Direct

Programming are on page 81.

Refer to the Programmer and Module service manuals for specific information on module

parameter settings and values.

Note: Some link settings and functions on the modules may be for future use, or require

special setup or additional components to operate. If a function is not documented,

please ask for assistance before using it.

TVS2-Tait Over-the-Air Programming (TOP and T2000 radios)

The Midian TVS2-Tait Encryption Module can be remotely programmed to change encryption

code. Contact your Tait Service Centre for more information.

TVS2-Tait Direct Programming (TOP radios only)

A TOP radio with Midian TVS2-Tait Encryption Module and using -07 version encryption flex

(or later) can be direct programmed without opening the radio, to change any of its

programmable parameters. To utilise this feature, you require a dedicated direct programming

cable TOPA-EA-007G (see page 86 for more information).

Note: This cable is not part of the Encryption Programming and Service Kit and must be

ordered separately from your Tait Dealer.

7.1 Circuit Operation

The programming software on the PC sends data down the standard serial cable to the

programmer, which is hardwired to the module microcontroller via pads on the TOP or T2000

Encryption Upgrade Flex.

7.2 Programming a Midian Encryption Module (Hardwired)

Note: See page 81 for information on direct programming a TOP radio with TVS2-Tait and -

07 version (or later) flex using TOPA-EA-007G Direct Programming Cable.

To connect the Midian programming cable according to the diagram below, first solder a short

length of wire to the indicated pads, then attach the cable clip to it.

Programming information

Refer to the programmer manual for PC settings, software commands and register values.

Before programming the Midian encryption module, it is important to understand the meaning of

various identifiers in the programmer manual. Some of these are outlined in the table below:

Note: Each encryption module is provided with a sheet for recording programmable settings.

As some module settings cannot be read back, it is strongly recommended that all

settings be recorded for each radio and kept in a secure place.

Security Codes

When programming a Midian module, it is strongly recommended that you use the

manufacturer’s default security codes. See the Midian programming manual for more

information on standard codes, and instructions for changing them if necessary.

7.6 Testing the Midian Encryption Module

With encryption off:

Check normal power-up of the radio, with the normal display messages and confirmation

tones.

Check that receive and transmit audio are functioning, using a service instrument or another

radio on the same channel.

With encryption on:

Check that receive and transmit audio are functioning, using another T2000 or TOP radio

with the same encryption module, programmed with the same codes, on the same channel.

Confirm encryption is active (where a hopping code module is fitted) by listening for the

initial sync burst on the receiving radio

Confirm encryption is active (where an inversion code module is fitted) by pressing any

function key - the confidence tone will be a higher frequency than normal.

Check the Encryption User Interface features – status indicators, encryption settings etc.
