1. CONTRAST

OF

MISCELLANEOUS PARTS

NOTES:

• Parts marked

by

"NSP" are generally unavailable because they are not

in

our Master Spare Parts List.

• The 6 markfound

on

some componentparts indicates the importance

of

the safetyfactor

of

the part. Therefore, when replacing,

be sure to use parts

of

identical designation.

• Parts marked

by"@"

are not always

kept

in

stock. Their delivery time

may

be longer than

u'sual

or they

may

be unavailable.

• When ordering resistors, first convert resistance values into code form as shown

in

the following examples.

Ex. 1 When there are 2 effective digits (any digit apart from

0),

such as 560 ohm and 47k ohm (tolerance is shown

by]

=

5%,

and K =

10%).
