WHEN USING THIS SERVICE REFERENCE MATERIAL
1. How to Read Abbreviations
Values, dielectric resistances
(power capacitances),
tolerances,
grades of resistors
(excluding variable
resistors,
etc.)
and capacitors
are
indicated
in the schematic
diagrams using abbreviations.
Collate
these abbreviations
and
the following tables to read abbreviations
and replace parts
correctly.

Markings
in Schematic
and Circuit
Board Diagrams
(1) Parts with marks "I" attached to circuit numbers in the
schematic
and circuit board diagrams are discrete
cosponents.
(2) Parts with marks "@" attached to circuit numbers in the
schematic
and circuit board diagrams
are chip components.
(3) Parts with marks (2) in the circuit board diagrams are
leadless
jumpers.

Cautions
on Use of MOS
ICs
(1) MOS ICs are inserted in black foam for shipment.
This foam is a conductor which short-circuits
between
the leads
to prevent damage.
Do not remove
ICs from this
foam during storage.
Avoid removing
ICs from this foan,
placing
them on plastic which
is likely to be charged with
static electricity or inserting them into styrol foam.
(2) High voltages may be applied during soldering caused by
leakages
from the soldering
iron.
Be sure to ground
the tip of the soldering
iron or use a low voltage
soldering
iron.
(3) The human body and clothes made of synthetic fiber or
nylon gloves may be charged with several
thousand volts
of static electricity
because
of friction.
Workers
should be grounded.
