Service manual

• Do not use pliers to remove a MOS or CMOS device from a
high-grip socket. Instead, use a small screwdriver to pry the device
up from one end. Slowly lift the device up, one pair of pins at a time.
• After you remove a MOS or CMOS device from an assembly, place
the device onto a pad of conductive foam or other suitable holding
material.
• If a device requires soldering, be sure the assembly is placed on a
pad of conductive material. Also, be sure you, the pad, and the
soldering iron tip are grounded to the assembly. Apply as little heat
as possible when soldering.
