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.

WARNING

Critical components having special safety characteristics are identified
with a A by the Ref. No. in the parts list and enclosed within a broken
line* (where several critical components are grouped in one area) along
with the safety symbol A on the schematics or exploded views.

Use of substitute replacement parts which do not have the same
specified safety characteristics may create shock, fire, or other
hazards.

Under no circumstances should the original design be modified or
altered without written permission from Philips. Philips assumes no
liability, express or implied, arising out of any unauthorized
modification of design. Servicer assumes all liability.
