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.

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.
