About This Manual

Scope

Format

Revision Packages

Revision Control

This manual contains general, technical and servicing informa­tion on T2000 Series II mobile two-way radios.

We have published this manual in a ring binder so that “revision
packages” containing additional information can be added as
required.

Revision packages will normally be published to coincide with
the release of information on a new PCB, and may also contain
additions or corrections pertaining to other parts of the manual.

If you return the customer registration card at the front of this
manual, you will be notified when revision packages containing
new PCB information and/or text are available. You may then
order as many packages as you require from your local Tait
Company. Revision packages are supplied ready-punched for
inclusion in your manual.

Each page in this manual has a date of issue. This is to comply
with various Quality Standards, but will also serve to identify
which pages have been updated and when. Each page and its
publication date is listed in the “List of Effective Pages”, and a
new list containing any new/revised pages and their publica­tion dates will be sent with each revision package.

PCB Information

Any portion of text that has been changed is marked by a verti­cal line (as shown at left) in the outer margin of the page. Where
the removal of an entire paragraph means there is no text left to
mark, an arrow (as shown at left) will appear in the outer mar­gin. The number beside the arrow will indicate how many para­graphs have been deleted.

The manual issue and revision status are indicated by the last
three digits of the manual product code. These digits start at 100
and will increment through 101, 102, 103, etc., as revision pack­ages are published, e.g:

3 0 1

issue status revision status

Thus, Issue 301 indicates the first revision to issue 3, and means
that one package should have been added to the manual. The
issue digit will only change if there is a major product revision,
or if the number of revision packages to be included means that
the manual becomes difficult to use, at which point a new issue
manual will be published in a new ring binder.

PCB information is provided for all current issue PCBs, as well
as all previous issue PCBs manufactured in production quanti­ties, and is grouped according to PCB. Thus, you will find the
parts list, grid reference index (if necessary), PCB layouts and
circuit diagram(s) for each individual PCB grouped together.

1.4 Product Codes

The 3 groups of digits in a T2000 product code provide information about the radio’s
model, RF type and options fitted, according to the conventions described below.

The following explanation of the T2000 product codes is not intended to suggest that
any combination of features is necessarily available in any one radio. For details regard­ing availability of specific T2000 radios, consult your nearest Tait dealer or subsidiary.

‘4’ for 175 to 225MHz
‘5’ for 400 to 470MHz
‘6’ for 450 to 520MHz
‘7’ for 330 to 360MHz
‘8’ for 800 to 870MHz transmit

851 to 870MHz receive
‘9’ for 360 to 400MHz
‘0’ for 500 to 530MHz

X-XXX ‘1’ for wide band (15kHz)

‘2’ for narrow band (7.5kHz)
‘3’ for medium band (12.5kHz)

-XXX refer to “Frequency Reference” on page 1.8.

Options

3.1 Servicing Precauti ons

3.1.1 Caution: Accidental Transmit

Under certain circumstances the microprocessor can key the transmitter. Ensure that all
instruments are protected from accidental transmit at all times.

3.1.2 Caution: Antenna Loading

The equipment has been designed to operate with a 50Ω termination impedance, but
will tolerate a wide range of antenna loading conditions. However, it is strongly recom­mended that the transmitter is not operated in the absence of a suitable load. Failure to
observe this precaution may result in damage to the transmitter power output stage.

3.1.3 Caution: Beryllium Oxide & Power Transistors

The RF power transistors in the T2000 all contain some beryllium oxide. This substance,
while perfectly harmless in its normal solid form, can become a severe health hazard
when it has been reduced to dust.

For this reason the RF power transistors should not be scratched, mutilated, filed,
machined, or physically damaged in any way that can produce dust particles.

3.1.4 Caution: CMOS Devices

This equipment contains CMOS Devices which are susceptible to damage from static
charges. Care when handling these devices is essential. For correct handling procedures
refer to manufacturers’ data books covering CMOS devices, e.g. Philips Data Handbook
Covering CMOS Devices; Motorola CMOS Data Book Section 5 (Handling Procedures),
etc.
