Safety Summary
This informaton is intended as a guide for trained and qualified personnel who are aware of the dangers involved in handling potentially hazardous electrical/electronic equipment. 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.
Personnel engaged 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 building safety and fire protection standards must be observed.
Before connecting the equipment to the power supply of the installation, the proper functioning of the protective earth 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.
Cautions and Warnings
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.
A
LL PERSONNEL MUST AT ALL TIMES FOLLOW THE SAFETY REGULATIONS.
ALWAYS DISCONNECT POWER BEFORE REMOVING COVERS OR PANELS.
A
LWAYS DISCHARGE HIGH VOLTAGE POINTS BEFORE SERVICING.
NEVER MAKE INTERNAL ADJUSTMENTS, PERFORM MAINTENANCE OR SERVICE
WHEN
ALONE OR WHEN FATIGUED.
IN CASE 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
LIKELY
TO MAKE THE APPARATUS DANGEROUS. INTENTIONAL INTERRUPTION IS
PROHIBITED

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
Red High voltage terminal at which a
voltage, with respect to an other terminal, exists or may be adjusted to 1000V or more.
Yellow/Black Live part.
Yellow/Black This marking indicates that the
operator must refer to an explanation in the Instruction Manual, or that a specific component must be replaced by the component specified in the documentation for safety reasons.
White/Black Protective earth (ground) terminal.

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
The LDK 5305 is a sophisticated viewfinder containing state­of-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
Without additional protection the LDK5305 is 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 contents.
The contents of the shipment should be checked against the packing list. If the contents are incomplete, if there is mechanical damage or defect, or if the unit does not perform correctly when unpacked, notify your Thomson Multimedia Broadcast Solutions sales or service centre within eight days. If the shipping container shows signs of damage or stress, notify the carrier as well.
If the unit is being returned to Thomson Broadcast Solutions for servicing, try to use the containers and materials of the original packaging. Attach a tag indicating the type of service required, return address, model number, full serial number and the return number which will be supplied by your Thomson Broadcast Solutions service centre.
If the original packing can no longer be used, the following 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
Humidity: Up to 90%
Altitude: 50,000 feet
When stored, the unit should be protected from temperature extremes which may cause condensation, and should also be protected from high levels of dust.
