Proper service and repair isimportant to the safe, reliable
operation of all HPConsumer Electronics Company**
Equipment. The service procedures recommended by HP and
described in this service manual are effective methods of
performing service operations. Some ofthese 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

EXHAUSTIVE. HP 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, HP has not
undertaken any such broad evaluation. Accordingly, a
servicer who uses a service procedure or tool which is not
recommended by HP must first satisfy himself thoroughly that
neither his safety nor the safe operation of the equipment will
be jeopardized by the service method selected.
