Manpack Transceiver 2110 series Repair Guide 1
Introduction
Overview of this guide
This Repair Guide is intended for use by personnel at Codan-trained Service Centres and
Accredited Service Centres, enabling rapid and cost-effective servicing of the
2110 series Manpack Transceiver.
This guide provides an overview of the equipment and its specifications, functional
descriptions, fault diagnosis to board level, board replacement, functional testing and
interconnection drawings for the 2110 series Manpack Transceiver. The fault diagnosis
and testing procedures provided assume that the transceiver does not have any hardware
options fitted. A list of available hardware options is included with this guide.
This guide assumes that you have a good understanding of electronics with a technical
background, and that you understand operation and setup processes for the transceiver. It
also assumes that you have access to the relevant Getting Started Guide or Reference
Manual for your manpack transceiver.
This guide contains the following sections:
Contact information—provides details of how to access up-to-date contact information
from Codan’s website
Ordering information—explains the details required by Codan to ensure prompt service
and delivery
Overview—general description of the 2110 series Manpack Transceiver
Brief description—brief technical description of the 2110 series Manpack Transceiver
including a general description of the major circuit functions for the control, reception
and transmission of signals
Interconnection diagrams and listed spares drawings—provides drawings that are
required during repair of a 2110 series Manpack Transceiver
Functional description of PCBs—functional description of each PCB, including a list of
test points and PCB layouts
Repair procedures, tests, and adjustments—provides flowcharts and tests for identifying
faulty subassemblies, and a test sheet for recording test data
Options—provides drawings and instructions for identifying and checking correct
operation of hardware options in the transceiver
Definitions—lists all standards, acronyms, abbreviations and units used in this guide
Specifications—provides specifications for the 2110 series Manpack Transceiver

How to use this guide
The printed version of this guide supplied by Codan contains pages that fold out beyond
the folder on either side. This enables you to view block diagrams, test-point layouts and
flowcharts while reading relevant text on tests and procedures.
Begin the fault diagnosis process by using the Repair flowchart (see Figure 29 on
page 95). The same flowchart is also used to confirm that a transceiver is operating
correctly.
Follow the steps in the Repair flowchart systematically to ensure the correct fault is
isolated. If you step out of the flowchart to a test procedure, return to the same point on
the flowchart upon completing the test, and continue as prompted.
At some points where a pass criteria is not met, the Repair flowchart refers to a function-
specific fault diagnosis flowchart. Some steps require a simple task to be performed.
Other steps require a test to be performed. In such a case, the PCB, test point, and test
condition are provided.
Board replacement philosophy
To facilitate rapid and cost-effective servicing, and to effectively manage the increasing
sophistication of electronic assemblies, a strategy of board replacement applies to all
2110 series Manpack Transceivers.
As part of this strategy, all boards are designed and tested so that any individual board
can be replaced, while maintaining factory specifications of the entire unit.
If functional spare boards are held in stock, they may be substituted during the fault
diagnosis process in order to positively localise the fault to one board.
Disposal
Depending on the regulations within your country, some items from the transceiver may
need to be returned to a recycling facility for correct disposal. Please be aware of any
such regulations in your country and act accordingly.
Please be aware of your organisation’s policies for safeguarding the disposal of security
products. Please contact your Codan representative for further information on this
matter, if required.
NOTE
Not all faults may be diagnosed from the fault diagnosis flowcharts due to
the complex nature of the transceiver. In such an instance, or to confirm
that a PCB is faulty, see page 27, Functional description of PCBs.
CAUTION This product contains lead solder.

Circuit board precautions
Connection/Disconnection
Ensure that any power supply or battery is switched off or disconnected before making
connections or disconnections between circuit boards.
Handling
Handle circuit boards by the edges only. Use antistatic bags or trays to store and transport
PCBs.
Grounding
Ground any items that may come into contact with the circuit board as follows:
• Discharge static charges, which may build up on a person, by touching a grounded
metal surface with both hands. This should be done before working on circuit
boards, and at frequent intervals while working on circuit boards.
• Wear a suitably grounded conductive wrist strap and use an anti-static mat. This
minimises the build up of static on you.
• Ensure that all test equipment is properly earthed through its power connection or by
earthing it to the workbench or anti-static mat.
Soldering
Excessive heat from soldering may lift tracks from the circuit boards and cause serious
damage. Avoid the use of high-powered soldering irons. A soldering iron rated at a
maximum of 60 W, preferably temperature-controlled at approximately 370°C, is
sufficient for most tasks. A soldering iron rated at a slightly higher temperature of 425°C
may be required for heavier components such as PA transistors. Only apply the soldering
iron long enough to de-solder an existing joint, or to solder a new one.
De-soldering
When de-soldering a component, use a solder sucker or solder wick to remove existing
solder.
A special de-soldering station is recommended for plated thru-holes.
CAUTION Do not use lead-free solder for new soldering work.
CAUTION
Do not use sharp metal tools such as screwdrivers or twist drills to remove
components as these may damage the printed circuit track and plated thru-
holes.

Introduction

Transmitter precautions
When making measurements of the low-level stages of the exciter, it is advisable to
remove the drive to the PA & Filter PCB. The supply voltage is applied to the PA at all
times when the transceiver is switched on.
Probe precautions
Observe the following when connecting oscilloscope probes to the transceiver:
• When connecting probes to the PA assembly, the earth clip lead should be wound
around the body of the probe so that the earth clip can be earthed to the ground plane
as close as possible to the point of measurement. This reduces stray RF pick-up.
• It is not advisable to connect two probes at the same time, particularly when one is
earthed to the PA ground plane and the other is earthed to the exciter. This may
cause earth loop problems.
• Probes should be connected before power has been applied to the transceiver and the
test equipment. The earth connection should be made first and disconnected last.
CAUTION Caution should be exercised when connecting test equipment to avoid
incorrect readings and/or damage.
