Safety Summary
This informaton is intended as a guide for trained and
qualified personnel who are aware of the dangers involved in
handlingpotentiallyhazardouselectrical/electronicequipment.
It is not intended to contain a complete list of all safety
precautions which should be observed by personnel in using
this or other electronic equipment.
The installation, maintenance and service of this equipment
involves risks both to personnel and equipment and must be
performed only by qualified personnel exercising due care.
Personnelengaged in the installation,operation,maintenance
or servicing of this equipment are urged to become familiar
with First Aid theory and practises.
During installation and operation of this equipment, local
buildingsafetyand fire protection standards must beobserved.
Before connecting the equipment to the power supply of the

lead of the installation needs to be verified.
Whenever it is likely that safe operation is impaired, the
apparatus must be made inoperative and secured against any
unintended operation. The appropriate servicing authority
must then be informed. For example, safety is likely to be
impaired if the apparatus fails to perform the intended
function or shows visible damage.
This product has been designed and tested according to
EN60065.

When performing service, be sure to read and comply with
the warning and caution notices appearing in the manuals.
Warnings indicate danger that requires correct procedures or
practices to prevent death or injury to personnel. Cautions
indicate procedures or practices that should be followed to
prevent damage or destruction to equipment or property.
WARNING
THE CURRENT AND VOLTAGES PRESENT IN THIS EQUIPMENT ARE DANGEROUS.
ALL PERSONNEL MUST AT ALL TIMES FOLLOW THE SAFETY REGULATIONS.
ALWAYS DISCONNECT POWER BEFORE REMOVING COVERS OR PANELS.
ALWAYS DISCHARGE HIGH VOLTAGE POINTS BEFORE SERVICING.
NEVER MAKE INTERNAL ADJUSTMENTS, PERFORM MAINTENANCE OR SERVICE
WHEN ALONE OR WHEN FATIGUED.
INCASE OF AN EMERGENCY ENSURE THAT THE POWER IS DISCONNECTED.
ANY INTERRUPTION OF THE PROTECTION CONDUCTOR INSIDE OR OUTSIDE THE
APPARATUS, OR DISCONNECTION OF THE PROTECTIVE EARTH TERMINAL, IS

READ THIS INFORMATION CAREFULLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT
CAUTION
To prevent risk of overheating, ventilate the product
correctly.
Connect the product only to a power source with the
specified voltage rating.
Cathode ray tubes
Components marked on the circuit diagram are critical for
safety and include those specified to comply with X-ray
emission standards for units using cathode ray tubes and
those specified for compliance with various regulations
regarding spurious radiation emission.
When servicing units that use cathode ray tubes (CRTs), the
cathode ray tubes themselves, the high voltage circuits and
related circuits are specifically chosen so that they comply
with recognized codes pertaining to X-ray emission.
Consequently, when servicing, replace the cathode ray tubes
and other parts with specified parts only. Do not attempt to
modify these circuits as any unauthorized modification can
increase the high voltage value and cause X-ray emission from
the cathode ray tube.
Handle the cathode ray tube only when wearing shatterproof
goggles and after discharging the high voltage completely.
Symbol Colour Explanation

About This Manual
Purpose of this manual
The purpose of this manual is to present a global description
of how to operate the viewfinder. Consult the Operator's
manual of your camera as required during and after the
installation process.
This manual is an integral part of the service policy. It ensures
that you will be able to install your viewfinder to meet the
requirements of your environment. The manual provides 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. The guide
is so designed that it can be used as wel to the viewfinder, as
wel a simple procedural guide to those who wish to setup and
start shooting immediately, and as a reference work to be
consulted as required during the long life of the viewfinder.
Service policy

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 Broadcast
Solutions first line maintenance philosophy are speed and
cost effectiveness. First line maintenance is dedicated to
keeping your viewfinder operational, despite a fault, by
replacement boards and the replacement of minor mechanical
parts by the user.
CAUTION

protected according to safety specification EN60529
up to level IPX3 (spraying water). Exposure to
splashing or jetting water can result in harmful
effects.
Packing/Unpacking
Inspect the shipping container for evidence of damage
immediately after receipt. If the shipping container or
cushioning material is damaged, it should be kept until the
contents of the shipment have been checked for completeness
and the unit has been checked mechanically and electrically.
The shipping container should be placed upright and opened
from the top. Remove the cushioning material and lift out the

general instructions should be used for repacking with
commercially available materials:
a. Wrap unit in heavy paper or plastic.
b. Use strong shipping container.
c. Use a layer of shock-absorbing material around all sides
of the unit to provide firm cushioning and prevent
movement inside container.
d. Seal shipping container securely.
e. Mark shipping container FRAGILE to ensure careful
handling.
Storage
The unit may be stored (non-operating condition) in
environments within the following limits:
Temperature: -20 to +50 degrees C
