2. CONTRASTOF MISCELLANEOUSPARTS
NO?ES:
c Parts without part number cannot be supplied.
o The $ marh found on some component parts indicates the importance of the
safety factor of the part. Therefore, when replacing, be sure to use parts of identical
designation.
c For your Parts Stoch Control, the fast moving items are indicated with the marks
** and *,
** GENERALLY MOWS FASTER THAN *.
This classification shall be adjusted by eachdistributor because it depends on model
number, temperature, humidity, etc.

NO?ES:
o When ordering resistors, first conuert resistanceualuesinto 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 47h ohm (tolerance
is
shown by J: 57o,and K = 10V").
