ii User's Guide LDK 4502 - HDTV Camera Base Station 02.34.3
About This ManualService policy
The Camera Base Station is a sophisticated base station
containing state-of-the-art electronic components which
are designed to provide long-life operation without the
need for maintenance. With this in mind, the service policy
of Thomson Multimedia Broadcast Solutions endeavours
to ensure that help will be quickly on hand in the unlikely
event of anything going wrong. The guiding principles of
the Thomson Multimedia Broadcast Solutions first line
maintenance philosophy are speed and cost effectiveness.
First line maintenance is dedicated to keeping your base
station operational, despite a fault, by module replacement
and the replacement of minor mechanical parts by the
user.
Purpose of this manual
The provision of correct information is the first step in
ensuring the operational integrity of the base station.
Information on the operation of the base station is contained
in Section 3 of the manual.
This User's Guide is an integral part of the service policy.
It ensures that you will be able to operate, install and set-
up your base station to meet the requirements of your
environment. The information on the installation of the
base station is contained in Section 2 of the manual. The
remaining sections of the manual provide first line service
information so that suitably qualified service personnel can
detect and repair faults, normally by module replacement.
Because of the complexity of some of the components,
second line service can only be carried out at the specially
equipped service centres and information concerning
second line maintenance is not supplied
in this manual.
Intended audience
The manual is intended as a guide to those with a working
knowledge of camera systems and installation techniques.
The first line detection and repair of faults requires a
general knowledge of test and measurement techniques.
Structure of this manual
The manual is divided into eight different sections:
Section 1: Safety Instructions
Outlines the safety precautions that must be taken when
using the base station.
Section 2: Installation
Gives instructions on the integration of the base station into
the operating environment and the customization of certain
functions.
Section 3: Operating instructions
Explains how to program the menu system for your personal
preferences. The menu structure and the methods of
function selection are also explained. An appendix to this
section lists all the menu functions.
Section 4: Replacements
Gives information on the replacement of components at
first line level.
Section 5: Diagnostics
Gives a guide to diagnostic messages and procedures for
fault-finding.
Identification and Status
To indicate the status of a drawing, a box with the numbers
0 to 9 is shown in the bottom-right of the drawing. The
number that is crossed-out is the status number of the
drawing. For example, in the illustration below, the status
is 1.
A sticker is used on the units themselves to identify them
and to indicate their status. For example, in the illustration
below, the top line is the 12-digit number that identifies the
unit type.
The first four digits of the number on the second line
represent a date code (year, week); the next four digits
represent the serial number for that week.
The number in the grey area indicates the status of the unit.
The last two digits represent the number that will be given
to the next status. However, if these two digits are contained
in a box, then this is the current status. For example, in the
illustration above, the current status of the unit is 01.
