Important Safety Notice
Proper service and repair is important to the safe, reliable operation of all ACER Company Equipment. The service
procedures recommended by ACER 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. ACER 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, ACER
has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool
which is not recommended by ACER 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, ACER Company will be referred to as ACER.
