GENERAL SAFETY NOTES
IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all Philips Consumer Electronics
Company** equipment. The service procedures recommended by Philips and described in this service
manual are effective methods of performing service operations. Some of these service operations require
the use of tools specially designed for the purpose. The special tools should be used when and as
recommended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be
carefully read in order to minimize the risk of personal injury to service personnel. The possibility exists
that improper service methods may damage the equipment. It also is important to understand that
these
CAUTIONS and NOTICES ARE NOT EXHAUSTIVE . Philips could not possibly know, evaluate
and advise the service trade of all conceivable ways in which service might be done or of the possible
hazardous consequences of each way. Consequently, Philips has not undertaken any such broad
evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by
Philips must first satisfy himself thoroughly that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.
** Hereafter throughout this manual, Philips Consumer Electronics Company will be referred to as
Philips.
