Safety and Servicing Information
This chapter contains general information on safety and servicing
procedures for Tait radio equipment. The procedures described in this
manual should only be carried out by service personnel trained and
accredited by Tait Electronics to service encryption-enabled TOP and
TM8000 radios.
Important Any modifications you make to this equipment which are
not authorised by Tait Electronics Ltd may invalidate your
compliance authority’s approval to operate the equipment.
Equipment Safety
ESD Precautions
Important This equipment contains devices which are susceptible to
damage from static charges. You must handle these devices
carefully and according to the procedures described in the
manufacturers’ data books.
We recommend you purchase an antistatic bench kit from a reputable
manufacturer and install and test it according to the manufacturer’s
instructions. The diagram below shows a typical antistatic bench set-up..

Screw Types
The TM8000 and TOP radios documented in this manual may have any of
the following screw types used. For full disassembly instructions, see the
relevant service information.
Torx Recess Head Screws
Torx recess head screws are the standard type of screw used in Tait
equipment, although Pozidriv and Allen recess head screws are also used in
a few special applications.
The diagram below shows a typical Torx recess head screw (actual hardware
may differ slightly from this illustration due to variations in manufacturing
techniques).
Pozidriv Recess Head Screws
Pozidriv recess head screws are used in Tait equipment in a few special
applications. It is important that you use the correct type and size
screwdriver to avoid damaging the screw head.
It is particularly important that you do not use Philips screwdrivers on
Pozidriv screw heads as the tapered driving flutes of the Philips screwdriver
do not engage correctly with the parallel-sided slots in the Pozidriv screw
head. This can result in considerable damage to the screw head if the
screwdriver tip turns inside the recess.
Note If you find you need excessive downwards pressure to keep the
screwdriver tip in the Pozidriv screw head, you are probably using
the wrong type or size screwdriver.

Components
Replacing components
Ensure that any replacement components are of the same type and
specifications as the originals. This will preventthe performance and safety
of the encrypted radios from being degraded.
Surface Mount Devices
Important Surface mount devices (SMDs) require special storage, han-
dling, removal and replacement techniques. This equip-
mentshouldbe servicedonlybyan approved Tait Dealeror
Customer Service Organisation equipped with the neces-
sary facilities. Repairs attemptedwithincorrectequipment
orbyuntrainedpersonnelmayresultinpermanentdamage.
If in doubt, contact your nearest Tait Dealer or Customer
Service Organisation.
Leaded Components
Whenever you are working on a PCB and removing or fitting components,
you must take care not to damage any copper tracks or pads. The two
satisfactory methods of removing components from plated-through hole
(PTH) PCBs are detailed below.
Desoldering Iron
Method This method requires the use of a desoldering station.
1. Place the tip over the lead and, as the solder starts to melt, move the
tip in a circular motion.
2. Start the suction and continue the movement until three or four
circles have been completed.
3. Remove the tip while continuing suction to ensure that all solder is
removed from the joint, then stop the suction.
4. Before pulling the lead out, ensure it is not stuck to the plating.
5. If the lead is still not free, resolder the joint and try again.
Note The desoldering iron does not usually have enough heat to desol-
der leads from the ground plane. Additional heat may be applied
by holding a soldering iron on the tip of the desoldering iron (this
may require some additional help).
Component Cutting
Method 1. Cut the leads on the component side of the PCB.
2. Heat the solder joint sufficiently to allow easy removal of the lead
by drawing it out from the component side: do not use undue force.
3. Fill the hole with solder and then clear with solderwick.

Midian Encryption Programming and Service Manual Safety and Servicing Information 11
June 2006 © Tait Electronics Limited
Cased Mica Capacitors
Cased mica capacitors can be removed by heating the top with a heavy-duty
soldering iron and gently lifting the capacitor off the PCB with a
solder-resistant spike or equivalent. Make sure that the solder at the tab
solder joint is melted or removed before attempting to lift the capacitor.
Encryption Modules
Important The encryption module can control the radio PTT, and
while programming, may cause the radio to transmit.
Always provide protection for test equipment (such as RF
signalgenerators) so they cannotbedamagedby transmitter
power.
Important Each encryption module is provided with a sheet for
recording programmable settings. As Midan TVS-2
encryption codes, and all VPU12 module settings cannot
be read back, it is strongly recommended that all settings be
recorded for each fitted module and kept in a secure place.

1 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.
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.
However, even when encryption is not selected, an encryption-enabled
radio will always decode encrypted communication from any radio with
compatible modules and settings.
Note When modules or settings are incompatible, communication is
reduced to unintelligible noise.

must not be removed when fitting a module into a TM8000
radio, as these snap-offs include screw holes necessary to fit
the module. The snap-offs are removed for TOP applica-
tions.
2.2 Radio Hardware Compatibility
TOP Radios
The TOP Encryption Upgrade Flex PCB described in this manual is
suitableforuseinmostTOP5000radios(5010,5020,5035,5040).The flex
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.
TM8000 Radios
At the time of printing, the TM8000 Encryption Options PCB described
in this manual is compatible with any TM8000 radio. However, the

dealer.

18 Midian Encryption Midian Encryption Programming and Service Manual
June 2006 © Tait Electronics Limited
2.3 Radio Firmware and Software Compatibility
TOP Radios
Encrypted TOP radios require specific encryption-capable radio firmware
and programming software. This is fitted during manufacture ofencryptable
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.
TM8000 Radios
EncryptedTM8000radiosrequire a firmwarechange to support encryption
function. This is normally fitted during manufacture. Standard TM8000
programming software supports encryption functions in TM8100
applications. A custom version of programming software is required for
TM8200 applications. Some specific I/O settings are required to support
encryption in all TM8000 radios. For more information, see
“Programming the TM8000 radio” on page 52 of this manual.
2.4 Encryption Module Programming
Important When programming a Midian module, it is strongly rec-
ommended that you use the manufacturer’s default secu-
rity codes. See the Midian programming manual for more
information on standard codes, and instructions for chang-
ing them if necessary.
■TOP and TM8000 radios fitted with Midian TVS2-Tait Encryption
Modules can be programmed without opening the radio, using 219-
02931-0X Direct Programming Cable (TOP) or 219-03026-0X
(TM8000). Instructions forTVS2-Tait Module Direct Programming are
on page 19.
■TOP and TM8000 radios fitted with Midian VPU-12 modules are
factory-programmed with the correct settings, and Tait recommend that
these be used. However, encryption codes can be changed, using the
Midian-supplied clip-lead cables fitted directly to the module. See the
KL3 Programmer documentation for instructions.
Specific information on module parameter settings and values is available in
the Programmer and Module service manuals. However, some useful
module settings information is included in this manual on page 20.
Note Somelinksettingsand functionsonthemodulesmay be forfuture
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 Direct Programming
A radio with Midian TVS2-Tait Encryption Module can be direct-
programmed without openingthe radio, to change anyof its programmable
parameters. This requires a dedicated direct programming cable as follows:
■TOP radios use 219-02931-0X (see Cable Specifications on page 25)
■TM8000 radios use 219-03026-0X (see Cable Specifications on page 25)
Note The Midian KL3 programmer includes a dedicated programming
cable. However, as this cable requires the radios to be opened, its
use is not recommended or supported by Tait.

TOP radio usually requires a hard-wired connection from the Midian
programmer tothe module. Thisrequiresopeningthe radioand connecting
the dedicated programming cable (provided with the Midian programmer)
to pads on the Tait flex or board.
Important Each encryption module is provided with a sheet for
recording programmable settings. As Midan VPU12 mod-
ule settings and TVS-2 encryption codes cannot be read
back, it is strongly recommended that all settingsberecorded
for each fitted module and kept in a secure place.
2.5 Encryption Module Settings
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.
