About This Manual
Scope This manual contains general, technical and servicing informa-
tion on T800 Series II ancillary equipment.
Format We have published this manual in a ring binder so that "revision
packages" containing additional information pertaining to new
issues of PCBs, or to additional ancillary equipment, can be
added as required.
Revision Packages Revision packages will normally be published when an ancillary
equipment manual requires overhaul, or to coincide with the
release of information on a new PCB, and may also contain addi-
tions or corrections pertaining to other parts of the manual.
If you return the address 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.
Revision Control 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 publica-
tion dates will be sent with each revision package.
Any portion of text that has been changed is marked by a verti-
cal 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 mar-
gin. The number beside the arrow will indicate how many para-
graphs have been deleted.
The manual issue and revision status are indicated by the last
three digits of the manual IPN. These digits start at 100 and will
increment through 101, 102, 103, etc., as revision packages are
published, e.g:
Thus, Issue 103 indicates the third revision to issue 1 and means
that three packages 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 PCB information is provided for all current issue PCBs, as well
as all previous issue PCBs manufactured in production quanti-
ties, and is grouped according to PCB. Thus, you will find the

it might be improved, please do not hesitate to contact the Tech-
nical Writer, Tait Radio Systems Division, Tait Electronics Ltd,

If further information is required about any ancillary equipment or this Manual, it may
be obtained from Tait Electronics Ltd or accredited agents. When requesting this infor-
mation, please quote the equipment type number (e.g. T807-10) and serial number. In
the case of the Service Manual quote the Tait Internal Part Number (IPN), e.g. M800-00-
100, and for circuit diagrams quote the 'Title', 'IPN' and 'Issue'.
1.1 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 proce-
dures refer to the manufacturers' data books, e.g. Philips data books covering CMOS
devices, or Motorola CMOS data books, Section 5 'Handling', etc.
Figure 1.1 Typical Antistatic Bench Set Up
An antistatic bench kit (refer to Figure 1.1) is available from Tait Electronics Ltd under
the usual consumable goods ordering system. The kit is held in stock under IPN
937-00000-34 and contains:
• 1 conductive rubber bench mat
• 1 earth lead to connect the mat to ground (c/w 1M series resistor)
• 1 wrist strap
• information leaflet.

1.2 Caution: Beryllium Oxide & Power Transistors
The power transistors in current use 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 power transistors should not be
broken open, mutilated, filed, machined, or physically damaged in any way that can
produce dust particles.

2.1 Pozidriv Recess Head Screws
Pozidriv recess head screws are the preferred standard on all Tait manufactured equip-
ment. The very real advantages of this type of screw will not be realised unless the cor-
rect screwdrivers are used by servicing personnel.
2.2 Disassembly/Reassembly
Instructions on disassembly/reassembly for individual equipment are given in the rele-
vant part of this manual.

3 Component Replacement
3.1 Leaded Components
Whenever components are removed from or fitted to a PCB, care must be taken to avoid
damage to the track. The two satisfactory methods of removing components from PTH
PCBs are detailed below.
Note: The first method requires the use of a desoldering station, e.g. Philips SBC
314 or Pace MBT-100E.
3.1.1 Desoldering Iron Method
Place the tip over the lead and, as the solder starts to melt, move the tip in a circu-
lar motion.
Start the suction and continue the movement until 3 or 4 circles have been com-
pleted.
Remove the tip while continuing suction to ensure that all solder is removed from
the joint, then stop the suction.
Before pulling the lead out, ensure it is not stuck to the plating.
If the lead is still not free, resolder the joint and try again.
Note: The desoldering iron does not usually have enough heat to desolder leads
from the ground plane. Additional heat may be applied by holding a sol-
dering iron on the tip of the desoldering iron (this may require some addi-
tional help).
3.1.2 Component Cutting Method
Cut the leads on the component side of the PCB.
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.
Fill the hole with solder and then clear with solderwick.

3.2 Surface Mount Devices
Caution: Surface mount devices (SMDs) require special storage, handling,
removal and replacement techniques. This equipment should be serv-
iced only by an approved Tait Dealer or Service Centre equipped with
the necessary facilities. Repairs attempted with incorrect equipment or
by untrained personnel may result in permanent damage. If in doubt,
contact Tait Electronics Ltd or your nearest Tait Branch or Subsidiary.

Copyright TEL 31/08/96
4 To Remove 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 equiva-
lent.

5.1 BASEPROG V1/PGM800 V2
T800 programming software was originally developed as BASEPROG V1 and released
as PGM800 V2.
5.2 PGM800 V2.01
The major changes introduced with V2.01 are as follows:
• Full support for different display adaptors.
• Programming of CTCSS frequency data (optional) for individual channels.
• Full cursor control in edit mode.
• User selectable output file format (hex or binary).
• Support for wider range of T800 equipment.
• DOS shell facility implemented.
• CTCSS defeat possible when CTCSS tone is not selected.
• Channel numbering changed from 0-127 to 1-128.
• An "X" included on the printout to indicate that there are 8 switches on the DIP
switch and the state of the MSB is dependent on the size of the EPROM used.
Note: The data files produced by BASEPROG V1.0 are still compatible with
PGM800 V2.01.

5.3 PGM800 V2.21
PGM800 V2.21 is an updated and expanded version of the earlier PGM800 V2.01 soft-
ware.
PGM800 V2.21 includes many new and improved features over PGM800 V2.01. There
are a number of changes to the user interface to make data entry and editing signifi-
cantly easier.
Major changes are outlined below:
• Includes several new radio models which are not programmable with PGM800
V2.01.
• Default file names with ‘dash’ are saved with ‘dash’ instead of ‘underscore’.
• Default file extension in Save File page is BIN instead of HEX.
• Out of range frequencies will result in warning messages, but will still be accepted
as valid entries.
• Channel numbers are selectable between 0-127 and 1-128.
• Automatic insertion feature to input frequencies.
Note: The datafiles produced by BASEPROG V1.0 and PGM800 V2.01 are still
compatible with PGM800 V2.21.
5.4 PGM800Win V1.00
PGM800Win V1.00 is different in concept from DOS versions of PGM800 in that it is
WindowsTM driven. It includes many new and improved features over DOS versions of
PGM800.
Major changes are outlined below:
• The Windows environment makes data entry and editing significantly easier.
• Includes several new radio models which are not programmable with DOS ver-
sions of PGM800.
