PRODUCT SAFETY NOTICE
Although the main chassis is insulated from mains, part of the power
supply chassis bears mains voltage. This therefore should not be
connected to earth during servicing.
Do not install, remove, or handle the picture tube in any manner unless
shatter-proof goggles are worn. People not so equipped should be kept
away while picture tubes are handled. Keep picture-tube away fron the
body while handling.
Before returning a serviced receiver to the customer, the service
technician must thoroughly test the unit to be certain that it is
completely safe to operate without danger of electrical shock, and be
sure that no protective device built into the instrument by the
manufacturer has become defective, or inadvertently defected during
servicing.
Therefore, the following checks are recommended for the continued
protection of the customers and service technicians.
INSULATION
Insulation resistance should not be less than 2 MOhm at 500 V DC
between the mains poles and any accessibe metal parts.
HIGH VOLTAGE
High voltage should always be kept at rated value of the chassis, no
higher. Operating at higher voltage may cause a failure of the
picture tube or of high voltage supply.
Furthermore, in no case whatsoever must the electrical circuit
providing the EHT be altered so as to prevent wrong voltage values
from causing ionizating radiations above those allowed by international
standards.
REPLACEMENT OF COMPONENTS
Some electrical components have special safety related characteristics
which are indicated on schematic diagram by the
Therefore, all components provided with this mark must be replaced with
original ones and their assembly must comply with the original assembly.
