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 is also 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.
